14. 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 30 kcal/h per m
an external temperature of 0°C).
Given that 1 kW corresponds to 860 kcal/h, it is possible to adopt a value of 35 W/m
Let's suppose one wishes to heat a room of 150 m
x 35 W/m = 5250 W or 5,25 kW. As main heating, a 8 kW device is therefore sufficient.
