Air-to-water heat pumps are suitable for many types of homes and are the most common type of domestic heat pump, with tens of thousands of installations across the UK. However, there are a few things you should consider before deciding whether a heat pump is right for you.
- could lower your fuel bills
- will cut your carbon emissions
- can heat your home and hot water
An air-to-water heat pump transfers heat from the outside air to water, which heats your radiators or underfloor heating. It can also heat water stored in a hot water cylinder for your hot taps, showers and baths.
Heat from the air is absorbed into a fluid. This fluid then passes through a heat exchanger into the heat pump, which raises the temperature and then transfers that heat to water.
For further information on how a heat pump works, including details on typical savings, system design and control, see our in depth guide to heat pumps.

How much does an air-to-water heat pump cost?
The cost of an air-to-water heat pump varies depending on the brand, model and size of heat pump, the size of the property, whether it’s a new build or an existing property, as well as whether you need to change the way you distribute heat around your property. Typical costs are around £7,000 to £13,000, and we recommend speaking to at least three installers to provide a quote for your heat pump system to give you the best idea of likely costs for your home.
Will a heat pump save me money on my energy bill?
Running costs will depend on how your heat pump is designed and how it is operated. Savings on your energy bill will also be affected by the system you are replacing.
