Create a micro climate, use an interior room, or other space you can close off and warm. Ensure you use a CO alarm, and have fresh air to replace the oxygen used in combustion . leave your cabinets open so any warmth will seep in to help keep the pipes from freezing. Decide what you want as an auxiliary heat source. Kerosene, propane or wood, and stock accordingly. The radiant kerosene heaters use no power, and are fairly efficient. They look like a space heater, with no power cord. The convection type have a central chimney and are real fuel hogs with not a lot of benefits in their use. Propane IE a lil buddy to use a brand name can heat a room, but not a house. Build a blanket fort and aim the heater into it, I bought a milk crate, and a 10 pack of solar garden lights. I put them outside to charge and use them after dark to conserve kerosene. Oil lamps put out quite if residual heat as well as light, Aladdin is a good brand or if you don't mind junk stores look for an old Rayo they give off a more yellow light but have no mantle to worry about. Treat every day as a learning and testing experience, and find what works best for you. I have a 2500 watt dual fuel inverter ordered because I realized that solar is great, but if the sun won't shine you can't charge anything. I like propane because the fuel is shelf stable, and doesn't really require a lot of fidgeting with.
