Heat pump vs gas boiler
Estimate annual space-heating demand from floor area and insulation class, then compare heat-pump electricity cost (by SCOP) against a gas boiler.
Open calculatorHeating fuel comparison
Converts your annual useful space-heating demand into fuel volume and cost using fuel calorific values and boiler efficiency (or SCOP for a heat pump). Direct electric resistance is modelled at 100% point-of-use efficiency. Default calorific values: natural gas 10 kWh/m³, wood pellets 4.8 kWh/kg, coal 7 kWh/kg, firewood 4 kWh/kg, heating oil 10 kWh/L.
Annual space-heating demand — typically 10,000–22,000 kWh for a detached house.
kWh
Average seasonal efficiency for gas, oil and solid-fuel boilers (enter as a decimal, e.g. 0.90).
Average heat-pump SCOP over the heating season — typically 3.0 to 4.0.
