This is a new one on me. Hopefully someone else has some thoughts what to look for. In the recent freeze, we lost hot water. It froze so fast didn't even get a chance to do all the prevention steps. But when it thawed, there seem to be no busted or cracked pipes. Yet there is no hot water. We've gone through the big 3: changed breaker, drained heater and added new elements, and today bought new thermostats. Still nothing. I'm stumped. Is there even a fourth thing? Could it have anything to do with the heavy iron content of our well water? Please any help is appreciated. Been without hot water 4 days now and dishes are piling. TIA
