Air source heat pumps are an efficient method of providing both heating and cooling solutions for your home in any climate. These pumps operate by absorbing heat from the external air into a liquid refrigerant, which is maintained at a low temperature, and subsequently releasing it indoors in a manner similar to an air conditioning unit, albeit in the opposite direction. The liquid refrigerant is compressed using electricity to elevate the temperature and unlock its stored heat, which is then distributed to your radiators or underfloor heating.
