Ground Source Heat Pumps Work?
A ground source heat pump is installed, as the name would suggest, partly underground surrounding your business premises or home.
Natural heat is extracted from the ground, created by solar energy from the sun or rain fall. Pipes full of cold liquid are placed under the ground, known as ground arrays. As heat is naturally drawn from warm to colder areas, the heat from the ground is transferred to the pipes, warming the liquid they contain.
This low grade heat is then passed through an evaporator which heats liquid refrigerant, the liquid refrigerant is then compressed, turning the liquid refrigerant into gas.
Next , this now high grade heat is extracted from the hot gas, and passed into water. This water then feeds into your heating system.
The now cooled gas reverts back into a liquid and the cycle begins again!
