Hmm, that sounds like the ideal solution, what model theromstat were you looking at?

I never got that far when Jayco replaced the tankless unit with a standard one. I don't think it would be that hard.

The analogy I use explain this behavior is simple. You have a lit candle on the table and pass your finger through the flame. If your finger is moving rapidly, it is not burned as it receives little heat. The slower you move your finger, the hotter it gets. Move it too slowly, well, you get the idea.

After spending 3 months with the tankless water heater, and re-reading several times the manual, we got it figured out, shower wise that is. Turn on the shower's hot water valve only about 3/4 open. Adjust the thermostat so the water is just right. While showering, if the water gets a little hot open the hot water valve a little most. To cool just the opposite. We shut off the water while soaping up, and just point the shower head at the wall when turning back and adjust the water temp again. Actually this way worked just fine, when the heater works, but that's another story.

We're with MadDad --follow the same procedure and no issues. I've taken to charting cold water temp to see how the wall setting needs to be adjusted. I'm just using my digital thermometer when we set up to get a base line temp on the cold water.

On Demand Water Heater Reset Button Video

I posted in main forum, but thought I would add it to this thread.

Ok, so we went on our long awaited first outing in Apollo, our new Greyhawk 31FS. We considered a motorhome purchase for almost 2 years, I researched as much as I could, purchased all the accessories needed etc. We get to our first night of camping and NO HOT WATER!! I had tested the heater while parked in the driveway and it worked so I did not think a thing about it. Got to the park and NOTHING! I made a video about it on my YouTube Channel for anyone interested, the link is below.

In a nutshell, the water heater has a built in shut off valve for safety to avoid burning people when the water gets too hot. I turned the know to medium hot (figured I was being reasonable) and cranked it up. I waited, and waited, and checked it out, and read the manual, and turned it off and on, and...well you get the point. Around 30 gallons into my grey tank later I was no-where! I searched this wonderful forum and sure enough I found the location of the reset button. But, even with a PICTURE I still had trouble finding it! As part of my YouTube channel documenting my families adventures, as well as my personal backpacking adventures, I made a video introducing my subscribers to our new RV. If you are looking at a Greyhawk 31FS, check out the video because it is much more detailed than other videos on YouTube about this particular model. Anyway, I decided to make a video just on the hot water heater to help anyone in a similar, frigid, situation! Enjoy!

My Girard water heater is model no GSWH-1M, suppose to be the latest model, and does not have the "hidden" reset button. I have went thru a lot of testing with the Girard tech. We never did get it to work. I must have shorted something as we lost the 12v that was found everywhere he had me test. He told me he would have to contact Jayco to find out what fuse was hooked up to the heater as their was no label for the water heater. Still waiting for that call, been over a month. I did find the blown fuse that night when the lights over the table wouldn't work. The fuse was blown but the only label was table lights. Way to go Jayco!!! I replaced the fuse and have 12 volt to the unit, but it doesn't make a loud click like it did.
The manual says that to reset it wait 5 minutes, or shut off at the power switch for 5 seconds. Neither worked. It's going to the dealer in a couple of days. They know I am not a "Happy Camper". So to speak.

Mine is a 2015 Greyhawk FS, and is supposed to have the "latest model" heater. Watch my video above and give the reset button idea a try. If fixed my cold water issue instantly. Hope it works and saves you a trip!
