Basis of calculation
All fuels are compared at the same heat output — without accounting for boiler efficiency, using the same methodology as the official Heizomat calculator.
| Fuel | Calculation | Calorific value |
|---|---|---|
| Heating oil | 11.8 kWh/kg × 0.85 kg/L | 10.03 kWh/L |
| Natural gas | 11.8 kWh/kg × 0.8 kg/m³ | 9.44 kWh/m³ |
| Electricity | direct heating, 1 kWh/kWh | 1.00 kWh/kWh |
| Heat pump | seasonal performance factor (SPF) | 4.00 kWh/kWh el. |
| Wood chips | 4.3 kWh/kg × 230 kg/srm (25 % moisture) | 989 kWh/srm |
| Logs | 4.5 kWh/kg × 350 kg/rm (15 % moisture) | 1,575 kWh/rm |
| Wood pellets | 4.7 kWh/kg × 1,000 kg/t (8 % moisture) | 4,700 kWh/t |
