Hi all!
What are the thoughts on tankless hot water heaters? Do the Jims sell them?
what models are recommended for a GMC? I like to have hot water through the
entire shower, and they are portable in size, so I thought why not.

Has anyone here used them and what are the thoughts on them?

Sammy
GMCless for now. :)

bdub attached the link to my tankless water heater installation. This is by far one of the best upgrades we've made to our coach.

We have the 6L. Here is a 10L on ebay for $84. THAT is a great deal.

Sammy,
also in my opinion it was one of the best upgrades I've done.
I went with the Girard brand about 4 years ago. Unlimited hot water is definitely the way to go! But I think everyone is making them nowadays.
I also changed out the shower hand held faucet to a house model and took out all the water restrictures. The hand held faucet also has multiple settings so if I'm stopped at a overnight without hookups I can still shower in the morning on the low flow setting.

They are very easy to install in a Royale because of the cut out. But I don't know about the other GMC models.
Enjoy! Scott

I followed Ray's example almost to the T, although I removed the existing Propane RV refrigerator that did not work, and basically remodeled that cabinet so I could put in a couple shelves and a small "dorm room" refrigerator. I rarely if ever Boondock, so it made sense for me.

Here are some photos what I did.

So far it has worked great. Takes a little getting used to on flow, etc., but much better than having a tank.

I used a Girard products tankless heater.
A lot pricier but works a lot better imho, no worries about flow or anything it acts just like a normal water heater.

On the other hand, SHE's not likely to use ALL the tank water if the hot
water goes way before then. :-)

Ken H.

That is a lot like my thinking about wanting a noisy water pump. But having had a young life with only the potable water we had in the tank did leave an impression.

I posted this elsewhere. Re-posted it on this thread in case it was missed on the other thread.

Ray,

I used your setup as a guide when I decided to install a tankless water heater about 7 years ago. I had to modify your approach since you, as I recall, don't have a standard GMC layout.

I wanted to keep the original (actually had upgraded it to stainless steel a few years earlier) water heater with electric and the engine coolant loop. I wanted to be able to use the OEM when plugged in and the tankless when dry camping.

I plumbed it so that I could isolate the tankless heater from the plumbing when in potentially freezing weather (i.e. winterize it separate) on the way to or on the way back from warmer weather. We seldom dry camp in freezing weather.

The tankless water heater is installed behind my 3-way gas reefer.

I am very happy with having a tankless water heater.

I did a presentation at the Goshen 2011 GMCMI rally about my install and have included a link here to that presentation. It is a long presentation (70 slides) and I go into detail about what I did.

http://www.palmbeachgmc.com/PDF/tankless-heater.pdf

The only downside to my current setup is that the water temperature can fluctuate during "navy showers". Happens when the water is shut off to soap up, and then turned back on to rinse. At that time you can get hit with a shot of cold water which is annoying if you don't know its coming. I plan on adding a mixing valve to modulate the temperature if I ever get around to it.
