OK so the score is 5 for turning it off and 0 for leaving it on, and I think 3 for thread hijacking

. I really thought at least someone would go the other way. Have you ever gone out and watched your electric meter spin off the house when you turn on the 220V to the water heater? It takes a considerable amount of time (hours) and energy to heat the cold water in the tank. Once it is hot and not being used I would think it would take much less energy to occasionally turn on the one element. Kind of like the theory that turning your lights on and off at night when you enter a room actually uses more energy than leaving it on. I guess I'll take my bat and ball and go home now......
Thanks everyone....
