Cool, hope you like it. We have yet to travel with our Gen. 3, but have tested it to the hilt in the driveway and love it. We leave on a 2 month trip to the Canadian Rockies in a few days. Looking forward to not fiddling with hot water so much.

I was not offered an upgrade by the Girard engineer however I did find him very helpful.

After fighting with that stupid heater for several years and attempting ever possible fix discussed on this forum .... the engineer hand held me thru a long drawn out testing process. It involved digital thermometers, measuring cups and stop watches.

At the end of the day, he provided me with the very simple fix that I outlined up above.

The fix coat me next to nothing and took less than 30 minutes to put in place.

This past weekend we were camping with that outside temp at slightly over 40 degrees f. For the first time since buying my 390BH in 2011 I had a shower that needed to be turned down because it was far too hot. Once the temp was set, the 4 of us had back to back showers. .. with no worries of running cold.

It took a hell of a long time but now that the system works ... I like it

I talked with girard tech just last week , talked to him about the bypass. He told me he would not recommend , it void the warranty. An after a time will burn up burner cause it's always on high. Just relating what I was told

[lefaivre]

Funny that they are changing their tune. The Girard engineer told me that the bypass changes the system from and auto/low setting to a high/low setting. You still have a switch on the main panel that allows you to drop the burner down to a low setting. Up here in the great white north the ground temp remains quite cold so the low setting does not often come into play. In a place lice Arizona or Southern California it could be a different story.

The recommendations were based on a number of tests and many measurements .... it is entirely possible that the conclusion would have been very different down south.

GOOD POINT

It is interesting, I am in Ga. Dealer is in Fl. But tech never asked me, this is not to say I will not try the bypass , like you said you would be controlling the flame on dial inside the coach. With gen 3. Is that not what there doing anyway? Thanks
Great conversation

I think the manufacturer is giving you two different suggestions because you have two different Generations of water heater.

Gen III flame is controlled by a temp. sensor on the output side of the heat exchanger. So far, works very well.

Ok. Maybe next step. Except I have to do a new door I understand
Thanks

That is true. I painted my own, some take it to an RV paint shop.

Check on the Legacy forum under "On-Demand Water Heater". On page two I posted a list of materials for the change out to Gen. III, and a few pictures. Hopefully your heater has good access to the rear so the plumbing won't be a pain. Mine was easy.

Yes, it a 2015 Charleston. In bathroom under washer/dryer there's a pop out panel an you can see the whole back ofHeater , I'll check out your post, thank you.

Read an seen your install nicely done, so my big question is now that you have it, like a home tankless can you control hot by introducing cold into flow with no problem
Thank you

Yes is the short answer. Flow rate and incoming water temp. does not effect it. You set the outgoing temp. you want on the LCD screen and it seems to hold it perfectly within a degree or so.

I have tested it to death in the driveway with all different flowrates and temperatures. Even moved into the motorhome for a week just to make absolutely sure we were happy with it and we are. No travel yet, leaving in a day or two for a couple months at least to the Canadian Rockies and down the west coast.

We endured all the issues you have described with your Gen. II and I finally threw in the towel and made the change.

Sounds great.
Have a good time
Thanks
Hopefully put an end to
( Honey There's No Hot Water)
Lol

OMG get rid of the Gen 1 Gerard. There is hot water on the other side. The new Gen 3 is awesome wish I would have done sooner!

[SEAYALL]

Thanks, going to make the call Tuesday.

If anyone needs parts or a G1 I have one I'd part with!

[captnrick3]

I have a complete G2 sitting in my garage. No issues with it other than it's a G2. One year old and was carefully removed.
