National Heat Map


The National Heat Map supports the planning and deployment of local low-carbon energy projects in England. It aims to achieve this by providing publicly accessible, high-resolution, web-based maps of heat demand by area. The map can be used to explore suitable locations for district heating by helping to identify places where heat distribution is most likely to be beneficial and economic. It can also be used for finding potential sites for water source heat pumps that could provide over six gigawatts of low-carbon heat to communities.

The uniqueness of the National Heat Map lies in its detailed address-level modelling of demand data and the tools for analysing this. The original heat-demand map was built for DECC by the Centre for Sustainable Energy (CSE) in 2010, and has recently been expanded and improved with the addition of four 'water source heat potential' layers featuring 4,000 rivers, estuaries, canals and coastal sites across England. The heat map combines a very detailed geographic model of energy use with a range of user-friendly visualisation and reporting tools, providing sophisticated GIS functionality to non-technical users via a standard web-browser.
