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 transfer 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 emissions.

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.
