Damn I haven’t noticed an increase in my bill this winter versus last, and I’m staying in a basement running a space heater 24hrs a day some days. 12 or so hours other….

53 the pipes should be fine. My basement where the pipes are running through un insulated gets into the mid 40’s a lot and never had the pipes freeze. Kitchen is through the finished basement wall to the dirt cellar(original cellar to the 1800’s part of house) and have never froze either.
