You did explain it well, I was commenting on the statement that Kory made which was "Only the bottom portion of the insulation on both upper and lower was wet." and nothing about water or moisture or rust anywhere else.
Even if there were rust all over, I would doubt the condensation theory as, with the water off, the water heater drained for winterization, and no power on the elements, and with insulation on the inside the outer tank covering, what is to cause condensation, unless on the *outside* of the outer housing?
I may be missing something here, but condensation typically collects on the cooler surface, and the outer covering would be cooler on the outside of it. If any condensation were to occur inside the outer covering, I would think that would be on the metal tank itself, which would not show rust through the outer covering anyway.
Where is my thinking going wrong?
And if the tank was insulated with that foam and not fiberglass, I doubt there would be any condensation on the outside of the tank anyway. Any condensate would be on the inside of the tank, and that is intended to have water in it.
