atwood g6a-8e

My aluminum tank burst and nobody near me will even attempt to weld it. I found a post where someone recommended I contact an airstream dealer and give part #690199 for a water heater replacement. It pulls up the dometic aluminum replacement since the atwood tank is no longer available.

My issue is, that model is equipped with a 3 prong plug and mine is wired. There is not an electrical outlet in the compartment. Does anyone have a part number for the water heater that replaces g6a-8e that is wired and doesn't require an outlet in the compartment?

Better yet, does anyone have an Atwood g6a-8e supplier? Perhaps an RV salvage yard or contact with someone who may be able to find me one?

Thanks!

First, replacement tanks are (were) available for these aluminum tanks. I'd spend some time searching for one. They are not cheap, but if the rest of your water heater is in good condition it will save you from having to make any modifications to fit the newer one in place of the old.

Second, if your original was hardwired then you can certainly hardwire the new one. Or you can install an outlet where the old one was hardwired. These are simple changes that any electrician can make in a short time if you're not comfortable doing electrical work.

If you do go with the newer model, there are kits available to allow you to continue using the existing opening and outer door. The only issue I've read about is the possibility of not having enough clearance behind the water heater, as the new ones go deeper into the trailer.

Sadly the old Atwood unit has been discontinued.
Suburban has a direct fit replacement unit for the Atwood with similar dimensions. The new Dometic version has different dimensions.
Here is a link to the replacement.

If my memory is correct, the Suburban unit uses a steel tank and not aluminum. Not a deal breaker, but for me the aluminum is much better and more long-lasting.

The Dometic unit is essentially the same but with a slightly different form factor.

The new Dometic water heater is a different dimension length, width and height. Sometimes they are to deep for the cabinet in which they are installed and of course the Airstream skin must be modified to fit the new cabinet size. There is no way a new Dometic would fit in the cabinet in my 1994 Classic. Any modification of the cabinet for the space that would be needed to use the Dometic would likely make the toilet unusable.

It is much easier to use the Suburban with a glass lined steel tank - just like many home water heaters. Tank anodes are easy to replace. I agree the aluminum tank would be nicer. This was a bad move by Dometic. Several of my white box friends have had the Suburban water heaters without issue.

I am in the process of replacing the old Atwood with a new Domestic. Big changes. More or less on my third week of a 2 day job. Door kit to cover up the overly large hole. Cut away part of the cabinet under the twin bed. Extend and reshape the gas line. Cut a new hole for the switch in the bathroom. The Suburban would have required re doing the cabinet and the gas line also. Plus the Suburban is a good bit heavier.

Bill, how did your conversion turn out. Any photo's of the process and finished install you could share?


Thanks!
