Underground line to heat up London homes during winter

Scheme to pipe 'waste heat' from tube into hundreds of Islington homes and businesses

The sweltering temperatures on the tube's Northern line will soon begin keeping homes in Islington, north London, cosy through the colder months, under a scheme to harness the heat from the underground.

By the end of the year the project will pipe heat from the underground into hundreds of homes and businesses that are part of a heating scheme in the borough.
