Coastal Builder. Any updates on your Aqua Hot?

OK, I called Aqua Hot yesterday. I was trying to find out what diameter, length and type of copper tube I need to buy in order to redo my fresh water system. The tech I talked with said he couldn't give me specific information on the unit because they hadn't made this style in 18 years (possibly before he was born from the sound of his voice). He was pretty certain that it took 50' of 1/2" copper tube to do the job. It also didn't matter if I used type K or type L copper tube, it just needed to wrap tight on the boiler. How disappointing that this is the tech advise available. Evidently it isn't important to even try to look up the information for the general public who own an older unit, which doesn't bring in thousands of dollars for the company.

I'll do my own research on this forum and get much more accurate, friendly results.

End of rant.

Thanks to all the forum members for their help and listening. And an extra big thank you to Rudy for taking the time to answer some questions on the phone. Truly a gentleman and a scholar. I hope to make it down that way to meet Rudy in person someday, and when I do, lunch is on me ^.^d

The link John Morales put in the response above has the info I believe..

One other thing when you get to it..

When bleeding the system.. make sure you have the coach level to push the air out.. you will have issues if its not level..I can tell from experience..

That might be interesting. The driveway is too steep to get completely level. I can get close but no cigar .

I have not done anything yet on the AquaHot.  It fires up great. It has sat for maybe 3 months now.  I have fired it 3 or 4 times in that time and no problem.  No white smoke in the exhaust.  I do not have gallons of fluid under the coach. I got a new scope and can see inside.  Pretty cool actually being able to look inside. The fluid is low but is above all the inside parts.  It measures 7 inches from the TOP of the radiator cap tube to the coolant right now.  The neck of the fill tube is really rusty and nasty. But I can't get a good look up at it after I go past it.  I wonder if it's the neck issue I have read about.  Still grasping at straws not to get a new or rebuilt unit.  I could add 2 gallons a week for years for what it would cost to rebuild/replace.

Coastalbuilder. I would add fluid to the radiator fill neck. When it heats and expands it should go into the overflow tank. Inside the main tank are tubes running through the hot water solution for the engine preheat. When I rebuilt mine, the neck was highly corroded. I cleaned it up and got all the scale out of the tank. You really should locate where the leak is coming from to avoid moisture through the exhaust hole where it is possible for it to accumulate in the layer of foam between the fiberglass floor and bottom of the coach. The water could seep to the frame members, that would be no bueno.

Depending on how far down into the tank the filler neck is rusted you might be able to replace that.  Call Rudy, he might be able to help you with a fix.  I have a couple friends who did that, they cut off the old filler neck and replaced it with a rubber hose and new neck.

The Roger Berke Fillier Neck Kit is a 30 minute soluton to a leaking radiator cap filler neck leak.  Once installed, you are done with that problem.

PM me with your phone if this is of interest to you.
