On my 2018 30' with a 3010 boiler they put the Alde Flow between the boiler and the outside wall. Snug but it works. No difference in dinette seat heights.

He said it seemed like a lot for the loop, but the registers are multi-pass, not just straight through. But, there are two model years past the '17s we have, so who really knows.

Any of you over-acheivers out there could really help the rest of us '17 DIY-ers get 'er done with some shade tree stories.

What I've used for make up and plan to use for replacement. It matched the MSDS from Alde for the blue stuff. Pricing is going to drive the concentrate or one gallon premixed.

Hi

In this case, if you are going with a concentrate, mix it with distilled water. Trusting the local tap water to be devoid of something nutty is not a good idea. The local grocery store should be well stocked with gallon jugs ....

Absolutely, and everything including hands needs be clean, clean, clean when refilling.

Hi

One unanswered question - do you do a flush before you do a refill? If you flush, what do you do it with and how much of it?

Yes, I know people who get obsessive about oil changes and can't understand why the rest of the world does not do a rinse step.

Had my system flushed by my local AS dealer and Alde, DI water was used. Not sure if a flush is recommended or required prior to replacing glycol, Spencer at Alde could answer this question.

I’m so confused by so much information. We’ve had our 2018 30’ Classic for about a year and a half. We’re currently in FL during a real cold streak. When the heat is on we’ve always heard some “gurgling”. Now when the heat comes on it sounds like it’s raining in various areas. Wakes me up at night. Is this normal?

(Ms. Lauri, coffee alert)

Well, it could be normal if you are a light sleeper

The gurgling you might hear when the circ pump runs for heat is the expansion tank in the cabinet above the toilet (circa 17). If you top it off, less gurgling, but still normal. Sort of a cold weather ambiance to let you know all is well with heat.

The raining sound is new; could be an air bubble in the register near your bunk. AS told me they were multiple pass registers, hence the 5 gallon volume for a 70' loop. So, this will mean 3 passes thru each register, 2 internal elbows, and perhaps you hear the ambiance of the Alde waterfall.

Or it was just raining outside.

The real question was were you comfortable (temp wise)?

James, Your camco link did not work when I tried it??
Yup, looks like they dropped it. I've bought it at RV shops at about $15 a quart concentrate. It was CAMCO 35116 Boiler Antifreeze Concentrate.

smkovalchik, ditto what James said. Try topping off the tank first then maybe bleed the valves nearest to your pillow. (Although I haven’t ever heard the gurgling in the bedroom I can hear the tank when I’m sitting at the dinette.) If you’re still hearing the sound after toppling of the tank you may need to bleed all the valves but I’m guessing that just filling the tank will do the trick.

If it's really quiet out and you are in the bunk on the side by the bathroom, you can indeed hear the gurgle in the bathroom tank from bed. Indeed, we keep the bathroom door open at night due to multi dog traffic issues in the hall. That may have some bearing on the noise level.

I think I need to clarify our issue. The gurgling isn’t just in the bedroom and certainly not under my pillow, it’s coming from most of the heating areas, living area and bathroom. The solution is to have it serviced when we return from a Florida.
Thanks for everyone’s help.

Gr8, please post the "rest of the story" about the rainfall noise. Thx.

I also have heard that sound. Mine happened once under the sink area. To me, it was like a hose was pinched and the fluid was bubbling and rushing past. Your description that it sounded like "rain" seems very appropriate.

I am not an Alde expert, but I believe when the air gets trapped in a large bubble in the hose, the fluid is somehow forced by while the air bubble remains in place causing the rushing sound. I've bled my system four times since then and I have not heard that sound again.

You may have excessive air in the system.

So here are some basic heat transfer and fluid flow ideas. Your circulation pump (all circa 17) will run even if fluid cannot flow due to a restriction, air or otherwise. Just runs and beats up the water; think vacuum cleaner with your hand over the nozzle. On my trailer, the flow goes clockwise from the boiler around the trailer, expansion tank is on the suction side of the loop, at the bathroom, in line with the biggest bubble catcher, the towel rack. I suppose if the rack was, not warm, and nearly full of air, the pump with speed set at 1, like mine was, might not be able to push against that bubble uphill from the bedroom and displace the bubble, backwards against flow forward. Little to No heat from registers.

Have you tried the easy vent at the top of the towel rack? Could be a game changer.

If you look at the side of the circ pump, small surface switch, set to 3 or 4? Under the forward dinette seat.

For air in the registers, if they are 3 pass, and the first pass is on top in line with flow direction, I could imagine a hot fluid flow stream-bubble interface, with fluid trickling through the passes, and a sound like rain. Some heat, but far from design output. I haven't verified multi pass yet, or that might be an upgrade after 17. Individual registers have vents on one end or you can follow the manual instructions and tilt the trailer full up and down (Rig ship for angles and dangles.) and hope the air travels around and works its way to the auto vent valve of the boiler, hope it opens as designed, and hope it doesn't stick open and drain your system. Have I mentioned how hope isn't a plan or solution I recommend.

You may need to just burp your system a bit. Depending on the dealer, you may already know more than the actual technician assigned to your service. Or not, and it will be an easy service and just charge for the Alde fluid.
