Eighteen months ago I purchased a new Holiday Rambler 40D with an AquaGo Instant Water heater (DKE60C-27267015). It doesn?t get too cold here in South Mississippi, but early this years the temp dropped to 17 and if froze. I had heaters running in the RV but it was not enough. I learned an expensive lesson? about $2,100 to replace it. When I got it back there was no power to the controller. I called the dealer and they told me the REV Group had suggested they disable the controller because of ongoing problems with the unit.
This winter, I learned disabling the controller prevented me from running the ECO mode which is supposed to keep the water heater from freezing. Since the RV is parked in my driveway and not moving, my only solution was to dump all of the water out of the Aqua Go, and for good measure dumped the freshwater tank and opened all the valves, running the electric pump until all the water was expelled from the lines (I hope). Then I removed the filter from the Truma and from the RV and took them inside.
I called Truma for a solution. The tech I talked to was appalled to hear that the dealer had disabled the controller, but I found out later that the REV Group told him to do that, because apparently the Aqua Go has been causing too many problems for them to handle. 
So as it stands I own a $345,000 RV I can?t take anywhere until next spring, because of course you can?t live in the motorhome without water. I suppose I should winterize the RV, but we have never needed to do that tis deep into the south. Our temperature rarely drops below freezing and I need the RV for work. Personally, I would have never spent that kind of money purely for recreational use.
Since the water heater only heats when you turn on a faucet. I?m afraid that even driving somewhere in temperatures below 32 degrees (mainly because of the wind chill), I would expect the unit to freeze just driving down the road.
There is one more issue that makes me wonder. I heard that the propane does not work with the RV is moving, so how would you get around that?
My question is, ?has anyone else out there had these problems with the Aqua Go?, and ?have you solved the problem??
 
For temp hot water (Dishes only) I have long used a 35 cup Coffee pot. makes very hot water. Just enough to do the dishes.

If the instant hot is the "Standard" size (Please don't ask me but others may know) you can replace it for less than 500 with a standard six gallon tank type.  DIY job in most cases.

If it is a DIFFERENT size.. well then you need professional help and a bit more cash.
 
That's

That's good information. I'll check it out. I would go back to a Suburban if I had the option, but I know the hole is too small for that. I thought  they were all too large. Maybe not.
 
Hi Bill, good to see you back on the Forum!  I'm another veteran from the CompuServe days and I think we crossed paths at the Tiki Lagun rally.

It looks like a 6 gallon Suburban water heater will fit the wall cutout with 1/16" to spare.

The Aqua Glow uses a 12.8 inch square hole through the wall and is 17.7 inches deep (19" depth clearance recommended).

The 6 gallon Suburban water heater uses a 12 11/16" square hole and is 19 3/8 inches deep.

Atwood water heaters require a larger hole, 16" W x 12.5" H for 6 gallons, 16" W x 15.5" H for 10 gallons.
 
Thanks, Lou. Oh, yes I definitely remember you. I've lost track of everybody. When Harlan Smith died, for some reason that pretty much marked the end of my involvement in the forum. Man we had some good times at those many little gatherings we managed to arrange.

I had the RVForum.com domain name for awhile and ended up giving it to someone that had the time to deal with it.

Wow, that was another life, brother. When was it... sometime in the mid-1990's I think. I had a Newmar travel trailer for the first half of the decade and a 1995 40' Holiday Rambler Imperial for the second half. Never had a lick of trouble with either, but this new beast cost me twice as much and has three times the problems.

I chalk it all up to technology. They put all this amazing technology on these things now and nothing works... LOL! Back in the 90's for example, we used to carry our satellite antennas inside our coaches and take them out and point them toward the satellite when we wanted to watch TV, now a technician has to crawl up on the coach, flip a bunch of switches and you have to have a 2-day discussion on the support line about why the HDMI cables aren't connected right,  and the Bu-Ray isn't working. Cruise controls top out at 75mph, so if your foot gets tired, you end up driving the speed limit om I-20 in Texas with 18-wheelers blowing you off the road.

Once I had to cancel a weekend trip because I could not get the steps to come in. The screen door is the wrong size and it sounds like a machine gun when you're driving down the road and only one TV works off the satellite, and the killer is that diesel is now nearly a dollar higher than gas. At 7.9 miles per gallon, you have to take out a mortgage on your permanent  residence to drive to Walmart and back.

This Aqua Go has been "H-E-Double L" from the word GO. Some rich guy in Germany is probably the only person on the planet who knows how the dang thing really works and they must have bought him out years ago. Mine came with a bad computer board (as many of them do) and I had to wait for 60 days until a new one arrived and install it myself. That pretty much fixed the problem until the temperature dropped below freezing. Down here in the deep south, we don't winterize our RVs because we use them year-round. I bought my first RV in 1973 and I have never needed to winterize one yet... well until this year. But, it looks like this high-dollar Aqua Go has 'winterizing' hiding in it's DNA. That little plastic bowl they refer to as "the tank" cost me $2,100 to replace. Actually, you can't get them fixed, you have to replace the entire water heater and send the old one back, but the installation has to be done by a licensed propane mechanic and the installation cost as much as the unit.

I would advise all of my friends, "If you live anywhere north of Cuba, you don't want one of these Aqua Go instant water heaters. Much easier to split up the times when you and the wife take your showers. And, if you have one you are happy with, you simply ain't had it long enough." They should change the name from 'Aqua Go" to "Aqua Don't Go."
 
Thank you for sharing this, reason enough for us not to go this route.  Sorry such a headache for you though and hope you get it worked out. 
 
You're very welcome. The idea of the Aqua Go is compelling. We really enjoyed the endless hot water. It's a great product when used as marketed. It's not too complicated, but most RV salespeople are not trained on showing the customer how to use it, and none (according to what I have seen) warn you about winter use. To make matters worse, the area provided by the RV manufacturers is not large enough for a large capacity water heater to fit in. So, I really think they have their backs up against the wall on this one. These things have no, (ZERO) insulation. I should have noticed that immediately when I looked at it. It is a block of ice waiting for an unsuspecting customer. There doesn't seem to be a reasonable resolution to this. I would like to add that the Truma folks have gone over the top trying to help, but if there is no fix possible, there is simply no fix. What were they thinking? Hope I am proven wrong, because we can't live with the current situation, and we are in the deep south. What about those folks in Minnesota or Kansas going to do? Sure they can winterize, but how long will they have to keep it winterized before they can drive the RV?

Wind chill is a ?RATE of COOLING? of an object that is exposed to movement of air. I.E. A wind chill of 10 degrees means that the rate of heat being removed is at the same rate as an object in still air at 10 degrees even thou the actual temperature temperature is 28 degrees. The temperature of the object will not be below 28 degrees.

Think of blowing your breath to cool a cup of coffee, no matter how hard you blow the coffee will never be below 98.6 degrees or the surrounding ambient air temp. (Forgetting the slight cooling caused by the evaporation of the water) It?s only increasing the RATE that your coffee is cooling.
 
Thanks, coxid. Yes you are correct; however I wasn't suggesting the wind lowers the ambient temperature. I was referring to the amount of time required to freeze the unit. For example, if human skin is exposed to a 15mph wind with an ambient temperature of 0F, human skin will freeze in 30 minutes. In the same temperature at 60 mph, human skin will freeze in just 5 minutes. I think the same theory can be applied to any object. Isn't that why we wrap our pipes? The Aqua GO has zero insulation. so any heat generated by the unit will leave the unit faster if the velocity of the wind is increased.

I have thought about putting a light bulb in there to keep the area warm. It couldn't hurt. I also have a controller that will shut the power off to the light if the temperature exceeds 45F and on when it drops below 40; however I am a little bit concerned about an errant spark around those propane fittings. If the hole was large enough and I could find an oil radiator small enough that was another thought, but again I am still a little concerned about fire and whether or not my insurance company would cover any damaged caused by one, not to mention what would happen if we were in the coach at the time.
