Ground Source Heat Pumps

Ground Source Heat Pumps

A Ground Source Heat Pump (GSHP) uses pipes that are buried in the garden to extract heat from the ground. This heat can then be used to heat radiators, underfloor or warm air heating systems and hot water in your home.

A GSHP circulates a mixture of water and antifreeze around a loop of pipe, called a ground loop. Heat from the ground is absorbed into the fluid and then passes through a heat exchanger into the heat pump.

The ground stays at a fairly constant temperature under the surface, so the heat pump can be used throughout the year.

The length of the ground loop depends on the size of your home and the amount of heat you need. Longer loops can draw more heat from the ground, but need more space to be buried in. If space is limited, a vertical borehole can be drilled instead.

Water Source Heat Pumps (WSHP) can be used to provide heating in homes near to rivers, streams and lakes. They extract the heat from open water such as rivers, lakes and canals and can also extract water from sea water.

Maintaining Ground/Water Source Heat Pumps :

GSHP/WSHP require regular scheduled maintenance but you can expect them to operate for 20 years.

There is no need for safety checks for ground source heat pumps and routine maintenance requirements are very low. These may include pre-heating season checks of the water pump, external pipes and fittings and electronics.
