Ground Source Heat Pumps use natural, ambient heat from the ground to generate heat.
The solutions are made up of a ground loop (conductive heating circuits buried underground) and a heat pump situated at ground level. Pipes can be laid in horizontal trenches or vertical boreholes.
A Glycol fluid mixture is pumped around the ground loop and absorbs heat stored in the ground.
The pump takes the heat from the fluid and transfers it through a heat exchanger and compressor before feeding it into the heating system to provide heating and hot water to the property.
A ground source heat pump increases the temperature extracted from the ground by between one and a half and four times. A ground temperature of 12°C will see the Heat Pump create an output between 18 and 48°C.
The Benefits:
Heat Collection Options:
Heat pumps are well suited to new build homes and renovations as the building standards are higher. However, they can provide substantial savings as a partial heating system using the existing oil/gas boiler as a back up for when the weather is particularly cold and the existing radiator system.
However, installing Heat pumps into new build homes also means that it is easier to install heating systems such as in-screed under floor heating, which is more efficient than overlay and provides greater thermal conductivity for heating.
How much could you earn?
Ground Source Heat Pumps are eligible for the Domestic Renewable Heat Incentive (RHI) and the Non Domestic RHI scheme.
