Which Russian-made gas boilers should you choose for heating - a review of domestic manufacturers

The best gas boilers for heating areas up to 200-300 sq. m.

As the heated space increases, the problem of saving gas fuel becomes more acute.
To ensure low heating costs, when choosing a boiler, you need to pay attention not only to power, but also to its efficiency. For some models from this rating (they work on the condensation principle) it exceeds 100%

Such data were obtained in accordance with domestic calculation standards, and according to the European methodology, their real efficiency is approximately 95%. Accordingly, in order to get an idea of ​​the real efficiency of simple floor-standing gas boilers, the calculated efficiency value should be reduced by 12-15%.

What types of gas boilers are there?

A boiler is, first and foremost, a functional device, and it is not cheap to purchase. But the most important thing is that with the right choice, it is the boiler that can significantly reduce the costs of its owner, and the number of repairs of the heating system, the frequency of visits to service centers and the participation of the residents of the house in the maintenance of heating equipment depend solely on the successful choice.

Will the boiler start at the beginning of the season, will it have to be lit manually and how often, will it provide the maximum possible savings on heating, will the boiler lead to air pollution and the room in which it is installed, will it lose its appearance over time and how long will it last - all this depends on the correct choice of boiler suitable for a particular room. Moreover, you can avoid all of the above inconveniences without overpaying, but simply by competently choosing heating equipment.

When choosing a gas boiler, you usually pay attention to the following characteristics:

1. Performance. The amount of heat generated over a certain time. This indicator affects the ability of the boiler to serve a certain area.
2. Economical. This is the boiler efficiency factor, which is affected by the percentage of heat dissipated around the heating device.
3. Material of manufacture and quality of components. Affects the reliability of the boiler.
4. Energy independence. The need to connect the device to the mains.
5. Availability of additional functions. Some are responsible for the optimal operation of the boiler, some are responsible for the safety of its use.

Boilers are classified according to installation method, functionality and method of exhaust gas removal. According to the method of installation, boilers are wall-mounted and floor-mounted, according to the type of functionality they are single- and double-circuit, and according to the method of gas removal - with a closed and open combustion chamber.

Floor-standing boilers are in greatest demand: they allow heating a large area, are reliable and have a wide power range - 11–68 kW.

Russian manufacturers have learned to produce floor-standing boilers adapted to our operating conditions and capable of competing with imported models, therefore, by purchasing a Russian-made floor-standing gas boiler, you can reduce start-up costs and get a completely reliable heating device that is in no way inferior to foreign ones.

Double-circuit or single-circuit?

Single-circuit boilers differ from double-circuit boilers in their purpose: the former only provide heating, the latter are respectively used for both heating and water heating. The water heating unit built into a double-circuit boiler can be flow-through or storage type. And if you need help choosing a boiler for a private home, our article “Which boiler is best to choose for a private home” will come in handy.

The storage unit can hold up to two hundred liters of water. Thus, if you buy a double-circuit floor-standing gas boiler made in Russia, two problems are solved at once - heating and hot water supply. Sometimes it is advisable to purchase a boiler for a single-circuit boiler, then it will work on the double-circuit principle. However, double-circuit boilers are much more compact, so they are better suited for rooms with limited space. But they have a requirement: the flow of incoming water must be under high pressure. In addition, they are not suitable in cases where the bathroom is located at a great distance from the boiler itself.

Closed and open combustion chamber

As for the type of combustion chamber, an open chamber uses room air and exhausts exhaust gas through a chimney; a closed chamber (turbo) contains fans that take air from outside and send combustion products there. Boilers with an open combustion type operate on the principle of gas burners, they heat up themselves, warm up the air around them (hence the lower efficiency), and require some distance from flammable objects. Turbo models are considered more economical and safe.

Among domestic models you can find all the listed types of floor-standing boilers, choosing according to the necessary parameters. Experts believe that modern Russian-made floor-standing gas boilers, even if they do not have highly competitive technical and operational characteristics, perform their main functions properly.

Nuances of maintenance and connection

Now, as before, installing a gas heating boiler is not an easy task. To install such equipment you will need:

• coordinate actions with Gostekhnadzor;
• draw up a boiler connection project;
• prepare the room, connect the chimney, ensure the main gas supply to the boiler.

A number of norms and rules have been developed that will have to be followed during installation:

• you will need a ventilated room for installing the boiler, with access to the street;
• the area of ​​the room must be at least 100 m²;
• It is mandatory to install an automatic system that is responsible for gas leaks.

Gas boilers of the old type were connected to chimneys at least 5 m long, only with natural draft. These requirements were mandatory and contributed to minimal formation of condensation - the main drawback of retro devices.

Now coaxial chimneys and circulation pumps are used, so it is possible to provide forced draft and install the chimney through a wall or into a ventilation shaft, which makes installation easier and makes the chimney connection area neater. The photo shows the correct installation of the boiler.

Review of the most popular models

Among Russian manufacturers there are leaders who are actively introducing new technologies and offering a wide range of products. We present an overview of heating boiler models that enjoy the greatest confidence among consumers.

"Rostovgazapparat"

This manufacturer offers a wide range of heating equipment. Consumers can choose floor-mounted or wall-mounted units, depending on the required power, and also select a single-circuit (with one heat exchanger designed to ensure the operation of the heating system) or a double-circuit version of the heating unit. Moreover, most of the boilers produced by the company are equipped with modern and very convenient automation systems.

One of the most popular models offered is the Siberia boiler. All units of this brand are floor-standing, so their installation requires an isolated room.

Boilers are produced in a fairly wide range of power, so you can choose a single-circuit unit for heating a small house or a spacious cottage, as well as a model with two circuits that allows you to use hot water.

Siberia boilers are one of the most popular models of the manufacturer. The single-circuit version of the boiler is popular; these are reliable floor-mounted installations with a cast iron heat exchanger. But if you need to not only heat the house, but also provide it with hot water, you should choose a dual-circuit unit. Models with two circuits can have both cast iron and steel heat exchangers.

Sibiriya boilers are completely energy-independent; even for ignition, a piezoelectric element is used, not electronics. This boiler option is an ideal choice for areas where power supply is unstable.

Boilers of this brand are designed to operate on natural gas, and the equipment is insensitive to a decrease in supply pressure.

Advice! Some models of Sibiriya units are suitable for operation on liquefied gas after replacing the burner.

The boiler automation provides:

• uniform gas supply even when pressure decreases;
• shutting down the unit in case of overheating or flame failure.

The boilers are easy to operate and maintain, the equipment is affordable and has a presentable appearance, so they are in steady demand.

ZhMZ

The Zhukovsky mechanical plant has been producing gas equipment for autonomous heating systems for several decades. During this time, the products managed to win great consumer trust. The plant offers reliable floor-standing units; you can choose either single-circuit or double-circuit options. All products can be divided into three classes:

• Economy These models use domestic automation - simple and reliable. This option is non-volatile.
• Station wagon. The models are equipped with imported automatic systems, creating great convenience during operation.
• Comfort. The boilers are equipped with a perfect automatic system that fully controls the operation without requiring user intervention.

Concord

Domestic heating units of the Concord brand are produced in a wide range of capacities - from 8 to 30 kW. You can choose a double or single circuit option.

Advice! A single-circuit boiler of the Concord brand is worth purchasing if you need to provide heating for rooms with an area of ​​30-300 square meters. If you need to obtain hot water, you should purchase a model with two circuits and a power of at least 20 kW.

All models of this brand provide a chimney with natural draft. For control, different types of automation are used, both Russian and imported sensors are used.

One of the most popular models is the Don single-circuit boiler. This is a universal model; it can run on both gas and solid fuel.

Advice! If there is no gas pipeline in the village yet, but it is planned to be installed in the near future, then purchasing a Don boiler is a profitable solution. The boiler can be operated on solid fuel, and after supplying gas and replacing the burner - on gas.

Gas apparatus

The production plant is located in St. Petersburg. One of the most famous is the Neva-Lux wall model. This can be a two- or single-circuit unit with different power ratings.

Neva-Lux wall-mounted units are equipped with a modern automation system, and steel heat exchangers are used. Wall-mounted boilers are installed complete with a coaxial chimney; air is forced into the combustion chamber by a fan. Automation allows you to program the operation of the heating unit for 7 days, and also prevents the formation of various emergency situations.

JSC Borinskoye

Wall-mounted heating units produced by Borinskoe JSC are very popular. Compact wall-mounted boilers are an excellent choice for a summer house or small house. You can choose a single-circuit option that will ensure the heating of the house. The company's range also includes a wall-mounted version with an additional copper coil for supplying hot water.

The boilers are equipped with automation systems that allow complete automation of work processes. Among the most popular models of the brand:

• Ishma. Reliable units with automatic protection against emergency situations.
• KOV. Powerful, reliable boilers that are used not only in residential buildings, but also in enterprises.
• AKGV. This is an ideal model for cottages and small houses.

So, Russian-made gas boilers are presented in a fairly wide range. The consumer can choose a floor-mounted or wall-mounted option depending on the required power of the equipment. In addition, you can choose a single-circuit boiler or take a model with two heat exchangers to provide the house not only with heat, but also with hot water. Modern models are equipped with reliable and convenient automation.

The right choice - double-circuit or single-circuit?

As you know, according to the number of circuits, gas boilers are usually divided into single-circuit and double-circuit. Which one is better? The correct choice depends on the main purpose of the device.

Single-circuit ones are designed exclusively for the operation of the main coolant (radiators, pipes, etc.), that is, they are purchased to provide heating. Most often, such devices are installed in dachas and in places where there is no water supply. In this case, a boiler is purchased for a single-circuit boiler to heat water in an autonomous water supply system.

Double-circuit boilers are 2-in-1 devices. They can both heat a house and provide hot water supply. The coolant and boiler in such a device are assembled into one unit. If hot water is not consumed, the coolant circulates in the heating circuit. As soon as the user opens the hot water tap, the system switches the valves so that the coolant is directed to the second circuit. This is the most popular type of gas boilers, which are installed in most apartments and private houses.

Choosing a floor-standing boiler: how not to make a mistake

Before you go to the store, you should carefully analyze the features of the heated object in order to clearly understand the operating conditions of the device. Based on this, the characteristics of the equipment are selected.

Gas unit power

One of the main factors determining the choice of boiler. Standard recommendations suggest determining the required power of the device from the following ratio: 10 sq.m of building will require 1 kW of power produced by the unit.

However, this is a very average figure. It does not take into account the heat loss of the building, the height of the ceilings in the room, the number of doors and windows, their thermal insulation and much more. If possible, a specialist should calculate the required boiler power.

One more thing. It is usually recommended to select a boiler with some power reserve. This is fair, but this reserve should not be large. Otherwise, this will lead to rapid wear of the equipment and constant excessive fuel consumption. For single-circuit boilers, the power reserve should not exceed 15%, for double-circuit boilers 25%.

Specifics of fuel consumption

If possible, it is advisable to choose the most economical boilers. These include all condensation models. Compared to traditional devices under similar conditions, they consume 15-30% less fuel. An electronic ignition system will also help you save money.

Standard piezo ignition requires constant operation of the pilot burner, which leads to excessive gas consumption. This is not necessary for an electronic system. Such boilers are more expensive, but during operation the investment quickly pays off.

Double-circuit boilers are very convenient for small buildings, as they allow you to simultaneously heat the house and provide it with hot water

Optimal number of circuits

It makes sense to think about purchasing a double-circuit boiler only if there is a need for hot water supply. In this case, it is worth installing a device with two circuits only in a building of small or medium size.

For large houses, installing double-circuit boilers is impractical, since the device’s power is often not enough for full operation. In addition, the security of the system suffers.

Priority heat exchanger material

Copper is not considered in this case. Only steel or cast iron. The first option is chosen if you want to save money. But you need to be prepared for the fact that in a few years you will have to change the heat exchanger. For long-term trouble-free operation of the boiler, a cast iron unit is chosen.

Design type and performance

For floor-standing gas boilers, efficiency is considered normal, varying in options from 80 to 98%. Condensing models differ in efficiency ranging from 104 to 116%. The higher this value, the more efficiently the boiler operates and uses less fuel.

For dual-circuit models, the performance of the DHW system can vary from 2.5 to 17 liters per minute. The performance and power of the unit affect its cost; the higher it is, the higher the price of the device.

Best control system

The most convenient and safe to use are boilers with automatic control. They are able to function autonomously, without constant control of the owner. These are expensive, complex systems.

It is also possible to use more budget-friendly manually controlled boilers, but in this case its operation will have to be controlled by turning the device on/off to obtain a comfortable temperature in the room.

An excellent option in the operation of a gas boiler is the presence of a built-in thermostatic sensor. If you don’t have one, it is recommended to purchase and install a thermostat so as not to waste energy and overload your heating equipment.

Floor-standing boilers with automatic control are considered the most convenient to use. They do not require constant monitoring, yet they work safely and efficiently

The rules for adjusting the automatic control unit of gas equipment are given in the article, the contents of which we advise you to familiarize yourself with.

Acceptable design and dimensions

The dimensions of the boiler and its appearance are selected based on the area of ​​the combustion room. Manufacturers offer a large selection of a wide variety of models of various designs and dimensions, which allows you to choose the device that is most suitable for a particular room.

It is important to remember that the boiler and additional equipment must be provided with completely free access

The best models of gas boilers are presented in the article, which sets out in detail the selection criteria and provides all the arguments on the basis of which you can make an informed purchase.

HouseChief editorial advice on choosing a floor-standing gas boiler

Purchasing such equipment for your home is a complex and responsible process. And expensive models are not always better and of higher quality than cheap ones. Therefore, before purchasing, it makes sense to read user reviews, of which there are a lot on the Internet. However, you should not read opinions on the manufacturer’s official website. They are unlikely to miss the negativity there. It is best to get acquainted with the opinions of people on large forums, such as Otzovik, IRecomend and the like.

When purchasing a gas boiler, you need to calculate the area that will be heated by it, and then add 10–15% to it. This will allow you to select a boiler that is ideal in terms of technical characteristics and will make the temperature in the house as comfortable as possible with rational fuel consumption.

You need to purchase a boiler in a specialized store

You should purchase a gas heating boiler in a large specialty store, although using online resources is also a good option. In any case, if the cost of the boiler is significantly lower than the market price, you should refuse such a purchase.

Types of siding

The choice of type of siding for exterior decoration directly depends on the material from which it is made. What kind of siding is there:

Vinyl

Decorating houses with vinyl siding has the ability to imitate various structures, such as wood, stone or brick. This siding has a sufficient number of advantages. The most important thing is an acceptable price category. Indeed, nowadays price is an important indicator when choosing a particular product.

I would like to note that vinyl panels are quite light, but at the same time strong and able to withstand natural disasters. In addition, it is possible to choose any texture and color scheme. This facing material has a very long service life, about 60 years, and is absolutely safe for health.

Wood

Wooden siding for the exterior of a house is a completely natural material that does not emit toxic substances, has a presentable appearance and perfectly retains heat in rooms. But, even despite such significant advantages, wood has its big disadvantages. Wooden siding is a flammable material and is also susceptible to insects and microorganisms, so it cannot be done without special and constant treatment. In addition, it has a fairly high price.

Metal

Sheathing a house with metal siding comes in two varieties, aluminum and zinc. This is one of the most durable facade materials with a long service life. It is not afraid of sudden temperature changes and unfavorable weather conditions. Covering a house with metal siding prevents the proliferation of harmful microorganisms. But it has the most undesirable phenomenon, which is susceptibility to rust.

Cement

The panels contain high quality cement with the addition of cellulose. This type of cladding material can depict decorative stone. In addition to its beautiful appearance, this material is 100% resistant to fire, hay rays and high humidity. Rot and fungus never form on it, and it is very easy to restore.

The only drawback of this material is that it is heavy, this must be taken into account during installation.

Ceramic

Siding of this type is made of clay and therefore its main advantage is environmental friendliness. This type of finishing appeared relatively recently and is now gaining popularity.

Tsokolny

Designed for finishing the basement of the house. Resistant to weather conditions and physical impacts. The sheets are smaller in size compared to wall siding. The appearance can have different colors, imitate stone or brickwork.
