there is no way I can fit into the freezer to watch what's going on. ๐

It's tough to simulate freezing conditions in order to test this idea -- it gets down to the high 50s at night where I live!

DW suggests a 12 volt LED bulb, like the ones in the inside fixtures. (The bulbs emit some heat and use almost no wattage.) This would be inside an enclosed space, right next to the outlet tube coming out of the fresh water tank, and we would turn it on and off manually. I would monitor the tank temp to see how much this affected the water. Might not be enough warmth. But all I want is minimal effectiveness, not hot water!

Got it. I know of those tiny little "personal heaters" and I never would have guessed anyone was using those for an anti-freeze device.
We've had a few people try them at work (indoors...heated office) and they were a joke.
Please dont take offense, but I cannot believe you've found them effective within the unsealed underbelly of an RV to prevent freeze ups. The air temp rise math doesn't work at all, and if you add any air movement from the outside, its simply impossible.
There has to be more to this story.

I happen to use a 200 watt heater for my waste tanks. That's a little less than 700 btu's. The conversion number is 3.41 btu's per watt.

Hopefully he meant 700 wat max?
