Air source heat pumps

Extract the heat in the outside air and, during circulation, raise the temperature to provide heating and hot water. Designed to sit outside the home, the ASHP is connected to the heating and hot water systems and although powered by electricity - like the GSHP - it will provide up to three times more usable energy than it consumes.
