A ground source heat pump is a low-carbon way of heating your home. They absorb latent heat from the ground, via either bore holes or ground loops and use it to increase the temperature inside your home. Their size depends on how much heat they'll need to generate for your home - the more heat, the bigger the heat pump.

Ground source heat pumps are usually positioned indoors with an external connection to ground loops or boreholes. You'll usually have a unit containing pumps, buffer, and hot water cylinder. You won't normally need planning permission for an air source heat pump, but if you live in a listed building or conservation area, then you'll usually need the consent of your local authority. Also check that your installation will meet the building regulations in your area. Speak to your home insurance provider too to check if your policy will cover the changes to your heating system.

You'll either need a plot of land with space forground loops, or an accessible and suitable area where boreholes can be dug.Internally, a plant room would be preferable to house all the kit and keep it accessible for servicing, most internal units will have servicing clearances depending on manufacturer. Certain manufacturers also supply GSHP’s with abuilt in hot water cylinder, pumps and heat exchanger for space saving

Ground source heat pumps make very little noise,they have been compared to the sound level of a fridge.
