The winter period is due not only to a change in weather conditions, but also to preparations for the heating season. To maintain a constant temperature, it is necessary to calculate the required power of the electric boiler. The heating system must produce thermal energy according to the heat loss of the building. The possibility of abnormal temperatures in winter is also taken into account.
Heat transfer from the boiler - why do we need calculations
Calculations of power and heat transfer of an electric boiler are the main characteristics. Incorrect calculations can lead to an overpayment for the heating period in case of excess power, a deficiency will lead to interruptions in hot water supply and low room temperature. Before buying a heating system, it is first necessary to calculate the capacity of an electric heating boiler by area. Before this, the heat loss of the room is definitely determined. According to the data obtained, a model of an electric boiler is selected. You can also use the online calculator to calculate the power of the boiler.
Calculation of power by area - the basic formula
To determine the power of the required electrical unit, it is enough to know the area of the heated room. The average calculation for the Russian Federation is 1 kW is enough to heat 10 square meters. m. These figures are approximate, so the calculation also includes the height of the building's ceilings and climatic conditions. For the appropriate calculation, coefficients are used according to the regions.
The indicators for the middle band are suitable for structures with ceilings of 2.5-2.7 m. If the height of the ceilings is higher, then the real data is divided into the norm, and a correction factor is obtained.
THE NOTE. There are special sites that will perform online calculation.
Climatic coefficients for Russian regions:
- 1.5-2.0 for the northern regions;
- 1.2-1.5 for the Moscow region;
- 1.0-1.2 for the middle band;
- 0.7-0.9 for the southern regions.
REFERENCE. For an apartment, the coefficients differ slightly: from above, a heated apartment is 0, 7, a heated attic is 0.9, an unheated one.
These calculations are taken into account only if the system is sent only to maintain a constant temperature in the structure. If you expect that the unit will heat water, then you need to add 20-25%. It is also worth considering the period of abnormal temperatures in the cold, plus another 10%.
The power of the electric boiler is calculated according to the formula W = S x Wud / 10 m².
Highlights
Modern heating systems are made not only with adjustable power, but also with the function to simulate power. But professionals insist on the purchase of a heating unit with constant power so that there is no malfunction in the event of a power outage.
REFERENCE. When buying, be sure to consult with a specialist, he will answer all questions and give practical advice.
The main indicator of the electric boiler is a thermal indicator, it is the heat loss replenishment and uninterrupted supply of hot water that depends on it.
Power is calculated according to:
- Heating area.
- Building materials of walls and floors.
- Glazing area.
- The level of thermal insulation.
- The number of external walls.
- Insulated or non-insulated attic.
- Type of glazing.
- Ceiling height.
Having made the correct calculation of the power of the heating boiler, it will provide you with body and hot water for the entire winter period. Of course, in this situation it is better to contact specialists in order to avoid overpayments for electricity supply, or interruptions in hot water. A professional organization will take all the necessary calculations for itself and select the appropriate heating system for the home.
