The Bunhill heat network supplies cheaper, greener heat to over 800 homes in Bunhill ward, as well as Finsbury Leisure Centre, Ironmonger Row Baths and offices on Old Street. The network will grow organically as new buildings built in the area are connected.
Launched in November 2012, the heat network is fed by the local energy centre on Central Street which produces both electricity and heat in a combined heat and power plant. The energy centre uses the heat created from producing electricity to create hot water that is piped into people’s homes, making it more efficient than a normal power station, for which the heat is a waste product.
Phase 2 of the Bunhill Heat and Power network involves building a new energy centre at the top of Central Street, connecting the King’s Square Estate to the network and adding capacity to supply a further 1,000 homes.
The core of the new energy centre is a 1MW heat pump that will recycle the otherwise wasted heat from a ventilation shaft on the Northern Line of the London Underground network, and will transfer that heat into the hot water network. During the summer months, the system will be reversed to inject cool air into the tube tunnels.
Works and road closures
Colloide Engineering Systems Ltd were appointed by the council as its contractor for these works. They have installed pipework under Central Street, Moreland Street, Lever Street and President Street to allow the connection of the network to President House, Rahere House, Barnabas House and Macclesfield House.
Energy Centre 2 site
Part of the works around the Energy Centre was the completion of the new ventilation shaft by TfL. Colloide are now carrying out work on the new building adjacent to Kestrel House.
Access from Central Street on to City Road will remain closed while these works take place and the eastbound lane of Moreland Street between Pickard Street and Central Street will be closed until February 2019. Moreland Street will be fully closed during brief periods in September 2018 when cranes are used to erect part of the new energy centre structure.
King’s Square Estate
Works will also be taking place on the King’s Square Estate during September 2018 to finalise the connection between the heat network and the buildings.
