Adding electric heat element to gas water heater

[TurnThePage]

Because my old travel trailer may need to be permanently occupied for the next 6 months or so, I'm considering adding an electric heating element to the gas only water heater. The tank is aluminum, and it looks like the available kits use brass fittings. I'm concerned about galvanic corrosion. Anybody have experience with these things?

On one of my gas only water heaters I added a hot ROD I think it was called.
worked but a bit slow.

Not with the kits, but yes Aluminum and Brass will set up a galvanic cell. Putting a insulating gasket in between the brass fitting and the tank may prevent the corrosion. A piece of teflon or rubber would work.
