Developed by the , it is a publicly accessible resource providing high-resolution maps of heat demand across England.

It aims to help local authorities and community groups identify locations where heat distribution projects are most likely to make a difference, through cutting carbon emissions and reducing heating costs.

The content for the map and the core of the system is delivered entirely across one of cloud provider Memset's Miniserver VM Virtual machines, whilst the heat layer images are being stored on Memset's cloud storage solution, Memstore.

Soon after the map's launch there was a peak of nine million requests per hour, which caused a minor lag issue for the service. However, Memset's agile team wrote, tested and deployed a performance enhancement patch on the same afternoon that solved the problem.

"The National Heat Map represents a big step forward in the use of the web to provide intelligence and support for the development of local energy projects," said CSE's head of research and analysis, Joshua Thumim.
