Aquahot tubing broken


Recommended Posts

Post a picture of where the break is.

Is it the cold Input or the Hot Output?  Pex should be fine for either.

Are you sure the break is external of the Aquahot?

How did it break?  Something hit it?  Freeze damage?

Worse case, it can be soldered with copper fittings (I like that better than PEX).

I have an Aquahot 431/12 with broken copper outside my heater. Can it be replaced with pex tubing?

If you are talking about the domestic hot water copper heating loop that, on the older aquahot, is wrapped around the outside of the boiler, no you need to replace it with copper.  Copper will allow heat transfer between the boiler and the water.  Pex would act as an insulator and not work.

How much heat loss do you think I will realize knowing that it is not as efficient?

I have it out and going to rebuild it. New to this type of fix and always looking for a simple solution to my problem. It would be easier to wrap it in pex and not as expensive. I just bought this Monaco and it has a lot of issues. Taking them one at a time.

If you going to do that, it will certainly melt the pex at the exhaust port, I would not and not just for that reason. I would at least just replace the bad section if the rest is salvageable, with a soft copper line,  like the one used for HVAC

I never gave the exhaust port a thought. Most of the copper was frozen and broke at some time. It sat for 2 years in a storage lot. I haven’t found a rebuilt one for a affordable price so I’ll try to rebuild this one. Is there a supply house that you would recommend for parts? Thanks

For the line I would look up AC supply outfit. All other parts I ever needed were available on the net. I just google the part. There are specialized places that are very proud of them so take your pick.

The old guru of Aqua- Hot is Roger Berke, there are others but I have dealt with Roger.  Take a look at his site, you can learn a lot there and buy parts if you want.

Anything with the term RV is automatically over priced but some things are used outside of RVs too.  I bought a tempering valve at a plumbing supply and used the guts  to rebuild mine.  I didn't need to do any soldering that way.

No doubt Roger started his services and used the internet to expand and is a top notch resource.  I was able to talk to him a few times to get info for a member on the old website.  He only, I think, takes questions and consults via email.

The second “Top Gun” is John Carillo in ABQ.  John worked on mine in 2013 at the balloon rally.  I have been able to call and actually talk.  Read his background.  He was a tech support for AH, as assembler and a “developer” or experimental tech for new products and has years of hands on experience.  I have met folks at CG that bought new systems or rebuilt systems and had to make extensive mods to make them work, mechanically and electronically.  They say he worked with them every step and was a gem.

So, now, another resource.

Carl, here is an old thread on another forum.  This guy is doing just what you are going to do, so you may be able to pick up some ideas.                                                      I remember another thread or two but this is all I could find.

OMG, my eyes were bleeding by then of his writeup. I feel like I can fix a whole lot of things but that is one daunting task.

Any idea if this chap runs a shop that one could travel to or is he strictly "sell you the parts and offer advice".

Roger is like so many of us,  he is not so young anymore.   I believe he was a mobil aqua hot tech but he gradually shifted to advising & selling.   As far as I know he still   rebuilds burners, send it in and he will rebuild it, that's what I did.  Don't take my word ,  contact him.

I am back. Carl Michael here. I ordered anew hot water tank from John corrillo to replace the old aquahot. Thanks for the information. I now am into other issues. When I run the Generator with the coach engine it runs with a load no problem. But when I shut down the coach engine the generator shuts down and gives me a overheating code. Any ideas.
