A heat pump promises efficient heating and independence from fossil fuels. Before the decision is made, there is a crucial question: What costs will you have to face? In this article, you will find a comprehensive overview of all costs of a heat pump.

‍

How much does a heat pump cost?

The price of a heat pump is between 8,000 and 18,000 euros, depending on the type and output. You pay 3,000 to 20,000 euros for the installation, including installation and development of the heat source. The total costs therefore amount to 14,000 to 38,000 euros.

‍

How much does an air heat pump cost?

You pay 8,000 to 17,000 euros for an air heat pump, depending on the output and model. You pay 3,000 to 8,000 euros for the installation. The total costs therefore amount to 11,000 to 25,000 euros, which makes the air heat pump the cheapest type of heat pump.

‍

How much does a geothermal heat pump cost?

The costs of a geothermal heat pump are between 15,000 and 38,000 euros, including installation and development of the ground. You pay between 10,000 and 18,000 euros for the heat pump itself. The installation costs amount to 5,000 to 20,000 euros, depending on the type of geothermal heat exchanger.

‍

The costs of a geothermal heat pump vary depending on the geothermal heat exchanger, soil conditions and heating capacity. Deep drilling for geothermal probes is more expensive than area collectors or soil baskets. Rocky soils further increase installation costs. With area collectors and soil baskets, you can carry out the earthworks yourself in some cases and reduce costs.

How much does a groundwater heat pump cost?

A water-to-water heat pump costs between 12,000 and 18,000 euros. You pay 5,000 to 12,000 euros to build a well system and 2,000 to 3,000 euros for the installation of the heat pump. The total costs are 18,000 to 33,000 euros.

Here is an overview of the cost items:

‍

How much does a heat pump cost in an old building?

The total cost of a heat pump in an existing single-family home is 15,500 to 43,000 euros. The purchase of the heat pump costs 8,000 and 18,000 euros. You pay 3,000 to 20,000 euros for the installation, including installation and development of the heat source. The costs for dismantling and disposing of the old heating system are between 1,500 and 5,000 euros.

‍

In addition to purchase and installation costs, further adjustments may be required, such as:

• Radiator replacement: 500 — 1,000€ per low-temperature radiator
• Adjustment of the heat distribution system: 1,000 — 5,000€
• Hydraulic balancing: 800 — 2.500€

For a heat pump to work efficiently, further renovation measures can be useful, such as insulating the building envelope or replacing windows. Which measures are required depends on the condition of the building. An energy consultant will help you identify appropriate adjustments and inform you about funding opportunities.

‍

Are there subsidies for heat pumps?

Heat pumps are used as part of federal funding for efficient buildings (BEG) supported by grants and low-interest loans.

When replacing an old heater, you can KfW subsidy 458 use. It covers up to 70% of eligible costs and a maximum of 30,000 euros. This means that you can receive subsidies of up to 21,000 euros for your single-family home.

‍

In addition to the subsidy, there is the KfW loan 358/359 with an effective annual interest rate of 0.01%. This can be used in addition to existing subsidies and enables loans of up to 120,000 euros per residential unit. Householders with an annual income of up to 90,000 euros benefit from particularly favourable interest rates. The loan makes it easier to finance the heat pump, especially when there are high purchase and installation costs.

‍

What are the running costs of heat pumps?

Depending on efficiency and heat demand, the annual operating costs of a heat pump are between 800 and 2,400€. The costs are Power consumption, maintenance and insurance together. Electricity costs represent the biggest cost factor.

The exact operating costs depend on the efficiency of the heat pump, the insulation standard of the building and the electricity tariffs.

‍

Is it worth the investment?

Heat pumps are worthwhile because they have low operating costs thanks to their high efficiency. Investment through government funding is particularly attractive when it comes to heating replacement, as subsidies of up to 70% are possible. As a result, the purchase costs are significantly reduced and the heat pump pays for itself more quickly. Heat pumps are a sustainable and cost-effective alternative to gas heating systems, especially in well-insulated buildings.

The following comparison between an air heat pump and a gas heating system illustrates the economic efficiency.

‍

The lower operating costs and funding result in a Savings of 26,000€ in 20 years compared to gas heating. In the long term, a heat pump is therefore the more economical choice.
