At the moment, due to the difficult situation in the country and the beginning of the heating season, many Ukrainians began to consider options for lowering prices for utilities, and since now solid fuel boilers remain one of the most profitable heating options, the beginning of the excitement for this type of product is felt. In this article, we would like to tell you how to correctly calculate the power of such equipment for your premises.
There are several main criteria that help determine the power of a solid fuel boiler:
- area of the room;
- thermal insulation (additional insulation of premises with foam or mineral wool);
- room height.
On average, when choosing such devices, the power is taken at the rate of 1 kW = 10 sq. m. premises. A more accurate calculation takes into account the area (S), the height of the room (h) and the presence of additional thermal insulation. If everything is clear with the first two indicators, we take the data based on the characteristics of our room, then for the presence /absence of thermal insulation, two coefficients (k) are added to the formula: 60 - for buildings that do not have additional thermal insulation and 40 - these are rooms with additional insulation.
The calculation formula will look like this:
N = S * h * k , where N is the power of the solid fuel boiler in W.
For example, let's calculate heating with a solid fuel boiler a room with an area of 230 sq. meters, ceiling height 2.5 meters with and without thermal insulation.
With thermal insulation: 230 * 2.5 * 40 = 23,000 W. As a result, we get that a 23 kW boiler is suitable for such a room.
Without thermal insulation: 230 * 2.5 * 60 = 34,500 W. A boiler with a capacity of about 35 kW is used for this room.
Most manufacturers on their resources provide a calculator for calculating the power of boilers, depending on certain parameters. In fact, much more factors must be taken into account (what the house is built of, the presence of internal and external insulation of the room, how the heating system is located, the presence of plastic or glass windows in the rooms, and a number of different indicators) and it is better to leave this question to specialists who are engaged in production or the installation of such equipment, about the choice of a solid fuel boiler, we advise you to check with the same people, they will orientate which type and brand of solid fuel boiler will best suit your needs and budget.
