Shelter & Warmth

The house you already live in is the shelter you already own. The question is whether your house works when the systems that normally run it — heat, water, power — stop running. Most fatalities in extended emergencies happen inside houses, not outside them, and most of those deaths are from cold or carbon monoxide. Shelter and warmth is the domain where the difference between a working plan and a guess is measured in body temperature.

The system: dry, warm, together

A complete shelter plan rests on three priorities, in order.

Dry is the building envelope. Roofs that do not leak, windows that close, doors that latch. Water intrusion is what destroys housing — slowly through rot, suddenly through storm damage. A house that cannot keep weather out is a house that cannot do anything else for very long.

Warm is the ability to hold survivable temperature without the primary heat source. Cold kills inside houses every winter. A backup that has been tested in real conditions matters more than one that exists in theory.

Together is the discipline of consolidating the household into the warmest, smallest, most defensible space rather than trying to maintain a five-bedroom house at habitable temperature. A family in one room with a propane heater and sleeping bags lives. A family spread across three floors trying to keep the whole house warm exhausts the fuel and the family.

The four levels for shelter

72 hours. Sleeping bags or mylar emergency blankets for every person. A way to seal a broken window with plastic sheeting and tape. The knowledge of which room of the house is warmest with no heat (smallest, fewest windows, most interior).

Two weeks. An indoor-safe heat source — a propane Mr. Heater Buddy with the catalytic safety, a kerosene heater with proper ventilation, or a wood stove already installed. Fuel to run it for at least seven days. Real sleeping bags rated for the worst cold you expect.

Three months. A whole-house alternative to the primary heat system. A wood stove with a stocked woodpile. A propane reserve in a tank that lasts months, not days. Insulation reviewed and improved where it leaks. Window coverings that hold heat at night.

Long-term. Off-grid heat as primary, not backup. Wood, solar thermal, masonry stoves, root cellars. The house is engineered for the climate it sits in, not for the grid that powers it.

First moves

1. Identify the warmest interior room. The room that holds heat best with no input — smallest, fewest exterior walls, most interior, ideally on an upper floor. Mark it as the consolidation point.
2. Buy mylar blankets. Twenty of them for under thirty dollars. Distribute them to closets, vehicles, and the consolidation room.
3. Buy a Mr. Heater Buddy and a one-pound propane canister. Read the manual. Test it outdoors first, then test it indoors with the carbon monoxide detector running. Confirm the auto-shutoff works.
4. Stock plastic sheeting and duct tape. A roll of six-mil plastic and a roll of real duct tape will seal a broken window through a storm. Cheap, indefinite shelf life, takes one closet shelf.
5. Verify your CO detectors work. Press the test button on every one. Replace batteries on any that are silent or quiet. CO kills people who survived everything else.

Common mistakes

Burning the wrong fuel indoors. Unvented kerosene heaters in poorly ventilated spaces. Charcoal grills moved inside during a storm. Gas generators run in attached garages. Carbon monoxide is colorless, odorless, and patient. The mistake is fatal.

Fuel stored badly. Propane and kerosene live outdoors or in detached structures, not in the basement. Gasoline does not live indoors at all.

One heat source. Households that rely on a single heat alternative — a single propane heater, a single tank — are one failure away from a problem. Two methods, one tested.

Sleeping for the temperature you wish you had. Sleeping bags rated for forty degrees are useless at twenty. Plan for the worst night your region can produce, not the average one.

Where to go next

The winter storm outage playbook covers the most common shelter-and-warmth scenario in step-by-step detail — what to do before, during, and after a cold-weather grid failure. The two-week heat plan is the standing capability behind it: the warm-room strategy, the insulation sequence, the fuel math, and the carbon monoxide rules. Start with the playbook, then build the plan around the gaps it exposes in your own house.
