In case of humidity of the room where the appliance is located, place the absorbing salts within the hearth.
Protect the internal cast iron parts with neutral Vaseline, if you wish to keep the aesthetic appearance unchanged in
time.

16. 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
3 3
have 150 m x 50 W/m = 7500 W or 7.5 kW.
Therefore as main heating, a 10 kW appliance is sufficient.
