Ground Source with Boreholes East Grinstead

  • 4 x 115m boreholes
  • 2 x 10KW Stiebel-Eltron ground source heat pumps
  • 2 x 300l cylinders
  • 1 x 400l heating buffer
  • 1 x 400l accumulator
  • UFH throughout on 4 floors
  • MVHR

This was a very impressive, multi-million pound, new build property over four floors with underfloor heating throughout.

Being off the gas grid the customer was keen to avoid an oil boiler and install a modern heating system. As the property was insulated above the demands of Current Regulations and had underfloor heating (UFH) and mechanical ventilation and heat recovery (MVHR) throughout, supplemented by a solar PV array, it made perfect sense to go with a ground source heat pump.

We installed two x 10KW Stiebel Eltron ground source heat pumps in the basement plant room along with two x 300l Stiebel cylinders for the hot water a large 400l buffer cylinder for the hot water and a 400l accumulator to ensure sufficient water pressure across the many bathrooms.

The heat was derived from four x 115m-deep boreholes in the paddock in front of the house, fed into the basement by 63mm header pipes from the manifold chamber.

The customer now has a beautifully warm home and lashings of hot water from a system that is cheaper to run than a fossil-fuel boiler and should easily last 20 years with minimal maintenance.
