May have to push lemon law
Information from other forum users is that Jayco Service has authorized the replacement of tankless water heaters with a traditional 6-gallon tank-style unit. A 6-gallon HWH can fit without enlarging the outer opening according to posted information. I went bigger because I wanted more capacity.

But I don't know whether Jayco installed a heater which also has an electric element as I did with mine. So not only do I have more consistent temps, but I also can use campground power (when available) to heat water rather than burning propane thereby saving another resource (propane) at times. When several showers need to be taken in succession the gas switch will go on too.

I have read that 6 gal will fit and I know it won't have electric element in it which is fine has to be better than tankless crap\

I replaced mine and it has electric and propane. I didn't get it replaced by Jayco but on my own dime. Not sure what Jayco would install on their dime.

Next spring I plan to install either a hot water recirculation or a purge system system to provide almost instantaneous hot water to the fixtures. The purge system would incorporate a momentary switch operating a solenoid valve that would dump hot water back into the fresh water tank. To be used mostly when not hooked up to campground water. That way water isn't "wasted" waiting for it to get hot. Push the switch for 10 - 15 seconds and cold water will be purged from the line. I may get fancy and install an automatic (but adjustable) delay circuit to operate the valve.

Also with a traditional tank-style water heater when someone is showering and reduces the flow to a trickle, the temperature will remain constant unlike the Girard where the heater shuts off the burner at very low water flows to prevent scalding temperatures.

For those owners who spend most of the time with full hookups the Girard, (and probably especially the newer model with electronic controls) is probably a good fit. But for those of us who camp frequently without hookups wasting water waiting for it to get hot is a "big deal". We also shouldn't forget having a finite amount of grey water holding capacity when not at a sewer site. Dumping water into the grey tank waiting to get hot eats up two of our resources!
I really don't understand why a propane only water heater is a good fit when you are on a full hookup site where the electricity is prepaid. Maybe on a monthly site where electricity is metered and the rate is high, but I guess I just don't understand.

Please explain to me why a Girard is a good idea anywhere? I'm not trying to cause any issues here, I really just don't understand the need or the fit.

Thanks.

I have to agree. I think the powers that be, thinks it sounds cool and that's about the only reason.

In my opinion there are a few reasons it might be good, some benefit the manufacturer, some features maybe help some owners.

I believe the unit is less expensive up front than a larger (10-gallon and up) traditional tank-style DSI/Electric units to provide more hot water than a smaller tank-style HWH. It also is much lighter both in its construction and when full of water (it probably only holds less than a gallon). It does not require "bypassing" for winterization, it can be filled with RV antifreeze and left that way, whereas for tank-style units that is not recommended (antifreeze cost and corrosion issues?). When all the "variables" are managed, such as incoming water pressure, temperature, and flow, it can deliver unlimited hot water for those with large families and/or those that want to stand under the shower for long durations. But you need to be hooked up to camp water and sewer, otherwise you will exhaust your FW tank and fill up your grey tank quickly. You also are not expending propane to "store" hot water for the majority of a time when it isn't being used. So there may be some saving for some owners in that respect.

It is possible the newer Girard model, which incorporates electronic controls, will better manage the variables. But I talked directly to a Girard company technician and he admitted even the new model cannot compensate for very low flows, such as when a person (without hookups?) is throttling the flow to save water. It cannot lower the flame enough to provide consistent temperatures at very low flows. Many users have to remove flow restrictors in their shower/faucets so that enough flow occurs to prevent burner "cycling" and the resultant scald/freeze temperature swings. Certainly not conducive to water conservation.

I grew up in a house with 6 kids and two adults and a 40-gallon hot water tank. From an early age we had to ration hot water. I enlisted in the Navy at 17, and at that time on a ship ALL fresh water is a precious commodity. Hence the term "Navy" showers. Just like being at a campsite without water and sewer today I suppose. Even though I now live in a stick house with city water and sewer, my wife and I still shower that way every day! But with the Girard in my motorhome (originally) it just did not work. So I took it upon myself to install a 10-gallon Atwood XT water heater in my unit. Now I have the ability to throttle the water as desired, and I can heat it with campground electricity when available.

For those of us who camp on full hookups only, the Girard is a real boon. We 'camp' to vacation, and we all appreciate the ability to take a normal residential shower. Once you get the hang of getting it set up, the Girard performs fantastic. Granted, each campground is different (water pressure/water temp) so you have to fiddle with it each time you're at someplace new.

If I were boondocking or camping w/ only electric and no hookups, this Girard would be a disaster. However, that's not how we camp so its a non-issue for us.

Now if a manufacturer could come up with an affordable water heater that could operate in either an instantaneous or storage mode, use both propane and electric (when available), THAT would be be something I would jump at!

Jopopsy, I too use FHU campgrounds. Unfortuately the Girard did not work at high altitudes - 7,000 ft and above. My replacement HW heater (paid for by Jayco) manual contains info re degraded performance at alts above 4,500'. Since some of Jersey is now below sea level, you may not have this problem

Didn't know about the altitude deal - obviously doesn't apply to me. Hrm.
