How does an air source heat pump work?
An energy-efficient air source heat pump (ASHP) works like a fridge but in reverse. It absorbs heat from the outside air and circulates it through your heating system. An air source heat pump helps you:
- Enjoy reliable heating and hot water all year round
- Lower your carbon footprint
- Save energy and tonnes of carbon(1) over time
