A detailed water source heat map has been developed to highlight the opportunities for deploying innovative heat pump technology.

This map identifies the thermal potential of water bodies in England and highlights the presence of existing environmental constraints. It is designed to support local authorities, communities and developers in investigating waterbodies with the best heat potential in their areas of interest.

DECC has developed an interactive water source heat map, which has been incorporated as an additional layer to the existing National Heat Map (now defunct).

The map has assessed local waterbody conditions, such as annual temperature and flow rates of rivers, estuaries, canals and coastal locations in England. Almost all English rivers and estuaries have been analysed for this project.

DECC sees the map being used as a first point of inquiry, prior to commencing any detailed feasibility studies. Users can zoom into the map to investigate waterbodies with the best heat potential in their areas of interest.

Alongside the water source heat map, we have also published a high level customer journey designed to help those interested in installing a water source heat pump.
