Is a large ground source heat pump suitable for your site?

British Geological Survey launches online tool which screens initial suitability of any site in England and Wales for a large ground source heat pump

The British Geological Survey in collaboration with the Environment Agency has launched a free tool to assess the ground suitability to install large (>100 kilowatts) ground source heat pumps (GSHP). Users can identify favourable locations for an open-loop GSHP scheme by identifying their locations on the map. The maps provide information such as presence of an aquifer beneath the site or the size of licensed groundwater abstractions in the vicinity.  More than 10 national datasets which influence the feasibility of large open-loop GSHP schemes have been incorporated into the web-based GIS tool.

The screening tool does not provide definitive answers, and designers will still have to obtain more detailed, site-specific information to prove the hydrogeological and economic viability of a scheme at a specific site. 

John Findlay, Director of Carbon Zero Consulting, said ‘This new tool will be useful for identifying viable open loop locations at an early project stage.  More generally the tool shows that favourable conditions for the installation and running of open-loop systems exist in large parts of the country’.

Further information, and the tool itself, is available here.

Should RIBA have an annual sustainability award?
