Oil won't freeze like water in pipes will.

I’m no HVAC guy but I do have a decent amount of chemistry - anything will freeze under the right conditions. We’re getting to some laboratory levels of cold and I prefer to be cautious over having an issue with the thing keeping the water in my pipes from freezing. I like OP’s thermometer suggestion.
