Understanding Ground Source Heat Pumps
Heat your home or business from the ground
How does a ground source heat pump work?
Heat from the ground is absorbed at low temperatures into a fluid inside a loop of pipe (a ground loop) buried underground. The fluid then passes through a compressor that raises it to a higher temperature, which can then heat water for the heating and hot water circuits of the house. The cooled ground-loop fluid passes back into the ground where it absorbs further energy from the ground in a continuous process as long as heating is required. The heat pump requires electricity to run, but uses far less electrical energy thus saving you money in the long run. The heat pump performs the same role as a boiler does in a central heating system, but it uses ambient heat from the ground rather than burning fuel to generate heat.
Benefits of ground source heat pump?
- Can reduce you carbon footprint: heat pumps can lower your home’s carbon emissions, depending on which fuel you are replacing.
Costs of installing a typical system range from about £11,000 to £15,000. Running costs will depend on a number of factors – including the size of your home and how well it is insulated.
Savings will vary depending on many factors, some are outlined below. It is important that the system is controlled appropriately for your needs.
Domestic or commercial options
Rexel Energy Solutions can supply a range of single and three phase heat pump models from DimplexAll can provide hot water flow temperatures of up to 70°C.
What savings can be made?
Servicing and maintenance
You can expect a Ground Source Heat Pump to operate for 20 years or more, but they do require regular scheduled maintenance. A yearly check by you and a more detailed check by a professional installer every three to five years should be sufficient. The installer should leave written details of any maintenance checks you should undertake to ensure everything is working properly.
