Air source heat pumps absorb heat from the outside air. This heat can then be used to heat radiators, underfloor heating systems, or warm air convectors and hot water in your home.
An air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can get heat from the air even when the temperature is as low as -15° C.
Heat pumps have some impact on the environment as they need electricity to run, but the heat they extract from the ground, air, or water is constantly being renewed naturally.
Unlike gas and oil boilers, heat pumps deliver heat at lower temperatures over much longer periods. During the winter they may need to be on constantly to heat your home efficiently.
You will also notice that radiators won't feel as hot to the touch as they might do when you are using a gas or oil boiler.
An air-to-water system distributes heat via your wet central heating system. Heat pumps work much more efficiently at a lower temperature than a standard boiler system would.
This makes them more suitable for underfloor heating systems or larger radiators, which give out heat at lower temperatures over longer periods of time.
Lower fuel bills, especially if you are replacing conventional electric heating.
Potential income through the UK governments Renewable Heat Incentive (RCI).
No fuel deliveries needed.
Can heat your home as well as your water.
Minimal maintenance required.
Can be easier to install than a ground source heat pump.
