Ground Source (Geothermal) Heating & Cooling Systems

Using heat from the ground

A renewable form of energy, ground source heat pumps use the ground as their main energy source. They do this by utilising geothermal collectors or geothermal probes that are buried in your garden.

Ground source heat pump systems take heat energy from the ground and pass it through a heat exchanger into a heat pump, which works like a refrigerator but in reverse. Water heat pumps can also be used where water is available as a heat source.

These solutions provide heating and hot water for your home. Combined geothermal heating and cooling systems are also now available. As well as providing warmth during colder weather, these solutions work in reverse when it’s hot outside and provide cool air to help keep your home at a comfortable temperature year-round.

Ground source heating and cooling systems are becoming increasingly popular as people look for more environmentally friendly energy solutions for their homes. By harnessing natural, renewable resources, ground heat pumps and cooling systems can help you to cut your carbon footprint and bring your energy bills down. To further this, you could choose a setup that runs the heat pump using power generated on site by renewable power sources such as photovoltaic solar panels.

Design & Technology

To generate heat, heat pumps extract thermal energy from the environment. This energy is used to evaporate a refrigerant that boils at a low temperature. The resultant gas is compressed to raise it to an increased temperature level. A heat exchanger then transfers the energy from this gas to the heating circuit in your home, while the refrigerant condenses again and is expanded in an expansion valve. The process then starts again.

Viessmann heat pumps and geothermal cooling systems use the most advanced components to ensure quiet operation, minimal vibrations and an extremely long service life.
