Frequently Asked Questions About Heat Pump Financing
Yes, combining subsidies and loans is explicitly allowed and recommended. You first receive the BAFA grant and then finance only the remaining costs with a loan.
The maximum subsidy is 70% of eligible costs (max. 30,000 euros). This consists of 30% basic funding, 30% income bonus, 20% climate speed bonus, and 5% efficiency bonus.
From February 2026, heat pump outdoor units may have a maximum sound power level of 60-70 dB(A) depending on the distance to the property boundary. This may require noise protection measures.
With current gas and oil prices, a subsidized heat pump typically pays for itself in 8-12 years. After that, you save 1,000-2,000 euros annually on heating costs.
