An air source heat pump could cost around £1,992.60 to run per year based on a household using 18,000kWh of energy.
The price of energy varies and the amount of energy needed to heat a home can differ as well, making it challenging to give an exact figure for how much it may costs to run a heat pump. However, we've put together an example based on average fuel cost figures between April and June for a four-bedroom home using 18,000kWh of energy per year.
To estimate the total running costs, we divide the home heat requirement by the heat pumps presumed efficiency, then multiply it by the fuel price:
18,000kWh ÷ 300%) x 33.21p per kWh of electricity = £1,992.60
It's important to note that this is only an estimate and actual costs of running a heat pump may vary depending on various factors such as the size of the home, insulation quality, energy usage patterns and cost of electricity.
