Winter camping with the Atwood XT water heater

Wondering if others have done this.

When winter camping in below freezing temps we will need to keep the water heater on during the winter months to prevent freezing.
Problem is the gas side pumps thru the propane PLUS the exposed flue pipe expels lots of heat when not lit.
I'm thinking of installing a switch on the outside of the heater that will disable the gas valve and inserting some insulation to somewhat prevent heat loss.
If I loose 120vac due to storm/downed power lines i would simply open cover, remove insulation, flip external switch then hit the gas switch inside so its back to propane.
Any others done this?
  • I think this is a poor idea. If you are running the water heater there is essentially zero risk of freezing. I have left the water heater off at -27 c (-17 f) and there was no freezing.

    I noticed no decrease in cycling time at lower temperatures. On electric, mine cycles every four hours and runs about 15 minutes, if no water has been drawn.
  • What you posted does not make much sense. Clarify what you mean.
    1. on 120, the temp of the water is about 160 degrees. There should be NO heat coming out the burner flue. There will be heat at the Pop Off valve
    2. WHY disable the gas Valve????????????? Just turn the Water Heater LP switch OFF
    3. What is the problem with any heat generated by the burner flue pipe? Doug
