Underground to Heat Homes

The Bunhill station has been out of use for more than 100years. It is now being turned into a new energy center with the potential to heat 1,350 homes a school and a leisure center; through waste energy.

The station uses heat that would otherwise go to waste, it is estimated that it will help to reduce CO2 emissions by around 500 tonnes each year.

It will also cut the heating bills for council tenants who are connected to the network by around 10%.

Bunhill is being turned into a place to house a huge underground fan that extracts warm air from the Northern Line. This air then travels through a series of 1.5km of pipes, heating water which is then used for domestic and commercial heating systems.

Andy Lord, managing director of the London Underground, said: ‘Capturing waste heat from Tube tunnels and using it to supply heating and hot water to thousands of local homes hasn’t been done anywhere in the world before so this ground-breaking partnership with Islington Council is a really important step.
