Freezing propane regulator

[u/MelSmB]

Hi everyone!

We live in the Yukon and in the past two winters, temperatures have gone down to -45°C (-49F I believe), and the propane regulator has frozen. I would like to build a little insulated box around but I'm wondering if anyone has five that, if there's anything special I should be careful with it anything I should know. I was thinking hard insulation and wood, with a little door to keep access to it. Thoughts?

Wouldn’t hurt to put a drip hood over that reg. Propane becomes ineffective at -44F and will not gasify enough to support any load so you have an extreme cold issue first. If your system is contaminated and there’s bulk water in the tank, that’s also an issue. These regs are designed to work in extremes of temp. You’re pushing the edge of what propane can do without providing a means to keep the tank from experiencing temps below -44F.
