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 do need electricity to run, but the heat they extract from the ground, air, or water is constantly being renewed naturally and the savings should always outweigh the costs.
Heat from the air is absorbed at low temperature into a fluid. This fluid then passes through a compressor where its temperature is increased, and transfers its higher temperature heat to the heating and hot water circuits of the house. There are two main types of air source heat pump systems:
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.
An air-to-air system produces warm air which is circulated by fans to heat your home. They are unlikely to provide you with hot water as well.
The benefits of air source heat pumps:
- Lower fuel bills, especially if you are replacing conventional electric heating
- potential income through the UK government’s Renewable Heat Incentive (RHI)
- lower home carbon emissions, depending on which fuel you are replacing
- 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.
- can cut your C02 emissions by up to 60%, dependent upon the existing fuel you use for your heating.
We currently recommend and install Samsung and LG heat pump systems.
