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


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.


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.


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..


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.


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.


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.


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.


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.


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


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!!


The heater install was fairly straightforward.
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.


Damaged product. Received Damaged.

That is terrible news! I will have our customer service team reach out to quickly so we can have this taken care of for you.



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


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


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.


Great product, still working good


We just installed it yesterday but it’s working great! Shipping was fast and tracking was easy- great customer support


The jury is still out. When I opened the box there was a screw in the bottom. I found the place it came out of and tried to put it in. But the hole was stripped. Several other screws were also stripped and almost all the rest were loose. I replaced the screws with bigger ones so they would stay in place.

Oh no! Sorry to hear this! Customer Service will reach out.


etrailer had the best price and shipped this thing fast. I also got the water heater door kit since my rv is older and had a larger cut out. The electric by itself gets very hot combined with the gas this unit will give you long showers. I gave 4 stars because the box was now sealed properly luckily nothing fell out


Packaging and everything was in great shape it was an exact match to my replacement less than an hour to install. Everything went perfect


Easy to install with the instructions and it works great


1 year and so far working perfectly


Did not come with a cover. But, the water gets hot so fast. I use electric and the propane at the same time.
