How does an air source heat pump work?

1. Air source heat pump takes in air from outside to heat a liquid refrigerant

2. Using electricity, the pump compresses the liquid to increase its temperature. This then condenses back into liquid to release stored heat

3. Heat is sent to radiators or underfloor heating, the remainder is stored in a hot water cylinder

They take heat energy out of the air to heat your house and supply hot water, like a fridge, but in reverse. An ASHP (Air Source Heat Pump) system is extremely efficient in addition to having excellent eco credentials.

The typical output of an ASHP is three times as much heat for every unit of energy used to extract heat from the air, making it approximately 300% efficient!

Benefits of air source heat pumps include:

• Environmentally friendly, low-carbon source of heat

• Highly effective, producing about three times as much energy to heat a house as it does to remove it from the air.

• Eligible for government Boiler Upgrade Scheme

• An air source heat pump system is suitable for most urban properties because it requires little outdoor space.
