Energy content of firewood at 20% humidity:
Island islands - 1650 kWh / rm
Birch logs - 1500 kWh / rm
Coniferous wood –1300 kWh / rm
Wound injuries 850 - kWh / rm
Gray alder cracks - 700 kWh / rm
Space meter (rm) - 1 m3 of stacked finer timber with intermediate spaces.
In the case of birch logs, the annual heating cost of the building:
The heating cost norm for new buildings is 150 kWh/m². If the efficiency of the wood boiler is 80%, then the annual cost of logs for one square is 150/(1500×0,8) = 0,125 rm/a for a 150 m2 building, the annual cost of logs is 0,125 × 150 = 18,75 rm1 rm of birch logs costs xx eur
