The cost of a heat pump varies greatly and depends on several factors, including the type of heat pump, the capacity, the installation costs, and any additional adjustments to the heating system. Here are some expenses to consider:

1. Purchase cost of the heat pump:

   • The cost of the heat pump itself varies depending on the type (air-to-air, air-to-water, ground-to-water, etc.) and the capacity needed for the specific heating requirements of the home.

2. Installation costs:

   • The installation costs include labor costs for installing the heat pump, connecting it to the heating system, and integrating it into the existing electrical network.

   • Any modifications to the home, such as adjustments to radiators or the installation of underfloor heating, can also be added to the installation costs.

3. Ground or air heat exchanger:

   • For geothermal heat pumps, the costs for drilling a well for the heat exchanger in the ground can be significant.

4. Subsidies and tax benefits:

   • In some cases, governments offer subsidies or tax advantages to homeowners who choose heat pumps, thereby reducing the net investment costs.

5. Maintenance costs:

   • Although heat pumps generally have lower operational costs than conventional heating systems, there may be costs for periodic maintenance.

On average, the costs of a heat pump can range from several thousand to tens of thousands of euros, depending on the mentioned factors. It is important to compare quotes from different suppliers, consider potential subsidies, and take into account the long-term energy savings when assessing the costs of a heat pump installation.
