Written for MyKith: the essentials, without the noise.
A heat pump works like a refrigerator in reverse. It collects heat from the outside air, the ground or water and moves it indoors using a refrigerant cycle powered by electricity. Because it moves heat rather than generating it by burning fuel, a well-installed system can deliver several units of heat for every unit of electricity it uses, even in cold weather.
Heat pumps run best at lower temperatures for longer periods, so good insulation and correctly sized radiators or underfloor heating make a large difference. Before deciding, ask an accredited installer for a heat loss survey of the whole house rather than a quick estimate. Check which local grants or incentives apply, since these can change the cost considerably.
