GRD installs every type of heating tube
To prove the applicability and combinability of various geothermal heating tube systems with the GRD system, four different types of heating tubes were installed from March until April 2010 at "The Homestead" stately home, close to a village called Hope in Derbyshire (Great Britain) using the GRD method and then carrying out the “Thermal Response Test” (TRT). After completion of the operation the produced installation for heating the stately home was applied (21 kW heating load).

Manor farm harvests geothermal heat

Manor Farm is located on the edge of the beautiful village of Eyeworth and was constructed in 1865. The new owners drew up a detailed restoration and modernisation plan for the building which incorporated under floor heating. To keep the heating costs to a minimum they opted for a Ground Source Heat Pump to provide heating and hot water. Following careful consideration, the Geothermal Radial Drilling (GRD) method was chosen for the drilling process.
