The problem with cold weather and propane is that propane is a liquid and must evaporate into a gas before it can be used. The surface area of the top of the tank and the temperature control how fast evaporation occurs. At low temps if you don't have "enough tank" you run out of fuel, (even though you have fuel, you can't access it).
When outdoor temps get so cold there's always a number of people with useless propane equipment that can't get heat because they either undersized the tank, or cooled it too fast with the cooking demand and lost vapor pressure when they needed it most.
You had bigger than normal tanks than what people typically use so they could flow propane in cold weather. I have a 225K BTU propane burner and even in the hot summer temps, I can not run the burner at full blast off of a 20 lb tank. Too much propane is drained, the tank frosts over and then stops flowing. I'm looking for a 40 pound or bigger tank.
interesting. so maybe it is tank size. that makes more sense.
yes we rolled with 40lb tanks. never had a problem once starting and we were out in weather in the single digits.
