The term ‘ground source heat pump’ (GSHP) refers to a buried network of fluid-filled pipes that are connected to a compressor and pump unit to provide heating for buildings. GSHPs offer less carbon emissions, lower running costs and greater efficiency than gas boilers.

This audio explainer explores how GSHPs work, the application of them in both domestic and larger-scale settings, and the potential future of the solution.
