Air source heat pumps absorb heat from the outside air. This heat can then be used to warm water for radiators, underfloor heating systems, warm air convectors or hot water in your home.

An air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can extract heat from the air even when the outside temperature is as low as minus 15° C. Heat pumps have some impact on the environment as they need electricity to run, but the heat they extract from the ground, air, or water is constantly being renewed naturally.

An air-to-water system uses the heat to warm water. Heat pumps heat water to a lower temperature than a standard boiler system would, so they are more suitable for underfloor heating systems than radiator systems. An air-to-air system produces warm air which is circulated by fans to heat your home. Heat from the air is absorbed into a fluid which is pumped through a heat exchanger in the heat pump.
