How Do Air Source Heat Pumps Work?
An air source heat pump will generally be stored outside, at either the back or the side of a property. It absorbs heat from the air, which is transferred into a fluid. This fluid is then passed through a compressor and the temperature is increased. This hot fluid is then sent into the heating and hot water circuits in the property. Other types of air source heat pumps similarity extract heat from the air, but this heat is then compressed and released into the home through warm air convectors or fans.
You may be wondering how it can take heat from the air in cold climates and conditions (like that of the UK) – well air source heat pumps can extract heat from the air in temperatures as low as -15° C.
Heat pumps generally use less electricity than the heat they produce. Unlike gas or electric boilers heat is delivered at a lower temperature over a longer period of time. To heat your home over winter you may need to have the heat pump on constantly. Radiators may also not feel hot to the touch compared to using a gas or oil boiler system.
