Homes in north London are set to be heated by warm air from the London Underground
A joint project between public bodies and an engineering firm will heat 1,000 homes in Islington by the end of 2019, thanks to a 1MW heat pump recycling hot air from a ventilation shaft and transferring it to the hot water network.
Air in the underground is pumped out at 18-28 degrees. The Greater London Authority estimates that the heat wasted in London is enough to supply 38 per cent of the city’s heat demands.
