Ground source heating

At a 300% efficiency rate, a ground source heat pump will prove a cost efficient as well as an environmentally friendly investment that will help you save up to 40% on heating bills compared to conventional heating systems. 

How a ground source heat pump works A mixture of water and anti-freeze is pumped around the ground loop and absorbs the naturally occurring heat stored in the ground. The pump itself consists of an evaporator, a compressor and a condenser - together these take the heat from the water mixture, transfers it to your domestic heating system and increases the temperature in the process. A ground source heat pump increases the temperature from the ground by between one and a half and four times – so if the ground temperature is 12°C, the output would be between 18 and 48°C).
