The only name I can find on this WH is Domestic. I read it on gas & electric when I first pulled into this park so I could get a shower in short order. Other than that one time, it has only been on electric. I just flushed it out so we'll see if that did the trick.

Dometic IS Atwood (Dometic owns Atwood)
Model Number will be listed on data sticker in outside compartment
IF 10gal model will be GC10A-4E
If 6gal model will be GC6AA-10E

If it is GAS/Electric Combo and you are in CG why do you have the Propane ON?
Propane Noisy then you can adjust the air shutter to control flame (fuel/air ratio)

Only 1/4 of slots should be open for a good BLUE Flame that is fairly quiet

YES you can turn BOTH ON for fastest recovery time
Both use the same set of T-stats so both will turn on at same time and off at same time.
At night...turn the GAS off so you don't have to listen to it fire up


Is it time for your medication or mine?

Our water heater " suburban I believe " has an electric on-off switch at the WH itself, another electric on-off switch at the control panel and separate Propane switch.
I've not seen this configuration before.

Regarding the OP's concern.
We've yet to use Propane to heat water when hooked up to electricity.....family of 5 until kids moved out.

Sorry to be a pest but what is involved in cleaning out the water heater? Open the PSV and flush?
I was referring to the cleaning and adjusting the propane to reduce the noise.

Suburban OEM electric ON/OFF Switch is in the outside compartment
Some RV MFGs install an additional on/off switch INSIDE RV for convenience of owners (OEM Switch is inconvenient but was installed in outside compartment as a safety measure when working on electric element. Propane can be disabled by disconnecting wires on gas valve solenoid)

OEM Switch and Added Switch Inside are wired in series so BOTH have to be ON for electric element to work.
Outside one can be left on and Inside Switch used for turning WH on/off

Chatting with my daughter yesterday (her family has camped close to 50 nights this year), she said the same thing and added how LOUD other campers water heaters are !

I flushed the WH tank out yesterday and it did reduce the noise considerably.

Our WH is a Dometic which, as I understand it, is Atwood as Dometic bought out Atwood. That is the only name I can find anywhere on the unit or the paperwork. This water heater does not have an annode to be replaced.

There are a few reasons why this WH needed cleaning as far as I can discern. 1) We have been Full-Time in this rig since the last week of May. 2) The park we've been in since the end of June has some very hard water. Many of the Long Timers here have installed water softeners for that reason. I was amazed at all of the calcium that washed out of my water heater.

I used Gas and Electric together only the one time so the water would heat faster, which it did. At all other times I have only had the WH on Electric heat. I would have expected to hear the thing more had I been heating my water with gas. The electric option has worked great as saved me a lot of money on propane.
