Atwood 10 gal water heater vs XT. Is it worth getting??

We need to replace the entire 10 gal water heater. I thought I could just order a replacement. Found out the GCH10A-3E is not available. There is a Manufacturer's Number: 94023 GCH10A-4E that is available but the wiring is just a little different. That's not really a problem. A little different we can deal with.15-1/2"H x 16"W x 21"D.

As long as we have to deal with "a little different" there is another option... to go with the XT which says it has a way of delivering six gallons more of warm/hot water. Manufacturer's Number: 94026 15-1/2"H x 16"W x 21-3/4"D

It's about $100 difference between the two. I don't think the 3/4" difference in depth is a problem (I have a 2000 G Winnebago Adventurer.) But before I get into the decision making any further than this...

Can anyone tell me if the XT is worth looking into? Any problems being reported with Atwood's XT version?

  • Thank you BOTH so much! The last thing we need is another PITA on board. Thanks for the info and the links. Much appreciated.
  • Atwood XT model....10 gallon tank-----16 gallon 'equivalent'
    Water is controlled via t-stat to 160*F. It is then controlled to an output temp of 130*F via a mixing valve.
    Mixing valve CAN get clogged with calcium/crud with 'stuff' coming from water heater/plugging up hot side of mixing valve---- typically results in luke warm or even cold water output.
    Then you have to remove mixing valve and try cleaning or end up replacing it

    Replacing your older version 10 gal will require wiring changes.
    Older version 120V AC was direct fed to element/12V DC was just for propane
    Newer version 12V DC controls both functions/common control board/common set of tstats
    This applies to Standard and XT Models so you WILL need wiring changes


    Wiring changes 3E/4E (and 9E/10E for 6 gal) PGs 22-25

    Standard VS XT Model
    XT mixing valve issues.....PITA to remove/clean/$$$ to replace
    Standard 10 gallon.......2 adults FTd always had hot water. Cold in/hot out (140*F T-stat). Use electric & propane same time for FAST recovery if necessary.

    We have the XT in our rig. Still going strong. The water is heated MUCH higher than a standard water heater and a mixing valve on the backside mixes cold water with the hot water. Supposed to give you hot water longer than a standard. Only other difference other than price is that mixing valve. It will occasionally stick with minerals and such giving you very hot water.
    If your the type that likes to take long hot showers go for the XT, otherwise the standard hot water heater will do just fine.
    Hope this helps.
