Hey thanks for the reply! I’m not worried about the propane freezing, moreso the plumbing. I plan to be out of town on Friday and Saturday, when it looks to be coldest, and I’m concerned keep the temp on Low (~50 degrees) might not be enough to keep the plumbing safe while I’m out of town.

Any comment on propane heating systems fed by and outside tank? I’ve been keeping mine around 50, should I be worried about pipes bursting? I’m thinking more of the water system than the heating system
