Heat Absorbed from the Ground
Ground source heat pumps use pipes which are buried in the garden to extract heat from the ground.
Much like air source heat pumps, this heat can then be used to heat radiators, underfloor or warm air heating systems and hot water in your home.
A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe – called a ground loop – which is buried in your garden.
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 – even in the middle of winter.
(Note the picture shows a commercial system and a domestic one would be smaller in size).
Ground Source Heat Pump systems will leave you with the following benefits:
- Could lower your fuel bills, especially if you are replacing conventional electric heating.
- Could provide you with an income through the government’s Renewable Heat Incentive (RHI).
- Could lower your home’s carbon emissions, depending on which fuel you are replacing.
- Don’t need fuel deliveries.
- Can heat your home and provide and hot water.
- Need little maintenance – they’re called ‘fit and forget’ technologies.
