Technical characteristics of a gas boiler

Let's look at the technical characteristics of the single-circuit boiler Siberia 17:

Russian brands

Floor-standing gas boilers are one of the main areas of work for all Russian manufacturers.

Let's look at some of them:

• Conord. The head office is located in Rostov-on-Don. Gas floor-standing boilers are available in single- and double-circuit versions. A total of 4 series are offered with a power from 8 to 30 kW, the difference between which is the number of circuits and the type of automation;
• Signal. The plant is located in Engels, Saratov region. Currently, two series of floor-standing energy-independent boilers are being manufactured - S-Term and Comfort. The boiler power ranges from 7 to 150 kW, which allows you to choose the appropriate model for any room and conditions. There are single- and double-circuit models;
• Siberia. Products This is a group of floor-standing energy-independent units, presented in three series - Economy, Comfort and Premium. Power range - from 11 to 50 kW. There are single- and double-circuit models;
• ZhMZ. These are gas boilers produced by the Zhukovsky Machine-Building Plant. The range includes single- and double-circuit models of energy-independent floor-standing units with a power from 11 to 68 kW. They are produced in three series - Economy, Universal and Comfort, differing from each other in the type of automation and body shape;
• Lemax. Manufactured in Taganrog. The plant's products include wall-mounted and floor-mounted models with one or two circuits. Three series are produced - Premium, Premier and Prime. The power of the units ranges from 10 to 35 kW.

Most boilers are non-volatile, which is determined by difficult operating conditions, dilapidated power supply networks or a complete lack of connection in remote villages.

This approach is completely justified - in cold weather, a sudden power outage will immediately stop the operation of the heating system, and if the energy supply is not restored in a matter of minutes, defrosting of the pipelines is inevitable.

The only solution is to urgently drain the coolant, but this measure is not always possible.

Therefore, the presence of heating boilers independent of external conditions is a very useful solution for domestic users.

Device

The main design elements of the Siberia 17 gas boiler are an open type burner combined with a steel heat exchanger.

Together they perform the main task - heating the coolant. At the exit from the heat exchanger, the liquid enters a three-way valve, where the colder “return” is mixed into the hot flow to obtain the desired temperature.

The prepared coolant flows by gravity into the heating circuit.

Water moves under the influence of convection currents, moving hot layers up and cold layers down.

Taking this into account, the system must be installed in compliance with the standard slope, ensuring coolant circulation.

If this is not possible, it is necessary to connect an external circulation pump, which will ensure more active flow movement. However, in this case, the energy independence of the boiler ceases.

Smoke removal also occurs naturally, using stove-type drafts. This is an important and crucial point, since weak draft will cause smoke in the premises and the impossibility of operating the boiler. Proper installation and connection of the chimney will help ensure the necessary conditions.

IMPORTANT! The connection and first start-up of the boiler must be carried out by employees of the guarantee organization.

Special features of the automatic system

As mentioned above, all products are automated and have a number of special features:

• The Italian Eurosit system controls the temperature;
• The automated system has a piezoelectric ignition function;
• Automation blocks make it easy to control the system;
• Mechanism of draft and flame control;
• The automatic system optimally consumes gas through the optimal choice of burner function;
• No need to control the process of the combination valve;

All systems are independent of energy, so there is no need to connect to the electrical network, and this is very important for Russia. Constant network failures disable all heating systems

Burner: basic operating functions

The Siberia heating system burner differs from its competitors in its operating features:

• The system is made of stainless steel, so even at low gas pressure there is no burnout.
• The burner is made in Italy.
• The system is made from environmentally friendly materials, so there are no harmful substances in the exhaust gases.
• The burner is very easy to use. You don't need any skill to replace or clean the system.
• At the time of replacing the igniter and the main part of the burner, the system runs on liquid fuel.

A few words about the power that each system has its own. To figure out how much power is required for an area, you can calculate it - take 10 square meters. m per 1 kilowatt. This calculation says that the system will work to its maximum, so add 0.3 to the resulting figure. If you need to warm up a room of 100 sq. m., then you better choose the 11th model Siberia. Moreover, when choosing a heating system, you need to choose design features - material, location, finish. For less insulated rooms, you need to calculate 1.5–2 kW per 10 square meters. m., for warm rooms - 0.5–0.7 kW.

If you want to use the Siberia boiler not only for heating, but also for supplying hot water, then it is better to buy boilers with the letter name K. If you buy the boiler model K, then such a system can provide all the hot water needs for several people. If more than three people will use hot water, then you need to buy a powerful boiler.

How much space is needed to install the boiler?

wall and floor heating systems can be used

The boiler room may not be heated

It is also important to consider that more powerful Siberia models make noise during operation. Some manufacturers produce powerful floor systems with excellent heat and sound insulation, which are installed outside the boiler room - in the hallway or kitchen. Additional details of the system are:

Additional details of the system are:

• Cranes;
• Expansion tank.

How to save on heating?

Without the slightest loss in comfort, you can reduce fuel costs by 10%. Especially if you have a private house and you are going to carry out major renovations. The initial costs can be recouped even with basic tariffs, and the price of fuel will rise. Your invested money will pay off even faster.

The very first thing you can do is reduce the heat loss of the building. This is a whole range of works, installation of doors and windows, insulation of walls

After all the work has been carried out, thermal monitoring must be performed: it is important to check that heat does not penetrate through the cracks. There are special companies that check losses using thermal imagers. And the owner of a private house can purchase a remote thermometer

It is also very important to choose a boiler based on power and positive reviews. The more square meters you need to heat, the more carefully you need to pay attention to heat calculations

The Siberia brand is one of the best on the heating systems market. Systems with high power are very expensive, but consumer reviews are still positive. They evaluate the quality of use and technical properties of heating devices.

Siberia boilers review and reviews

The Russian market of heating systems and water heaters gained its popularity among consumers mainly thanks to. The Rostov-based manufacturer of gas boilers and heating appliances, producing products under the Siberia brand, has been operating in the domestic market for several years.

The production technology developed over the years, which in many respects surpasses its competitors, contributes to an increasing demand for heating boilers. Despite the fact that Siberia boilers are a relatively young brand (produced since 2006), it has already managed to gain a leading position in sales.

Siberia are gas-powered, non-volatile boilers that are equipped with a reliable automation system. Despite the fact that the EUROSIT system is produced in Italy, it is fully suitable for use in our country. It is designed in such a way that the boiler operates even with reduced water and gas pressure; in addition, EUROSIT does not require connection to the electrical network. Rostov-made boilers are used both for heating residential buildings and for industrial and commercial facilities.

Siberia heating devices are a new generation of products, which in design, quality of work and technological characteristics are not inferior to foreign analogues. And in comparison with competitors, Siberia products have a number of advantages.

Specifications

1. Heat exchanger tank - is highly durable and reliable thanks to the use of quality materials and an automatic welding process. The steel heat exchanger provides more efficient heating of the coolant. There are models with cast iron heat exchangers, which ensure a device service life of more than 25 years.
2. Siberia double-circuit boilers supply the heating system with hot water thanks to a flow-through copper circuit.
3. Siberia boilers can be used in all water supply systems (with natural and forced water circulation).
4. All Siberia boilers are manufactured using a layer of thermal insulation, which helps prevent burns and injuries.
5. The device is assembled from high quality materials.
6. All Siberia boilers are easy to use, maintain and install.

Automation

As mentioned above, the automation system has a number of features:

• the Italian Eurosit system maintains the temperature as accurately as possible;
• the automation has a piezoelectric ignition system;
• convenient location of automation units makes the device easy to operate;
• the system has a draft sensor and flame control;
• automation promotes optimal gas consumption by selecting the burner operating mode;
• there is no need to adjust the operation of the combination valve;
• The boilers are non-volatile, so there is no need to connect to the electrical network, which is especially important for Russia. Unfortunately, constant power outages damage heating systems and foreign analogues, unlike Siberia boilers, which are adapted to Russian characteristics and harsh climate.

Burner

The burner of Siberia gas boilers also differs from competitors’ products:

1. The gas burner device is made of stainless steel, so it completely eliminates burnout even at low gas pressure.
2. The burner of Siberia Worgas boilers is manufactured in Italy, which speaks for itself.
3. An environmentally friendly gas burner device does not contain harmful substances such as nitrogen oxide and carbon oxide in the exhaust gases.
4. Operation of the burner is simple; cleaning or replacing the device does not require much knowledge or skills.
5. When replacing the igniter and the main part of the burner, the device can operate on bottled liquefied gas.

Reviews of Siberia boilers

I purchased a Siberia brand boiler several years ago. It works properly, heats quickly, is very economical, the only thing is that the boiler took a very long time to light up. The igniter began to work with difficulty, we had to wait for several hours. As the neighbors suggested, the problem is in the chimney - a large backdraft. I punched a hole into the street to provide more air flow. There is no more problem.

Sergey

This is not the first winter I have been using the Siberia boiler, everything is fine. But one day, when I increased the gas supply, the burner went out and the temperature maintenance sensor stopped working. I cleaned the gas filter and everything worked. I heard that Siberia has this problem, so I advise you to check everything yourself first, and not run to the gas service.

Alexander

I installed a Siberia boiler, but during the work there was something noisy in the pipes. I contacted a specialist and they said that everything was fine, there was just air in the heating pipes. Anyone who has had the same thing should not worry.

Rules for using the equipment

In order for your boiler to last as long as possible, you should handle the equipment without violating the operating rules:

Do not turn on a boiler with a broken burner or a clogged chimney; the case requires grounding; if you use antifreeze as a coolant, then you need to buy a product that has a certificate; It is important that there is no ethylene glycol in the antifreeze. You can read about antifreeze for heating systems here. The water temperature should not exceed 95°C; if you install the device near a wall that is covered with a fire-hazardous material, then the gasket should be made of steel or asbestos; You can turn on the device only after the system is filled with water/antifreeze; Every year it is necessary to clean the chimney and filters. https://youtube.com/watch?v=PZbu_IE6RM8

Brief overview of models

Of particular interest are Siberia gas floor-standing boilers with steel heat exchangers. This line is the best-selling and most practical, as confirmed by numerous certificates. In total, Siberia products are represented by 19 models:

• Floor and wall (11).
• Boilers with cast iron heat exchangers (4).
• Water heaters (4).

Technical equipment and design features

The heat exchanger of a gas boiler is made of high-carbon heat-resistant steel or thin-walled cast iron. A distinctive feature is the developed area of ​​this design: water is heated not only by burning fuel, but also by using the thermal energy of combustion products. Siberia heaters are equipped with a gas atmospheric burner made of high-alloy steel, which is known for its strength and heat resistance. There are varieties with open and closed fireboxes; almost all boilers have a piezoelectric ignition system (the exception is those marked with the letter “i”).

The protective automation is designed as a separate unit, including:

• Magnetic valve.
• Built-in filter for cleaning gas fuel.
• Modulating thermostat for quick on/off function.
• Re-ignition blocking.
• Stabilizer for monitoring changes in pressure in the fuel supply line.

To insulate individual elements inside the body of a gas boiler, basalt fiber gaskets are used; the outer coating is made primarily of powder enamel; some cast iron varieties have a metal shell (stainless steel). In this way, the manufacturer protects the consumer from burns and injuries. Feedback from owners about the design and control panel is more than positive; it is widely believed that in terms of aesthetics and user-friendliness of the interface, Siberia is in no way inferior to its foreign counterparts.

The advantage of some models is the built-in function of replacing natural gas with liquefied gas; it protects the owner of a heated room in case of emergency breaks or allows you to install the boiler in places without a constant gas supply. Siberia is used not only as the main source of heat, but also for hot water supply. In case of such a need, you should buy devices marked “K”, indicating the presence of a second circuit. In DHW mode, the boiler provides from 3.8 to 12 liters per minute when heated to 25 °C and about 9 when the water temperature rises to 40.

Hot water supply

In cases where you plan to use a floor-standing boiler not only to heat rooms, but also to obtain hot water for household needs, you should take a closer look at models marked “K”. Such models have two heating circuits, which means they are able to simultaneously heat the room and provide it with hot water.

When choosing the right floor-standing gas boiler Siberia (reviews about the quality of the water supply depend on correctly carried out calculations), you should again refer to the boiler power indicators.

It should be noted that for a family of three, the boiler should be able to prepare hot water at a rate of 4 liters per minute. Among the Siberia models, the 11K boiler satisfies this requirement.

Siberia or Lemax: which is better

Floor-standing gas boilers have a similar, slightly more complex design, but similar automation and burners. The efficiency of almost the entire Lemax model range is also 90%, but gas consumption is on average 10% higher. For example, Lemax Premium-16 kW has a maximum gas consumption of 1.9 m 3 / hour. Lemax boilers are quieter, and even steel models are designed to operate in a circuit with a pressure of up to 3 bar. However, their cost is 10-20% more expensive.

Siberia is more reliable, more economical, simpler and cheaper. But it is deprived of the above-described advantages inherent in the Lemax model range. In general, both manufacturers are worthy of attention and it is not for nothing that they are sales leaders among domestic manufacturers of gas boilers.

Advantages and disadvantages of boilers

Independence from power supply is one of the advantages of Siberia boilers

The advantages of Siberia boilers include:

• reliable and time-tested design and clear operating principle;
• the cost is quite acceptable for the average user;
• compliance of technical characteristics with the requirements of regulatory documents;
• independence from power supply;
• the presence in the range of combinations of not only single-circuit, but also double-circuit models.

A description of the advantages of Siberia boilers will be incomplete without mentioning the compactness and perfect design of the wall and floor samples offered by the company. In addition, users are attracted by the presence in the model range of products equipped with an almost “eternal” cast iron heat exchanger.

The disadvantages of the design and operation of some models include the following points noted by the owners in their reviews:

• noise of ignition and subsequent operation of the gas igniter;
• the need for maintenance of boiler equipment (regular cleaning of the burner, igniter and heat exchanger);
• not very high productivity for FGP in dual-circuit systems.

What to look for when choosing?

Before purchasing a dual-circuit model, you should pay attention to five important indicators:

Combustion chamber type

There are devices with an open and closed combustion chamber. Appliances with an open chamber take air from the room, and combustion products are discharged through the chimney. For safety reasons, such a chimney must be at least 4 m in height. Since this consumes oxygen from the room, ventilation in such a house must be well organized.

With closed combustion, air is taken from the street, and combustion products are discharged outside at this moment. Thus, the oxygen in the room does not burn and the overall atmosphere is much more favorable. Models with a closed chamber are suitable for those who have poor ventilation in their home. They can also be installed in the kitchen or bathroom. Devices with a closed combustion chamber are the only possible option for apartment buildings.

Boiler type

There are classic (convection) and condensation devices.

Classic wall-mounted gas boilers with two circuits, the 2020 rating of which will be given below, generate heat only by burning gas. On average, their efficiency ranges from 85 to 95%.

Condensing appliances generate additional heat by condensing water vapor that is produced naturally during the combustion process. Thanks to this, the boiler efficiency increases and can range from 100 to 110%. Taking this into account, the condensing model can reduce gas consumption by 10 - 15%. This savings will be especially noticeable when using heated floors. If you really want to save on heating and water heating, then take a condensing model. Such models will definitely be included in our rating of wall-mounted double-circuit gas boilers in terms of reliability.

Heat exchanger material

The heat exchanger of the device can be made of the following materials:

• Cast iron. Used in the cheapest models. It generates heat quite well, but the efficiency usually does not exceed 90%. Boilers with cast iron heat exchangers are heavier and bulkier, which complicates their installation.
• Stainless steel. Suitable for budget and middle class. Stainless steel is quite durable and can be easily repaired if necessary. However, heat transfer is less than that of copper.
• Copper. Copper heat exchangers are installed in mid- and expensive-class models. They are durable and dissipate heat well.

If you want to take a classic model and are going to install it yourself, take it with a stainless heat exchanger. For underfloor heating and hot water supply, we recommend choosing a condensing type device with a copper heat exchanger.

Boiler power

On average, 1 kW of device power can heat about 8 m2 of area. Divide the total area you need to heat by 8 and get the required power. Add 1 kW for water heating. If you want to more accurately calculate the power of the device, use the formula that we provided for single-circuit boilers.

Availability of built-in boiler

A separate type of double-circuit boilers can be additionally equipped with a boiler for heating and, most importantly, storing water. Sometimes it is very convenient to have such a boiler, since if there is a strong drop in pressure in the pipeline, the boiler may simply not heat the water, but the water in the boiler will always be hot. Purchasing a model with a built-in boiler makes sense only in cases where there is a frequent drop in pressure in the city water supply. Otherwise, it's a waste of money.

The most common problems and breakdowns

It is clear that there is no perfect equipment and it breaks down or does not work as it should. In most cases there are specific reasons for this. Based on the operating experience of Siberia boilers, we can identify several characteristic problems that owners often encounter:

• Low heating of water for domestic hot water supply by Siberia double-circuit floor-standing boilers. There's nothing you can do about it - it's not their strong point. If you look at the technical specifications, the maximum hot water flow is very small. And this is at normal gas pressure. If the pressure is low (which usually happens in cold weather), then the water will be slightly warm.
• The water at the boiler outlet does not heat up to the stated 90°C (if you turn the regulator even to the very last, 7th position). There are several possible reasons. The first is low gas pressure. When the pressure drops below 130 mm. water the column's power decreases proportionally. When you call the gas service (they are responsible for the nominal pressure), ask them to clean the inlet filter. If it is clogged, the pressure will be low. The second possible reason is a burner clogged with soot and dust. It needs to be cleaned once a year. If this is not done, the efficiency decreases and the Siberia boiler heats worse.
• The pilot burner does not ignite the working burner. Again, there may be several reasons. And the first is low gas pressure in the pipe. But this time it is below 50mm. water pillar At this pressure the boiler does not start. The second reason is a clogged gas valve. The third is a smoked burner. In all cases, we clean the valve and/or burner. Fourth, the thermocouple sensor is located too far away (you can see it visually, if it doesn’t reach the flame, that’s the reason). In this case, you need to loosen the thermocouple mounting nut and move the contacts a little closer. Fifth - weak traction.
• After a summer of inactivity, it is difficult to start the boiler. During downtime, air collects in the gas supply pipe. Until it is “corroded”, it will not be possible to light the boiler. When igniting for the first time, open the window/vent and monitor your health. Take a break between launch trials. During this time, the burner will be ventilated and the Siberia floor-standing gas boiler will start up faster.

As you can see, there are a lot of problems, but most of them are related to the peculiarities of the work of public utilities in our country. Of course, there are reasons in the equipment. But this is a small part of the total number of cases of non-working equipment. In order for the Siberia floor-standing gas boiler to work without problems, it is worth fulfilling all installation requirements and carrying out regular maintenance.

Possible malfunctions of the Siberia boiler and methods for eliminating them

1. If the panel fuse is damaged, it can be replaced.
2. If the room thermostat is set to a lower temperature or the timer is off, you need to adjust the settings.
3. If the gas does not correspond to the specified data, then you need to contact the service center.
4. The gas valve has been found to be defective and needs to be replaced.
5. If the fan of the boiler with a closed gas chamber has stopped and there is power, then it needs to be replaced.
6. The relay setting is out of order - replace it.
7. Tubes are clogged - clean.
8. Broken ignition electrode - replace.
9. The electrode is installed incorrectly - install correctly.
10. Defective ignition device - replace the device with the help of a specialist.
11. Air in the pipes is blocking the burner - ignite several times in a row.
12. Incorrect polarity of the power line can also block the burner - check the polarity and, if necessary, connect correctly.
13. The monitoring electrode is not connected - contact service.
14. If the flame is of an unusual color or height, then you need to adjust the gas supply.

Main components of the Siberia gas boiler

Criteria for choosing a gas boiler

One of the most important characteristics of a gas boiler is thermal power. This value shows the maximum amount of heat that the device can produce when burning blue fuel. The power is selected taking into account the heated area. It is generally accepted that for heating 10 square meters. m requires 1 kW of thermal energy. However, this ratio is ideal, and since gas boilers have an efficiency of 90-95%, you should choose a more powerful unit (about 10-15% of the calculated value).

Floor-standing gas boilers can be single- or double-circuit. If the house has a source of hot water or it is not needed every day, then you should give preference to single-circuit models. Otherwise, it is more profitable to take a dual-circuit device. Many modern models must be connected not only to the gas mains, but also to a single-phase electrical network. In those populated areas where power outages often occur, it is better to install non-volatile models. The only inconvenience will be manual ignition of the burner, and the connection is made to an open-type heating system with good natural coolant circulation. The main part of the boiler that experiences extreme loads during operation is the heat exchanger. The most durable products are made of cast iron. Steel analogues are susceptible to corrosion, and deformation and cracking of the walls often occur. But boilers with steel heat exchangers attract buyers due to their affordability. Some homeowners are interested in universal gas boilers that can operate on both natural and liquefied blue fuel

When purchasing a gas boiler, you should pay attention to gas consumption. Low-power models do not always outperform more efficient competitors in terms of efficiency.

It should also be noted that the consumption of natural gas is indicated in cubic meters per hour, and liquefied gas in kilograms per hour. Depending on the control method, there are gas boilers with a mechanical or electronic unit. Mechanics are cheaper and easier to maintain, and the presence of automation allows you to set the desired air temperature in the rooms and no longer interfere with the operation of the boiler.

Features of Siberia boilers

All Siberia boilers are non-volatile. This is the main feature of these boilers.

Energy independence means that the operation of these boilers is completely independent of the presence of electricity: ignition in this system is carried out by a piezoelectric element (an electric spark occurs when pressure is applied to the material); There is no fan installed in the chimneys of this heating system: there is also no pump for forced pumping of water through the circuit; natural circulation occurs in the circuit.

In order for natural circulation, boilers must be installed below, so most models of this brand are floor-standing.

In addition to the indicated main feature of these boilers, it is worth adding that they cope well with uneven supply of gas and water; also, some models are capable of operating not only on natural gas, but also on liquefied gas, which makes the entire system more independent of the eccentricities of the Russian economy.

In addition, following the fashion of the times, some elements (burner and tracking system) have foreign roots, which indicates their increased reliability. The boilers are coated with powder enamel, which makes them strong and durable. Any of the devices in this series is decorative and compact in size.

It is also important that all devices of this brand are easily disassembled and repaired. Modern models of the Siberia series are capable of heating not only apartments and houses, but also industrial premises, the area of ​​which is quite significant. Efficiency is about 90%

• unpretentious, economical boiler. Fuel consumption is noticeably lower than that of analogues from other manufacturers;
• ease of management and maintenance;
• relatively low price.

Flaws:

• the declared indicators cannot always be achieved, the boiler power is sometimes not enough;
• Difficult and inconvenient ignition.

Non-volatile boilers are optimal in Russian conditions. In cold weather it is too dangerous to remain without heating, so the independence of boilers is highly valued by users.

Features of Siberia boilers

Siberia gas boilers have the following characteristics:

1. The device has efficiency = 90%.
2. Availability of heat-resistant high-alloy steel burner Polidoro.
3. The flame size is adjusted automatically.
4. The firebox can be open or closed.
5. Power, depending on the model, varies from 11 to 50 kW.
6. The burner can be converted to operate on liquefied gas.

Owners of Siberia floor-standing gas boilers note the heating efficiency even in a house with several floors, and the rapid heating of water in the presence of several intake points. The units are divided into three main modifications:

• single-circuit AOGV with a cast iron heat exchanger;
• double-circuit AKGV with steel circuit;
• KCHGO of increased power from 16 to 50 kW with a cast iron heat exchanger.

The power of floor-standing devices AOGV and AKGV ranges from 11 to 35 kW. For heating a one-story house with an area of ​​up to 100 m², the AOGV11 unit with a power of 11.6 kW is suitable. And for heating rooms measuring 230-400 m², only models with an indicator of 23 kW are suitable.

Note! The maximum coolant temperature in the circuit can be 90°C. The letter “K” denotes units with two circuits. The production of hot water supply in them is ensured by a flow-through copper heat exchanger

Double-circuit gas boilers can heat water up to 65°C. They can be used in systems with forced or natural water supply

Hot water production depends on the boiler power: for 11 K - 3.8 l/min, for 17 K - 5.5 l/min, 23 K - 7 l/min, 29 K - 8 l/min.

KCHGO models have only one circuit, an atmospheric burner, and are capable of heating an area of ​​up to 600 m².

Gas consumption

Floor-standing gas boilers Siberia 11 and 17 can be converted to use bottled fuel, while all others can only operate on mains gas.

The units of the presented company are among the most economical and consume 1.18 - 3.75 m3/h depending on power. When operating on liquefied fuel, up to 1.21 m3/h is consumed.

Note! Siberia gas boilers are able to operate even at low gas pressure

Automation

The correct operation of floor-standing gas boilers is controlled by the Eurosit automation system. It was made in Italy, but fully adapted to Russian conditions. The Eurosit system includes:

• piezo ignition;
• precise temperature maintenance;
• the presence of flame sensors and traction control;
• convenient and simple control panel.

Siberia floor-standing gas boilers are one of the most popular domestically produced units. Consumers are attracted by their low cost (14,000 - 35,000 rubles) in comparison with foreign analogues (from 60,000 rubles), gas and electricity savings. They will be indispensable in regions where there are frequent power outages and low gas pressure in the mains. You can learn about the installation of Siberia floor-standing boilers from the video.

What series and models of the company exist?

There are three model lines:

• AOGV. Single-circuit floor models used only for space heating. They have 5 models with power from 11 to 35 kW. They are simply marked Siberia 11, Siberia 17, etc.
• AKGV. Double-circuit units providing heating and hot water supply. They have the same power models, the marking contains the letter “K” (combined) - Siberia 17K, Siberia 23K, etc.

NOTE!

Both groups (AOGV and AKGV) are equipped with a primary heat exchanger made of stainless steel. Double-circuit ones have a secondary plate heat exchanger for heating hot water.

• KCHGO. Increased power models with cast iron heat exchanger. The power range is between 16-50 kW.

The power of the boiler determines the area that it is capable of heating: 11 kW - 110 m2, 35 kW - 350 m2, etc.

The lineup

Floor-standing gas boiler Siberia 11K

The classic floor-standing boiler Siberia AOGV is part of a range of products that are compact in size and have a very reasonable price. Their range was expanded by releasing models with varying technical parameters (declared power and performance). Among them, economical models stand out, produced in versions of 11, 17 and 23 kW, as well as with higher power, reaching 35 kW. This series also includes dual-circuit models. The letter “K” (“Siberia 11K”) is usually added to the name of the latter. At the same time, they cost only 10-15% more than single-circuit models.

Experience in operating medium-power units (17 and 23 kW) has proven that they are among the most successful and reliable models produced by domestic manufacturers. However, they also have all the disadvantages already discussed, including sensitivity to contamination of components and coolant, as well as noisy ignition. Since the maximum permissible operating pressure of these models is no more than 1 bar, it is not recommended to use them in closed systems (in them the indicated indicator reaches 1.5-2 bars). The cost of boilers in this series varies between 19.8-26.0 thousand rubles.

KCHGO series

Gas floor boiler 16 Siberia KCHGO

One of the best examples presented on the market by the Siberia production association are boilers for heating a private home from the KCHGO series. Their main difference from previous models is as follows:

• large dimensions and weight of the product due to the cast iron heat exchanger;
• long service life (up to 30 years);
• higher permissible coolant pressure, which averages 3 bar;
• a wide selection of versions differing in declared power (16, 25, 40, and 50 kW).

Top Line Series

Wall-mounted gas boiler Siberia Top Line 24C

This series is represented by mounted models, in which all the necessary modules are already built-in: a safety group, an expansion tank, and a circulation pump. Their difference from other products is the presence of a modulating burner, which allows reducing gas consumption to 2.65 m3/hour (with an operating power of 24 kW). The heat exchanger of these models is made of copper, which has better thermal conductivity and is more resistant to corrosion than steel.

In double-circuit boilers, a dual circuit of coolant circulation is used, which significantly complicates the possibility of washing or cleaning it. Therefore, only soft and well-purified water is used as a coolant.

In addition to everything listed, these samples provide protection against overheating and freezing, as well as the ability to connect an external thermostat. The only drawback of these models is the difficulty of purchasing, since they are still rarely found in the assortment of online stores. Due to the lack of other versions, only single-circuit Top Line 24 kW is currently available. Their cost varies from 21,500-27,000 rubles.

Model range of Siberia boilers

Gas equipment produced at the enterprise is represented by three series:

• economy
• comfort
• premium

The production of devices belonging to the first of them was mastered in 2005.
It has four Econom Siberia models in its lineup. They differ in power, which is 11.6 and 17.4 kW, and in the number of circuits; models with the letter K have two. The boilers of this series use burners made in Italy, which made it possible to achieve high quality products. The protection was taken under control by Eurosite (Italy) and Honeywell (USA) automation. The advantages of the equipment include the ability to operate on liquefied gas after reconfiguring the equipment, which makes them indispensable in emergency situations in the gas pipeline network. To give the equipment a modern appearance, all cases are painted with special enamels, which form a protective layer that protects the surface of the boiler from scratches and chips.

The comfort series consists of five Comfort Siberia models:

• 23
• 29
• 35
• 40
• 50

Siberia floor-standing gas boilers are used for heating large houses. The collection includes samples with one and two circuits, the latter capable of heating up to 8 liters of water per minute. They have a circulation pump in their design that prevents overheating of the heat exchanger.

The third series of boilers - the Premium TopLine-24 models - are for small rooms and have a second circuit for preparing hot water.

Their main feature is the electronic ignition of the burner with ionization flame control, as well as the presence of exhaust gas control and anti-scale protection functions. Boilers of this brand have an efficiency of 90%.
