Set within the Stroud Valleys, Gloucestershire, the owners of Little Ruin wished to remove their ageing oil boiler as they undertook the modernisation of the two-hundred-year-old property.

Following a detailed consultation, isoenergy recommended a 12kW CTC ground source heat pump with a 300L hot water cylinder and a 300L heating buffer tank. The plant room was connected to 750m of collector pipework buried in the adjoining paddock. isoenergy designed the collector array to work around the steep gradient of the valley to ensure there would be no airlocks within the pipework at unvented high points.

The plant room was remote from the main house so we buried two pre-insulated distribution pipes to ensure there would be minimal temperature losses as the heating and hot water was distributed to the building.

Our client now enjoys an efficient sustainable energy system and a significantly reduced carbon footprint.

Key features:

  • CTC 12kW ground source heat pump
  • Joule 300L hot water tank
  • Cordivari 300L heating buffer tank
