Down Farmhouse

The owners of this farmhouse on an estate in Surrey had been using fuel oil to heat the property and provide hot water. In order to reduce running costs, they approached isoenergy to look into the suitability of the property for a ground source heat pump.

This house is a good example of where isoenergy has used different collector methods to collect energy for a ground source heat pump. Part of the energy is collected from the ground using horizontal trenching and the remaining energy is collected from a small mill leat nearby. Neither one of the collector locations would have been enough to provide all the energy required so this hybrid system was designed.

Key features:

• 22kW Ecoforest ground source heat pump system
• 1,200 metres of collector array in hybrid configuration
• Provides all the heating and hot water for the farmhouse
