Geothermal heat pump

Heat is extracted from the ground via geothermal probes (a frost-proof liquid circulates through the probes and heats up), which is then brought to a higher temperature level to produce heating water or hot water with the help of a heat pump. Since the temperature of the ground is more constant and in winter also higher than the outdoor air temperature, geothermal heat pumps are more efficient than air-source heat pumps. In combination with floor heating, geothermal heat pumps allow passive cooling of the building in summer (Free Cooling). The installation at a single-family home takes about two weeks.

Advantages:

- No fossil fuels

- Very efficient and cost-effective operation

- Geothermal probes are not visible and audible

- Geothermal probes have a very long service life of over 50 years and therefore lead to an increase in the value of the property

- Cost-effective and ecological cooling function

Disadvantages:

- High investment costs

- Not feasible everywhere
