Compare heating systems
Same property, different COP values — see the difference between a gas boiler (COP 1) and a heat pump (COP 3.5).
Heating cost estimator
Estimate seasonal heating energy and cost from area, heat loss, hours, COP, and price per kWh.
What is it for
Provide property area (m²), heat loss (W/m²), operating hours per season, system COP, and price per kWh. The planner computes energy (kWh) and cost. Informational only — for precise calculation consult an energy auditor or your supplier.

Formula: energy (kWh) = (area × heat loss × hours) ÷ 1000 ÷ COP; cost = energy × price/kWhEnergy 3,771.43 kWh
Total cost 24,514.29
This calculation is an estimate. Actual consumption and cost depend on property condition, weather and tariff. For precise calculation, consult an energy auditor or your energy supplier.
