Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Full-load electrical input = thermal capacity ÷ COP. Average demand applies the load factor and adds backup heat. Monthly energy = average kW × operating hours.
FAQ
Heat Pump Running Cost Calculator questions
Why use a load factor?+
Heat pumps rarely operate at full rated capacity for every scheduled hour.
Should backup resistance heat be included?+
Yes when it operates. Enter its average electrical input during the modelled schedule.
Is COP constant?+
No. COP changes with source and delivery temperatures, cycling and defrost.
