Hot water tank switch

[Navodlum1]

Hello, we purchased our first Airstream. It's a 2003 Classic 30. We love it, and everything about it. I do have a question. There are two hot water tank switches in the bathroom. Which do I use and when? Thanks in advance for any help!

One is for shore power input and the other is for your propane. Not sure how your trailer was set up, but my guess would be the right is shore power and the left is propane. Propane is quicker, but if hooked to power your using propane when you don't have to.

IF it's like my 2007 one is for heating with propane has flame symbol and the other is for shore power sparky looking symbol.

Bud got me by a minute!

Thanks, I thought that was the case. As usual it's operator error, haha

I'm also scratching my head with the Fantastic fan. We have had numerous campers over the years but this fan setup seems different. Should I have both fans running at the same time, front and rear?

As pointed out, the two WH switches are for electric and gas.
On mine there is a red light between them, however it does not light unless there's a problem. I also learned that you can run both electric and gas together and heat the water faster.

That's up to you. If it were me, I'd have one blow in and the other blow out. Seems like it would move a lot of air. Mine won't reverse, though, my old one did.

When you identify the electric switch, you can put a lighted on in its place. I put a lighted one on both so it either is on, I will know at a glance. You will have to run a ground to the switches, but it is fairly easy.

Use the fans independently as needed. If part of the trailer is in shade, use that fan to blow in. One does not have to run with the other.
