VIDEO: How to adjust your RV’s water temperature



Gary Bunzer, the RV Doctor, shows you how to get complete control over the temperature of the water delivered to the hot faucets in a motorhome. Many RVers complain that the water is too hot. Gary shows how a gas water heater works, then explains Atwood Mobile Products’ service kit that includes an adjustable thermostat. The kit is available as a retrofit to Atwood propane water heaters. So, swap out the original, non-adjustable thermal limit switch for an adjustable thermostat.

From Jeffrey Elmore:
Your instructions for installing the Atwood adjustable thermostat were good and easy to follow. However, you missed an important item, which I went through several hours of frustration figuring out. When changing the setting from A to B to C, etc., it is not enough to say move the indicator to the next letter. The indicator must stop IN THE DETENTE that exists at the center of each letter. If the indicator is not in the detente, the heater will not function at all because the thermostat circuit is not properly made.

Great information and video. Too bad I have a Suburban Water Heater. Did you hear that Suburban?

Suburban doesn’t hear anyone, since they are now owned by AIRXCEL, INC. You know the company that makes Maxx Fans and other RV Products. I have found that AIRXCEL is only interested in profit and very poor customer service!

We want to change out the anode in our Solitude Fifth Wheel, but cannot find the hot water heater shut off (instructions on the anode package say to do that). Any tips on finding it? We have read all the manuals but it isn’t in there.
