Rehau helps exploit ground energy in the Highlands

With no mains gas available for a remote building in the Highlands of Scotland and difficult access for vehicles to deliver oil, a ground-source heat pump was installed to provide heating and hot water. Rehau carried out the work for this large stone property. It involved the installation of six Rehau Raugeo Pe-Xa probes at an average depth of 80 m in the ground to supply a Viessmann heat pump. These probes are linked using Rehau’s Raupex 50 mm PE-Xa pipework in a square Tichelman grid formation to eliminate the need for a multi-port manifold system in the property’s plant room. The Tichelman grid runs alongside the 50 m-long drive to the heat pump in the plant room. Rehau’s Rauthermex pre-insulated district-heating pipe then delivers the warm water a further 90 m to the main house and 20 m to a newly converted barn. This renewable-energy installation meets the entire 29 kW heating requirement, and its running costs are about half those of an equivalent oil-fired system. The boreholes were drilled by Albion Drilling Services.
