Underground Lines To Heat Up North London Homes

Heat from London Underground tunnels will be used to keep homes in Islington warm under a new scheme, it is a joint project between Islington Council, TfL and engineering firm Ramboll. Warm air from a disused Northern Line station will support a heat network supplying up to 1,000 homes and businesses by the end of the year.
