    Hmm

    I lived in the city, but had friends and cousins that lived in the country. They used Butane for heat, hot water and cooking. The storage tanks came in 150 to 200 gallon tanks, above ground. If that was butane, how did the butane come out of the tank when it was cold? They are called propane tanks now. How do butane cigarette lighters do up north? Just wondering. Roy

    Roy, you put them in the ground in cold regions. Or to just get them out of the way. If a lighter is in your pocket, it will work.

    Hmm Yeah James, but here they are above ground

    It gets cold here every once in a while. I have seen it get into the 20's here before, for a day or two.

    They use a mix of propane, butane, and a couple other things here. Keeps it flowing in winter..

    You still see iced-up tanks when it gets really cold out.

    Then a good question would be at which temp does propane stop moving? This would mean the mass of the tank wold need to reach the temp.

    I have had the hand held bottles stop working in the teens.

    I don't think it actually stops moving.. Propane boils about -40. Butane boils about +30.

    I think the problem is that the tank doesn't have enough surface area to boil very much of at the lower temperature.

    I'm sure somebody will be along soon to enlighten us.

    Hmm Ralph

    Butane will be a liquid at 50 psig at 100 degrees F. Propane will be a liquid at around 250 psig at 100 degrees F.

    I don't know nothin' 'bout gas but........

    Here's a P/T chart for R290 (Propane).

    It would seem logical that the question to consider here is what is the lowest tank pressure allowable for a system to function? If say, you need 15 psig at the tank to make the regulator work and supply proper gas pressure to the furnace or appliance, then these things would work at around -21F. No?

    I found out a little more about butane

    Yes, They did use butane here in the South up until the mid 70's. And Ralph was right. Butane boils at 30 F at atmos. pressure. Propane boils at -45 F atmos. pressure.

    Hey ice

    I guess I will find a P/T chart for butane. Thanks Roy

    Back when you were a boy, they had just discovered propane.
