CAST IRON RINGSThe cast iron rings needs to be periodically cleaned by using sandpaper (grain 150) without touching the enamelled parts..IMPORTANT: to avoid rust DO NOT forget pots or pans on the cold stove. This would create rust rings, unpleasant to see and difficultto remove.13. CALCULATION OF THE THERMAL POWERThere is not an absolute rule for calculating the correct necessary power. This power is given according to the space to be heated, but itdepends also largely on the insulation. On an average, the calorific value necessary for a properly insulated room is 30 kcal/h per m3 (foran external temperature of 0°C).Given that 1 kW corresponds to 860 kcal/h, it is possible to adopt a value of 35 W/m3.Let’s suppose one wishes to heat a room of 150 m3 (10 x 6 x 2.5 m) in an insulated apartment. In this case, it is necessary to have 150 m3x 35 W/m3 = 5250 W or 5,25 kW. As main heating, a 8 kW device is therefore sufficient.Approximate combustion value Required quantity in relation to 1 kg of drywoodFuel Unit kcal/h kWDry wood (15% humidity) kg 3600 4.2 1,00Wet wood (50% humidity) kg 1850 2.2 1,95Wood briquettes kg 4000 5.0 0,84Brown coal briquettes kg 4800 5.6 0,75Normal anthracite kg 7700 8.9 0,47Coke kg 6780 7.9 0,53Natural gas m3 7800 9.1 0,46Naphtha L 8500 9.9 0,42Electricity kW/h 860 1.0 4,1914.
