Exmouth Leisure Centre in Devon is the first UK site to benefit from free heat supplied by British tech start-up, Deep Green’s, heat-recapture cloud technology.
Deep Green’s ‘digital boiler’ technology is a cloud data centre that uses ‘immersion cooling’ to capture heat from the operating data servers and transferring it into a site’s existing hot water system free of charge.

Launched yesterday (14 March) the public swimming pool is the first UK site to benefit from free re-captured heat. The 12-server installation is expected to reduce the pool’s gas requirements by 62%, generating savings of over £20,000 a year.
Peter Gilpin, CEO of LED Community Leisure (operator of Exmouth Leisure Centre), commented: “Deep Green’s innovative technology will dramatically reduce our energy bills and carbon footprint, meaning we will continue to be a key asset for the local community. We are already seeing the benefit. I’m certain this will transform leisure centres up and down the country for the better.”
Leading on from Exmouth, Deep Green has announced further installations in Bristol and Manchester over the coming weeks.
The start-up has also identified over 1,500 pools in England that could benefit from free heat re-captured by its technology to help leisure centres tackle rising energy costs.
Overall, Deep Green claims that 30% of industrial and commercial heating requirements could be provided by its technology.
“Data is critical to modern society and demand for data centres is growing exponentially. However, this comes at a cost. Current data centre infrastructure is inefficient, using a huge amount of energy and generating a vast amount of waste heat. Yet, at the same time, there are many businesses that need heat and face increasing energy bills,” said CEO of Deep Green, Mark Bjornsgaard.
“By moving data centres from industrial warehouses into the hearts of communities, our ‘digital boilers’ put waste heat to good use, saving local businesses thousands of pounds on energy bills and reducing their carbon footprint. Pools are just the start and around 30% of all industrial and commercial heat needs could be provided by this technology.
“Organisations that are serious about supporting society and reducing their carbon emissions should not forget the massive impact of their computing needs. Deep Green now provides an answer.”
