What about using the wasted electricity to heat your shower water? Or to cook?

How would one do this?

Easy enough with a GPU, harder for an ASIC as you would need a custom water cooling block for the ASIC.

With a GPU, you just pop on a water cooling block in place of the air cooled heatsink. You would need to have a hot water tank with an indirect heating coil. Essentially that is just a coil of copper pipe that is inside the hot water tank and the ends of that coil are external to the tank. You would rig a pump to pump the hot water coming off the GPU into one end of the coil and then rig up a return pipe to take the water coming out of the other end of the coil and run it back into the GPU cooling block. When you start out with a tank full of cold water, the water coming back out of the coil will be cold and will go straight back into the GPU. Over time, as you heat up the water in the tank, you will see that the temperature of the water coming out of the coil will warm up and eventually be too hot to be fed back into the GPU. So, you will need one other component in the system, a water/air radiator in the line between the coil exit and the GPU input so that you can still cool the GPU even when the water in the tank is hot.

OK, but scalding water is like 42C, brisk for a GPU and acceptable for an ASIC. Your hot water regulator could be a computer-controlled diverter valve with a fan and radiator (heated air for the winter, could just be exhausted in the summer) to keep it in that range.
