Running costs depend on the size of the property and system. The typical UK home requires about 12,000 kW of heat annually. An air source heat pump may create 3 kW of heat for each 1 kW of electricity it consumes. As a result, it will use 4,000 kW to fulfil the demand. As a rough example, with electricity priced at £0.13 per unit, annual running costs will be £520.
This is by no means a hard and fast rule. If you get electricity from your own renewable source, such as a solar PV installation, the running costs will be eliminated. Speak to one of our experts for more clarity about your savings from an air source heat pump.
