It doesn't have to be competitive.

4+ kWh electric showers are ubiquitous in my country. Literally a dumb piece of metal resistance immersed in water. Anything is better than the current situation. What if it was a processor instead?

What if a bunch of home servers could heat up stored water through their heat instead of just dissipating that energy uselessly into the air?

We'd be getting the heat we need and we'd be helping build a decentralized cash network. We were gonna spend energy heating up stuff anyway. Might as well get some cryptocurrency out of that heat.

This is what WiseMining.io is addressing with their Sato “bitcoin boiler.” It uses hashcards (daughterboards populated with mining ASICs) immersed in coolant to augment a typical heat pump setup.

That's interesting. My search for products in this category turned up the Qarnot company which also has a "digital boiler". Apparently, it's a general purpose Linux server that can be used to mine any coin or perform any type of computation.

Not sure if it's even available outside Europe. I wonder if it's possible to somehow replicate this with a home server. How is it pumping the heat out of the components and into the water system?

A datacenter that doubles as district heating seems like a pretty good idea.
