Sadly we would lose our power for 5 days to 2 weeks each winter (freezing rain would take out the lines). The moment the power went out, I would fill the containers for drinking water. I would drain the hot water boiler, and fill the bath tub with water. I then drained all the water from the lowest place in the house. This precaution meant I never had damaged pipes, or burst hot water heater. I didn't bother canning my produce because it was so cold that if the power went out frozen items would be put in the garage. Glass jars have a tenducy to burst when too cold. I saved money by having frozen stuff in the garage for the winter. The draining of the pipes didn't take too long, and when the power came back on I would turn on the water again right away. The hot water heater running without water to heat is a bad thing. I used Swedish candles to keep one room warmish. Winter sleeping bags helped with the cold. Putting bricks in the fire, and putting foil around them when we were ready for bed, kept our feet warm in the bottom of our sleeping bags. Putting up a tent over your bed could be warmed quickly. Cats and dogs kept us warm as well.
