Monaco 2009 Aqua Hot System

Hello team. I’m in the process of re filling my aqua hot antfreeze reservoir. Through a number of mishaps.. starting with Sani flush cleaning my black tank and well pump kicking on.. creating a leak under 1st bathroom sink ( blew the top off anti siphon separator valve) … me killing all power sources after steam and the sound of boiling liquid out under the aquahot unit. .. shutting off water and somehow not thinking aquahot was effected by it.. well. Without water to diffuse/ absorption of heat.. that liquid is all that was left to I boiled perhaps all the boiler anti freeze from the reservoir. After contacting aquahot .. I was advised to use a propylene glycol GRAS .. in the book too… so I did the Amazon purchase. There is a fluid tank low re set button.. or toggle on /off aqua hot toggle switch. I ordered 4 gallons. Advised that once the tank recognizes higher levels of heat transfer fluid aka, anti freeze, it will reset. . Here is where it gets concerning. I have to take divider out of bay. Electrical read out board is attached. I need to shift it outta the way. Then a bleeder valve with a set screw needs to be opened. ( familiar to anybody?). That allows tank to refill and bleed off air. I have a small over fill hose attached already. .. it’s not known how much fluid got boiled out but I know the reservoir is empty. So.. a gallon at a time will be added. When it gets to normal operation temp. …if it does….I’ll check where the level is on the reservoir. .. any ideas or suggestions… based on real experience with this is appreciated and taken under counsel. Thank you…oh yeah.. worse case scenario, I have the numbers to 3 aquahot service shops in the Idaho falls area. Might warrant a trip to service system.

Did you pump high water pressure into the coach fresh water system as well as the black tank flush?

The AH is not really a "boiler" it should never get to boiling/steam temperatures on either water or glycol side.
AH may have failed to finish to slight cooling cycle and stir pump quit causing extra expansion .
Do you have a fresh water inlet regulator? I strongly suggest getting a decent one if you run on city inlet.
If you need yellow boiler fluid Camping world was just the cheapest by far this month.

Oh yeah.. what happened was Iím was using the well to clean black tank .. I wasnít running high pressure at all but the pump decided it would kick it up 10 notches. Thatís when all hell broke loose. Literally. The water is a high iron content so I get my drinking water from a real filtered ststem and I have a seoerate filtration beyond that. I will get a pressure regulator that is set to no more than 42#? Now Iím waiting on fluid.

That may have been the cause.. Iím not a aqua hot guy, in fact only owned this coach for 4 months. Iím still learning so much! I am getting a pressure regulator for sure. I called aqua hot company headquarters and spoke with a fellow who understood my situation and even though it was a guarantee my system would work but he said he would highly doubt it wouldnít recognize fluid again.. ( low fluid shut off occurred) and it would work just fine. He pointed me to Amazon Prime for fluid so I bought 4 gallons. He said itís a 5 gallon tank so if there is any fluid left or not, 4 would get me a great start and I could top it off after I get it going. He also gave me the numbers of three aqua hot mechanic/ dealers in Idaho falls area. Itís 4 hours away and if need be.. Iíll make the trip. I have some friends there anyway. This fluid is not cheap but it is that actual Aqua hot product. Iím going to change out the fuel filter also. There is a date but I cannot read it. So .. while Iím on it.. gonna do that too

You can find vids of how to do annual service. I was going to post link Amazon had diesel nozzles for only $7.26 I grabbed 5 then price went back up to $27ea so that's about the going rate . You have to be extra careful with hinge bolts as not to over tighten torque spec is very low. Newer AH have combustion chamber gaskets, my chamber just pulls out no gasket.You need wire brush and shop vac to clean heat transfer chamber. Vids use hose pinch pliers or clamps to pinch fuel lines when changing filter or removing burner fuel lines. I just move burner to the side. If yours has radiator cap take a close look at seals and little return valve. AH seems to be extra rough on radiator caps compared to cars. I use a lever release cap it takes a little stress off the radiator neck to remove or install. Not to scare you some AH necks have started to leak due to light solder job. Many owners had split return hose near the cap. When mine split I used a better quality coolant/fuel line but needed a hose union barb ,as I couldn't/didn't want to try to force reinforced hose on plastic return tank barb so last foot or so is old the lighter hose.
