Air Source Heat Pumps
An air source heat pump (ASHP) is a system which transfers heat from outside to inside a building, or vice versa. Under the principles of vapor compression refrigeration, an ASHP uses a refrigerant system involving a compressor and a condenser to absorb heat at one place and release it at another. They can be used as a space heater or cooler, and are sometimes called “reverse-cycle air conditioners”.
In domestic heating use, an ASHP can be used to heat hot water-filled radiators, but most frequently are used for underfloor heating and/or hot water supply.
When correctly specified, an ASHP can offer a full central heating solution and domestic hot water without the need for a gas boiler.
