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:

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:

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:

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'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



by:

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



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, 100% happy



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:

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:

Easy install, great product, still working great.

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.

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:

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:

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:

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!!

  • Atwood G6A-8E Water Heater Water Not Heating Up
    There could be a number of reasons your Atwood G6A-8E water heater is not heating the water properly. It could be because: -The By-pass kit valves not set properly. What you'll want to do is put the valves in the proper position. The main purpose of the water heater bypass valve is that it prevents anti-freeze from going into the heater tank when winterizing your RV water lines, so this could be causing the issue you're having. -The thermostat is not seated properly against the tank....

  • 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.

  • Recommended Replacement Water Heater For A 2005 Itasca Spirit
    Hi Brad, To replace your Atwood G6A-8E water heater you'll want the Furrion RV Tankless Water Heater # FR48SR. The industry has been moving towards tankless water heaters and have dropped the size of the water heaters down a bit to minimize the space they require. Tankless water heaters offer a much more efficient and and longer lasting heating option. To put it in perspective the Atwood unit you have is rated for 8,800 BTU's and produces about 7.2 gallons of hot water per hour whereas...

  • Troubleshooting No Hot Water On Tap With An Atwood RV Water Heater
