Advise given to me from a plumber
I'll pass along some advice a plumber gave to me: I mentioned that I was going to turn my gas hot water heater off while I was away, since it made no sense to me to pay to heat water I wasn't using. The plumber advised against this. He said its better to turn the hot water heater DOWN, than to turn it off completely. He said that if you turn your hot water heater totally off, all kinds of scum starts to grow in your tank. He said it was better to keep it running at a low setting. And look to see if your hot water heater has a vacation mode. Hope this helps.
