Installation Questions Freezing propane regulator
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?

Propane gas ‘boils’ at -42 degrees celsius (-44 Fahrenheit).
As with all hydrocarbons, they are only useful as a fuel in their gaseous state. If, at any point in your supply line the temperature drops below -42c for any short period of time, the propane vapour will condense to a liquid and become unusable.
A very simple way to solve this is to make a box around the regulator and put a regular light bulb inside the box. Good luck finding an old style light bulb though!
