I have been doing it for years with no problem.

I do that as well and I live in Ottawa, Ontario, the 'second coldest capital' city in the world (after Moscow)

I live in Yukon. My house is heated by propane (well, until -40C, when it gels. Then I have to use wood.) The tank is outside, so your situation should be fine. BTW, while Ottawa is the 2nd coldest, it is Ulan Bator, Mongolia that is coldest. Ottawa is colder than Moscow! And to think I moved to Yukon from Ottawa.... (-10C as I write this. Brrrr!)
