What is an Air Source Heat Pump?
An air source heat pump sometimes referred to as an air-to-water source heat pump, transfers heat from the outside air to water, which heats your rooms via radiators or underfloor heating. It can also heat water stored in a hot water cylinder for your hot taps, showers and baths.
The heat from the air is absorbed into a fluid. This fluid then passes through a heat exchanger into the heat pump, which raises the temperature and then transfers that heat to water.
For further information on how a heat pump works, including details on typical savings, system design and control, see this in-depth guide to heat pumps at the Energy Saving Trust website.
