The best gas boilers for apartments and private houses: powerful, economical and, most importantly, safe.

What gas boiler is better to buy
The power of thermal equipment is the first thing to be determined before purchase. It is calculated through the heating area, taking into account the climate zone. At first, with a standard ceiling height of up to 3 m, you can get by with simple calculations: multiply the area of housing by the coefficient for your region, and divide the total by 10. As a result, you will get the estimated boiler power in kW.
Power factors for different regions of Russia:
1. southern region 0.7-0.9
2. middle lane 1-1,2
3. moderately cold climate 1.2-1.5
4. northern region 1.5-2
Not only the organization of the space, but also the safety of using gas equipment depends on the method of installation of the boiler. The wall mount will save space, but the compactness of the model will entail a number of technical limitations. The burner, exchanger, pump and control electronics will be too close to each other, which will create a tense temperature mode of their work and complicate maintenance.
Compact wall models have power limitations - they are more suitable for an apartment than for a private house. Floor-standing boilers are usually installed in separate rooms, so their overall dimensions, as well as their heat output, are not limited by anything but common sense.
Types of gas burners do not depend on the selected type of boiler, but they determine the principle of its operation and performance:
- Atmospheric burners are inexpensive and virtually silent. But they burn out indoor air and have low efficiency.
- Supercharged equipped with a blower air coming from outside. Boilers with such burners are effective and do not require mandatory installation in a separate room.
- Modulation burners with adjustable power can be equipped with a second heating stage or electronically controlled heat transfer. Their efficiency and efficiency increases simultaneously with the price of the boiler.
