Air in hot water line

LauraC · August 15

Hello … 2025 T@b 360. On my most recent trip I had a lot of gurgling when turning on hot water - especially at kitchen faucet. Cold water was fine. Some air came out when opening hot water drain valve post trip. I tend not to run the hot water very long when I first turn it on as I don't like having water run down the drain unused. But I think that might be the solution … run it until there's no air when I first get it going. Also … I turn on the hot water at the Alde panel with each use. I don't leave it turned on. Any thoughts would be much appreciated! (I just want to make sure I'm using the hot water in the most efficient manner)

Extra & sometimes difficult to clear air in the HW side of the water system is very common. On my TAB I use house (city) water before my trip to fill all the trailer water lines . . . this allows draining the gray tank if a lot of water is needed to clear all the air and no air issues at the final camp site.

. . turn on the hot water at the Alde panel with each use . .

Not clear on your meaning of "turn on" as:

If the Adle is fully off, then you will need to wait 30+ minutes for the Alde to heat the water.
If the Adle is on (glycol is hot) and you are just using the Control Panel HW off/on/boost then:
1. Off HW is below typical ideal usage temperature
2. On HW is at ideal usage temperature (you will have to wait a bit for Alde to reach temperature)
3. Boost, no change in HW temperature. Alde will stop cabin heating {if active} for 30 minutes so all the heat energy goes to HW production.

MuttonChops … (great name, BTW) … thank you! Good to know that this issue is common. And, getting the lines filled before leaving home is a good idea. And then dumping the gray water so I start with that empty. As for "turning on" the hot water … thanks for the bullet point info. I was aware of some of that but not all. I guess my question was … at home, the hot water is always available. It's tempting but probably ill-advised to turn the hot water to "on" (as opposed to off or boost) at the Alde panel so it is ready all the time. Seems like that might be a strain on the system. I usually keep things in the off position when not needed - including the Alde (when I don't need hot water, cabin heat or AC, for instance - I just turn it off)

@LauraC Alde claims the system is designed for 365/24/7 safe operation so user cycling on/off should not be a factor for system reliability.

For myself when hot weather camping I keep the Alde fully off. On shower day I'll fire it up an hour before showering, for light dish washing I'll just heat some water on the stove. Keeping the Alde off saves propane when dry camping and might help to keep cabin slightly cooler as the Boiler does radiate heat.

When shoulder season camping my Alde is on whenever I'm in the TAB. When winter camping (remember these are not four season campers) it is on 24/7 except for travel days. During those shoulder/winter adventures I do use the Boost Function at shower time.

@MuttonChops … thanks so much! That is exactly what I wanted to know.
