Savings Potential of Installing a Heat Pump
These are the typical savings for a ground source heat pump:
These are the typical savings for a air source heat pump:
Costs do not include distribution system e.g. underfloor heating. For full details of energy saving assumptions see accompanying note. However, savings for GSHP assume pump provides 100% space heating and 50% of domestic hot water, with the remaining 50% heated by electicity. Savings for ASHP assume it provides 100% space heating only.
