Tank Heaters ??

[Sandrooney]

Sorry another question. We are on our way home to Colorado from Arizona. We are stopped for the night in Santa Fe , NM. It is supposed to get down to 14 degrees tonite should I turn on my tank heaters ? I am only using the main bath grey, the kitchen grey and the main bath black, nothing in the fresh water holding or rear bath. If so, no where does it tell me which switches in my panel operate which heater. Anyone know ? Will having the gas furnace on be enough without the tank heaters on ? The manual for this rig is not very helpful.
Thanks for the help. Thanks goodness for this site i would have been lost without it.

A question on top of this one is, I have three switches for the tank heaters but I have four tanks. I have two gray, one black and a fresh water tank. Does the tank heater only heat the gray and black tanks or does it heat the fresh water too?

No clue which switch runs which tank heater... at 14 degrees the best bet would be to turn them all on.

Fresh water tank; depends on where it is located. Sometimes they are located above the floor level so they would be heated by the furnace and not need the tank heater. I have also seen multiple tank heaters wired to one switch... like my current unit. I have 3 tank heaters and only one switch, an all or nothing scenario.

Thanks. So it doesn't matter if the tank heater is on and there is no water in that tank ?

The ones I have now it doesn't matter. FWIW these are fairly low powered heaters, just enough to keep the water from freezing up. I have ThermaHeat.

I don't know what brand Dutchmen uses, but suspect it is the same one. I have attached the manual from mine.
