Як розрахувати необхідну потужність котла

It is very important to correctly calculate the power of the heating equipment. If it exceeds the real needs of the  building for heat, then part of the heating costs will simply be thrown away. And equipment with low performance will not provide the room with the necessary amount of heat.

The calculation of boiler power is influenced by a number of factors:

The climatic conditions in which you live;The area of the heated room;The degree of insulation of the house;The amount of heat required to heat water.

Next, we calculate using a simple formula: P=k×S/10,

where P is the power of the boiler,

S – heated area,

k – heat loss coefficient.

The heat loss coefficient may vary depending on the type of building:

• For buildings with increased thermal insulation, well-insulated walls, floors, roofs and windows with double glazing - k = 0.8
For structures with low thermal insulation or non-insulated at all, this coefficient will be the highest - k = 1.2-1.5

It may seem that the exact calculation of the boiler power is not so important. After all, you can simply buy more powerful equipment, so to speak, «with a margin». We assure you that you should not do this. It can lead to:

• Decrease in boiler efficiency

If you plan to use a two-circuit system for water heating, you need to increase the power of the equipment by 25%. We do not recommend choosing a boiler that has a larger power reserve, as this can lead to a decrease in efficiency.

Now that you have already decided on the boiler capacity, it's time to call us! Boilers of TM «Altep» have a wide range of capacities for any type of premises.
