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
3
(for 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
3 .
Let’s suppose one wishes to heat a room of 150 m
3
(10 x 6 x 2.5 m) in an insulated apartment. In this case, it is necessary to have 150 m
3
x 35
w/m
3
= 5250 w or 5,25 kw. As main heating, a 8 kw device is therefore sufficient.
