How to read the outputs
Water-only thermal energy
volume × temperature rise. Default preview: 367 kWh.
Adjusted thermal energy
after retained heat-loss allowance. Default preview: 411 kWh.
Electrical energy
thermal energy ÷ COP 5. Default preview: 82.1 kWh.
Estimated heating time
30 kW delivered output. Default preview: 13.7 hr.
Estimated input power
delivered output ÷ COP. Default preview: 6 kW.
Retained loss allowance
after cover or shelter reduction. Default preview: 12%.
Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Water thermal energy is based on volume and temperature rise. Apply the retained heat-loss allowance. Electrical energy = thermal energy ÷ COP. Cost = electrical kWh × electricity price.
FAQ
Pool Heating Cost Calculator questions
Why does COP reduce electricity use?+
A heat pump transfers heat from the air, so delivered thermal energy can be several times the electrical energy consumed.
Does this include daily heat maintenance?+
No. It estimates one initial temperature increase. Daily maintenance depends strongly on evaporation, wind, covers and weather.
Can this estimate gas-heater cost?+
Not directly. Gas heaters use fuel input and combustion efficiency rather than heat-pump COP.
