So how do air source heat pumps work? To put it very simply, they absorb heat from the air outside, compresses it to create energy and use this to heat your home. Just like a fridge, which draws in air from outside then cools it rapidly, the air source heat pump does the same thing but in reverse.
The ASHP sits outside your home, looks similar to an air conditioning unit. The heat in the air is used to heat a liquid refrigerant which evaporates. The pump then compresses the vapour, increasing the temperature. A heat exchanger is then used to warm water which can be used throughout your home – for hot water, in radiators or underfloor heating.
Unlike gas and oil boilers, air source heat pumps deliver constant heat at lower temperatures over much longer periods. It’s set to start working automatically meaning you’ll always have hot water and is great at maintaining a consistent environment in your property. Gone are the days of juggling the thermostat. But remember: a well-insulated home is essential.

The systems are smart and the intelligent energy efficient control system including via an App allow full control of your homes heating and hot water from anywhere, using your smartphone, tablet or PC. Clever stuff.
