Bolton homes to be warmed from waste sewer heat

The UK Government is providing £80.6mln to develop 'low-cost heating systems' in four new projects in England.

Nearly 2,000 homes and businesses in Bolton are to be powered by excess heat taken from sewers, according to the Department for Energy Security and Net Zero.

Energy will be extracted from both sewage and waste hot water to fuel a new heat pump, as part of Bolton's first district heating network.

The other three projects to receive a share of the funding are:

• The Exeter Energy Network will use air source heat pumps and the UK's largest, high-temperature, water-source heat pump. Connected buildings are forecast to reduce carbon emissions by 65%-75%.
• The Hull East District Heat Network aims to provide low-carbon heating to 14 public sector council buildings and industrial businesses.
• Lastly, the Greenwhich Peninsula ESCO District Heating Network in London will connect more than 9,000 existing and new homes, and heat more than 94,000m² of commercial space.
