Innovative heat tech could save England’s swimming pools from closure

Twenty pools may be upgraded this year after startup uses energy from small data centre to heat water

Public swimming pools facing closure because of soaring energy bills have been offered a lifeline via new technology to heat the water.

Mark Bjornsgaard, the chief executive of the tech startup Deep Green, has trialled the idea in Exmouth, Devon. He has put a small computer data processing centre underneath the pool and the energy from it heats the water.
