Well, we in NW OH have to remove our anode rod in any new water heater hear due to high minerals make our water stinky. I have never had to replace a water heater due to corrosion, so I don't think this would be a problem. As for the wire deal, I don't see it being a big deal, just to run a few wires, and wire up an electric switch beside my gas switch...anyone with some experiance with these????
