Roof boiler rooms for apartment buildings design standards

Types and arrangement of roof boiler houses

The standards separately stipulate the possibility of operating a boiler room of built-in and block-modular type. Each type of technical and design solution has its own limitations and features. In general, placing boiler equipment on the roof has several advantages:

• There are no costs for the construction of a separate technical building.
• There is no need to build a high chimney.
• The safety of operating heating equipment increases.

Block-modular roof boiler houses

The following steps are required for installation:

• A platform is installed, supported by load-bearing walls and other building structures. Before installation, an examination is carried out aimed at determining the load-bearing capacity and identifying measures to strengthen the structurally significant elements of the building.
• The covering under the boiler room is made from non-combustible materials. As a rule, a concrete pad with a thickness of 20 cm is poured for this.
• Separate measures are provided to ensure safety (manufacture of railings around the perimeter of the roof) and increase the sound insulation of the modules.

Installation of block-modular heating equipment requires the preparation of a separate project and is suitable for buildings in which it was not initially planned to heat the premises in this way.

A modular boiler house is a fully equipped thermal station, ready for operation. All equipment is built into the module. The BMK is additionally equipped with rooms for service personnel.

Built-in roof boiler rooms

It is much easier to produce and approve a project for a built-in boiler room. Soundproofing, noise-absorbing and anti-vibration measures are carried out simultaneously with the construction of walls and finishing work, which significantly increases their effectiveness. In fact, built-in boiler rooms are provided extremely rarely, mainly in new houses, the construction of which began in the last 5 years.

Rooftop boilers

Domestic thermal units, for all their advantages, are not autonomous. Therefore, the choice mainly falls on products from Italian, German and other European manufacturers:

• Futera.
• Rendamax.
• Wessex.
• Viessmann.
• Buderus.
• Protherm.
• Ferroli.
• Vaillant.
• Lochinvar.

When choosing a suitable boiler, they are guided by thermal power, availability of registration and license issued by Rostechnadzor, adaptation to domestic operating conditions and cost.

Types of roof boiler houses

The most acceptable option for placing such a boiler room is a flat roof structure. For these heat supply sources, installations are provided: built-in and block-modular boiler house (BMK).

BMK

Block-modular boiler houses operating on gas are supplied in full factory configuration. They arrive to the customer essentially 100% ready, so they are launched in the shortest possible time. Modern rooftop boiler houses operate all year round in automatic mode for heating and hot water supply and do not require permanent operating personnel.

All boiler equipment is selected according to design technological parameters and complies with current legislation in terms of ensuring safe operation. The unit includes boilers taking into account peak power, pumps for heating and hot water supply, fans and smoke exhausters, chimneys, primary thermal process control devices and an automatic control system. BMK is equipped with high-quality insulation and reliable supply and exhaust ventilation.

Built-in

A built-in roof boiler room in an apartment building is built in accordance with an individual project, in which each element of the thermal circuit is carefully calculated to create a safe and efficiently functioning heat supply system.

The boiler room is most often made of prefabricated sandwich-type structures or standard reinforced concrete products. The thermal circuit of the boiler room is assembled on site, using precisely selected equipment, developed diagrams of the built-in boiler room, in accordance with design specifications for equipment and materials.

The assembly is carried out by the customer of the facility or, under a separate agreement, with the installation organization. The scheme of a roof boiler house in a built-in apartment building includes gas boilers with reserves, pumping equipment, a smoke removal and ventilation system, chemical water treatment and instrumentation.

Typically, such boiler houses are installed within a few days, then the process of setting up the boiler equipment begins and the final stage of accepting the boiler house into operation.

Cost of a boiler room on the roof

• The type of boiler chosen - the boiler room is assembled and equipped at the request of the customer. Budget versions are equipped with boilers from Italian and Polish manufacturers. The most expensive station will be one equipped with German boilers Viessmann and Buderus.
• Additional work - in addition to installing a boiler room, measures are taken to eliminate structural noise, install a fire extinguishing system, power supply, etc. Total costs will increase by approximately 30% compared to the cost of the thermal plant.
• Boiler house insurance – annual costs for purchasing an insurance policy are mandatory, without which it will be impossible to put a rooftop boiler house into operation.

The total cost, including the preparation of design documentation and obtaining all necessary approvals, costs 5-10 million rubles, depending on the number of residents and the selected power of the heating equipment.

Roof boiler room - pros and cons

When determining whether a rooftop boiler room is a viable option for heating a residential building, the advantages and disadvantages are considered separately

Pay attention to the opinions of experts and reviews of consumers themselves

Advantages of a boiler room on the roof

• The supply of coolant and hot water in a multi-storey building with a rooftop gas boiler room is carried out directly to the building on which the station is installed. This leads to a reduction in heat loss when delivering coolant from the boiler room to the consumer. There is no need to pay for heat losses that exist with centralized city heating.
• Due to the complete automation of the heating process, the fee for maintaining the boiler room is reduced to a minimum. If necessary, an agreement is concluded with a contractor who simultaneously services several thermal stations.
• The heating season begins when necessary, and is not equated to a specific date.
• High safety - the gas boiler room is designed in such a way as to ensure maximum operational safety. The prevention of emergency situations is facilitated by many requirements and approvals that boiler equipment undergoes before it is put into operation.

Disadvantages of roof-mounted boiler houses

• Installation restrictions - for a roof boiler room, the number of storeys allowed is no higher than 9 standard floors. As mentioned above, this requirement can be challenged, but this does not always work out in practice.
• Problems with vibration – powerful circulation pumps operate in the boiler room; turbines are located in the boiler, producing high-intensity noise and vibration. And these are significant disadvantages for residents of the top floor.
• High cost - production and purchase of design documentation, noise insulation work, etc., will cost 5-10 million rubles. To save money, they order a turnkey boiler room.
• Disadvantages of rooftop boiler houses at the regulatory level - as already indicated, many officials in design organizations cite outdated building codes as the main requirements. To “convince” them may require repeated appeals to the courts. It all depends on the region where the documents are processed and the officials themselves.

Operating principle of roof boiler rooms

Modular rooftop gas boiler room
Rooftop gas boiler room is a self-contained modular type installation. The equipment includes thermal and control modules, automatic control and circulation pumps. The power of the rooftop boiler room will directly depend on the number of thermal modules. All elements are connected together into one heating system.

The automatic boiler room system performs the following “works”:

• local control over pressure and temperature parameters;
• alarm is triggered when an autonomous boiler room enters the building illegally;
• automatic regulation of the supply water temperature taking into account the pressure drop in the return pipeline;
• when gas contamination appears, the gas supply to the boiler room is automatically turned off and the exhaust fan starts;
• turning on backup network pumping equipment and a hot water supply pump;

In the event of a fire or severe gas pollution in the room, the operation of the supply fan, which is responsible for supplying air to the system, is automatically suspended.

Gas roof boiler room

The device has the following positive aspects:

• High efficiency. Thanks to the use of liquefied gas, which releases energy when heated, fuel consumption is reduced.
• There are almost no external communications. This reduces costs. Heat loss is also reduced.
• In low buildings (up to 26 m) there are no additional installation requirements, which reduces the cost of the project.
• Automation, which reduces operating costs.
• The device is not turned off for annual inspection, which allows daily use of hot water.

The device has several limitations. To accommodate the boiler room, the roof is strengthened by installing a concrete pad. Preliminarily calculate the load that the building can withstand.

Special equipment is brought in for installation, the operation of which creates inconvenience for residents. The cost is also unpleasant: the costs go towards creating the project, laying the gas carrier, and the automation responsible for control. Additionally, protective measures and a fire extinguishing system are installed.

Advantages and disadvantages

The device is installed directly on site.
Roof boiler rooms in apartment buildings and various enterprises are being installed more and more often due to the advantages of the equipment:

• Economical. The equipment is installed directly on site; people do not need to buy/lease additional territory for the construction of a boiler house. The most affordable type of fuel today is gas.
• Environmentally friendly, since the raw materials used for heating are clean and safe. When burning gas, the damage to the environment is minimal.
• High efficiency. This type of autonomous heating systems runs only on gas, and gas installations are considered the most efficient. The efficiency of gas boiler houses reaches 95%.
• Full automation of the process. Thanks to the modern automated system that the boiler room is equipped with, uninterrupted operation without human intervention is guaranteed. Automation monitors the indicators of all important parameters, even taking into account the weather conditions outside the window. This approach provides additional fuel savings.

Despite the large number of advantages, there are also disadvantages. The main ones:

• The installations are allowed to be installed on buildings no higher than 9 floors.
• High cost of equipment, installation, connection.
• Pumps produce strong vibration waves during operation, which can cause inconvenience to residents.

For residents of old houses, installing an autonomous heating system is not always possible. Not every structure can withstand such loads.

Installation

To create a heating system on the roof, you need to build a separate room. The roof boiler room is autonomous: once it is started, it is enough to carry out rare scheduled checks.

The process depends on the device variant. There are 2 types - built-in and block-modular.

Built-in

Boiler rooms built into the roof are used in new buildings. Such a device is installed only in a building under construction or in a building that has space to accommodate a thermal station. For built-in boiler rooms, the additional load on the walls of a multi-story building must be calculated and a fire extinguishing module must be created.

The main advantage of the device is the ease of creating and implementing a project. Along with the installation, work is carried out to install sound-absorbing coatings and vibration protection. Conducted at the finishing stage, they are more efficient during operation.

Block-modular

To place a roof boiler room in a constructed building, a block-modular type is used. The most common installation option is during a major overhaul. A roof boiler room is installed in case of restoration of the heating system. The project is created based on the characteristics of the building. The device is then created and delivered to the required building.

Before installation, the roof is inspected:

• Check the condition of the load-bearing supports.
• Apply a protective coating to the installation point. It is a concrete pad.
• Sound-absorbing material is installed.

Having completed the preparation, the boiler room is connected to the heating network. It is set up and the coolant is distributed. Having connected to the heating, they begin operation.

What to pay attention to

Before installing the device, it is necessary to take into account that it creates a load on the structure. Because of this, the following rules must be observed:

• It is prohibited to place the boiler room on the ceiling above residential premises.
• It is prohibited to place equipment in premises adjacent to residential premises.
• When designing, the size of the house in which it is planned to be located is observed.
• When designing, an emergency shutdown system is created.

Types of boiler houses

Block-modular type
The technical and operational characteristics of the building, its type, condition and purpose determine the type of roof boiler room used:

• block-modular type;
• built-in type.

The first type is used if an autonomous heating system needs to be installed in an already constructed building. They are installed, as a rule, during major renovations, where the built-in heating system needs modernization.

The design of an autonomous gas roof boiler house is created taking into account the technical features of the structure. The finished system is transported to the site and installed in a specific, pre-agreed location.

Before installing the equipment, the main elements of the structure are carefully checked

Before proceeding with the installation of block-modular boiler rooms, it is important to properly prepare the roof covering for the upcoming loads:

• Specialists check the condition of the main elements of the structure, especially load-bearing walls.
• A protective coating is applied to the installation site. As a rule, a concrete pad with a thickness of at least 20 cm is used.
• A set of measures must be taken to ensure safety precautions and enhance sound insulation.
• After installation, power plants are connected to the heating network of the structure, creating a single system. The operating mode is regulated directly on site and connections to the water supply and heating systems are made.

Despite the full automation of operation, the boiler room is equipped with a special room for maintenance personnel.

Positive and negative qualities

Gas heating of an autonomous apartment has many positive aspects, but, basically, it will be important only for owners of certain systems:

• Owners of this type of heating system pay based on the heat they use. That is, there is no need to overpay taking into account the delivery of heat from sources to the apartment itself, and this saves about 30% of your possible costs.
• The owners themselves can regulate the temperature in their apartment and the period of heat supply in it without restrictions.
• Availability of hot water in the apartment all year round.

But there are also negative aspects to an autonomous heating system:

• Possibility of problems with heating and hot water during gas pressure interruptions.
• Additional costs for boiler repair and maintenance, as well as chimney cleaning.

Let's do the calculation

Knowing that 100 watts of heat is needed per 1 square meter of room area, you can easily calculate the number of radiators needed. Therefore, you first need to accurately determine the area of ​​the room where the batteries will be installed.

Be sure to take into account the height of the ceilings, as well as the number of doors and windows - after all, these are the openings through which heat evaporates most quickly. Therefore, the material from which doors and windows are made is also taken into account.

Now the lowest temperature in your region and the coolant temperature at the same time are determined. All nuances are calculated using coefficients that are included in SNiP. Taking these coefficients into account, the heating power can be calculated.

A quick calculation is made by simply multiplying the area of ​​the room by 100 watts. But this will not be accurate. Coefficients are used for correction.

Power correction factors

There are two of them: decrease and increase.

Power reduction factors are applied as follows:

• If plastic multi-chamber double-glazed windows are installed on the windows, then the indicator is multiplied by 0.2.
• If the ceiling height is less than standard (3 m), then a reduction factor is applied. It is defined as the ratio of the actual height to the standard height. Example - the ceiling height is 2.7 m. This means that the coefficient is calculated using the formula: 2.7/3 = 0.9.
• If the heating boiler operates with increased power, then every 10 degrees of thermal energy it generates reduces the power of the heating radiators by 15%.

Power increase factors are taken into account in the following situations:

1. If the ceiling height is higher than the standard size, then the coefficient is calculated using the same formula.
2. If the apartment is corner, then a coefficient of 1.8 is used to increase the power of heating devices.
3. If radiators have a bottom connection, then 8% is added to the calculated value.
4. If the heating boiler lowers the temperature of the coolant on the coldest days, then for every 10 degrees of decrease it is necessary to increase the battery power by 17%.
5. If sometimes the temperature outside reaches critical levels, you will have to increase the heating power by 2 times.

Where should the boiler room be located?

A very serious issue is the correct location of the boiler room. Most often, in apartment buildings, boiler rooms are installed either on the roof or in the basement. provide for the presence of the latter only in the basement or.

True, sometimes you can also see boiler rooms located in small buildings located a few tens of meters from the house. This can be a good solution: there is no need to lift and install equipment on the roof of the building, but at the same time there is no threat of explosion due to fuel leakage and its accumulation in the basement of the building.

But still, this method is not very popular: the need for additional construction, pouring the foundation and carrying out a large amount of earthwork scares off many potential owners of autonomous heating boilers. Therefore, only two options are usually considered - a boiler on the roof and in the basement. And it’s worth talking about them in a little more detail.

Where can you place an autonomous boiler room?

It is very important to choose the right place to install heating units. Thus, a gas boiler room on the roof of a high-rise building is considered the most preferable option. They are often also installed in basements or ground floors.

To service a boiler room, it is enough to hire just one specialist, and this is a real saving of money every month

Of course, the best option in terms of safety and ease of maintenance is to erect a separate building near a residential building. Residents will not be threatened by possible fuel leaks or gas accumulation in the basement.

But you will have to build an additional building, lay a foundation for it, do a lot of ground work, and draw up a number of documents. This immediately scares off potential investors. Therefore, a basement or roof gas boiler room can be considered the best options.

Advantages

In order for the roof boiler room of a residential building to operate stably, it is necessary to carry out careful calculations and not skimp on installation. Equipped on the roof of a house, it has advantages over other systems:

• Installed on the roof of the house, the boiler room reduces energy losses during the transfer of coolant from roof equipment to radiators. This reduces the cost of heating services by up to 30%.
• Automation serves to use hot water during periods of absence, when the supply is turned off to check the media.
• Maintenance of the device is reduced due to autonomy. Functionality checks are carried out rarely, by agreement with the service company.
• Before operation, many checks are carried out to detect malfunctions and safety errors.

How to calculate the heating batteries of your own apartment

Calculation of the number of sections of heating radiators

Heating radiators are the most common heating device that is installed in residential, public and industrial premises. It consists of hollow elements filled with coolant. Through them, thermal energy enters the room to heat it.

When choosing radiators, you must first pay attention to two technical indicators. This is the power of the device and the coolant pressure it can withstand.

But in order to finally determine the temperature regime of the room, it is necessary to carry out an accurate calculation of the heating radiators.

This includes not only the number of devices themselves and their sections, but also the material from which they are made. The modern heating equipment market offers a huge range of batteries with different technical characteristics. The main thing you need to know is the capabilities of one section of the battery, namely, its ability to release the maximum amount of thermal energy. This indicator will form the basis for the calculation for the entire heating system.

Help from specialists

If at this moment it is suddenly unclear to you how to install heating in an apartment, then for this you need to contact qualified specialists. They will tell you everything and recommend how to choose the optimal parameters. First, a project is carried out, which shows an approximate layout of the heating system in the room.

After all the nuances have been clarified and approved, you can purchase equipment and ask about additional heating solutions in the house. The main thing is not to allow initiative in this matter, otherwise the system may break down and flood the neighbors, who are unlikely to be grateful to you for such a gift.

Types of gas boiler houses

The following types of equipment can be installed:

• block-modular. It is distinguished by mobility, versatility, and an attractive price. Gas boiler houses of this type can be used to heat residential buildings, as well as administrative buildings, schools, medical institutions, etc. Structurally, they are a container made of sandwich panels;
• roof It is located on the roof in a specially built room or block module. Typically, such a gas boiler room belongs to one building, therefore, it becomes possible to turn the heating on or off as needed by the residents. The equipment can be installed on houses that have no more than 10 floors;
• emergency. It is delivered on a trailer and quickly connected to the facility. Used in case of breakdown of a stationary boiler room;
• built-in It is located in a special room inside the building. Such gas boiler houses are not intended for heating residential buildings, schools, hospitals and other structures where people are constantly present. When operating them, conditions should be ensured under which the gas pressure does not exceed 5 kPa.

All gas boiler houses from Teplostroy LLC operate automatically without the need for the participation of technical personnel. Monitoring and processing of possible equipment emergencies occurs using remote control by a dispatcher. Basic parameters (pressure, temperature, flow, etc.) are constantly transmitted to the command post. Emergency signals are immediately sent via cellular or radio to the control panel.

Roof boiler rooms for apartment buildings design standards - Safety Portal

Calculators SNiPs and GOSTs

Roof boiler rooms were invented specifically so that their design could be done on the roofs of apartment buildings. It can also be installed on separate structures that are installed on special bases.

Rice. 1 Roof boiler room

Roof-top gas boiler houses are installed on houses in those places where designing and complying with the standards of a centralized gas main is, in principle, impossible.

If buildings in large cities with reconstruction and spot construction are located in the city center, then the norm for the construction of elite complexes is the design of roof-top boiler houses.

Operating principle, characteristics and design features of modern gas boiler houses

Gas installations are actively used in many industries; they can be used to provide hot water supply and thermal energy to construction sites, administrative buildings, agricultural facilities, etc. They are safe, efficient and economical. The units are capable of operating on gas:

• natural;
• liquefied;
• associated oil.

Gas autonomous boiler houses have the following devices and equipment as standard:

• steam or hot water boiler;
• burner;
• supply line;
• gas network pumping equipment;
• instrumentation devices;
• security systems and elements.

The operating principle of gas boiler houses is relatively simple:

• gas waste enters the boilers, while fuel can come from the main line or gas holder;
• the gas goes directly to the burner located in the boiler;
• fuel is ignited and burned. As a result, the coolant heats up;
• the coolant enters the radiator batteries, the “warm floor” system, etc. During circulation, it cools down and then returns back to the boiler, after which the cycle is repeated;
• combustion products are discharged outside through the chimney.

The use of such boiler houses is economically justified. The ability to independently regulate the heat supply allows you to significantly reduce the cost of hot water supply and heating and at the same time not depend on utility services.

How to reduce current heating costs

Central heating scheme for an apartment building

Considering the constantly increasing tariffs for housing and communal services payments for heat supply, the question of reducing these costs becomes only more relevant every year. The problem of reducing costs lies in the specifics of the centralized system.

How to reduce heating bills and at the same time ensure the proper level of heating of the premises? First of all, you need to understand that the usual effective methods for reducing heat losses do not work for central heating. Those. if the facade of the house was insulated, window structures were replaced with new ones, the payment amount will remain the same.

The only way to reduce heating costs is to install individual heat meters. However, you may encounter the following problems:

• A large number of thermal risers in the apartment. Currently, the average cost of installing a heating meter ranges from 18 to 25 thousand rubles. In order to carry out heating cost calculations based on an individual device, it is necessary to install them on each riser;
• Difficulty in obtaining permission to install a meter. To do this, it is necessary to obtain technical specifications and, based on them, select the optimal model of the device;
• In order to make timely payments for heat supply using an individual meter, it is necessary to periodically send them for verification. To do this, dismantling and subsequent installation of the device that has passed verification is carried out. This also entails additional costs.

The principle of operation of a common house meter

But despite these factors, installing a heat meter will ultimately lead to a significant reduction in payments for heating services. If the house has a circuit with several thermal risers passing through each apartment, you can install a common house meter. In this case, the cost reduction will not be so significant.

When calculating payment for heating using a common house meter, it is not the amount of thermal energy received that is taken into account, but the difference between it and the return pipe of the system. This is the most acceptable and open way to formulate the final cost of the service. In addition, by choosing the optimal model of the device, you can further improve the heating system of your home according to the following indicators:

• The ability to regulate the amount of thermal energy consumed into the building depending on external factors - outside temperature;
• A transparent way to calculate heating payments. However, in this case, the total amount is distributed among all apartments in the house depending on their area, and not on the volume of thermal energy that came to each room.

In addition, only representatives of the management company can maintain and set up a common house meter. However, residents have the right to demand all the necessary reporting to reconcile completed and accrued housing and communal services payments for heat supply.

In addition to installing a heat meter, it is necessary to install a modern mixing unit to regulate the degree of heating of the coolant entering the heating system of the house.

What is a block boiler installation?

• hot water boiler, fuel combustion chamber, heat exchangers;
• pumps for circulating water in the system;
• equipment for water treatment and purification;
• flues, chimneys;
• gas equipment (when using gas);
• DHW circuit equipment (if any);
• automatic control and dispatch system, instrumentation.

By type of fuel consumed

There are
gas, solid and liquid fuel
units. Combinations of several fuel types are possible. Gas boiler houses are most widespread due to their high efficiency (up to 95%), and they are also the most environmentally friendly. Solid fuels include coal, firewood, peat, pallets, liquid fuels include fuel oil, diesel fuel, waste oil.

By type of execution

The following boiler plant modules are distinguished:

The latter version is gaining popularity due to its technical and economic advantages, as well as better safety and environmental characteristics.

Roof boiler room in an apartment building 2021

Roof boiler rooms were invented specifically so that their design could be done on the roofs of apartment buildings. It can also be installed on separate structures that are installed on special bases.

Rice. 1 Roof boiler room

Roof-top gas boiler houses are installed on houses in those places where designing and complying with the standards of a centralized gas main is, in principle, impossible. If buildings in large cities with reconstruction and spot construction are located in the city center, then the norm for the construction of elite complexes is the design of roof-top boiler houses. And all due to the fact that the area is small and, accordingly, the price norm for purchasing land is very high, so it is impossible to install stationary centralized heating systems.

Rice. 2 Roof gas boiler room

Roof boiler rooms can be installed during the reconstruction of apartment buildings and when designing new tall buildings.

Building design is possible in two options:

• The first option is the so-called frame structure, which is arranged in blocks. For this option, it is necessary to erect a special building. Designing roof units in this form is suitable for new multi-apartment buildings.
• The second option for designing boiler houses is roof-mounted gas boiler houses with block modules. Sandwich panels are used for their design and construction.
• Roof boiler houses have 2 types of boiler applications: steam boiler units and water heating equipment.

Rice. 3 Gas equipment on the roof

Roof boiler rooms for apartment buildings are a modern solution to the problem of designing autonomous heating without connection to a centralized gas main. After all, modern building construction sometimes requires standards that cannot be implemented. Heat loss, thanks to this design of heating for apartment buildings, is low, so installing a rooftop boiler room is even the norm for an economical option.

The popularity of rooftop gas boiler houses is growing every day, since thanks to this heating design, the costs of land allocation will disappear, and there will be no need to design a heating main. And even the temperature can be set more accurately.

What other advantages does designing rooftop boiler houses have? Are there any disadvantages to using it for apartment buildings? Are there safety regulations that must be followed when designing boiler rooms on rooftops?

The requirements and standards for the design and installation of this structure are not significant at all, but still, they exist. Since safety is the main thing in our world, and first of all we need to take care of it.

Rice. 4 Autonomous boiler houses

So what standards, precautions and operational measures need to be taken to ensure that the rooftop boiler room works long and well?

• It is necessary to check the supply and exhaust valves, since thanks to them the boiler room is ventilated.
• It is necessary to install sensors, the design of which controls the process of operation of the gas device and which are triggered directly during the lightest fires. These are necessary to prevent a fire or explosion from occurring. It is advisable that when designing rooftop installations, a function is installed that automatically extinguishes the first signs of a fire.
• It is also necessary to install a gas-insulating flange, which can shut down the entire system at the first sign of a fire.
• On the roofs of multi-storey buildings, it is necessary to install an alarm system that displays and transmits light and sound signals in case of fire.
• The height of the chimney should be much higher than the height of the roof boiler room. The minimum difference is 2 m. Each gas boiler in the house must have a separate chimney, but it is imperative that they be the same height. What the distance between them will be does not matter.
• Roof-top gas units must operate from separate electricity, that is, have a separate branch of the electrical network. The voltage in the house may be different, so you should not take risks with electricity, since due to a failure in the electrical network in the house, problems may arise in the operation of the entire heating system. A diesel generator may be suitable as an autonomous power source.
• This equipment cannot be installed directly above apartments in houses. The presence of a technical floor is a prerequisite for installing a roof boiler room. The floor on which the rooftop gas units will stand must be made of reinforced concrete slabs.
• Do not forget that this heating equipment makes a lot of noise, therefore, in order to be able to install roof-top boiler rooms in multi-storey buildings, it is necessary to meet special requirements in accordance with sound insulation standards in premises.
• The boiler room must have windows and doors that lead directly to the roof. A separate elevator is required, as it will only be used for firefighters. It is also necessary to design a service exit. The boiler room must be illuminated according to the standards (0.03 sq. m/1 m³).
• You should also not forget about the service personnel - there should be a separate safe exit for them during the design.

Rice. 5 Gas equipment on the roof

After designing and installing a gas roof boiler room, it is necessary to look after it, that is, perform maintenance. Maintenance personnel can also handle this. But we also shouldn’t forget about gas service representatives. They must check this equipment at least once a year.

When considering all the disadvantages and advantages of this unit, you will notice that, of course, there are more advantages. Construction companies choose rooftop units for installation in apartment buildings. And all because it is both economical and reasonable, and they work in accordance with all established standards. This is especially convenient when either there is no centralized gas main or it is abandoned during construction.

And so, the main advantages of this equipment:

• Roof units can do without a separate place for themselves. That is, it is not necessary for them to install an additional building. A roof is also suitable for operating gas equipment in a multi-storey building. The water frame or collector may be located away from the design of the roof boiler room (attic, basement).
• Heat loss is very low when these units operate. There is no longer a need to install heating mains, and thanks to this, much less money will be spent on equipment maintenance.
• Costs for connecting to centralized communications are also reduced. And everyone knows that you have to pay a tidy sum for this in our time.
• The design of roof boiler houses has no more requirements. Forced ventilation and installation of chimneys will not be required. SNiP makes it possible for such huge equipment to heat buildings up to 30 m high.
• When designing these equipment in apartment buildings, all standards will be observed and, according to SNiP, the system can be fully automated. The operator will not even be hired for a whole working day, but only for a couple of hours. Thanks to SNiP, the standards for designing rooftop boiler houses will make it possible to install sensors on them that will monitor the temperature outside and turn on the required heating level themselves.
• The good thing is that people will no longer have to adapt to the standards established in the country (there is no heating in the summer). The unit can also operate in the summer if necessary. Who can service a rooftop boiler room? Yes, simple staff who look after her all year round. You won't even need to call specialists. This equipment is easy to use.

This is interesting: No hot water: what to do in this situation and where to call, action plan for 2021
If the equipment is designed according to SNiP, then in no case should it heat additional buildings. Since SNiP states that the power of the equipment should be exactly as much as is needed to design and heat the entire building.

Rice. 6 Based on two boilers

The pros and cons of a roof boiler room are already clear. Now it’s worth talking a little about the disadvantages. The shortcomings in SNiP and design standards are related to the requirements that were in the design of the building itself where the equipment will be installed.

• Introducing new standards in the construction of lifting systems, as well as design according to SNiP and installation of a heating system.
• If the weight of the equipment in the documents is limited, then the rooftop boiler room will not be able to exceed the weight specified in SNiP. And, accordingly, the installation will fail.
• This equipment requires the installation of complex automatic systems. This is also stated in SNiP.
• It is necessary to comply with all standards after designing work with such gas equipment.
• And it would not be superfluous to install fireproof systems in roof boiler rooms, which are made in accordance with all standards and described in SNiP.

Even during design, building codes and SNIP warn that the power of rooftop boiler houses on houses should be exactly enough to heat one building. The SNP also states that equipment is prohibited from exceeding the power required for the consumption of a multi-story building. All standards are specified during design. Calculations and standards according to SNIp must be carried out based on the maximum value of coolant flow.

If it is necessary to use a heating element of a rooftop boiler room on the roof of a house in order to heat adjacent ones, then only in this case it is possible not to adhere to the norms and SNP, but to slightly increase the productivity of the unit. The maximum that can be is 100% of all electricity in the main building.

Rice. 7 Block-modular boiler houses

If suddenly in the future it is planned to design according to all heating standards for adjacent buildings, then a rooftop boiler room, called a block-modular one, for a multi-storey building is simply the best option for design. The block-modular system can be rebuilt to suit any necessary needs.

Installing roof boiler rooms on houses is a very successful business that is becoming more and more popular. Designing this equipment is quite a profitable solution. Although such units on houses appeared in the Russian Federation and other CIS countries relatively recently, they have already managed to gain a good reputation. Due to the fact that the equipment is located on the roof of the house, apartments are heated more smoothly.

January, and with it winter, has passed the halfway mark. But in our climate, houses have to be heated both in spring and autumn, and hot water is generally needed all year round. And I would like to receive heat and hot water at minimal cost. Preferably, reducing losses on heating mains to zero. We talked about individual boilers in the material “How to avoid problems with installing autonomous heating in an apartment?” Now we will discuss the advantages and disadvantages of another option for reconstructing the heating system - rooftop boiler rooms.

A roof boiler room is an autonomous heating source designed to heat and provide hot water supply to residential buildings. As the name suggests, it is erected on the roof of a building, in a specially equipped room. We will not consider stationary roof boiler rooms here. They are constructed at the construction stage of the building, linked with it in terms of design and infrastructure, so local and regional authorities do not have questions regarding them. However, it can be recommended to build stationary rooftop boiler houses if there is a shortage of thermal power in the microdistrict under development.

But block-modular roof boiler rooms are purchased for an already completed building. A block-modular boiler room is manufactured to the required parameters, assembled by the supplier company, transported to the installation and commissioning site in a ready-made form, and is provided with a company guarantee. Its connection to heating networks takes an extremely short time. Another very interesting and useful property of block-modular roof boiler houses: their heating point can be located not only in the boiler room itself, but also in the basement of the consumer building, on the ground floor or on the first floor.

A heating point consists of elements of thermal power plants that ensure the connection of these plants to the heating network, their operability, control of heat consumption modes, conversion, regulation of coolant parameters and distribution of coolant by type of consumer. It transfers hot water to heating systems, to the hot water supply system. It also supplies the ventilation system of a residential building with heat (without which, say, the elementary pipes of garbage chutes would turn into a source of extremely unpleasant odor, and icy winds would whistle along the risers in the bathrooms).

But why is it so important that in the case of a block-modular boiler room it can be placed in the basement of the consumer building, as well as on the ground or first floor? Yes, because this makes it possible to link a block-modular roof boiler room with the existing heating, hot water supply and ventilation systems in the house. Risers, wiring, heating devices - all this will remain in place. Noisy pumps will remain in the basement or basement, driving water upward. At the same time, the fact that a block-modular roof boiler house operating on gas is essentially a huge individual heating boiler, this gives us the opportunity to formulate its advantages.

First of all, it eliminates losses on the heating main, which will reduce current heating costs due to resource savings; eliminates the risk of being left without heat and hot water in the event of a communications breakdown. If the capacity of centralized boiler houses in the microdistrict is not enough to ensure the proper parameters of the coolant in cold weather, it will provide the house with heat in any conditions. These are its advantages, common to individual heating boilers.

The second group of advantages distinguishes it for the better from individual boilers. Well, the most important thing is the ability to preserve the same wiring that was originally laid by the builders of the house. After all, having hung a heating boiler in the kitchen or hallway, we will be forced to lead pipes to it from batteries located throughout the apartment (previously, batteries were powered from vertical risers, and horizontal connections to them ran through attics and basements). So the house switches to individual boilers - each apartment will inevitably undergo significant repairs, which may not be at all in the plans and financial capabilities of the residents). And in the case of a roof boiler room, these unpleasant hassles can be avoided.

The third group of advantages is related to operation. Unlike a gas water heater, which operated in short-term mode, an individual heating boiler burns constantly during the heating period, about seven months in our latitudes. It is, of course, automated. But it’s still good if a large family lives in the apartment and someone is keeping an eye on it so that the younger ones don’t get to the boiler with a set of screwdrivers.

On the other hand, the flexibility of an individual heating boiler is, of course, higher than in the case of a centralized block-modular roof boiler room. You can run it in heating mode and simply on a too cool and wet summer day - in the case of a roof boiler room, you will need a decision from the house council or a similar body.

Economics will give you the answer to this question. First of all, we must keep in mind that switching a house to individual boilers and installing roof-top boiler houses, although it increases living comfort and provides long-term savings on heating and hot water bills, is associated with the need for capital investments. If residents of a house who want to improve the situation with heat supply do not have free funds, then it is better to forget about this option and limit themselves to standard heat-saving measures.

These are not the only costs. A roof boiler room cannot be mounted on floor slabs under which there is a living space - that is, if there is no technical floor, it will have to be built on part of the roof. Under the roof boiler room there must be waterproofing with a layer thickness of at least 100 mm, and reliable drainage. If the building height is higher than 26.5 m (above a standard nine-story building), additional approvals from the fire services will be required. But guidelines can be given approximately as follows.

For houses with 36 apartments or less, it will most likely be cheaper to install individual heating boilers during reconstruction. But with a hundred apartments and above, the economy will lean very strongly towards the roof boiler house (the effect of capacity growth is faster than the price!). In intermediate cases, calculations of various options are necessary - this is the responsible and qualified work of estimators in the construction industry, but we tried to give the most general guidelines and the most general ideas about roof boiler houses.

offers design and installation of boiler rooms on the roof of a multi-storey building!

Our company offers optimal value for money. We work on a turnkey basis, providing a full range of services from project drawing up to commissioning using the most modern energy-saving technologies.

The efficiency of roof boiler houses in an apartment building from Alyansteplo is 94–95%, they pay for themselves in several years. Fill out the questionnaire, call, ask - we will advise you on all issues.

Operation and maintenance of a boiler room on the roof of a house is possible either in a block-modular design, or if its construction was envisaged during the construction of the house: this model is called “built-in”. But in 95% of cases, the roof boiler room of a residential building is a complex of module blocks that are assembled at a factory, delivered to a high-rise building and installed on site.

The construction of a boiler room on the roof of a house is ordered in order to save money and get rid of the “connection” to centralized heating networks. Own boiler room gives residents of the house 30% savings on payments, and also the opportunity to start and end the heating season, based not on a schedule, but on the real air temperature.

Prices for a boiler room on the roof of a multi-storey building start from 5 million rubles. This includes all work, including design, construction and commissioning, and the full cost of the equipment.

Installation of a boiler room on the roof of a house - obtaining a completely autonomous heating station. This has a number of advantages:

1. There is no need to enter into contracts with all sorts of organizations and pay them for maintenance of the boiler room on the roof of the house.
2. Reducing heat loss, which invariably occurs if the boiler room is installed at a distance from the heated object. The heating networks through which the medium is transferred to housing have been updated, which means their efficiency is higher.
3. Payments for heat supply are reduced to a minimum level, also because the rooftop gas boiler room in an apartment building is automated and does not require the constant presence of maintenance personnel.
4. The heating season can begin and end when it is convenient for residents and dictated by common sense. If the cold weather arrived earlier, you can start the rooftop boiler room earlier than the “official” date.
5. Many people ask whether houses with a boiler room on the roof are safe. Our answer is absolutely. All installations undergo multiple testing, and complex signaling and fire-fighting equipment is installed. If you turn to professionals to build a boiler room on the roof of a multi-storey building, any risks are reduced to zero.

Question No. 1 : Is a gas boiler room on the roof of a multi-story building a common property of the building?

Answer : Yes, in accordance with Art. 36 clause 1 of the Housing Code of the Russian Federation. All technical premises belong to the residents of the house. Responsibility for the boiler room lies with the contractor who has been assigned this task by the homeowners. That is why, if a contract for the maintenance of a boiler room on the roof of a house was concluded without the consent of absolutely all residents of the house, it can be challenged in court.

Question No. 2 : Is the roof boiler room a separate floor?

Answer : No, a roof boiler room is a building that is erected on the roof and is not considered an additional floor. A technical room is considered a floor only if it is located in the attic, basement or anywhere between residential floors, and it must be higher than 1.8 m in height.

Question No. 3 : Do I need a license to operate a boiler room on the roof of a multi-story building?

Answer : A license is required for boiler houses that operate on natural gas and serve the population, and at the same time have a hazard class higher than 4. All this is specified in Federal Law 116. A license is also required for boiler houses that are located on the technical floors of a residential building.

Question No. 4 : Is there noise from the boiler room on the roof?

Answer : No higher than 60 dBA in the boiler room itself and 35 dBA in nearby apartments - these are the restrictions dictated by law. Noise should not disturb residents. The most you will hear is a slight hum on the upper floors.

Question No. 5 : Is a rooftop boiler room beneficial for residents?

Answer : The cost of a boiler room on the roof of a multi-storey building is divided among all residents if they are its owners. The service life is over 15 years, after which it is necessary to buy a new boiler. At the same time, residents pay exclusively for electricity and gas, saving on heating on average 30–45%.

offers design, construction, commissioning of a boiler room on the roof of a house, as well as its maintenance. Fill out the questionnaire and we will calculate the price of a boiler room on the roof of the house, and by phone you can get detailed advice on all questions and controversial issues.

An important factor when choosing an apartment in a multi-storey building is the opportunity to save on heating and hot water supply (DHW). There is an opinion that the use of an individual boiler installation significantly reduces utility costs. In this article, we will look at why developers are building autonomous boiler houses near their homes, what this heating system is, and how profitable and safe it is for residents.

Today in Russia, the vast majority of residential buildings, hospitals, kindergartens and administrative buildings use a centralized heat supply system and hot water supply from district heating stations (RTS), combined heat and power plants (CHP) or large boiler houses.

It's no secret that the condition of both the thermal power plants themselves and municipal boiler houses, as well as heating networks, leaves much to be desired, and in some cities is close to catastrophic. Deterioration of heating mains, irrational use of capacity, high energy consumption of outdated equipment, frequent accidents and repairs lead to the fact that consumers are forced to pay for huge heat losses (up to 20% of consumption), depreciation of networks and labor costs for maintenance personnel.

In addition, residents of houses connected to a central heating system depend on the beginning and end of the heating season adopted by the city administration, despite the temperature in the room. This fact forces you to use household heaters in the fall, which leads to an increase in electricity bills, and turn off the radiators in the spring, while continuing to pay bills with extortionate amounts for heating.

Preventative shutdown of hot water in the summer for a period of two weeks is also associated with a large number of facilities connected to one thermal power plant or boiler house, where diagnostic or repair work is being carried out.

Often in apartments on the upper floors the quality of heating and hot water decreases due to the insufficiently high temperature of the water in the pipes.

These disadvantages have led to the fact that developers are increasingly building block (modular) boiler houses to supply heat to residential complexes and even individual apartment buildings.

• Lack of engineering infrastructure for the development site;
• The distance of the object from city heating plants, but the presence of a gas pipeline nearby;
• Capacity shortages and inefficiency of the central heating system;
• Difficulty and/or high cost of coordinating technological connection to existing networks;
• The density of buildings in the central regions interferes with the work on laying heating networks;
• The development area, free of heating mains, allows for the creation of attractive recreation areas, parking spaces, and children's playgrounds.

In addition, the presence of an individual boiler room is presented by developers as an additional advantage for potential clients and allows them to position the property as comfort-class housing.

Block boiler units (BCU) are manufactured at the factory and delivered to the site in already assembled form, the so-called block modules. From the outside, this is a small one-story building that looks like a trailer made of sandwich panels, inside of which the following components and systems are installed:

• hot water boiler, fuel combustion chamber, heat exchangers;
• pumps for circulating water in the system;
• equipment for water treatment and purification;
• flues, chimneys;
• gas equipment (when using gas);
• DHW circuit equipment (if any);
• automatic control and dispatch system, instrumentation.

Based on the type of fuel consumed, gas, solid and liquid fuel are distinguished . Combinations of several fuel types are possible. Gas boiler houses are most widespread due to their high efficiency (up to 95%), and they are also the most environmentally friendly. Solid fuels include coal, firewood, peat, pallets, liquid fuels include fuel oil, diesel fuel, waste oil.

Based on the type of execution, the following modules of boiler plants are distinguished:

• Freestanding They are usually used to supply heat to several buildings and are located at a certain distance from them.

• Attached placed close to the end of the building.

• Roof located on the roof or technical floor of an apartment building.

The latter version is gaining popularity due to its technical and economic advantages, as well as better safety and environmental characteristics.

Savings on utilities compared to apartments of similar size heated from mains are at least 45%, and in some cases reaches 200 - 300%. This effect is the sum of several factors: there is no need to pay for heat loss, the cost of transporting coolant, the cost of maintaining and repairing worn-out main networks, and worker labor.

The calculation of payments for heating and hot water becomes clear and understandable to the consumer. It consists of the physical volumes of resources actually consumed for heat production during the billing period, multiplied by the tariffs corresponding to each resource. The consumption of raw materials, namely gas (or other fuel), cold water and electricity, is confirmed by metering devices. The total cost is distributed among the owners in proportion to the area of ​​apartments and non-residential premises.

An additional advantage of having a home boiler room will be the independence of residents from the heating season schedule and planned hot water outages adopted by the city authorities. The ability to independently quickly control the power of thermal energy production depending on the temperature outside the window allows you to use resources efficiently, saving on utility bills.

In terms of safety, modern autonomous boiler systems are not inferior to centralized systems. From design to commissioning, the process of creating a block boiler house is controlled by supervisory authorities. In addition, automatic safety systems built into the control loop signal threats and block equipment operation in emergency situations. In case of breakdown, a backup boiler and pumps are provided.

In terms of environmental parameters of exhaust gas emissions into the atmosphere, a block boiler house is much safer than a thermal power plant, since the volume of pollution is an order of magnitude smaller, and if it is located on the roof, its dispersion is improved.

The only drawback of an autonomous boiler room for apartment owners is the fact that it belongs to the in-house engineering systems, that is, common property. According to the Housing Code of the Russian Federation, repairs and maintenance of such property are carried out at the expense of the owners of residential and non-residential premises. In practice, these needs are included in the tariff for the maintenance and repair of common property in an apartment building. But since the planned service life of the equipment is designed for 25 years, the considerable cost of its replacement and installation is extended over time and distributed over the area, ultimately remaining profitable for the apartment owner compared to a centralized heating system.

Advantages and disadvantages of a mini-boiler room in an apartment building

Energy resources are becoming more expensive - this is a fact, so the issue of energy conservation has become especially acute lately. This also applies to heating systems of apartment buildings. The cost directly depends on the method of supplying heat to residents, of which there are currently two: centralized and autonomous.

Mini-boiler room in an apartment building and its advantages

If with centralized heating everything is more or less clear, then with autonomous heating it’s not entirely clear. Of course, in addition to the advantages, mini-boiler rooms in apartment buildings also have a number of disadvantages. Let's look at the question one by one.

itself for a residential high-rise building is a separate room

, in which equipment is installed with such power that it is enough to provide heat and hot water to the entire house.

Advantages

1. A shorter “path” from the generator to the consumer. Heat is wasted less along the way, because the distance from the mini-boiler room to the apartment building itself is reduced.
2. The distance is shorter, which means the consumer receives heat faster.
3. Mini-boiler houses are a relatively new thing: they are not as worn out as centralized heating mains, they require fewer resources for maintenance and repair.
4. The cost of such a boiler house is significantly lower precisely because of the previous three points.
5. We can say that the main and main advantage of a mini-boiler room in an apartment building is its proximity to the heated object. In addition, turning the heating on/off can be adjusted to the actual air temperature outside the window, and not to accepted standards.
6. Another “plus” is that there is no need to obtain numerous permits for tapping into centralized heating networks. Often the process is delayed, and residents are not able to move into the purchased property in a timely manner.

Flaws

Let's talk about the disadvantages of such systems.

1. An autonomous mini-boiler room must be placed in a separate room: it is located in close proximity to the facility, sometimes in the form of a stationary building, sometimes in the form of an extension.
2. Cleaning systems need to be thought through. Any boiler room pollutes the environment in one way or another, which is unacceptable for the courtyards of residential buildings. Therefore, it must be equipped with cleaning systems in accordance with rules and regulations. This increases construction costs.
3. High cost associated with the low prevalence of autonomous boiler houses - they have not yet been put into production. Therefore, not all developers can afford them.

However, modern engineering solutions can eliminate some of the shortcomings. For example, an autonomous boiler room can be installed on the roof if the building complies with the standards prescribed in SNiP. It is good if the roof boiler room is included in the project at the construction stage.

Do you need a reliable project for an autonomous mini-boiler room for an apartment building? Fill out the questionnaire at AllianceTeplo - we will help with the design and construction of a boiler house of any type.

Advantages and disadvantages of a mini-boiler room in an apartment building

Read the materials on the topic “​Advantages and disadvantages of a mini-boiler room in an apartment building” provided by.

Advantages and disadvantages of this equipment for heating apartment buildings

When considering all the disadvantages and advantages of this unit, you will notice that, of course, there are more advantages. Construction companies choose rooftop units for installation in apartment buildings. And all because it is both economical and reasonable, and they work in accordance with all established standards. This is especially convenient when either there is no centralized gas main or it is abandoned during construction.

And so, the main advantages of this equipment:

• Roof units can do without a separate place for themselves. That is, it is not necessary for them to install an additional building. A roof is also suitable for operating gas equipment in a multi-storey building. The water frame or collector may be located away from the design of the roof boiler room (attic, basement).
• Heat loss is very low when these units operate. There is no longer a need to install heating mains, and thanks to this, much less money will be spent on equipment maintenance.
• Costs for connecting to centralized communications are also reduced. And everyone knows that you have to pay a tidy sum for this in our time.
• The design of roof boiler houses has no more requirements. Forced ventilation and installation of chimneys will not be required. SNiP makes it possible for such huge equipment to heat buildings up to 30 m high.
• When designing these equipment in apartment buildings, all standards will be observed and, according to SNiP, the system can be fully automated. The operator will not even be hired for a whole working day, but only for a couple of hours. Thanks to SNiP, the standards for designing rooftop boiler houses will make it possible to install sensors on them that will monitor the temperature outside and turn on the required heating level themselves.
• The good thing is that people will no longer have to adapt to the standards established in the country (there is no heating in the summer). The unit can also operate in the summer if necessary. Who can service a rooftop boiler room? Yes, simple staff who look after her all year round. You won't even need to call specialists. This equipment is easy to use.

Features of installation and use

In modern construction of apartment buildings, centralized heating is increasingly being abandoned. The choice of developers falls on rooftop boiler installations for several reasons:

• The construction of a separate building is not required; the boiler room can be located on the roof or in the basement of the house.
• Heat loss is reduced due to the fact that the coolant enters directly into the pipes, and when moving along the heating main, losses can reach up to 20%.
• Costs are also reduced due to the fact that connection, maintenance and contracts with boiler houses are not required.
• Installation on the roof does not require compliance with strict conditions for chimneys and ventilation.
• Human participation is reduced to a minimum, since all systems are fully automated.

The disadvantages include the following points related to the requirements for the building:

• Use in the installation of modern lifting systems and some elements of the roof of the house.
• The weight of the boiler must not exceed that specified in the requirements.
• Installation of complex automation and fire extinguishing systems for gas mini-boiler houses.
• Compliance with all requirements when working with gas equipment.

The requirements for a boiler room on the roof are minimal, especially if its area is less than 27 square meters. Design must take into account the following requirements:

• When using gas equipment in a boiler room, ventilation should be carried out by supply and exhaust valves.
• The fire protection system must start automatically, and fire extinguishing must be done using powder agents.
• In the event of an emergency, the gas supply to the house must be shut off using a gas-insulating flange.
• The warning system should give sound and light signals, as well as issue a message to the remote control about malfunctions or emergency situations.
• The chimney must be installed in accordance with all the requirements for the boiler and gas equipment; according to the standards, it must rise two meters above the roof.
• The rooftop boiler room must have a separate power cable, independent of the house, as well as a generator for emergencies.
• The floor must be insulated and made of reinforced concrete slabs. The location of the boiler room above residential apartments is strictly prohibited; the floor under the boiler room must be reserved for household needs.
• The roof boiler room must provide an emergency exit to the roof surface, as well as a separate elevator.
• Gas equipment must be checked once a year by gas service specialists
• In case of an emergency, a personnel evacuation scheme must be developed.

Of course, boiler room equipment is not cheap, but the number of their owners is constantly growing. The costs associated with the installation are recouped, the installation requirements are justified and feasible, so mini-boiler rooms enjoy deserved respect. For maintenance, it is enough to hire one specialist who will monitor the equipment.

Standards, design and requirements for the operation of boiler houses

Roof boiler rooms for apartment buildings are a modern solution to the problem of designing autonomous heating without connection to a centralized gas main. After all, modern building construction sometimes requires standards that cannot be implemented. Heat loss, thanks to this design of heating for apartment buildings, is low, so installing a rooftop boiler room is even the norm for an economical option.

The popularity of rooftop gas boiler houses is growing every day, since thanks to this heating design, the costs of land allocation will disappear, and there will be no need to design a heating main. And even the temperature can be set more accurately.

What other advantages does designing rooftop boiler houses have? Are there any disadvantages to using it for apartment buildings? Are there safety regulations that must be followed when designing boiler rooms on rooftops?

The requirements and standards for the design and installation of this structure are not significant at all, but still, they exist. Since safety is the main thing in our world, and first of all we need to take care of it.

Rice. 4 Autonomous boiler houses

So what standards, precautions and operational measures need to be taken to ensure that the rooftop boiler room works long and well?

• It is necessary to check the supply and exhaust valves, since thanks to them the boiler room is ventilated.
• It is necessary to install sensors, the design of which controls the process of operation of the gas device and which are triggered directly during the lightest fires. These are necessary to prevent a fire or explosion from occurring. It is advisable that when designing rooftop installations, a function is installed that automatically extinguishes the first signs of a fire.
• It is also necessary to install a gas-insulating flange, which can shut down the entire system at the first sign of a fire.
• On the roofs of multi-storey buildings, it is necessary to install an alarm system that displays and transmits light and sound signals in case of fire.
• The height of the chimney should be much higher than the height of the roof boiler room. The minimum difference is 2 m. Each gas boiler in the house must have a separate chimney, but it is imperative that they be the same height. What the distance between them will be does not matter.
• Roof-top gas units must operate from separate electricity, that is, have a separate branch of the electrical network. The voltage in the house may be different, so you should not take risks with electricity, since due to a failure in the electrical network in the house, problems may arise in the operation of the entire heating system. A diesel generator may be suitable as an autonomous power source.
• This equipment cannot be installed directly above apartments in houses. The presence of a technical floor is a prerequisite for installing a roof boiler room. The floor on which the rooftop gas units will stand must be made of reinforced concrete slabs.
• Do not forget that this heating equipment makes a lot of noise, therefore, in order to be able to install roof-top boiler rooms in multi-storey buildings, it is necessary to meet special requirements in accordance with sound insulation standards in premises.
• The boiler room must have windows and doors that lead directly to the roof. A separate elevator is required, as it will only be used for firefighters. It is also necessary to design a service exit. The boiler room must be illuminated according to the standards (0.03 sq. m/1 m³).
• You should also not forget about the service personnel - there should be a separate safe exit for them during the design.

Rice. 5 Gas equipment on the roof

After designing and installing a gas roof boiler room, it is necessary to look after it, that is, perform maintenance. Maintenance personnel can also handle this. But we also shouldn’t forget about gas service representatives. They must check this equipment at least once a year.
