Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Current cost = thermal demand ÷ current efficiency × fuel price. Heat-pump cost = thermal demand ÷ COP × electricity price. Payback = net investment ÷ annual savings.
FAQ
Heat Pump Payback Calculator questions
Why use seasonal COP rather than rated COP?+
Seasonal performance better reflects changing outdoor temperatures, cycling and defrost operation.
Should cooling savings be included?+
They can be added separately when the heat pump replaces an older cooling system, but they are not included here.
Can energy prices change the payback?+
Yes. The result is sensitive to both electricity and existing-fuel prices.
