Percentages of Energy and Carbon Dioxide Saved by Heat Pumps
Supplied by Energy Saving Trust

Air Source Heat Pumps
The savings below are based on a detached property, and relate to space heating only.
They assume a typical system, with a seasonal performance factor of 2.5
Figures have been rounded

Sample saving statements:
Replacing an oil heating system with an air source heat pump for space heating in a detached home can reduce running costs by 55%, and carbon dioxide emissions by 30%.

Ground Source Heat Pumps
The savings below are based on a detached property. They assume that the heat pump provides 100% of space heating and 50% of water heating, with the remaining 50% of water heating provided by electric immersion heater.

They assume a typical system, with a seasonal performance factor of 3.2.
