The Bristol heat network in detail

Existing network and proposed connections

in 2019, Bristol City Council commissioned 'Bristol net zero by 2030: The evidence base' by the Centre for Sustainable Energy. This report indicated a heat network could potentially deliver zero carbon heat to up to 62,000 residential buildings and 6,000 commercial buildings in the city. 

In response to this, the council focussed on developing heat networks in high heat demand areas, such as central Bristol, which then led to the creation of the Bristol heat network.

Bristol has England's largest water source heat pump at Castle Park. This facility uses electricity from renewable sources to extract heat from the floating harbour before pumping it to nearby homes and businesses. As the network grows, it will be increasingly reliant on low carbon sources of heat. 

The network now supplies heat for space heating and hot water to many buildings, businesses and residents in Redcliffe and Old Market, and is being extended to Bedminster and the Temple area with possible routes to connect these areas together to be explored.

Feasibility studies have also been carried out into other potential network areas in Ashton Gate, City Centre, Frome Gateway and Spike Island.
