It's been one year since we replaced the water heater in my 2006 Jayco Feather and there are no complaints. The new water heater is working great and etrailer was a huge help when I purchased it. If you're replacing a water heater, I would read the Question and Answer section on here for the model you are going to buy. And also pay close attention and figure out if your current water heater door will work with the new water heater. They may vent in different places.



by:

This project proved more difficult than expected. The front was recessed less than the original 2005 water heater, so the gas line was 2 inches short. The water lines were positioned different. The old had 8 wires versus 4 on the new. The door was the same size, but the attach points and latch points were different. New door ordered. This 70 year old guy spent 12 hours on labor and several runs for parts. Very happy with the end result.



by:

ordering was easy. Shipping was good. It is working great. Was easy to install. Instructions were good. I would have preferred a 10 gallon option.



by:

I gave a 3 since both items were to be rated together. The water heater would have received a 4 and the door kit a 2. Reason is the door corner was bent and paint cracked on a corner. Chose not to send back and wait since the water heater was installed, needed to get the front covered. Package did not look dented, but guess it could have been dropped by the shipper.

Product works great



by:

Great water heater. Does need retrofit door for my application? Has been working great for over a year



by:

Initially I was worried about whether all my existing wires would correctly line up with the wires on the new unit since my old unit was discontinued. It was perfect. The water intake and outflow on the new unit was aligned differently so I had to get a couple of fittings and crimping tool... Was in the end a jiff to install and worked perfectly. Just remember to always winterize from now on lol. I highly recommend the products I purchased.



by:

Great water heater, 100% happy



by:

This was a great experience. James was very professional and my purchase was completed quickly. My new water heater was shipped promptly and was received a day sooner than promised. That was a good surprised. My order was received in excellant condition. I will install new unit tomorrow and report back on it's performance.
Thank you James.



by:

Both electric and gas function perfectly. I did need to order the switch but easy install.



by:

Easy install, great product, still working great.

The help I received from the first phone call to receiving the product in mere days was AWESOME!! I have not installed the new hot water heater but will give you all more feedback. Thank you all for your assistance!

I am sorry that you had to change out the control board. I do see that this water heater does have a 2 year warranty. For future reference I highly recommend contacting us to see if you could have gotten the replacement covered under warranty.


by:

We have Hot Water ! We live in our RV full time so we needed a Hot Water Heater of good quality. Time will tell if this Dometic Hot Water Heater is as good as the old Atwood which it replaced. The packaging was good ! Hot Water Heater appears to be well made. No problems installing the directions were clear and it fired right up. This replacement Hot Water Heater is smaller than our original so we purchased the enlarged door kit which fit perfectly. Great communication with etrailer which helped us find the correct Water Heater for our application. There website information was accurate and we had no problem contacting a human voice when needed.. We are Happy Campers !

One Year Later ~ Hot water Heater is working very well. Pros~ This replacement water heater seems to recover faster than the original. My previous hot water heater was only propane gas so this one has the electric option which works well. Cons~ Burner flame blows out when we have a 20 plus MPH. east wind directly. There are no flame adjustments just a circuit board which controls all the settings.. This hot water heater needs a external wind screen protector to mount over the door to keep the burner flame from blowing out..



by:

Replaced previous Suburban water heater which was no longer turning on and showing lots of rust. Close to drop in replace but note that the Suburban has rounded corners on the frame and this unit has square corners. Had to use a nibbler to square out the opening on my RV siding. Fortunately the wood framing was a perfect fit as well as the gas connection. The water connections are different. Suburban had a top/bottom hot/cold connections and this is left/right, so had to redo the PEX connections. Be sure to buy the control switch panel and note that the control wires are not that long and had to extend them. Only stars as I'm experiencing the P/T valve dripping after heating up. The manual says this is normal but it is dripping on top of the other components.

Wait time was short.personal on the phone were knowledgeable of products and upgrades.customer service and patience were outstanding.will use e trailer for all of my purchases.



by:

Happy with the Dometic water heater i got from etrailer. One year and it is still working great and this trailer is a full time live aboard.My old one was leaking.



by:

This replaced a propane only water heater and it is great have the electric option, saved me a ton of propane. It also went right in with no problems.



by:

A year ago I discovered that I needed a new hot water heater and it was just a few days before a major camping trip. My order was processed quickly and the item came in time for me to install it. I was extremely happy with the turn around service and the product.



by:

My water heater leaked and It was the old style that is no longer available. This one needed some conversion but it fit. I even made a pan to go under it in case it leaked again.
I used two 1/2” supply lines to make the connections because they were in different locations. Worked like a champ!
Had to use the door conversion which fit perfect.



by:

Perfect swap for our used RV's old water heater from the 90's.



by:

Package arrived very quickly in perfect condition, less than one week, sooner than expected.
I am building a cargo trailer conversion and won't install it for a while. I wanted to have for placement location planning. I am confident it will perform as expected.
AND ! the customer service is excellent ! I was even emailed directly by my sales rep with shipping updates.



by:

Will was super helpful in identifying the water heater I needed. The order process was simple and I received the new unit in under a week.
Great work!!



by:

The heater install was fairly straightforward.
There
was a bit of redoing to get it all alighned properly.
Main issue I had was the old unit had a 3 wire control system and the new direct replacement model had 4.So it took a bit to figure out the configuration as the install instructions were for the new unit.
To me a direct replacement is pull old out slip new in, plug and play.



by:

Damaged product. Received Damaged.

Wish I bought a different brand. Not efficient, takes a while for fire to ignite, heavy propane smell once activated.



by:

This product arrived on time was a direct fit replacement and works great!!



by:

Fairly easy install with a few modifications to the original opening for it. It fired right up after the install. Works great. I enjoy the 12 volt and the 110 feature.

    Atwood has a 6 gallon water heater you could use to replace the one you have now with the part # DMC74FR and you'd be set. It's slightly different but it's same capacity and would work great.

    The Atwood AT96110 Water Heater that you mention has actually been discontinued, unfortunately. Instead, the closest alternative we carry is the: -Dometic RV Water Heater # DMC74FR. This water heater has the same 6 gallon capacity as AT96110, measures similarly at 12-3/4" tall x 12-3/4" wide x 19-7/8" deep, and can run off of gas and electric.

GC6AA-9E: 12-1/2" T x 16" W x 18" D. If you have the space to accommodate the larger size then this water heater is going to give you a similar performance to what you already have.

  • Recommended Replacement for Atwood G6A-7 Water Heater
    The only tank equipped RV water heat option we currently offer is the Dometic RV Water Heater part # DMC74FR which is a 120 volt unit with 6 gallon tank and gas/electric operation. In regards to installation, this must be performed by a qualified installer, service agency, or gas supplier. That said, I have attached the wiring diagram for the above water heater below for reference. We no longer carry the Atwood RV Water Heater part AT96121 unfortunately.

  • Does Aluminum Tank RV Water Heater Use Anode Rod?
    No, there is no need for an anode rod in water heaters such as your Atwood and the Dometic RV Water Heater, # DMC74FR. The manufacturer uses a clad aluminum lining that protects against corrosion eliminating the need for an anode rod.

  • Can you Convert your RV Propane Water Heater to Electric
    I have a solution for you, but we do not offer a fully electric option hot water heater for RVs. If you have an Atwood, Suburban, American, or Moreflow hot water heater, you can use the Hott Rod RV Water Heater Conversion Kit # DGR6VP (6 gallon heater) or # DGR10VP (10 gallon heater). This kit will safely convert your propane water heater to electrical use while keeping your low pressure propane system in tact. The heater cord requires a 110v outlet, so if your RV electrical system does...

  • Recommended Replacement For An Atwood GC6AA-10E RV Water Heater
    Dometic bought Atwood some time ago and has slowly been phasing all of the Atwood models out so we do have a replacement for you but not the exact same model. The Dometic RV Water Heater # DMC74FR would be the closest replacement 6 gallon water heater to your GC6AA-10E. That being said, I highly recommend getting away from tanked systems altogether and getting the Furrion RV Tankless Water Heater # FR98SR. This unit features a heating capacity of 13,000 - 60,000 Btu, well above that of...

  • Replacing An Atwood AT94023 Water Heater
    The best option for replacing your Atwood AT94023 water heater will be the Dometic # DMC74FR. This will be very similar to your Atwood unit. The main difference is that this is a 6 gallon tank instead of your 10 gallon. The # DMC74FR itself is going to be slightly smaller than the Atwood. It uses a cutout 12-3/4" tall x 12-3/4" wide x 19-7/8" deep, so some modification may be required in order for the unit to fit correctly.

    All of the water heater models we currently offer require LP gas to heat the water so we don't currently have an electric heater to offer you at this time. There are electric models on the market but I can't really speak to their efficiency or reliability. Out of the options we currently offer I recommend going with the Furrion RV Tankless Water Heater # FR98SR to replace your GCH6A-10E. All of the options we currently offer, including the # FR98SR, are a bit smaller in size than older...

  • 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.

  • P-T Only Meaning On The Thermostat Of An Atwood GE19-EXT Water Heater
    The "P-T Only" you see on the ECO/T-Stat Label on your Dometic RV Water Heater # DMC74FR is a warning saying that only the pressure/temperature relief valve can go there so people don't try sticking anything else in its place preventing it from relieving excess pressure.

    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. Any replacement will not be an exact match but that can be overcome with some simple plumbing fittings and the Dometic # DMC84FR...

  • Recommended Replacement For An Atwood G6A-7 RV Water Heater
    At this point you'd be much better off replacing the unit entirely, but newer units are a bit smaller than the prior models so you'll likely need to do a bit of framing to fill in the gaps and properly mount the new unit. Tankless systems are much more efficient and can provide hotter water for much longer than their tanked counterparts. For a bit of perspective the G6A-7 has an 8,800btu rating and will give you roughly 12 galls of hot water per hour. A tankless unit like the Furrion #...

It was designed specifically to fit this water heater.
