Autonomous heating for a private house is available, comfortable and varied. You can install a gas boiler and not depend on the vagaries of nature or failures in the centralized heating system. The main thing is to choose the right equipment and calculate the heating capacity of the boiler. If the capacity exceeds the heat demand of the premises, then the money for the installation of the unit will be wasted. In order for the heat supply system to be comfortable and financially profitable, at the design stage it is necessary to calculate the power of the gas heating boiler.
Basic values for calculating heating power
The easiest way to get data on the heating performance of the boiler by the area of the house: 1 kW of power is taken for every 10 sq. m. However, this formula has serious errors, because modern building technologies, the type of terrain, climatic temperature drops, the level of thermal insulation, the use of double-glazed windows, and the like are not taken into account.
To make a more accurate calculation of the boiler heating power, you need to take into account a number of important factors that affect the final result:
- the dimensions of the living space;
- the degree of home insulation;
- the presence of double-glazed windows;
- thermal insulation of walls;
- type of building;
- air temperature outside the window during the coldest season;
- type of heating circuit wiring;
- the ratio of the area of supporting structures and openings;
- heat loss of the building.
In houses with forced ventilation, the calculation of the heating capacity of the boiler must take into account the amount of energy required to heat the air. Experts advise making a gap of 20% when using the obtained result of the boiler's heat output in case of unforeseen situations, severe cold snap or a decrease in gas pressure in the system.
With an unreasonable increase in thermal power, it is possible to reduce the efficiency of the heating unit, increase the cost of purchasing system elements, and lead to rapid wear of components. That is why it is so important to correctly calculate the power of the heating boiler and apply it to the specified dwelling. The data can be obtained by a simple formula W = S * W beats, where S is the area of the house, W is the factory power of the boiler, W beats is the specific power for calculations in a certain climatic zone, it can be adjusted according to the characteristics of the user's region. The result should be rounded up to a large value in the event of heat leakage in the house.
For those who do not want to waste time on mathematical calculations, you can use the online gas boiler power calculator. Just keep individual data on the characteristics of the premises and get a ready-made answer.
| Window | Triple glazing Double glazing Regular (double) glazing |
| Walls | Good thermal insulation Two bricks or 150 mm insulation Poor thermal insulation |
| Window to floor ratio | 10% 20% 30% 40% 50% |
| Outdoor temperature | -10C-15C-20C-25C-30C-35C |
| Number of walls facing outside | OneTwoThreeFour |
| Room type above the calculated | Heated room Warm attic Cold attic |
| Room height | 2.5 meters 3 meters 3.5 meters 4 meters 4.5 meters |
| Room area | |

The formula for obtaining the power of the heating system
The online heating boiler power calculator makes it possible to obtain the required result in a matter of seconds, taking into account all the above characteristics that affect the final result of the data obtained. In order to use such a program correctly, it is necessary to enter the prepared data into the table: the type of window glazing, the level of thermal insulation of the walls, the ratio of the floor area to the window opening, the average temperature outside the house, the number of side walls, the type and area of the room. And then press the "Calculate" button and get the result of the heat loss and heat output of the boiler.
Thanks to this formula, each consumer will be able to obtain the necessary indicators in a short time and apply them in the design of the heating system.
You can choose a boiler of the required power on the Teplodar website https://www.teplodar.ru/catalog/kotli/ heating boilers from the manufacturer.
