Warm water

The water heater in my Fleetwood Terry cycles on long enough to warm the water, but there is never enough for a shower. What's with that?
What do I need to check first? I'm a newbie with no owners manual.

First thing I would check is, if you have an outside shower, make sure the taps are turned off.

You may only have 6 gallons to work with. If you are taking a long, hot shower like you do at home, it's gonna be tough. Turn off the water while soaping up.

I run both the electric and propane at the same time, which makes a big difference. The recovery on propane is usually faster than electric, but on mine, I can also run both together.

Check the flame - is it blue or yellow & sooty? We had a spider in venturi tube on ours and it didn't do much until I cleaned it out.

Top cause of "only warm water" covered above (Outside shower).
Top cause of "not enough hot water" also covered above (6 gallon heater)

Top solution to Not enough: Oxygenetics Shower Head.. I installed one a couple days ago and am about to use it (have used in the past at one campground that had them) they are a bit different, In my RV the install involved ZERO tools.. Just hands.

As stated above I do the below:
1. Oxygenetics Shower Head
2. Electric element on and gas on at the same time
3. Turn water off while soaping up

If it is just me showering I can take a 10 minute shower with the hot water on most of the time without running out of hot water. In fact, I've never taken one long enough to run out so I can't say how long it will go. When my wife is going to shower after me I practice conservation so she is guaranteed a hot shower.

Many thanks for your input. I have learned from several sources that I most likely have thermostat problems. I found a 40-page Atwood manual online that really covers all the possibilities, then a company spokesperson promptly gave me more information and two parts numbers, for a gas and an electric thermostat. --Lark

I get the feeling from reading the original post it starts out hot but then gets warm/cold. This is a matter of too long in the shower.

First you can try the navy style shower, Only run water when needed, I have done that in the past when using the RV shower, MANY RV showers have a cut-off switch/valve in the head, mine did not , got one at a big-box home improvement store (They are the standard size) and installed... Got another when I got my Oxygenics head last week. Liking that new head.. Uses about 1/3 less water per the lit.

And that is the other thing you can do, Oxygenics, but I said that already.. NOTE: since I put my original quarter turn valve at the start of the hose (both heads are telephone type) I did not use the one that came with the Oygencis.. I now have 3 shower heads in this coach, ONe for use in selected government parks in the winter.

Have you checked your bypass valves if they are all in the open position you could be mixing cold water with the hot. I would think a bad thermostat would prevent it from producing any hot water it would all be the same temperature.

warm water

Agreeing with ELF111, we had our bypass valve on & it will mix cold with hot & all you will get is warm water in the faucets even though the heater has the water heated. Don't ask how long this went on before we found the cause. Pop open the overflow carefully & you will know if the water is hot & the bypass is the culprit.

We had to replace the mixer valve in our Atwood - major pain, requiring removing a wall by the clothes washer/dryer to get to it. Once repaired/bypassed, there is tons of hot water for showers. As noted, if the water is HOT in the tank as checked by gently releasing some water through the pop off/overflow valve on the heater, I'd suspect the mixer valve as the culprit.

That is a good idea. Run the hot water in the shower till you get to that point where it turns cooler. Then go outside and flip the pop-off valve. What is the water temperature there?

We have a DSI gas / electric water heater. The water is super hot....Taking a shower I might be only using a 50/50 mix between hot and cold. Yes, I do turn the showerhead slide button off between wetting down and soaping up, but have never run out of hot water. Just to play it safe, the next one in the shower will wait about 15 minutes before they take their's. They must insulate the hot water tank good, because even if I turn off that night, in the morning the water is still warm.
