Ground Source Heat Pumps
Ground source heat pumps use the inexhaustible energy stored in the ground, a buried ground loop or bore hole is used to transfers heat from the ground into a building to provide space heating and, in some cases, to pre-heat domestic hot water.
How it works
In the same way that your fridge uses refrigerant to extract heat from the inside, keeping your food cool, a ground source heat pump extracts heat from the ground, and uses it to heat your home. A ground source heat pump system has three main parts:- The Ground Loop - Usually a sealed pipe loop buried in the ground by means of a bore hole or horizontal trench
- The heat pump unit – Sized accordingly to suit the system which incorporates the refrigerant cycle components required to generate the heat required
- The heat distribution circuit– Usually in the form of underfloor heating or traditional radiators for heating, for domestic hot water a traditional storage cylinder can be used.
The Benefits
- Consistent ground temperatures through the year offer a highly efficient heating system up to 4.5 times that of a traditional heating system.
- Greatly reduced carbon emission.
- Reduced reliance on fossil fuels makes it a good all round solution for rural properties.
- Can be used for cooling or heating when using fan convectors or underfloor heating as the emitter source.
Restrictions
The main restriction to fitting a ground source heat pump is the land space available to install the ground collector loop. To find out if your property is suitable for a ground source heat pump visit our FAQ section or contact us for a no obligation site survey
