Quick calculation · heat pump

What difference does a heat pump make?

From your gas consumption to the electricity use of a heat pump: how much electricity is added, how much gas you no longer use, and what that saves per year.

1. Your gas consumption

Gas per yearm³/yearFrom your annual statement: heating, hot water and cooking together.Of which cookingm³/yearCooking on gas is usually 30–60 m³ per year; 0 if you already cook electrically.

2. Which heat pump?

Type Hybrid (with the boiler) Fully electric

Share of heating by the heat pump%A hybrid heat pump usually takes over 60–80% of the heating; hot water stays with the boiler.Efficiency (SCOP)How much heat per kWh of electricity, averaged over the year. With radiators usually 3–3.5, with underfloor heating 4–4.5; ground source higher. It is in the specifications.

Heat emitters Radiators Underfloor or low temperature

3. Your prices

Gas price€/m³Example rate incl. energy tax and VAT; it is in your contract.Electricity price€/kWhExample rate for a fixed contract, incl. energy tax and VAT.Fixed gas costs per year€Fixed supply costs and grid costs for gas, from your annual statement. These disappear if you cancel the gas connection (then cooking is electric too).Price of the heat pump (optional)€From your quote, after deducting the subsidy (ISDE); then the tool calculates the payback time.

An indication, not a quote. 1 m³ of natural gas gives about 8.8 kWh, of which a central-heating boiler delivers about 90% as heat. Hot water is a quarter of the gas for heating and hot water. Maintenance, depreciation and better insulation are not included.
