Furnace using too much propane
This all happened last spring, but I never addressed the issue. Our first day/night of camping was chilly. When we got to the camper, the temperature was about 50 degrees. I started the furnace, we we...

Philh,
I think you may mean the regulator. Propane itself does not freeze until -188 C. (-306 f). It does boil at -43 (-45 f)
The other thing that may happen is that sometimes there is a lot of butane in the mix. Butane boils at -1 c (30 f). So it can be a BIG problem.
In the summer time one is better off with butane as it has 102,600 btus per gallon and propane has 91,500 BTUs per gallon
Propane is stored within the tank as a liquid, which is then released through a valve as gas. However, when temperatures drop too low within the tank, right around -44 degree Fahrenheit, the propane no longer has the ability to convert into its gaseous form. IF you are in a RV in -44 degrees F, you have WAY MORE problems than trying to run your LP appliances:B Doug
PS, In the USA, you will have a very hard time finding Butane for DOT RV tanks. Butane has been phased out for years by LP dispensers and refinery's. I know Mexico has it and I guess Canada since you are in Canada
I got sold a butane mix once in Florida.
Of course if one is running the furnace at -44 f the boiling is not going to keep up with the demand. I carry a magnetic block heat for that purpose--but so far have not needed to use it.
I use it on the generator in extreme cold.
