    Numerous reports of this:
    https://www.bbc.co.uk/news/technology-64939558
    https://datacentrereview.com/2023/03/start-up-uses-data-centre-to-heat-public-swimming-pool/ and of course
    https://www.theguardian.com/business/2023/mar/14/innovative-heat-tech-save-england-swimming-pools-from-closure

    Heating a pool must be the ideal 'target' because the reqd water flow temp is so low; "Pools are just the start and around 30% of all industrial and commercial heat needs could be provided by this technology." sounds a bit un-thermodynamic!

    There are a few swimming pools that have been designed to seriously reduce their energy demands. One or maybe two are PH-certified but I don't remember any details. I think there's a specific set of PH criteria for swimming pools now. Heat pumps are generally used to provide the heat in such designs.

    So making use of waste heat from a data centre to directly heat an existing swimming pool is a reasonable idea, but doesn't really excuse trying to minimise the number of data centres and the efficiency of each one, and increase the efficiency of swimming pools (and then I suppose there's the whole discussion about refurbing existing buildings versus replacing them with new more efficient ones, and I've no idea how that comes out for swimming pools.)

    AFAICT from my local authority, the energy cost argument is just a fig leaf to justify closure/consolidation of leisure centres.

    Like libraries, their main costs are for the staff and buildings, rather than energy, and they are an easier target for cost savings than some other council spending responsibilities.

    New Scientist has an article on a similar setup for domestic heating. Tiny severs heating your water, and fibre connections for data transfer.
