Heading off to bed now. It’s 6ºF outside, with a pretty good breeze too. Still, the bedroom is about 45º. I have a remote thermometer sensor wedged in the one set of pipes that I have concerns about freezing (in the cellar)– it’s 42º in that spot. I ran a little warm water down that drain just in case. I’ve been brainstorming ways to keep pipes from freezing other than turning on the furnace. Have thought of at least four so far– a future post. Ideas?
