  • Atwood GCH6AA-10E Replacement
    It is possible that we have old answers that point to products we no longer carry but I do have a solution for you. Recently Dometic bought Atwood, and has been discontinuing most of the Atwood branded product, including the GCH6AA-10E. The only replacement for your Atwood is the Dometic # DMC74FR. Like your Atwood, it is 6 gallons, and runs on propane or electric, and has an automatic pilot. Because it is a little smaller in size you will need the Dometic # DMC84FR kit that includes...

  • Atwood GC6AA-10E Replacement Recommendation
    You can install a larger tank but that is all based on the space you have in your camper/RV and whether or not you're willing to possibly cut a bigger cutout hole in the wall of your camper/RV. An in stock alternative to the # DMC74FR would be the Furrion RV Tankless Water Heater - Gas - Automatic Pilot - 60,000 BTU Item # FR93FR. It has similar dimensions and can offer a a higher gallon output per hour at a similar cost.

  • Water Heater To Replace Atwood Gc6aa/10E
    The direct replacement for your Atwood Gc6aa/10E water heater has been discontinued. I recommend the Atwood RV Water Heater Item # DMC74FR which only requires a 12-3/4" x 12-3/4" cutout. This is a standard gas and electric, 10,000 BTU water heater which recovers up to 12 gallons of water per hour. Your current Atwood requires a 16" x 12-1/2" cutout. Since the new Atwood cutout is smaller, I recommend using the Water Heater Door Conversion Kit Item # DMC84FR. It is also available in black...

  • Replacement for Atwood G6A-8E 6 gallon Water Heater
    Yes, if you want a 6-gallon gas/electric water heater then the Atwood # DMC74FR is the only choice. You should know that it is more like 20" deep, and its width and height is smaller so you will need the # DMC84FR door conversion kit to help fit it to the old opening. Your installer will use a few common hardware store fittings when installing the new heater.

  • Correct Replacement for Atwood G6A8E Water Heater
    The correct replacement for an Atwood G6A8E Water Heater has been discontinued. That said, we do still have a replacement option. The Atwood RV Water Heater part # DMC74FR will work as a replacement but the cutout for the unit will be larger than needed and you'll have to run electric to the unit since this one is gas/electric and the one you have now is gas only. In regards to the larger cutout, this can be filled with the Water Heater Door Conversion Kit part # DMC24FR or part # DMC84FR.

  • Installation of Atwood RV Water Heater
    Installation instructions are included and from what I understand is not greatly difficult for a knowledgeable/trained person to install but for safety above all things, gas leaks and the harm that comes from such, is cause for the "Note: Installation and service must be performed by a qualified installer, service agency, or gas supplier". If this is not abided then warranty will most likely be voided. Since you will be using this as a replacement, not a new install, the current switches...

    We do not carry the tank only as a replacement part but I will have a solution. You can replace it with the Atwood # DMC74FR six gallon water heater, which will have the added benefit of automatic ignition. The discontinued water heater you have had an aluminum 6 gallon tank and manual ignition. Most any water heater will fit in the area of your old water heater.

  • Replace The GC10A-2E Water Heater
    My suggestion, providing your space allows, is the Furrion RV Tankless Water Heater, # FR93FR. This can be used to retro fit an Atwood GC10A-2E providing the envelope is large enough for fitment. While the physical, overall dimensions are 19-3/16" deep x 12-5/8" tall x 12-13/16" wide the installation instructions (Figure 2, page 5) has a note stating that to install on a carpeted area, a metal or wood panel is needed to extend at least 3 inches past the depth.

  • Replacement Atwood Water Heater
    The best replacement option we have for an Atwood G6A-7 Water Heater (Gas Only, 6 Gallon, Manual Pilot) is the Dometic/Atwood RV Water Heater part # DMC74FR (Gas or Electric, 6 Gallon, Auto Pilot). This is one of the few models that will run on electric also so you can save your propane when at a campgound with electric hook ups. This is also fits in a smaller openind so you will need the Dometic # DMC84FR door and fit kit.

  • Are the Brackets For the Water Heater Door Conversion Kit Included on Both the Black & White Option
    The door you're seeing for the Dometic RV Water Heater # DMC74FR is a conversion kit. The black is Water Heater Door Conversion Kit # DMC24FR and the white is Water Heater Door Conversion Kit # DMC84FR. I reached out to the manufacturer and they confirmed that both the black option and white option come with the brackets.

  • Recommended Replacement for Atwood GC6AA-9E RV Water Heater
    The Dometic RV Water Heater part # DMC74FR will work great as a replacement for an Atwood GC6AA-9E. They are both gas and electric with a six gallon tank. It will allow you to reuse the existing door already on the trailer. The swap should be pretty straight forward as they both fit the same size cutout and have similar connections.

    The Atwood RV Water Heater - Gas and Electric - Automatic Pilot - 120 Volt - 10,000 Btu - 6 Gal Tank # DMC74FR is out of stock with no confirmed date of restock so I recommend going with the Furrion RV Tankless Water Heater - Gas - Automatic Pilot - 60,000 BTU - 16" x 16" Door Item # FR98SR. It has 19-3/16" deep x 12-5/8" tall x 12-13/16" wide dimensions and comes with a 16" x 16" door but larger ones can be ordered if needed to cover your cutout. The # FR98SR will produce 19+ gallons...
