A heat pump is a system that extracts low heat from the ground or air and transfers it at a higher temperature to the hot water or space heating. Typically, well-insulated dwellings are suited best to heat pumps, but in all circumstances, consideration should be given to the choice of system and what requirements are needed of it.
Ground Source Heat Pumps
Ground Source Heat Pumps (GSHP) comprise a heat collection loop containing a non-freezing liquid located underground. This fluid is circulated through the loop collecting heat and is then passed through the proprietary heat pump where the heat is transferred into the space heating system.
Vertical loops lowered into deep boreholes (60-100 m) that are then backfilled with a suitable grout to prevent groundwater migration.
Horizontal ground collection systems that are backfilled with soil.
Air Source Heat Pumps
Air source heat pumps are made up of three main components, these being:
Circulating pump.
Low pressure space heating system.
Proprietary heat pump.
