I like the Cpaharley's solution in the 21'. Nothing to trip over and much quieter than the strip in the AC. Had the strip in the Casita but very noisy.

The tank heater would take very little electrical power compared to the heat output of the furnace. The size of Powerblanket® for a 20-pound tank uses 120 watts at peak; an electric heater to match the heat output of an Escape's furnace would use about 2400 watts.

propane tank

Putting a heating blanket on the tank when the regulator is frozen up won't do anything. It will just increase the pressure in the tank but it still won't be able to go anywhere.

And my point being that running a furnace on propane would cost more than running an electric heater.
I doubt the propane will suffer if it gets a chill.

If you're not paying for the electricity (or only paying a flat rate), electricity would certainly be cheaper than propane. I assume that making propane heat work in very cold conditions is more about the availability of sufficient power than the cost.

The propane won't get hurt
It also won't be useful if its pressure drops too low, which is a real problem, but not at the temperatures that Escape trailers normally encounter during use.

I agree. At not much below freezing (the originally reported condition), the problem is in the regulator or another plumbing component - not a lack of tank pressure.

My buddy put in a propane fire place for the frequent power outages where he lived.
I wonder if you can get that Propane Blanket powered by propane?

I hope not, otherwise those of us who use LP to heat our homes in the winter would be in big trouble!! My home LP 500 gallon tank has seen temps as low as -30F and its never affected our furnace.

No, but propane-fueled motor vehicles normally take the propane from the tank as liquid, and vapourize it in a heat exhanger using waste heat from the engine's coolant... which is produced by burning propane. A fixed tank on an RV could be heated by the RV's space & water heating system (although I've never heard of anyone doing that), but it doesn't seem so practical for the portable cylinders used by travel trailers.

Size is important here: a big enough tank (in this case one hundred times the size of a typical Escape's cylinders) has enough surface area to absorb sufficient heat from the air to keep up with the chilling from vapourization. There are industry-standard tables specifying the tank size needed to keep up with various rates of propane consumption. A smaller tank has more difficulty, and is more likely to need help... again, at temperatures more extreme than travel trailers normally see.

I have done just that when working with Tiger Torches at -20°C, and colder, we often heated the tank up with the torch in order to get it to pressure up good enough.
