THOUSANDS of Islington homes will be heated by hot air from the Northern line after the ribbon was cut at a world-first energy centre.
Hot air from the underground heats water which will soon be pumped to more than 1,350 homes, a school and two leisure centres, reducing heating bills and carbon emissions.
The new energy centre has been built above the old City Road underground station, where a huge underground fan pumps up the waste air from the tunnels.
It is then used to heat water which is pumped through 1.5 kilometres of pipes to reach its destination.
Known as Bunhill 2, the project adds 550 homes and a primary school to the existing network, which was launched in 2012.
The underground fan can also be reversed, meaning cold air could be pumped into cool the tube system.

London Mayor Sadiq Khan said: “If we’re truly going to tackle the climate emergency we will need progressive partnerships between local authorities, City Hall, TfL and others as was demonstrated so perfectly by this project.”
Islington’s environment chief, Labour councillor Rowenna Champion, said: “This pioneering project recycles heat that was simply being lost to the environment. We are cutting carbon emissions in a way that also reduces people’s energy bills, helping us to help them at a time when the cost of living is soaring.
“This initiative also helps to reduce fuel poverty and make Islington a fairer place, while offering our communities a sustainable, cheaper and greener future.
“I’m very proud of this exciting project, which promises to make a real difference to residents and the environment.”
