SoleWasserWärmepumpen

SoleWasserWärmepumpen, also known as geothermal heat pumps or ground source heat pumps, are a type of heat pump that utilizes the stable temperature of the earth to provide heating and cooling. These systems typically consist of a heat pump unit inside a building and a ground loop, which is a network of pipes buried underground. The ground loop circulates a fluid, usually a mixture of water and antifreeze, which absorbs heat from the earth in the winter and dissipates heat into the earth in the summer.

During the heating season, the fluid in the ground loop absorbs thermal energy from the soil, which remains at a relatively consistent temperature year-round, typically between 10-16 degrees Celsius. This warmed fluid then travels to the heat pump unit inside the building. The heat pump uses a refrigerant cycle to extract the heat from the fluid and transfer it to the building's heating system, such as radiators or underfloor heating. In cooling mode, the process is reversed. The heat pump extracts heat from the indoor air and transfers it to the fluid in the ground loop, which then releases the heat into the cooler earth.

SoleWasserWärmepumpen are known for their high energy efficiency and low operating costs. Because they tap into a stable underground temperature, they are less dependent on fluctuating outdoor air temperatures compared to air source heat pumps. This can lead to significant energy savings and a reduced carbon footprint. Installation requires sufficient land area for the ground loop, which can be installed horizontally or vertically.
