    How cold before propane will stop working?

    The forecast is 1 degree for Monday night.
    Thanks! Pat

    If it gets below -44F propane won't evaporate (liquid to gas in the tank) and will cause low pressure issues in your system. We've been in the "upper" single digits without any problems - other than burning through a lot of propane!

    Looks like I will be ok.
    I have drained the water system.
    I'm running the heater anyway.
    Thank you!!

    Ive used propane in an industrial setting down to -40 and below but had to cover tank and provide external heat (heat lamp etc).

    It's good you're running the furnace - just draining the water system isn't enough. There will still be water in low places in the lines, P-traps, and the water pump. Everything would need to be blown with a compressor or pumped with antifreeze, the pump run dry, and antifreeze in the P-traps for complete protection without heat.

    We got down to -22 and still had heat and stove. The propane tanks are covered which helps protect from chilling effect of wind. I have seen some folks with electric blankets for their propane tanks, supposedly it make them more efficient. Engineers know, I don't.

    One odd thing you may think about; the gas evaporation refrigerators will quit when it get that cold. Easiest way to prevent that is to put a light bulb inside the refrigerator compartment. The RV refrigerators usually have an outlet near them to plug into, just add a 100 watt light bulb.

    This is crazy right?? San Antonio forecast for Monday night is 3-7 degrees, they're not sure yet lol! I got mine back from the dealer Wednesday and it's tucked away in enclosed storage. I don't winterize mine so the furnace is on 50 degrees and the tank heaters and water heater are on. The storage room usually stays 10-15 degrees above outside temp so other than burning some propane it will be fine. Thank goodness for 50 amp service, this is too cold for South Texas!!

    We left MN on Tue thinking we were headed to a warmer climate. 8F last night in Austin, TX. Propane is going fast.
    Rolling blackouts are a PITA, hard to supplement furnace with fireplace.

    You do realize that "wind chill" has no effect on metal objects other than to speed up the cooling effect until that object reaches the ambient temperature!

    Xrated you are correct.

    I did use the term chilling effect as opposed to wind chill. And I agree with you, the use of air movement that speeds up the cooling effect would have been a better use of words. I liken the idea I was trying to convey as the faster transfer of temperature as a result of air moving across an object. Kind of like blowing on hot soup to cool it more quickly.

    I have often admitted to being functionally illiterate. This makes it difficult for me accurately communicate ideas. Doesn't make the idea wrong, just the way I say it is.

    I apologize if anyone thinks I was misleading or untruthful. That is never my intention. And when I am wrong about something, I will admit it.
