12KW Heat Pump & Boreholes for a renovation in Herts

Better Planet was instructed to design, supply and commission a ground source heat pump, for this property in Hertfordshire in connection with a full renovation and extension. As no gas from the grid was available a ground source heat pump was the natural choice. With limited land available for horizontal ground loops, boreholes were the best option. Like for all our projects involving boreholes, we obtain a geological report from the British Geological Survey detailing the ground conditions. This allows us to determine the correct depth of the boreholes. In this case the heat pump needed to be supported by two boreholes, 113 meters each.

Location: Hertfordshire
