[Christ]

Um... this is a great idea... and I'm not sure how it compares, but my dad takes a shower at the same time every day... and he uses a timer to make sure that there is enough hot water to take his shower each day.

When he gets home from work up to 14 hours later, the water is usually still warm enough to wash your hands, etc.

Electric - 30 Gal. Bought last year.

If I were using a gas water heater, I'd consider trying this out. If he decides to go back to gas (he's been talking about it) I'll have him try it. He doesn't like the idea of a pilot light, though, which is the only reason he's not gone back to gas.
