Air Source Heating - The Basics

This section gives you some information on how air source heat pumps work - but for some background on why they are becoming such a popular choice, for both environmental and economic reasons, take a look at our 'Selecting a Heat Pump' section. 


Air Source Heat Pumps - How It Works

Air source heating uses an air source heat pump to extract thermal energy (heat) from the air outside  and converts this into heating and hot water for your home enabling you to reduce your carbon footprint and your heating bills.


The pumps are designed to work even in cold air and are suitable for lots of different homes providing they are well insulated. They run very quietly and are compact so they can be installed in a small outside space.  

They need electricity to operate, but 75% of the energy needed for your heating and hot water is generated from a renewable energy source, the outside air, and only 25% comes from your electricity supplier.


For every 1Kw energy put in, the heat pump generates up to 4Kw of output.
