What is an Air Source Heat Pump?

In the simplest terms, they behave like a reverse fridge. They take cold air from the outside and, through a series of clever processes, create hot air that can heat the water in your central heating.

Along with solar, they are the ultimate in renewable energy as they use an inexhaustible source of power – air!

Whereas your gas boiler burns gas to create heat, which also creates nasty emissions, an Air Source Heat pump uses pressure and evaporation to the very same thing.

The Science of Air Source Heat Pumps

Air Source Heat Pump Fan

This is the external part of the system that draws air into your home. Drawing ambient air from the outside and using it to kickstart the whole process.

Refrigerant

The air from outside is passed over a series of pipes full of refrigerant. This is a cold liquid that reacts to any change in temperature. The external air heats this liquid up and it becomes a gas.

Compression

The refrigerant gas isn’t quite warm enough to heat water at first. So, to increase the temperature, the cool gas is passed through a compressor to ‘squish’ the molecules together, causing it to heat up.

Heating Water

The super-heated gas is then fed into pipes in a water tank. This is where the heat transfer happens, and the pipes heat the water and the water cooler the refrigerator.

Heating your home

The heated water is then fed into the radiators, or underfloor heating, in your home – the condensed gas returns to a liquid and the whole process starts again.

Cheap To Run

Air source heat pumps (ASHPs) are between 200-400% efficient. To put that into context, it means for every 1 kWh of electricity they use, they produce between 2 and 4 kWh of heat.

Air Source Heat Pumps - FAQ

ASHP is simply the acronym for Air Source Heat Pump.

Air Source Heat Pumps are specifically designed to work with central heating systems. The older your system the more likely it will be that you will need to replace a few radiators here and there. If you have underfloor heating you will, in most cases, be Air Source Heat Pump ready.

Air Source Heat Pumps are far more efficient than a gas boiler, saving you around a third on your average gas bill.

An air source heat pump is designed to last two to three times longer than a conventional gas boiler. They generally need much less maintenance also.

ASHPs have fewer mechanical components in comparison to other heating systems. This means they take less looking after and require less maintenance. Just make sure you clean them regularly and check the filters, fans, and coils.

Air source heat pumps raise the water pressure in your home - so if your shower is currently a weak dribble, you're in for a very pleasant surprise.

Unlike ground or water source heat pumps, you don’t need a borehole or ground works to fit an air source heat pump. This means you don’t need permission or surveys either.
