I want to drain the Alde boiler on my 2023 T@B 400. The Alde manual says the yellow drain valve should be in thye UP position. Where is the Alde yellow drain valve on the 2023 model? I used to access this beneath the bed on my 2018 model. Does the COLD or HOT water drain valve now operate this as well? (those 2 valves on the undercarriage beneath Nautilus panel)

The hot water low point drains will drain the plumbing system and most of the hot water tanks on the Alde and Flo system, but to drain all the water for winterizing the trailer the yellow valves should be also opened.

Whilst the new TaBs have some nice additions, the older TaBs are simpler to use and whilst they lack the refinements of the newer TaBs, sometimes simpler is better. On my 2018 TaB400 (no Flo) I can drain the hot water system, including the Alde with the Alde low point drain, I have three drains, cold, hot and the Alde water tank.
@Denny16 - the Alde drain via the yellow flapper valve is in line with the Alde cold water supply. The hot water low point drain only drains the hot water supply lines as the boiler hot water outlet exits from the top of the tank.

@Denny16 @bergger Is emptying the Alde something you guys do after every trip? I was doing that for the first year but this past season I stopped draining it and only drained the Alde using the yellow flaps when I winterize.

How is it possible to crack the boiler tank by not restoring the air gap? The purpose of the yellow valve is for both draining and safety pressure relief. I suppose the yellow valve could fail. Without doing an analysis, I would think other parts (plastic tubes, clamp connection points, etc) of the system would fail by over pressure before the boiler tank would crack. I don't know about the Alde boiler, but most pressure vessels have some sort of rating to prevent bursting to avoid injury. The air cushion is noted in the manual as a Notice not either as a Warning (injury to people) or Caution (damage to equipment).
Just curious, how did they conclude your friends boiler cracked because of the lost air gap. I would think we would see many more boiler failures if that was the case as I guess not many people restore their air gap (I never do and have 2 years of heavy service).

Yeah, the more I deal with the Alde the more I dislike it compared to "dumber" systems. They're really a demanding appliance and once you lump in all of the maintenance needed for a camper it just adds more and more layers to the entire maintenance experience. And in the end all I'm getting is a more quiet heater? Plenty of other systems out there offer "tankless" hot water for a lot less money.

Anyway as far as the air cushion thing goes. Since it is recommended I always drain the unit after each trip or if it's over a week I will do the quick procedure to re-establish the air cushion. Yes a bit of a pain to open the compartment but still only takes a couple of minutes to do. Truma combi does not require that. Hint, hint NuCamp.

For some reason I overlooked this for three seasons of heavy use on our 2020 320S and never had the tank crack. Luck or is this over hyped?
After hearing the uCamp talk I thought maybe I should flip the yellow valve, so did it yesterday as prep before leaving on a trip today. After draining the fresh and hot water tanks I refilled and ran the hot water from the sink to be sure the tank was full. I then turned the pump off and depressurized the system by running kitchen faucet (hot and cold) until the water stopped. I then opened the outside shower hot water valve and a fair amount of water drained out of it and I heard gurgling in the area of the Alde. The low height of the outdoor shower has me thinking that it may partially drain the hot water tank and maintain the air gap?
In fairness, probably 95% of our hot water use is from the outdoor shower connection.

When you look at the number of trailers produced with the Alde world wide compared to the number of issues, there are few problems. When used as directed, it appears to have little problems. If you would prefer a different design, then change it; however, your preference doesn't mean the Alde system is bad. It's just not what you want.
