everybody should have these three essential things. First a generator. Preferably one that will run on gasoline and propane Second is one of those non vented wall heaters. You can pick up one at lowes for less then 200 bucks. Put it in room out of site if you dont want it in the living room. Heck i even made one up with a stand that was poratble. Then get yourself a 100lb tank or 5 20s. between that propane and the gas you should allways keep in case you should be able to get by for a couple days running the generator only when its needed. the heaters need no power. I have propane for heat. So i have my generator set up to run on gas/propane out of a bottle/ or my big hog. I can run the portable heater off either propane sorce. i have a line comming up in a bedroom it can hook it to or i can carry in a bottle and hook it to that and move it to anywhere in the house i need heat at that time. It will pretty much heat the whole house if its about 20 and keep it warm enough where i dont freeze or the pipes dont at below zero temps. dont cheapen out when you buy one though. Buy a generator at least 5000 watts and buy the biggest heater on the shelf. Wood stoves are great to for times like that but just make sure you dont buy one that relys on electricity to run. Mine has a water pump and a electric controlled damper to control temps. I can bypass the damper but it still needs to pump hot water to the heat exchanger.
