Hey all, Id like to replace my Atwood model GC6AA-9E water heater with a 10 gal unit. Does anyone know if there is one that can be used in the same cutout as my 6 gal? I have roughly 16 inches wide by 12.5 tall. Showers......my wife likes how the water is nice and hot, but it dosent last long, 4-5 min if that. I usually run the elec and gas when she goes in too. Do you guys have no problem with a 6 gal keeping up? Reason I ask is maybe mine isn't working to full potential. Before anyone gives the whole "navy showers thing", it's not an option, at least for her.
Any ideas from someone who maybe fit a 12 or 10 gal in?
Thanks
Leon

We have never had a problem with 6 gallons being sufficient. It takes only half an hour to heat up. I guess if you stand in the shower for ten minutes and run the water while you're doing the dishes you might run short. I only turn mine on twice a day, morning and evening.

Bear in mind, too, the added weight of a larger water heater plus the 33+ lbs. of extra weight for additional water. Maybe it wouldn't matter to your rig but it might to mine, since it's in the rear.

Perhaps change the shower head to a water saving one. Either that, or get her to not have the hot water flowing so fast. Either way will help the available hot water last longer.

The 10 gallon Atwood water heater is 3 inches taller and 3 inches deeper than the 6 gallon heater. You would need to reframe the opening, assuming you have enough clearance otherwise.

That figures.... I don't have room to go taller, but I do have extra depth. The height is hindered by the fact it is in a compartment under a bunk bed. Thank you for that info.

I like plug and play and the rebuilding/replumbing would be a show stopper for me being lazy.

If you don't mind waiting, Atwood should be shipping an on-demand tankless water heater that fits in a six gallon bay. I'd consider going that route once they start shipping.

Change out to one of these. Saves water and increases efficiency of the shower. We love ours.

Using a pressure regulator will greatly reduce the amount of water used, thus the less amount of water heated.
We only turn the water heater on when needed. Often times I don't wait for the water heater to turn off before getting in the shower, and the water gets hotter as I'm using it.
