What is an air source heat pump?

There are three main types of air source heat pumps: air to water, which connects to a wet central heating system; air to air, which circulates warm air through fans; and hybrid systems, which switch between air and water depending on factors like season or temperature.

These pumps work in four steps: drawing heat from outdoor air, using refrigerant to absorb it, compressing it to raise the temperature, and then using it to heat your home. Some models can even cool your home during warmer months.

Hear from our heat pump customers

Trustpilot
Green Home Systems installed a Heat Pump in our property. It was not a straight forward install as we did not have a wet system in place, so the house underwent ‘open heart surgery’. The team did a great job, always letting us know what was going on, and tidied up after every day. They did a fantastic job. For the first time since we moved in two years ago, the house has an even heat in every room, so for now the system seems to be working well!

This installation was first class. I was shocked at the quick turn around of the installation, team turned up just before 0900 and everything was up and running (and generating power) by 1530 without a trace of mess. Very accommodating and very professional from start to finish. Extremely happy customer.
