My Father's got an electric water heater that runs for 1 hour once a day, on a timer. It ran at noon yesterday, and still had hot water when I left at 1AM this morning. There is no tank blanket or anything... it's just a normal water heater. I think that's pretty good, especially considering that it's on a concrete floor in the root cellar/back room area, which isn't heated.
I find that pretty impressive.
