I’ve seen a video of at least one spa that does that. They mine bitcoin on rigs immersed in mineral oil, with a heat exchanger to the spa’s water system. I’m struggling to imagine that’s enough heat, especially piped a distance through the building, to run several hot tubs, and I’m kind of dubious about that particular load, but hey.
A large data centre can use over 100 MW at the high end. Certainly enough to power a swimming pool or three. In fact swimming pools are normally measured in kW not MW.

“A large data centre” this wasn’t. I saw a couple washing machine-sized vats of oil-soaked computers.
If all it’s running is a hot tub that sounds reasonable. This bitcoin miner uses over 3kW: https://www.aozhiminer.com/showroom/high-profit-110th-95th-bitmain-antminer-s19-pro-s19-bitcoin-miner-with-power-supply.html
