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:

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.



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:

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



by:

Great water heater, 100% happy



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

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:

The water heater control board was bad when unit was installed bought one from dinosaur made in USA now it works fine, Biggest issue is that I have to turn it on and off manually easily forget to turn off



by:

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



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:

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.

I've purchased from etrailer a number of times and the product is always in good shape when it arrives and is received quickly. Thanks for great service

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:

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:

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:

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:

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.

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!!

  • Is There a Replacement Water Heater For the Atwood G6A-8E
    The Atwood you referenced is no longer available and there is no direct replacement currently available for your Atwood G6A-8E. I recommend the Dometic RV Water Heater - Gas and Electric - Automatic Pilot - 120 Volt - 10,000 Btu - 6 Gal Tank Item # DMC74FR. It is very similar to what you had. The Double-Panel On/Off Switch # AT91230 will allow you to power the electric and gas components on and off individually. It mounts in your coach for easy operation. When it comes to Installation...

  • Troubleshooting A Dometic RV Water Heater That's Overheating Water
    Hot water heater models like the Dometic RV Water Heater # DMC74FR use and ECO (energy cut-off) Thermostat instead of an adjustable thermostat. These thermostats are preset and are not able to be adjusted. They are typically set for 130 degrees so if you're experiencing temperatures higher than that you'll want to replace your thermostat. You'll have to reach out to Dometic for a replacement thermostat.

  • Troubleshooting A DSI-FLT Error On An Atwood RV Water Heater
    DSI stands for direct spark ignition and FLT stands for fault. Normally you would see this error code on your Dometic RV Water Heater # DMC74FR if it tried to ignite the burner on the water heater but failed. First thing is to check your propane supply. The second thing would be to check the burn chamber to see if it is clogged with carbon flakes and clean it out. Since you're not running it in gas mode it means that the ECO (Energy Cut Off Switch) is causing your issue. This switch will...

  • Replacing the Atwood GCH6A-10E
    The direct replacement for your Atwood GCH6A-10E water heater has been discontinued. I recommend the Atwood RV Water Heater, # DMC74FR as the best option from our site if you want a gas/electric with a 6 gallon tank. This is a standard gas and electric, 10,000 BTU water heater which recovers up to 12 gallons of water per hour. This equires a 12-3/4" x 12-3/4" cutout whereas your current Atwood requires a minimum cutout of 16" x 12-1/2". To use current door there will need to be some level...

    Many older Atwood water heaters have been discontinued, the most straight forward replacement for yours currently is the Dometic RV Water Heater - Gas and Electric - Automatic Pilot - 120 Volt - 10,000 Btu - Item # DMC74FR. This is a 6 gallon gas/electric like you currently have with an automatic pilot. This uses 120V power and comes with the switch panel to operate it. The Double-Panel On/Off Switch # AT91230 will allow you to power the electric and gas components on and off individually....

  • 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...

  • Best Replacement For Atwood GC6AA-8E Water Heater For RV
    To replace your Atwood GC6AA-8E, by far the best option is a tankless water heater, and the one with the most similar dimensions is from Furrion: - Furrion RV Tankless Water Heater # FR93FR The # FR93FR measures 12-5/8" wide x 12-5/8" tall x 19-1/4" deep, which is very close to the 12-1/2" tall x 16" wide x 18" deep the Atwood, so you'll just need to ensure you have the added room for the new heater. Going with a tankless water heater is something that you'll never regret doing, because...

  • Recommended Replacement Water Heater for Old Busted GH6-7E
    To replace your GH6-7E water heater I recommend the Dometic RV Water Heater # DMC74FR as it also runs on 120V power, and is gas and electric with an automatic pilot. This measures 12-3/4" tall x 12-3/4" wide x 19-7/8" deep which may be different than what you currently have, and you'll need to also get the Black # DMC58FR door for a complete look - but you'll need to fill out the rest of the gap with some trim.

  • Water Heater Replacement Recommendation for a Dometic GC6A-7E Model
    I recommend using the Dometic RV Water Heater # DMC74FR for your application as it's the best fit as far as dimensions and specs go. This uses both gas and electric for operation so you'll need to get your propane leak fixed (which you'd want to do anyways). Unfortunately I don't know of any pure electric water heaters for an RV so if you want to use a water heater you need to fix that leak. If you aren't sure where the leak is you should be able to use a soapy water test to figure it...

    For your 2004 Itasca Suncruiser, with an Atwood RV Water Heater w/ Heat Exchange AT94023, which is no longer available, I recommend going with the Dometic RV Water Heater # DMC74FR. This tank is a bit smaller at 6 gallons, versus AT94023 10 gallon capacity, but will also produce up to 12 gallons of hot water per hour, which should be plenty. Additionally, this unit has an aluminum clad tank, that does a great job preventing corrosion, and also has a high-temperature limit switch, which...
