How does an Air Source heat pump work? 

An air source heat pump is usually placed outdoors at the side or back of a property. It takes heat from the air and boosts it to a higher temperature using a heat pump. The pump needs electricity to run, but it uses about a third less electrical energy than the heat it produces. Take a look at our graphic below for a visual representation of how an air source heat pump functions.

The above diagram shows a COP of 3 but modern system are usually from 3.5 to 4.5 COP. Generally the more the cost of the system the higher the COP meaning more efficiency and lower the cost to run.
