Calculation of the boiler output, for heating the house

Autonomous heating for a private house is available, comfortable and varied. It is possible to install a gas boiler and not depend on the vagaries of nature or failures in the central heating system. The main thing is to choose the right equipment and calculate the heat output of the boiler. If the capacity exceeds the heat needs of the room, the money for installing the unit will be thrown into the wind. For the heat supply system to be comfortable and financially profitable, at the stage of its design it is necessary to calculate the power of the gas heating boiler.

The basic values ​​for calculating the heating power of the

The easiest way to get the boiler's heat output data for the area of ​​the house is to take 1 kW of power for every 10 sq. M.m. However, this formula has serious errors, because modern building technologies, the type of terrain, climatic temperature differences, 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 heating capacity of the boiler, it is necessary to take into account a number of important factors affecting the final result:

• dimensions of the living quarters;
• degree of house insulation;
• the presence of double-glazed windows;
• wall thermal insulation;
• building type;
• air temperature outside the window in the coldest time of year;
• type of heating circuit layout;
• ratio of the area of ​​bearing structures and openings;
• building heat loss.

In houses with forced ventilation, the calculation of the heating capacity of the boiler must take into account the amount of energy needed to heat the air. Experts advise to make a gap of 20% when using the result of the boiler's thermal output in case of unforeseen situations, a strong cooling or a decrease in the gas pressure in the system.

If the heating capacity is unreasonably increased, it is possible to reduce the efficiency of the heating unit, increase the cost of purchasing system components, and lead to a rapid wear of the components. That is why it is so important to correctly calculate the power of the heating boiler and apply it to the indicated dwelling. The data can be obtained from the simple formula W = S * Wud, where S is the area of ​​the house, W is the boiler's factory capacity, Wd.- 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 to a large value in conditions of heat leakage in the house.

For those who do not want to waste time on mathematical calculations, you can use the gas boiler's online power calculator. Just keep individual data of the features of the room and get a ready answer.

The formula for obtaining the capacity of the heating system

The calculator of the capacity of the heating boiler online makes it possible in seconds to obtain the desired result taking into account all the above characteristics that affect the final result of the received data. To properly use this program, you need to enter the prepared data into the table: the type of window glazing, the level of wall insulation, the ratio of floor areas to the window opening, the average temperature outside the house, the number of side walls, the type and area of ​​the room. And after clicking the button "Calculate" and get the result for heat loss and heat output of the boiler.

Thanks to such a formula, each consumer will be able to obtain the required indicators in a short time and apply them in the design work of the heating system.
