I've heard the idea before about turning it off nightly with a timer, but it strikes me as questionable whether it'll save very much, since maintaining a temperature is less intensive than bringing the water up to the desired temperature. Now if you were going away for a week or more, I'd say definitely turn it off for that time. But nightly, I just don't know if it's worth it. Don't know how to calculate that, either, I'm afraid.

To begin with, gas heaters are much more efficient - Sir Four
