CALCULATION OF THE THERMAL POWER.

There is not an absolute rule for calculating the correct necessary power. This power is given according to
the space to be heated, but it depends also largely on the insulation. On an average, the calorific value
necessary for a properly insulated room is 40 kCal/h per m
Given that 1 kW corresponds to 860 kCal/h, it is possible to adopt a value of 50 W/m
Let's suppose that one wishes to heat a room of 150 m
necessary to have 150 m
Therefore as main heating, a 10 kW appliance is sufficient (see Table 5).
