Air Source Heat Pumps
Air source heat pumps (ASHPs) 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.
Different from a ground source heat pump, 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.
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.
Ground Source Heat Pumps
Mainland Europe, Scandinavia and North America have been drilling for heat for some time now. Sometimes up to 200 metres. Why? Because GSHP systems are able to take heat from deep into the earth and convert it into usable space and hot water heating in domestic and commercial situations.
Alternatively, around 6 metres below the earths surface there is thermal stability that can be converted into heat for the winter months and cooling in summer. This system is more extensive and involves excavating and the introduction of ground loops.
Ground source heat pumps (GSHP) systems extract this heat from the ground. The energy is then transferred for use in heating systems – for hot water and central heating.
