Ground Sun Ground Source Heat Pumps

Heat Pump Installers

Ground Sun has installed ground source heat pumps (GSHP) in London and nationwide for lots of domestic and commercial developments. 

These units use the natural renewable energy stored in the ground to provide heating and hot water for your home or business.  The earth beneath your feet stores energy from the sun at a fairly constant temperature throughout the year. This heat can be conducted to a liquid flowing through ground loop pipes buried in the earth, pumped through a heat exchanger, and utilised to provide space heating and hot water.


Installation of Heat Pumps

The length of the ground loop needed depends on the size of the property that needs to be heated. The two most popular methods of burying the ground loop are by drilling a bore hole of around 150 metres into the ground (borehole method), or by digging an open trench and burying the ground loop one metre below the surface (slinkies).  Ground Sun has developed innovative methods of exploiting the energy stored beneath your feet, making that energy easier and cheaper to extract.  Our engineers have years of experience in drilling underground pipe and cable laying for utility companies. We have adapted and developed that expertise for use with ground heat pumps, using the latest technologies in GSHP systems.

Ground Sun design, supply and install renewable heating and cooling using heat pumps. We are passionate about heat pump technology and are main agents and distributors of Austrian-manufactured Ochsner Heat Pumps and UK-manufactured Kensa Heat Pumps. These heat pumps are amongst the most efficient and advanced in the world and range from 2kW to 1.8MW so are suitable for all projects from small domestic to large scale commercial schemes.

We are accredited installers under MCS (Microgeneration Certification Scheme). MCS is an internationally recognised quality assurance scheme, supported by the Department of Energy and Climate Change. Accreditation assures consumers that the company installs heat pumps to the highest quality industry standards, it also ensures that our installations are eligible under the Government’s Renewable Heat Incentive (RHI) scheme. See Grants and Incentives for more details.
