Kensa Heat Pumps have provided their 8kw single compact heat pump as part of extension works at Grade Ruan School, Cornwall. The extension to the school was built to current building standards at the time and was highly insulated.
The school fitted a “wet” underfloor heating system throughout with plenty of good quality insulation underneath. This along with the high insulation meant it was an ideal application for the use of a ground source heat pump to provide the space heating for the building. Two 70 metre deep closed loop boreholes were drilled within the playground area to provide the heat source and energy for the heat pump. The manifold for the boreholes was placed in a purpose built lockable cabinet mounted on the external wall of the school.
These are connected to an 8 kW “Compact” heat pump manufactured by Kensa Heat Pumps. The heat pump was designed to provide space heating with the school opting for the production of their domestic hot water via a set of solar thermal panels. This provided the school with all the space and domestic hot water they required and more importantly low running costs.
