Service Description: A district heat network is a system of insulated pipes that delivers heat from a central source (an energy centre) to multiple buildings for space heating and hot water. Instead of each building having its own boiler or heat pump, heat is produced or recovered centrally and distributed as hot water or steam. This layer shows existing (operational) district heat networks (line features only) for schemes that have been shared with the Greater London Authority.
Whilst every effort has been made to ensure the quality and accuracy of the data, the Greater London Authority is not responsible for any inaccuracies, omissions or mistakes in the information provided.
The mapped data and associated information is indicative and intended only for general reference. It should not be used for detailed engineering, design, or other applications that require precise accuracy.
