Quite simply, a ground source heat pump system (GSHP) takes energy from the ground to provide heating and hot water.
The energy is generated by the sun and the heat can be extracted from pipes in the ground, from an underground aquifer or from a lake. Systems are extremely efficient and work in all weather conditions,
Air sourced heat pumps (ASHP) work in a a similar way to a ground source heat pump. However, rather than taking energy from the ground it takes it from the surrounding air to generate heat and hot water.
Compared to the equivalent GSHP, the air sourced systems are often cheaper to install, as you do not need to install the ground array, although may not quite match the performance coefficients.
GSHP systems can be used for a wide range of projects and system sizes, for domestic and commercial use.
Ranging from small single domestic installations to large commercial installations where multiple GSHP units can cater for all of the annual heating and hot water.
ASHPs are often used by domestic and commercial property owners.
