Heat pump costs and purchase: what you should look out for

Heat pump costs and purchase: what you should look out for

Heat pumps are one of the most efficient technologies for sustainable heating. They use natural resources such as air, water or geothermal energy to generate heat - with minimal CO₂ emissions. But what costs are associated with the purchase and are there alternatives that offer additional financial benefits? In this article, we provide an overview of the cost factors and present the innovative heating systems from 21energy that combine heat and income.

Cost factors when purchasing a heat pump

The total cost of heat pumps depends on various factors:

  • Type of heat pump: air-to-water heat pumps are less expensive than ground source heat pumps, as there is no need for expensive boreholes for geothermal probes.
  • Sizing: The heating requirement of your home (depending on insulation and living space) determines the size of the heat pump.
  • Installation costs: Installation can be more complex and expensive in older buildings.
  • State subsidies: Attractive subsidy programs in Germany and Austria can significantly reduce the investment costs.

Cost overview of heat pump types

The following table provides an overview of the costs for different types of heat pumps:

Type of heat pump Price Special features
Air-to-water heat pump 8.000 € bis 14.000 € No complex drilling required
Geothermal heat pump 12.000 € bis 20.000 € Efficient, but expensive geothermal probe drillings
water-water-heat pump 15.000 € bis 25.000 € High efficiency, but cannot be installed everywhere
