Computation and resistive heat are pretty much the same in efficiency. Heat pumps, which will pump outside heat inside, are a lot more efficient. So, "computation for heat" is only useful to the point that it's replacing a space heater or other resistive heat, or is focused in a place resulting other heat use by a lot. So, my computer could be a cost-effective way to keep my feet cozy. This also presumes that cryptomining is "useful computation".
