An air source heat pump (ASHP) is usually placed outdoors at the side or back of a property. It takes heat from the air and boosts it to a higher temperature using a heat pump. The pump needs electricity to run, but it should use less electrical energy than the heat it produces.
An air source heat pump system can help to lower your carbon footprint as it uses a renewable, natural source of heat – air. The amount of CO2 you’ll save depends on the fuel you are replacing. For example, it will be higher if you are replacing electric heating rather than natural gas.« Back to Glossary Index
