Smile Hot Water not hot enough??!!

We just bought a 2010 21 ft Flying Cloud. LOVE IT!! We camped this weekend and the hot water temperature was only slightly above what I would call tepid to bathtub warm for a baby. Can't figure out how to raise the temperature. I looked at the manual(s) and read all the instructions. Still can't figure it out. Help, please????
I am new to AS and not mechanicall gifted, so please use lay terms for us newbie types.
All guidance is appreciated and welcome!

On ours, there is an indicator ON the WH that can be adjusted from tepid to YIKES!

Have a look behind the hatch, yours should have one, too. It's fairly obvious...

Of course, another possibility is that the WH just isn't turned on. You should be able to feel heat from the pilot light, even if the furnace isn't heating. If you don't, get out the book and read some more, and/or let us know on here.

I know the WH is lit because the water is actually getting slightly above hand-comfort "warm". It's just not what I would call even close to "hot". I opened the exterior hatch and looked, and looked, for some kind of adjustment know, lever, wheel, etc. I found nothing that moved or looked like it would move. Am stumped. I guess I have to give up and call the dealer; would just prefer to learn how to solve this sort of thing on my own.

there is no thermostat 2 adjust.

IF the temp climbs over the hidden/built in temp setting,

the pressure/temp RELEASE/bypass valve will let OUT hot water down the side of the stream.

typically the mixer valve for the shower is the issue if ONLY the shower lacks hot water...

IF hot is lacking at the lav or galley sink,

the issue is typically the handles/valves that OPEN the water lines into/out of the water heater...

look in your owners manual under "water heater bypass valves"..

find them and turn them as shown in the PICTURES in the owners manual.
__________

occasionally the issue is debris in a water line that's impeding flow,

but usually it's the handles on the water lines not being FULLY open or closed.
__________

the gas heating takes 10-15 minutes TOPS to fully heat 6 gallons....

the electric element for the water heater takes longer to fully heat a tank.

but u cannot adjust the temperature INSIDE the water heater...
____________

dozens of threads here on this issue and with pictures of the tanks, valves and so on...

Well, it appears an apology is in order, as my memory has been playing tricks on me (again).

I will blame it on the fact that I have had two (2) new water heaters installed in the past 6 months IN MY HOME, and I can guarantee you that on THOSE water heaters, there IS a simple temperature control.

Not so, apparently on the brand new 10 gallon Atwood that I had installed last December in Henri. (see photo below)

AND YET, there is a sticker on said water heater, warning about the dangers of too-hot water, and counselling the operator to read the manual before adjusting the temperature.

Unfortunately, I can tell you that there was no manual in my new water heater. I opened the new, sealed box myself, and not one document at all was there inside.

A mystery indeed. Good luck solving it. 2Air is on the right track, I think.

I vote that the bypass is closed...

Mary,

If you look at the left photo above on Aage's post, there is a blue dial you turn clockwise to get hotter water. I have mine set at warm and it is very hot. This is if you have an Atwood hotwater heater. Mine is LP only so yours may be different. Mine is brand new but the white letters came smudge and hard to read.

Also let me add that in the hot days of summer the hose and lines inside heat up enough to make you think the LP is heating when it is just the sun. When you look in the panel you should see the pilot light burning and a loud blowtorch sound when it is heating the tank. If new the gas shutoff could be turned in the off position.

Good luck.

Nick you are wrong the blue dial only sets whether the water heater is on, pilot or off.
Old wtare heaters had a temp control dial but not on new ones.
2air is on the right track one of your winterizing valves may be open allowing cold water to enter the hot lines.

Chris you are correct. I did not look at the top of the controller for the pilot knob. Mine is LP only new last year and looks like this photo. The Atwood website has the manual here.

no harm, no foul aage...

there are still some new water heater models that DO have temp adjustments,

but none of the units a/s puts in new trailers do anymore.

clearly this is a safety/liabillity/cya thing.

aftermarket one can still get a themostat ON a water heater or ADD one as a kit...

but mary needs to fiddle with the knobs on the red and white pex lines,

or have the dealer fiddle with it.

cheers

A couple of simple suggestions:

1. Make sure your hot water tank is full before you apply heat by opening the bathroom sink fawcet to hot and let it run a bit. If you're getting air in the line, the tank may not be full.

2. Check under the sink--there is a mixer valve in there that will blend in cold water with hot--this lets you make the water temperature cooler and saves hot water too. If that valve is partially open, you're getting a mix of cold and hot.

Best of luck to you, and welcome to the best website on the web!

To all, First, thank you for so many responses! I really appreciate the willingness to try to help me figure this out. I am going to spend some time with the Caboose tomorrow, Friday, to see what is going on. I will plug in the electricity, hook up a "city" water hose, fill up the tank by opening a faucet to ensure no air in lines, and then flip the WH switch in the bathroom. Will wait a while and see what happens. I will read my manuals and see what I can find concerning the bypass valves. Will locate them and follow pictures to see if I can get a better mix of hot and cold. I will post my results. whew, am tired already. LOL.

An update to my hot water problem...

Well, yeah, Success! Nothing like reading the manual ten or twelve times to finally help me solve my problem of tepid "hot" water. The problem was the pex valve positions. there are four such values surrounding my actual WH. One of them was shut when it needed to be open, so I think the amount of hot water going to the various faucets was inadequate. Anyway, by chance, I turned the valve and, presto, now we have hot water. I have no idea why this worked.....airsteam dummie that I am.
thanks to all, MEH

Well done! It's not perspicuous, but you kept at it and figured it out. That's part of the fun of Airstreaming!

You can also release water from the overpressure relief valve and/or external hot water drain to determine if it is heating properly. If you are getting hot water at the heater then chances are it's an incorrect valve position.
