Ambient Temperature
I looked at the link about all the math behind turning off the hot water heater. It looked like the assumption was that it was 60 degrees in the room in which the hot water heater was located. In my case, the heater is under the house, exposed to outside air temperatures. This week that can go down into the 30's. I would think the savings are much greater turning it off instead of the heater keeping the water at 120 degrees while we are not there.
