How much do ground source heat pumps cost?
The cost of a ground source heat pump installation varies according to the type of collector we can use to collect heat from the ground. Boreholes, trenches or single pipe installations all cost different amounts. A very rough guide would be £1.10 for each kilowatt hour of the annual heat demand shown on your EPC. So for a heat demand of 30,000kWh per year a ground source heat pump installation would be in the region of £33,000. If we assume an efficiency of 400% the RHI payments for the system would be £4,275 per year for 7 years which comes to £29,925 so the net cost could be a little as £3,000, and don’t forget you will be saving money and carbon emissions all the time you use the heat pump.
