Hot water tanks designed for a solar application should work.
And, depending on your climate, hot water is one of the biggest energy users in the house. So not having to heat your water would lessen the amount of elecricity that would be required in your home thus lessening the output from the engine.

It would work. But you need to be inventive to hook up the plumbing. This is free energy. It all depends on how much effort one wants to put into this kind of project. Need to do a cost benefits analysis as the payback period can be long. This includes solar power, Prius, hybrid cars as the payback period is long, very long.
