I'm not going to be any help to you here, but I have been pondering the water heater question myself. Mine is working fine, but it is a senior citizen in water heater years and I like to plan ahead. I turned it down to 120 degrees and left it there. We always run it dry and I fear I am wasting more energy than if the water was hotter and we only used half the tank. Do you have any insight on the subject?
