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.

Eligible for the Domestic RHI scheme

As ground source heat pumps utilise a renewable fuel source, they are eligible for the UK government’s Domestic RHI scheme. Through the scheme, you could be eligible for quarterly cash payments for seven years after installing a ground source heat pump.

Control via internet with ViCare & Vitoconnect

The easy to use ViCare app allows you to control your heating system via the internet. Its graphic interface has been designed to enable completely intuitive heating system operation.

Vitoconnect internet interface

Vitoconnect is the interface between the boiler and ViCare. As well as being compatible with new Viessmann heating systems, it is available for a range of existing household appliances. The interface is connected directly using a cable, and a plug-in power supply unit is included in the standard delivery. This small accessory, which measures just 10cm x 10cm, is available for wall mounting.

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.

Compact, quiet and attractive

Our compact, floor standing heat pumps take up little space and are particularly quiet in operation - making them suitable for installation in a range of places, including near the living space. They also feature easy to use control interfaces and are ready to connect direct from the factory.

Solar ready

All of our ground source heat pumps are designed ready for use with power generated on site, for example by photovoltaic systems.
