19 Sep A beginner’s guide to air source heat pumps
Air source heat pumps are becoming a popular alternative to traditional heating systems as households look for efficient, low-carbon ways to warm their homes. They work by extracting heat from the outside air and transferring it indoors, even when temperatures are close to freezing.
How air source heat pumps work
There are two main types of air source heat pumps: air-to-water and air-to-air. Air-to-water systems connect to a central heating system, making them suitable for radiators or underfloor heating, while air-to-air pumps circulate warm air directly into rooms.
The technology is efficient, producing more heat energy than the electricity required to run it. A typical unit generates between 2.5 and 4 units of heat for every unit of electricity consumed. Performance varies depending on insulation, system design, and correct installation.
Benefits, challenges, and installation considerations
Air source heat pumps emit no carbon dioxide at the point of use and can reduce reliance on fossil fuels. They can also provide year-round climate control, with some systems offering cooling in addition to heating; however, installation requires outdoor space for the unit and, in the case of air-to-water pumps, sufficient radiator or underfloor capacity.
Initial installation costs can be high, although government grants are available to offset expenses. Maintenance needs are relatively modest, with servicing recommended every two to three years.
