Air source heat pumps are known as being one of the most energy-efficient ways to heat a home. Depending on the Coefficient of Performance (CoP) of air source heat pumps, they can achieve efficiency rates of 200-350%, as the amount of heat they generate is significantly greater than the electricity input per unit of energy. Compared to a boiler, heat pumps are up to 350% (3 to 4 times) more efficient, as they consume far less energy relative to the heat they output for use in the home.
The amount of energy an air source heat pump needs to run depends on several factors, including the local climate and seasonality, the ductwork and insulation condition and the property’s condition and size.
When calculating the amount of electricity you’ll need to run an air source heat pump, you need to consider its CoP. The higher it is, the better, because it means you’ll use less electricity to generate the amount of heat you demand.
Let’s look at an example…
For every 1 kWh of electricity, an air source heat pump can produce 3kWh of heat. The average annual demand for most UK homes is around 12,000 kWh.
12,000 kWh (heat demand) / 3kWh (heat produced per unit of electricity) = 4,000 kWh of electricity.
If your electricity is priced at £0.15 a unit¹, it will cost you £600 to run your air source heat pump.
