Air source heat pumps
What is an air source heat pump? An air source heat pump (sometimes referred to as an air-to-water heat pump) transfers heat from the outside air to water. This in turn heats rooms in your home via radiators or underfloor heating. It can also heat water stored in a hot water cylinder for your hot taps, showers, and baths.
