What is an Air Source Heat Pump?
An air source heat pump transfers heat from the outside air to water which subsequently heats your home via radiators or underfloor heating. It can also heat water stored in a hot-water cylinder for later use via taps, showers, and baths etc.
How do They Work?
Heat from the air is absorbed into a fluid which passes through a heat exchanger into the heat pump, this raises the temperature and transfers that heat to water.
Are They Suitable for Me?
Air source heat pumps are suitable for many types of homes however the following points should be considered:
Where will it go – the unit will be external and must be fitted to a wall or fixed on the ground with surrounding space to allow for a good flow of air.
How loud is it – noise is created by large fans moving air but unless the heat pump is working very hard, i.e. in cold weather, the volume will be similar to a fridge.
How will my home be heated – most homes will already have radiators or underfloor heating but if not then these must also be installed.
Do you have a hot-water cylinder – as a heat pump does not provide hot-water on demand a cylinder will be needed to store the hot-water produced.
How Much Will They Cost?
The cost will vary depending on the size of the heat pump, the size of the property, whether the building is existing or a new build, and whether amendments are required to the existing heat distribution system installed.
Will They Save Me Money on Energy Bills?
Running costs will depend on how the heat pump is designed and subsequently operated, and will also depend on the system being replaced.
