What my husband does on the outdoor faucets to help keep the pipes warm: Puts the beefy protectors over the faucets, with one or two of those disposable hand warmers (from Amazon) inside. Then he puts a couple of wool caps over the protector. Once activated, the hand warmers stay warm for 8-10 hours hours. Faucets are cozy; pipes haven’t frozen.
We moved from an isolated rural house in 2016. A couple years before that we installed a whole house instant-on generator. That was great! The only drawback would’ve been if the propane truck couldn’t have made it back to our place on the narrow, steep, mile-long road, with switch-backs. Once we were “iced in” for about 10 days.
wow, i’ve never been THAT long...
I put the protectors on (it doesn’t get that cold around here). But those hand warmers are a great idea! I use battery-run equipment for work - and have added insulation and a little space for those hand warmers to keep the batteries alive a little longer.
Plus the two-warmer ones in my boots!
