Alde shower not hot

I am sure this has been posted but I couldn't find a good match to my problem.

I have a 2018 33ft Classic with a Alde heat system. We love the heat and how even it is. The sink also gives off really hot water!

But unfortunately our shower is kind meh and just a little luke warm. We are using the shower booster (e.g. hit the plus sign all the way on tre shower icon and wait 10-15 minutes)...it's still not very warm.

We love hot showers...the temp knob under the dinette is turned to max. What else should I check?

Thanks

The first thing to check is the water temperature after you’ve hit the boost. We hit the boost & click the 2kw button.

Hit the settings button (bottom right) then the down arrow a few times - click the service menu button. That will show Glycol & Water temperatures.

Ours has gone as high as 165 degrees for both.

It can take up to 30 mins to hit the maximum high temperature. My wife watches the temperature before getting in.

She still bitches about the temp not being hot enough, but I think it’s hot enough to melt my skin off. Lol

We have a 1.75gpm shower head. I was thinking of switching to higher flow shower head hoping that might help her.

But doing that will at least let you know system is working at the unit.

The shower knob might be adjusted to reduce scalding. You can adjust that so that more hot water is delivered in the shower by removing the handle and adjusting the device.

If you have a 3020 unit, make sure the alde flow is checked off on your control panel. I think you may have a 3010 unit though.

By the way, Is this a new problem or has it always been this way?

Oh great, I will check the temperature next time. Right now it does appear hot at 122 degrees without boost.

I will check the shower head. No idea where the setting is for antiscald.

This is a new problem to us. We got the trailer used in Feb. Our 30ft bunk didn't have this problem but it wasn't alde.

Someone mentioned a mixing value in previous forums, does anyone know the location if that?

Are there any schematic for the 33ft for pipes under the dinette? The ones in the manual are not exact enough for my taste or maybe I missed it somehow.....

Hi

There is a *lot* of info on various tweaks to the 2017 and 2018 Classics floating around on the forum.

The mixing valve is next to the 3010 unit, under the dinette seat. You can adjust it to (essentially) not mix hot and cold water. The water at the sink will track that adjustment.

If the water at the sink is much hotter than the water in the shower, then the shower valve is the culprit. It could be an adjustment, it could be crud in the valve or pipes.

The 3010 system is not known for delivering long hot showers. This is what got the 3020 "boost heater" added to the mix. If you get it adjusted for "max hot", your shower lasts a few minutes. Then you go to nothing but cold water ....

HW mixing valve is under the dinette seat nearest the door (the side facing the stovetop), it sounds like your issue is at the shower valve. Unscrew the handle flange and adjust the water temp upward. Airstream says the safe temp for the HW is 120. Ours has plenty of HW for a nice relaxing shower. Just let the shower boost run for about 15-20 min before hand; also select both gas and electric 2.

There are 2 things you can try, if you haven't already. I had to do both before having consistently hot showers.
  1. "Over adjust" the mixing valve under the dinette. You can find instructions in other threads. (e.g. the first post in this thread is a nice description.)
  2. Adjust the mixing settings in the shower valve. This Youtube video shows how.

Good luck!

My mixing valve is set much hotter. It gets past 165, really hot. Had to take the ‘black hat’ off the Alde mixing valve and turn the screw to get it that hot. Then I adjusted the shower anti scalding ‘valve’ which is really just an orange tab on our 2019 classic. It was at 3 o’clock. Adjust it to 6 and keep adjusting until you get it the way you like. The shower handle is set so you will not scald yourself if you take a shower at full hot. We will scald ourselves if we do that so we put the handle part way between hot and cold. That mixing at the shower handle, combined with the Alde mixing valve gives us more hot water than we have ever needed. Attaching some pics.

The shower handle escutcheon unscrews. The handle fits on a square peg and you can unscrew it by holding the square peg and unscrewing the screw in the middle. Then adjust the orange tab which sets the hot cold mix.

Does the shower handle just unscrew? Mine goes from - off to hot - but doesn’t feel like I can unscrew it.

The shower handle has 2 parts. The handle and the escutcheon that is against the plate attached to the shower wall. The escutcheon does unscrew and the handle will come off with it.
