Where can I buy a compute-for-heat home system?

Edit: I have a heat pump, which is more efficient for heating of course

A late model Intel MacBook from eBay and pretty much any Electron app from 2020 should do it.

I remember some startups trying to install cryptominers in people homes, the idea was to use the electricity that would be spent heating the space anyways. The company would pay for the mining hardware while the customer would provide the electricity, and the profits would be shared.

I don't know how it worked out, but the idea was there.

		I know of this one [1], a 1000W space heater with integrated cryptominer. Looks kike you can actually buy it now. Not sure how much the mined crypto offsets the heating costs though. [1] https://21energy.com/products/ofen-2

You might prefer a heat pump.

I do and have one actually. I have no idea if a kWh of compute could be worth more than eg. a kWh/(heat pump COP) though. Probably not...

		My understanding is that for most residential heat pumps, the temperature needed to make the heat pump less efficient than resistive heating is so low that it enters a range that the pump doesn't even work anymore. However, that's only a measure of efficiency. It could still be that the throughput isn't enough. A 30 kW resistive heater can ALWAYS output 30 kW of heat. But my 7 kW heat pump could produce anywhere from 14 to 30 kW depending on outside temperature.
