Girard GSWH-2 3rd generation tankless water heater

Does anyone have the Girard GSWH-2 the 3rd generation Tankless on demand water heater working in their RV . It appears to be copied from the Suburban On demand water heater . Does it in fact work ?

I do, and replied in your last post as I had the same problem. Solenoid stuck closed. Tapped solenoid (as per dealer service tech). Unstuck. Works great. Good luck...Joe

Solenoids are just below and to the left of the fuse...

Do you use hot water only or do you mix cold like a regular water heater ?
The build date of our unit is 6/15 I wounder when Jayco switched to the 3 rd generation .
Girard Teck support with a few simple test was able to isolate the problem to the gas Solenoid and is sending me the part .

We run the water both ways. In the shower, my wife likes the water hotter than I do, so she'll just use the hot water. I'll add a little cold water to get the temp to my liking. We have the inside tankless thermostat and can adjust the temp that way too.

I have the Girard GSWH-2 the 3rd generation Tankless on demand water heater. It works flawlessly when using full hookups but not so much when boon-docking. Since I mostly boon-dock, I'm replacing it with a standard Atwood water heater. It's for sale if anyone is interested.

I still don't see the attraction for the tankless water heater. Why would I want to pay to heat water (my propane) when on a full hookup site? Even when boondocking I can choose propane or electric since I have a generator.

Just don't see the need.

If you have it set up right, you can use the shower as you do at home. I have a DW and two DDs. When its time to shower they go in one after the other and take as long as they need, not as long as the 6 gallon water heater will allow. And there is no waiting for the heater to recover either.

Finally when I decide to hop in, I can stay in there for 1/2 hour or more if I choose. The hot water keeps on coming.

Our coach has the tankless water heater. Works well for us, but I'm wondering...

The tankless heater uses propane, while the tank type can use propane or electricity.

In matters of hot water I wonder which is more efficient, propane or running the generator (at one half gallon per hour)...???

Our GSWH-1M version 3 build date 6/15 uses very little propane even though it is stuck on high and supplies all the hot water you can want . What I am trying to figure out is there are 3 different Girard models . We have the second model with the dial in the bathroom to control the temperature. The third model had a digital controller that can be use like a conventional water heater . ( looks like a copy of the Suburban trakless ) Is everyone that dislikes the tankless water heater have the same Model Girard Tankless . It appeared that the 3rd model works , Although I would like to know why people don't like it for boondocking ( waste water ? )

If I know there is going to be a need for a LOT of hot water I can run my water heater on both propane and electric at the same time. While not exactly unlimited hot water it is very close. But I have the option of either or both.
