Ground Source Heat Pumps

consistent geothermal heat reducing costs & CO2.


Ground source heat pumps (GSHP) require less energy to generate heat than conventional methods. For every 4kW of heat produced they consume just 1kW of electricity. This gives GSHPs an efficiency of 400%.  Ground Source Heat pumps achieve this because they don’t create the thermal energy, they just transfer it, and subterranean earth temperatures are relatively constant through all the seasons.

Ground Source Efficiency

Ground source or geothermal heat pumps can save up to 70% on heating costs and up to 50% on cooling costs. Ground source heat pumps that are also used for cooling can reduce energy consumption and corresponding emissions by more than 40% against air source heating and over 70% against electric resistance heating with standard air-conditioning equipment.

How it works – the science bit!

G-GSHP™ systems are loop based systems that transfer considerable amounts of heat. They represent a thermo-physical system, which resembles the functioning of a refrigerator. In contrast to the refrigeration unit the geothermal pump condenser acts as a heat exchanger, which generates thermal energy for the consumer. Subsequently, the heat exchange process is further supported by the evaporator unit, which absorbs the heat from the coolant and distributes it into a premises as heat.

Environmentally Friendly

G-GSHP™ ground source heat pumps will lower your carbon emissions as they use natural underground heat. When powered with direct renewable energy such as Solar PV or grid supplied renewable energy, GSHPs become a zero carbon solution!

Even when operated on grid supplied power they are 400% efficient, which compared to traditional fossil fuelled heating of 70-90% efficiency.
