Ground Source (Geothermal) Heating & Cooling Systems

    Vitocal 300-G hero

    Using heat from the ground 

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

    The heat which is collected then can be used to heat radiators, heating systems and hot water in your home.

    As the ground remains a fairly constant temperature under the surface regardless of the time of year, a ground source heat pump is suitable for use all year round.

    Water heat pumps can also be used where water is available as a heat source.

    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.

    Domestic RHI

    Control via internet with ViCare & Vitoconnect

    The ViCare app offers new possibilities for controlling heating systems via the internet. The design of the ViCare graphic interface has been kept simple, enabling completely intuitive heating system operation.

    Vitoconnect internet interface

    Vitoconnect is the interface between the boiler and ViCare. It is not only compatible with new Viessmann heating systems, but is also available for many existing appliances. It is connected directly via a cable. A plug-in power supply unit is included in the standard delivery. A small accessory, measuring only 10 x 10 cm, is available for wall mounting

    Design & Technology

    The compression process is critical for the efficiency of a heat pump. Viessmann uses the most advanced components in its heat pumps. Their operation is characterised by quiet running, low vibrations and an extremely long service life without the need for maintenance. To generate heat, thermal energy is extracted from the  environment and used to evaporate a refrigerant that boils at a low temperature. The compressor compresses the gas this creates and raises it to a higher temperature level. A heat exchanger transfers the energy from the heated gas to the heating circuit. The refrigerant, which is still under pressure, condenses again and is expanded in an expansion valve. The cycle then begins again.

    Compact, quiet and attractive

    Our compact, floor standing heat pumps take up little space and are particularly quiet in operation – making them suitable even for installation near the living space.

    All of our heat pumps 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.
