Can I safely insulate the feed line from my fuel oil tank to my furnace? For some reason that I do not understand, my fuel tank is positioned on the windward side of my house. (Not my doing) The feed line is exposed for about 8 feet outside, and then across the entire width of my home to the furnace! ( go figure) We have been blessed with extraordinarily warm weather this season, but the wind has been picking up and cold is beginning to settle in. I don't know why I didn't think about this before, but that exposed stretch of line is likely to freeze from the moving cold, etc. Had it happen at the house we used to own several times before we moved the tank. Since the tank is currently full, moving it is not a viable option at this time. Can I safely insulate that line with pipe insualtion like we would use for water pipes? Or should I stick with old towels, bubble wrap and duct tape? Please help quick. Old man winter is rearing his ugly head and I want to beat him to the punch!
