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.

Fed up with negative news? Can you help us?

The negativity bias in the media is holding society back. While it’s important to report problems and hold power to account, we believe there is also a need for rigorous reporting on progress, possibility and solutions. We call this ‘constructive journalism’, and to keep doing it we need your help.

We know you want Positive News to benefit as many people as possible, so we haven’t put up a paywall. We don’t answer to and rely on a wealthy proprietor because, instead, we are owned co-operatively by 1,500 of our readers who joined our crowdfund in 2015. And we’re not beholden to advertisers either, because we know that you only want to hear about companies that have a positive impact.

So, instead, we depend on you. Positive News is more than a magazine, it’s a community of people who see and share the good in the world. We need your support to continue publishing our inspiring journalism and to set the example for other media to follow. It’s quick and easy to contribute and you can support Positive News from just £1. Every contribution makes a vital difference. Thank you for helping us to change the news for good.
