I can't speak for the aqua hot sytems but Onan recommends not using these exhaust extentions.

Look under "parts service & support", "download RV Generator Handbook" Page 3 read the complete right hand column.
As for the Aqua Hot systems, I want to thank everyone who posted here for this info. Questions were answered I had also but never asked.

Aqua-Hot has approved the Camco Gen-Turi for use with the Aqua-Hot systems. There is a factory service bulletin that addresses this. If anyone wants a copy, send me a personal email and I will send it to you.

If you have not yet replaced the plastic drain valve, that is probably what is leaking. Much more information on my Forum, link is below.

Aqua Hot

I would love to have an Aqua Hot system in my coach. I have a 2007 Fleetwood Providence 39V. I contacted Aqua Hot directly as they are just a few miles south of me in northern Colorado. They sent me to a mobile RV tech who was one of their technicians until he left to start his own business. His estimate for the installation including the unit itself was a little less than $20,000. I was prepared for $10,000 but $20,000 is just too much. I won't buy another RV without the AquaHot!

We love our Aqua Hot in our 96 Vantare. Great hot water, great heat and always hot water when we arrive at our destination since the engine coolant runs through it as well. I also love the fact that I can use it to warm my engine before starting on bad cold mornings.

As far as I know, mine heats just fine even when the shower is on full demand.

Mine was in terrible shape when I purchased the coach because the yearly maintenance had been neglected. That was a pretty quick fix. The electric heating element went out on mine but I haven't replaced it yet. We didn't use that much any way. I will probably do that soon. Does anybody know much about changing that?

You probably have a model 431 or equal in your coach, which is the full size Aqua-Hot. It does not shut off the interior heat when making hot water.

The heating element rarely fails. Most of the time it is one of the thermostats. If your unit has serial number prior to 98001. then there is thermostat upgrade kit that adds a second (high limit) thermostat and replaces all of the 110 volt wiring.

Much more information on my Forum.

Thanks, Mr. Berke,

I will check the numbers. The electric side failed while we were gone one day. I would sometimes leave it on while the rest of our electric usage was low. I had the breaker turned on (As far as I know this is the only way I have to turn the electric element on) and when we came home we had no hot water. I looked in the panel and the breaker was tripped. I turned it off and then back on and it immediately tripped again. I assumed the element was bad but haven't pursued it.

Thanks again for the information. I went to your site last night after seeing your posts. It is nice to know you are out there with the knowledge we need on these things we love. Lol

My guess is that the A/C wire has failed. I am not exactly sure what type of wire was used, however the insulation around the wire fails. The 'hot' A/C wire touches the metal case and circuit breaker trips. That is what the wiring 'kit' addresses.

Every coach is setup differently, however it is not uncommon to only be able to turn off the electric element by turning off the circuit breaker. Most of the Bluebird coaches are done this way.

That is great information. You have inspired me to crawl in and investigate.

Thank you,

Evidently some work differently. Read #35

Hey Jim E

We also love our Aqua Hot. Domestic hot water has first priority. when shower and other hot water taps are shut off, heaters restart again fairly quickly. I assume all Aqua Hot systems work this way but I was wrong once before (grin).

They are similar, but work differently.

For model information, here: http://RVHYD.com/RVHYDModelInfo.htm

This listing is a work in progress, but gives you some idea of the different models.

Aqua Hot cold water

We were having problems with hot water in the shower, it would cool off quickly, some one suggested the valve in the shower needed to be replaced. I added that we had problems with hot water at the kitchen sink. Some advised it was probably the proporting valve at the aqua hot. Went out to check and discover my coolant reservoir was down to the intake valve. Put two gallons of propylene Boiler antifreeze in it and it seems to be working now. One cannot use just any antifreeze, it has to be the propylene boiler mix and it is like $24.00 a gallon.
