The price of a heat pump for a 100 square meter house depends on many factors, such as the type of heat pump, energy efficiency, brand, and installation. Below, I provide a cost estimate based on different heat pump options.

Prices for Heat Pumps for 100 Square Meters

1. Air-Water Heat Pump

• System Price: 5.000 € – 10.000 €
• These pumps are the most popular and often the most economical to install, as they do not require major renovation or geothermal work.
• Air-to-water heat pumps extract heat from the air and transfer it to the home's heating system (e.g., radiators or underfloor heating).
• For 100 square meters, the system should be capable of covering the thermal needs of the house (approximately 6-8 kW for an average house).
• Installation: 1.500 € – 3.000 €
• The installation involves connecting the pump to existing heating systems (radiators or underfloor heating) and may require modifications if the radiators are not efficient for low water temperatures.

2. Geothermal (Ground) Heat Pump

• System Price: 10.000 € – 20.000 €
• Geothermal heat pumps are very efficient, as they draw heat from the ground. However, their installation is more expensive due to the excavation work required to create the geothermal collectors.
• These pumps are ideal for larger homes and areas with low outdoor temperatures.
• Installation: 5.000 € – 10.000 €
• Geothermal installation requires more specialized work and the creation of geothermal pipes or boreholes.

3. Water-Water Heat Pump

• System Price: 15.000 € – 25.000 €
• Water-to-water heat pumps use heat from groundwater or other sources and are the most efficient of the other options, but they require specialized work.
• This type of pump is more expensive and requires the presence of groundwater or the installation of a source to pump heat.
• Installation: 5.000 € – 10.000 €
• The installation includes the specialized placement of the water pumping system and the necessary work.

Additional Cost Details

• Possible upgrade of radiators: If your existing radiators are not efficient for the low temperatures offered by the heat pump, you may need to upgrade or replace them with larger or more efficient models. The cost of upgrading radiators can range from €500 to €2,000 per radiator, depending on the type and size.
• Operating costs: The cost of a heat pump depends on the efficiency of the system and the energy it consumes. However, heat pumps are generally much more efficient than traditional heating systems, thus reducing heating costs in the long run.

Total Estimated Cost

For a 100 square meter house, the total cost to install a heat pump (including the pump and installation) can range from:

• For air-to-water heat pump: €6,500 to €13,000.
• For geothermal (ground) heat pump: €15,000 to €30,000.
• For water-to-water heat pump: €20,000 to €35,000.

Conclusion

Choosing the right type of heat pump depends on your needs and the infrastructure of your home. For a 100 square meter house, air-to-water heat pumps are the most economical and practical solution, while geothermal pumps, although more expensive to install, offer higher efficiency and less maintenance requirements.
