In order to find out the optimum number of heating-and-ventilation devices necessary to heat premises and continuously maintain the desired temperature, it is necessary to define the so-called heat demand. It will compensate heat loss in the premises (through the walls, floor, roof, gates, etc.).
Heat loss in a room depends on:
When heat demand is calculated, heat gains should be considered apart from heat losses. Heat gains may be caused by machines working indoors, office equipment and also people who generate heat and moisture.
One should not forget about heat demand in connection with the need to heat the ventilation air.

The example was elaborated on the basis of figures and relations found in a guide book entitled, "Heating and air conditioning" by Recknagel, Springer, Hofmann, Schramek, EWFE Gdańsk 1994.
