Frozen pipes

[Biggd]

I used to have a 3-season camp in Alton Bay back in the 80's. My next-door neighbor built his camp with the kitchen and bathrooms over a corner of his house. He had everything draining into one small, insulated enclosure in the crawl space which he heated with a small propane wall heater. So he would just drain the pipes down to that room, put antifreeze in the traps, and just heat that area, very efficient!
