We haven't used the furnace in our house yet this fall, but I've been working on getting a rental house ready since the 1st of the month. That house doesn't have a woodburner of any kind in it, so I've had to use the furnace while there a bit. The house is really well insulated though which makes us a bit jealous. Our own seems like a drafty barn at times. Our tenant of 6 years moved out and the race is on to get everything painted, waxed, and touched up so that we don't lose more than 1 month's worth of rent. Of course, on her last day in the house, the hot water heater went, so hubby has to replace that this weekend.We haven't had too much truoble with frozen pipes in recent years. The pipe closet in the downstairs bath had a few issues years ago and we bought a heat tape to keep them from freezing. If the power were to go out, we can always fill jugs of hot water to raise the temperature in the little closet or we can heat them with a blowtorch or candle.I've got a small shipment of firewood coming next week as a precaution, but we do have a lot of firewood stored and ready to go. Last night, we burned our first fire of the season.
