Ground Source Heat Pumps

How it works

‚Äč

Wherever you look you will find that ultimately all energy comes from the sun. Ground Source Heat Pumps are one way we can tap into this energy.

The sun and the rain ensure that the ground temperature stays  between 8ºC and 12ºC. The Heat Pump enables us to transform this low temperature heat that is stored in the ground into usable heat for buildings. 

By installing coils of pipe called 'ground arrays' in the ground and connecting them to a Heat Pump we can convert these low temperatures into usable heat for heating and hot water.

For every kW of electricity used by the Heat Pump we can produce up to 4 kW of heat.  

It is important that Heat Pumps are connected to the right type of heating systems. To work efficiently they need to output hot water at a temperature less than 50ºC. This means that they perform well with under floor heating or over sized radiators. They also need specific hot water cylinders to supply hot water.
