Ground source heat pumps extract heat from the ground using pipes which are buried in the garden. This can then be used to heat radiators, underfloor or warm air heating systems and hot water.
The ground’s heat is absorbed into a mixture of water and antifreeze which then passes through a heat exchanger into a heat pump which can be used throughout the year – the ground remains at a fairly constant temperature all-year-round.
Ground loops of varying lengths can be installed, depending on the space available and the amount of heat you need for your home. Where space is limited, a vertical borehole can be drilled.
Heat pumps deliver heat at low temperatures but over much longer periods, so would need to stay on permanently throughout the winter months in order to maintain a constant heat. Users can expect cost savings, the scale of which would depend on a number of factors including the type of heat distribution system, current fuel costs, efficiency of the old system, whether the system is being used to heat water and effective use of the system’s controls.
Benefits of Ground Source Heat Pumps
- Lower fuel bills, particularly than conventional electric heating
- Provides an income through the government’s Renewable Heat Incentive (RHI)
- Lower carbon emissions
- Little maintenance required
