Frequently Asked Questions
How much does a heat pump cost?
Including installation, an air-source heat pump costs 15,000-25,000 euros, a ground-source pump 20,000-35,000 euros. Government subsidies (BEG) can cover 30-70% of costs depending on the situation.
What is the COP of a heat pump?
The COP (Coefficient of Performance) indicates how much heat energy is produced per unit of electrical energy. A COP of 4 means 1 kWh of electricity produces 4 kWh of heat. Higher COP means better efficiency.
What is the Heat Pump Cost Calculator 2026 — BEG Subsidy up to 70%?
The heat pump calculator computes the investment costs, operating costs and subsidies when switching to a heat pump.
How does the Heat Pump Cost Calculator 2026 — BEG Subsidy up to 70% work?
Enter the heat demand and heat pump type. The calculator computes electricity consumption (heat demand / COP), annual heating costs and compares with the previous heating system. The BEG subsidy (up to 70%) is deducted.
Key Data and Facts
BEG subsidy 2026: 30% basic + 20% climate bonus + 30% income bonus. Max. 70%. Typical COP air-source: 2.5-4.0. Investment air-source heat pump: 15,000-25,000 euros.
Step-by-Step Guide
How to calculate die costs einer Waermepumpe step by step: 1. Waermebedarf des Gebaeudes determine: Fuer ein typisches Einfamilienhaus (150 m2) liegt der Waermebedarf bei 10.000-20.000 kWh/year, je nach Daemmstandard. Altbau unsaniert ca. 150 kWh/m2, saniert ca. 80 kWh/m2, Neubau ca. 40-50 kWh/m2. 2. Waermepumpentyp choose: Luft-Wasser (guenstigste Anschaffung, JAZ 2,5-3,5), Sole-Wasser/Erdwaerme (JAZ 3,5-4,5, teurer), Wasser-Wasser (JAZ 4,0-5,0, selten). 3. Stromverbrauch calculate: Stromverbrauch = Waermebedarf / JAZ. 4. Jaehrliche Heizkosten: Stromverbrauch x Strompreis. 5. BEG-Foerderung 2026 abziehen: 30 % Grundfoerderung + bis zu 20 % Klimageschwindigkeitsbonus + 30 % Einkommensbonus (Haushaltseinkommen unter 40.000 EUR). Maximal 70 % auf foerderfaehige costs bis 30.000 EUR. 6. Vergleich mit Gasheizung erstellen: Gaskosten = Waermebedarf x Gaspreis.
Calculation Example
Einfamilienhaus, 15.000 kWh Waermebedarf, Luft-WP mit JAZ 3,0: Stromverbrauch = 15.000 / 3,0 = 5.000 kWh. Heizkosten: 5.000 x 0,37 EUR = 1.850 EUR/year. Investition 22.000 EUR abzgl. 50 % Foerderung = 11.000 EUR Eigenanteil.
