I'm skeptical that cold temperature is affecting the propane to the point where it is not flowing. And I doubt you need to heat trace the lines. From http://www.propane101.com/propaneregulatorfreezing.htm
But if you have any doubts about this, I suggest you contact your propane dealer. If cold weather is actually a problem, they will be aware of it and know how to deal with it.
I also highly doubt that there is water in the propane. It is possible that the regulator is malfunctioning. Again, this would be a good question for your propane dealer as they would probably be the right people to talk to about getting it checked and/or repaired.
This implies that propane is at subzero temperatures during normal operation.As the propane passes through the regulator, it expands (resulting in sub zero temperatures) and causes the regulator to gradually reach the extremely cold temperature of the propane vapor passing through it.
