Keeping warm is one of the basics for survival. It starts with your body and extends outward to a room, a car, a tent or shelter, according to your resources. Anything from stuffing leaves into your jacket for added insulation, to having years worth of wood in the back yard will work. Your needs will depend on your locale, the season and situation.
For a short displacement time in the summer, blankets and/or sleeping bags and a tarp for a waterproof ground cloth or a tent will be enough. Cooler weather and a longer time will bring out the candle in a can or the 100 hour candle in your car with a window cracked open, on up to a tent with a cylinder stove and enough firewood. Saw, axe, hatchet, kindling. Seventy percent of heat transfer is through radiation, so the aluminum foil emergency blankets will help keep the radiated heat in. Twenty dollars worth of heat packets will be a dream come true for fingers and toes at night. Many last 8 to 12 hours and they store a long time. They are oxygen activated salts and iron powder, so you don’t want to puncture the packet until you need it. They are the same as “oxygen packs” used to evacuate dry canned goods. (cylinder stove)
Heating indoors can be dangerous with non-conventional means. A power outage for several days or weeks during a storm has caused many people to leave for a shelter if possible due to lack of resources. Will you have to leave your home if the power goes out? Do you have a wood-burner or fireplace that will operate electric free?
Space heaters can fill a void but are illegal in some states and locales. They have a higher danger risk than built in systems. Some of the common space heaters are the kerosene heater, white gas wick heater and the propane catalytic heater.. You will certainly want a battery operated smoke detector and carbon monoxide detector. (propane catalytic heater)(smoke detector)

For the countrified people who heat with wood, it is a two year project each year. It can take two years for wood to dry, so you are looking out a ways for your guesstimate as to how you will do through the winter, next winter.
A fireplace is probably the least efficient wood heat source if it doesn’t have glass doors and use outside air. There is the standard brick/block type of fireplace needing a foundation going to the ground, and the sheet metal type that can be installed on a regular wood joist floor. The brick type were built two different ways, with either a smaller opening or a larger opening with more radiant area exposed to the room. The latter is better. Chimneys are better if they are inside, even though they look nice from the outside with decorative rock applied. Why waste the heat? Keep it all inside.
The wood-burner was the more modular way of producing heat, with types ranging from a base burner to a parlor stove to cook stove to a wood/coal burner with a shaker. Earlier models weren’t necessarily as efficient as the more modern secondary combustion types. These burn hotter and have more air ducting to improve combustion. Some use outside air so you don’t waste your room heat. Still, they have a hot flu temp which means wasted heat.
A masonry heater is an excellent choice for burning wood for heat. It has a large thermal mass, efficient design, burns at a high temperature and will release its heat slowly, often only necessitating two burns per day of a small amount of wood. Some versions have a built in cooking area, or bake oven making them dual purpose. There are kit versions or can be more freehand made to code specs.
The tile stove or ceramic stove is a variant of the masonry heater built in many varied modular designs with ceramic tiles. They are lighter than the massive masonry heater but still burn efficiently and have good heat exchange.
The pellet stove is another heat source, but it requires electric for the auger and the fan. You must use the required fuel source, as opposed to a wood-burner, which can burn most any type and different sizes of biomass. A bank of batteries and an inverter might keep your pellet stove going for a short time in an electrical outage. You can make your own pellets with smaller home type pellet makers. They’re electric, so you would need to have the pellets made in advance.
Code permitting, or not prohibiting, the rocket mass heater is a great way to burn wood efficiently. Their efficiency is usually at least double and sometimes up to 6 or 8 times as efficient as a wood-burner. They come in many varieties. They can be small, stylish and integrate well in different environments including homes and greenhouses. They can be improvised in different ways if you were caught off guard and making do in a tight situation, or more developed in design.
If instead of going to work this morning, you had to go an additional 200 miles, to somewhere you’ve never been, are you ready to set up camp this time of year and wait out a situation? Do you have the few tools you would need to be able to call it just an extended weekend?
