A Bitcoiner “pooled” another mining innovation. The “wasted” heat generated by Bitcoin (BTC) mining is used to heat its swimming pool.
Bitcoin enthusiast Jonathan Yuan had kids who “love to swim, but the year before [he started using waste heat], they almost never did because it was always too cold for them. Fortunately, he became interested in bitcoin mining and realized that bitcoin mining emits a lot of heat.
Yuan told Cointelegraph that he bought a “heat exchanger and installed ASICs” (application-specific integrated circuits), and then managed to keep “the pool above 90 F the whole time. ‘summer”.
The process works by immersion, which simultaneously cools the ASICs while “recovering this waste heat and using it for practical applications such as heating living/work spaces, swimming pools or anything that could benefit from ‘heat up to 60°C/140°F”.
However, “when China’s ban happened” and the difficulty adjustment dropped, Yuan made a difficult decision. Should I mine less Bitcoin or turn the pool into a bathtub?
“When [the] the difficulty dropped like a rock, I actually pushed all the ASICs to the limit which brought the pool temperature above 110F so the kids must not have been swimming for about a month or so of them. lol. Yes, I had to say “sorry kids, the pool is too hot, you can’t swim today””
The difficulty adjustment has since reached new heights and his children are able to swim again. Additionally, Yuan “made money” from mining and, interestingly, “the best part is that the pool acted as a perfect thermal buffer.”
In fact, using Bitcoin miners to heat your pool is more efficient than traditional methods: it keeps “temperature variations over a 24-hour period to just 1F to 2F despite ambient temperatures exceeding 40F on some days.”
Based in Minnesota, in the upper Midwest of the United States, Yuan kept the pool “warm” even in cold weather:

Yuan recommends anyone with a swimming pool do the same, as it’s the “perfect use case scenario” for waste heat. With his home mining setup running smoothly, Yuan is now building a pool-specific tank that will be designed to run pool water directly through the heat exchanger.
ASICs now heat Yuan’s house, and he has turned a passion project into a profession. His bitcoin mining company, CoinHeated, is “dedicated to turning waste heat from bitcoin miners into productive heat.”
The plan now is to bring pool heating projects to other homes, and he’s in talks with “heat exchanger manufacturers who will be able to make something that won’t corrode with treated pool water. chemically”.
In the meantime, the children can enjoy the swimming pool of his house, heated thanks to Proof of Work.
Here are some kids enjoying the nice hot pool. I don’t swim there myself. Not really into swimming. pic.twitter.com/MHRW86D6Me
