About Ground Source Heat Pumps

The ground source heat pumps technology converts the thermal energy stored in the ground into heat, which in turn heats your hot water and heating system in a very efficient way.

They can be extremely beneficial in cutting your energy bills and your carbon footprint. With rising fuel bills that has got to be a major consideration and by installing a Ground Source Heat Pump you will be going a long way to helping to save our environment too. Talk to us to find out if you can earn revenue through the RHI scheme & reduce your home’s energy consumption.

How do Ground Source Heat Pumps work?

Ground Source Heat Pumps systems are made using loops of water pipes, which are buried in the ground. The heat pump harnesses natural heat from the ground by pumping a mixture of glycol (antifreeze) and water around the ground loop absorbing the natural heat. The mixture is compressed and passes through the heat exchanger. Basically it extracts the heat and transfers it into the heat pump, which increases the temperature.

The heat pump then transfers it into your heating system, for hot water, through radiators, or into an under floor heating system. A ground source heat pump does need electricity to run but will use less electrical energy by using the heat the ground produces. In effect the heat pump is acting as your boiler and the ground is providing heat rather than burning fuel.

Do you need planning permission for a ground source heat pump?

The installation of a ground source heat pump or a water source heat pump on domestic premises is usually considered to be permitted development, not needing an application for planning permission.

If you live in a listed building or a conservation area you should contact your council to check on local requirements.

Can I get a grant for a ground source heat pump?

Ground Source Heat Pumps – Up To £31,500 Grant Available

With the government grants that are available through the Renewable Heat Incentive the install costs can partially or fully recouped. Finance can also be provided for UK residents as well as interest free loans through the Energy Saving Trust. Grants are only available for a new installation, a Grant cannot be applied retrospectively for existing equipment.

How are ground source heat pumps installed?

It depends on whether you have a horizontal or a vertical array, and this will depend on the space available and your ground conditions:

  • A horizontal array consists of a pipe laid in a serpentine closed loop in a trench, usually 1.2m deep. You will need a fairly large garden — allow 500m² for a 10kW heat pump in clay soil, and twice that for sandy soil. Pipes can be a straight pipe or in coils, called a ‘slinky’ pipe.
  • A vertical array, often called a borehole system, will have boreholes drilled into the ground and connected across their tops, in a closed loop. The number and depth of boreholes will be dictated by the size of the heat pump and the geology. For instance, a 8kW heat pump is likely to need at least three boreholes 70m to 100m deep (or two slightly deeper boreholes). They do not need a large area of land and if the price is right, a vertical array is a good option.

Is a ground source heat pump right for my home?

If you are considering a ground source heat pump, bear in mind:

  • A heat pump works best in a well-insulated home. A home with a high heat demand will need a larger system which will be expensive to buy and install, and very expensive to run
  • A horizontal array needs enough garden space. That said, a borehole installation is an option for those short on space. You will also need to consider access to the site for excavation machinery
  • It will need to be paired with a suitable heating system and is most efficiently paired with underfloor heating as this requires much lower water temperatures than radiators.
