For heating private houses, it is most advantageous to use gas heating equipment. This is due to the fact that gas is still considered the cheapest type of fuel. Such equipment is safe, economical and efficient.

We present to your attention the rating of gas boilers, compiled on the basis of feedback from consumers and specialists. If you decide to install gas heating in your house, then the overview of the devices below will help you navigate the variety of gas-fired boilers.

Gas boilers are divided into two types.

convection

The most common among boilers. The principle of its operation is quite simple. Gas through the burner nozzles enters the combustion chamber, where the flame flares up. It heats the heat exchanger with water, which enters the radiators through pipes and heats the room. As soon as the water temperature has reached the required temperature, the heating stops. The products of combustion are removed through the chimney. The efficiency of such a boiler is 90%. The remaining ten literally fly out into the pipe.

If the outlet temperature is below 57 degrees, then condensation will form on the walls of the combustion chamber, heat exchanger and chimney, which can lead to breakdowns, soot formation, and also to a reduction in the life of the device.

To prevent this from happening, as well as for more efficient use of thermal energy, a new type of boiler was designed.

Condensing

The efficiency of this device reaches almost 100% due to the fact that the energy is fully used for heating and no longer “flies into the pipe”. This was achieved with the help of another heat exchanger - a water economizer. It is there that carbon monoxide vapors cool down until condensate forms, which accumulates in a separate tank. When the vapor is converted into a liquid, useful thermal energy is released, which is transferred to the coolant.

The condensing boiler is bulkier and is usually installed in a separate room. The cost of the device is twice as much as that of traditional boilers.

Popular brands

Demand creates supply, which is probably why the market for gas heating equipment is so large. The more manufacturers, the more new models appear in stores. For an inexperienced user, this is a difficult choice, especially since few people are familiar with well-known brands. Still, this is a piece goods, I bought it once and forgot for a long time.

Which manufacturer's products should be considered reliable and of high quality?

• wolf. The German company produces boilers with very high efficiency. It is not yet very well known in the CIS, but it deserves the closest attention. Even budget models are of good quality and have built-in automation to ensure the most efficient operation.
• Vaillant. Also a German manufacturer. The products of this brand occupy more than twenty-five percent among other companies in the European market, which indicates quality, reliability and popularity.
• Bosch. This brand does not need advertising, it has long been a recognized leader in the production of equipment.
• STS and Bentone. Swiss companies. They have expensive products, but very high quality.

• Dakon. The Czech manufacturer produces budget models. It uses German high-quality components, modern automation systems, as well as careful quality control.

Just do not think that Russian companies do not produce quality products. By purchasing equipment of domestic manufacturers, the user can count on low cost, reliability and durability, high performance, as well as the availability of components and good after-sales service.

• "Zhukovsky Machine-Building Plant". Produces heating equipment for over 40 years. In some boilers it uses imported automation. None of the models is independent of the mains. Efficiency - up to 92%. High degree of reliability and long service life.
• Borinsky. This plant has been dealing with boilers for more than two decades. Almost all models are equipped with high-quality foreign automation, are non-volatile, have a relatively modern design and affordable price.
• Lemax. The Taganrog plant offers gas boilers with a special coating of heat exchangers that protects against corrosion. Models are also produced with cast-iron heat exchangers, which are rightfully considered the most reliable. All equipment has high efficiency and is non-volatile.

What features to look out for

In order to correctly and competently choose a gas boiler, carefully consider the following criteria.

• Power. The most important parameter. It completely depends on the area of ​​the heated premises and the specific coefficient for the region of residence. For example, if you live in the middle lane, then the value of the coefficient for every 10 m² is 1-1.2 kW, in the south - 0.7-0.9 kW, in the north - 2 kV. To calculate the power of a boiler for a house of 300 m² in a temperate climate, you need to carry out the following calculations: 300 * 1/10 \u003d 30 kW.
• Mounting method. Boilers are wall and floor. The first ones are compact, do not take up much space, are silent and affordable. The second ones are more powerful, bulky, and often require a separate room for their installation.
• The number of contours. Single-circuit devices are designed only for heating, double-circuit devices also provide hot water supply.
• Safety. It is desirable that the boiler be able to automatically turn off in all abnormal and emergency situations.

Important factors when choosing a device are the consumption of gas and electricity, efficiency, the availability of programmable conditions for night and day heating, price.

• Be responsible for calculating power. If it is not enough, then the room will heat up for a long time and cool quickly. A powerful boiler, on the contrary, will lead to overheating - this is an unprofitable use of resources.
• If there is no separate, well-ventilated room and chimney, then a natural draft floor boiler will not suit you. It is better to opt for wall-mounted boilers with forced draft.
• Do you already have hot water? Then you should not spend money on a double-circuit boiler.
• A biometric heat exchanger requires high-quality water without impurities. So if you do not have a water filter built into the water supply system, then you will not save on such a boiler, because scale in the heat exchanger is guaranteed to lead to a breakdown.

Conclusion

As you can see, the choice of a boiler should be treated responsibly and with knowledge of the nuances. It is better not to rely on chance, but to turn to professional gas workers. They will help to correctly calculate the power and advise which boilers are suitable for heating your premises.

Such equipment is quite durable and safe. To help in choosing the best option for heating equipment, a rating of gas boilers was compiled, which were especially popular in Europe and among our compatriots in the first half of this year.

Five leaders in the production of gas heating equipment

The vast majority of heating gas equipment is represented on the domestic market of climate technology by European manufacturers, as well as some representatives of the Asia-Pacific Economic Community.

Benefits of installing a gas boiler for heating in Russia are obvious: gas supplies are more stable, it will not be turned off unexpectedly, and gas is cheaper than electricity. What do we need from a good gas boiler? To keep the house warm, so that the device is safe and lasts a long time.

Temperature indicators for all models are approximately the same. All heating boilers comply with safety standards, but more expensive models have a complex multi-stage self-diagnosis system, effective protective automation. Reliability and service life are determined by the quality of parts and assembly (and, of course, you must follow the rules of use!). We studied the opinions of experts and customer reviews and selected the best models of gas boilers that combine reliability, safety and efficiency.

First, let's figure out which manufacturers of gas boilers deserve our attention in the first place.

Which company's gas boiler is better?

The vast majority of gas boilers in our stores are imported. Mostly European. In our opinion, the rating of the best foreign manufacturers of gas boilers looks like this:

1. Wolf (Germany)
2. Vaillant (Germany)
3. BAXI (Italy)
4. Protherm (Slovakia)
5. Bosch (Germany)
6. Buderus (Germany)
7. Navien (Korea)

and some others.

Among our domestic manufacturers of gas boilers, we single out two plants:

1. Zhukovsky Machine-Building Plant (ZHMZ). Produces boilers brands AOGV(single-circuit, heating) and AKGV(two-circuit, heating and hot water).
2. OOO Zavod Conord. Located in the city of Rostov-on-Don. Produces gas boilers and columns CONORD, solid fuel boilers DON, industrial boilers and other equipment.

How to calculate the optimal value of the thermal power of a gas boiler?

Why take a boiler more powerful than required, if this will certainly lead to unnecessary costs not only at the time of purchase, but also during operation. On the other hand, giving away a lot of money and getting cold in winter, washing your face with cold or slightly warm water is, to put it in television serial language, a loss of losses!

The simplest method of selecting the golden mean: 1 kW per 10 m² of serviced area. However, this is very approximate and does not take into account some of the most important parameters. For example, such as: the climatic coefficient of a particular region, the degree of thermal insulation of the walls, the level of probable heat loss, the volume (and not just the area) of the room, etc.

Therefore, a more accurate calculation is needed. There are two ways: use publicly available formulas that take into account the above criteria (it becomes possible to remember your school years) or act more rationally and use a special calculator, which is a dime a dozen on the network.
