Bewley Homeson the site of the famous Rafts Boathouse at Eton

Energy World; 01/03/2014

Luxury homes on the site of the famous Rafts Boathouse at Eton overlooking the River Thames and Windsor Castle are all to be heated by an innovative system that makes use of the heat stored naturally underground. The 13 apartments being built by Bewley Homes will have their heat supplied by a shared ground source heat pump system that should result in substantial savings in carbon emissions.

The £500,000 system is being installed and will be remotely monitored by GI Energy, based in Coventry, which has already completed more than 200 MW of installations in schools, universities, hospitals, commercial developments, police headquarters and housing.

Ground source heat pumps consist of a network of pipes underground, called earth loops, attached to heat pumps. Liquid pumped through the loops extracts heat from the ground. Heat pumps then raise its temperature to a level that can be used for heating a building. For cooling, the process is reversed. Traditionally, loops have been buried either close to the surface in a horizontal array, or vertically in deep boreholes, but GI Energy has also buried loops in underground aquifers, lakes, reservoirs and even inside the piles that underpin many buildings in constrained urban sites.
