Look out of your window and what do you see? The house opposite? The road? Trees and fields? What we see is a free source of energy – the ground!

What is a Ground Source Heat Pump?

Ground source heat pumps (GSHPs) use pipes which are buried in the garden to extract heat from the ground. This heat can then be used to heat radiators, underfloor systems and hot water in your home.

Most heat pumps deliver up to 4kW of heat energy for every kW of energy input into the system, proving to be a very efficient way to heat your property.

How does a Ground Source Heat Pump work?

Heat pumps transfer the heat from underground by circulating a substance called a refrigerant through a cycle of alternating evaporation and condensation. A compressor pumps the refrigerant between two heat exchangers. In one heat exchanger, the evaporator, the refrigerant is evaporated at low pressure and absorbs heat from its surroundings. The refrigerant is then compressed en route to the heat exchanger, the condenser, where it condenses at high pressure. At this point, it releases the heat it absorbed earlier in the cycle.
