Free Data-Center Heat Is Allegedly Saving a Struggling Public Pool K a Year
An anonymous reader quotes a report from Ars Technica: A public pool in the UK is expected to save [about $24,000] and cut carbon emissions by 25.8 tons annually by warming a 25-meter children’s pool with waste heat from a data center from startup Deep Green. UK-based Deep Green is a newcomer in the data-center heat game and is making its entrance notable by putting a monetary figure on potential savings, which are fueled by the heat’s low, low rate of free. Deep Green’s paying customers are machine-learning and AI firms seeking computing resources. As reported by Datacenter Dynamics on Tuesday, clients can leverage Deep Green’s 28 kW system with high-performance computing (HPC) capabilities. The HPC cluster at the Exmouth Leisure Centre swimming pool has 12 four-CPU cards and could eventually be used for cloud services and video rendering, Deep Green CEO Mark Bjornsgaard told the publication. According to the BBC , the server is about the size of a washing machine.

The computers are submerged in mineral oil that captures heat that gets transferred into pool water with a heat exchanger. The pool still has a gas boiler to boost the water’s temperature if required. Deep Green claims it’s transferring about 96 percent of the energy used by its computers and reducing a pool’s gas heat usage by 62 percent. Deep Green is paying the Exmouth Leisure Centre for all the electricity its data center uses, as well as any setup costs, and the Exmouth Leisure Centre gets the heat for free.

Deep Green CTO Mat Craggs told Datacenter Dynamics: “Our expected heat transfer from the kit is 139,284 kWh a year, equivalent to 62 percent of the pool’s heat needs.” He noted that adding more servers to the tub could extend the figure to 70 or 80 percent. Deep Green’s data center can heat the Exmouth Leisure Centre’s 25 meter pool to 86 degrees Fahrenheit for about 60 percent of the time, BBC reported. The startup has plans to set up data centers in seven more UK locations and has a 2023 target of 20 locations.
