Propane Tank Questions

[Larry Caldwell]

Was going to make the same comment. I have quite a few outdoor tanks for propane generators at remote worksites on mountaintops, etc. Never once have I had a problem with subzero temperatures. Vaporization temperature of propane is -44°F. Not unheard of in the lower 48, but not common either.

The OP was in Virginia, not a state where wildfires are a big risk. I'm not sure burying would help where fires like parts of California have had lately occur.

Big tanks probably won't chill enough to freeze, but I have had a half full 80 lb. tank freeze up on me on an 80 degree day. It was running a 6' grill and a 48" Wolf range. We had to swap tanks until it thawed.
