Ground Source Heat Pump

What is it?

Ground Source Heat pumps use pipes underground to extract the heat from the ground. This is then harnessed to heat radiators and the heating systems in your home. It can also be used for your hot water.

How it works?

The heat in the ground is absorbed into a fluid that runs inside loops of pipe buried underground. The fluid is then compressed to increase the temperature and this higher temperature is transferred to your house’s heating and hot water systems. Once the heat from the fluid has been used, the cooled fluid flows back to the pipes in the ground to absorb more heat. This is a continuous process.

Ground Source heat pumps are normally laid in trenches between 0.8m and 2m deep. If there is not enough room for trenches then a borehole is normally dug up to 100m.

What are the benefits?

  • Can reduce your fuel bills – especially when replacing electric heaters.
  • Can lower your homes carbon emissions
  • Ideal in areas where you have a lot of ground and no direct fuel supply

How much does it cost?

This depends on the size of your property and the system you require. Typical systems range from £8,000 to £16,000.

How much can I earn?

The Governments RHI (Renewable Heat Incentive) will launch in summer 2013.

This means that you could receive money for lowering your carbon emissions.

What are the next steps?

You need to think if your ground is suitable for digging trenches or boreholes and if there is access for digging machinery.

Another factor to consider is how energy efficient your home is. If your house is well insulated and free from draughts, the system will be more efficient.
