Ground source heat pump systems
The ground source heat pump is slightly more efficient than the air source heat pump, but a more demanding installation. A network of pipes are buried approximately 1.2 metres deep to extract gentle heat from the ground. Ground source heat pumps can provide up to 55°c temperatures. As with all heat pumps, they are more economical when running at lower temperatures. If you have the space and you don’t mind if we dig some trenches, then ground source heat pumps can offer significant savings on running costs compared to a boiler and a benefit over air source heating.
The cost of installation is about double that of an air source heat pump installation, with about a 10% efficiency gain.
