Shelter & Warmth
Roof, heat, dry.
Three months of winter is a thermal-envelope question. Insulation, air sealing, and zone heating decide the fuel bill and the failure mode.
The shelter & warmth domain →A 3-month winter-readiness system — deep pantry, redundant heat, water security, and the routines that make a long cold season uneventful.
Three months of winter-storm readiness is no longer a checklist. It is a system. The household has redundant heat, a deep pantry, water security, and a maintenance routine that runs from September through April. This is the posture that treats a 10-day outage as inconvenience, not crisis. The work below is the system, the routine, and the inventory it runs against.
Every event–duration combination weights the nine domains differently. Here are the two or three that decide the outcome for this one.
Roof, heat, dry.

The shelter & warmth domain →When the grid goes.
Redundant heat sources, redundant fuel storage, and redundant electricity. Three sources, never one.
The power & light domain →Eat well, store smart.
A 3-month deep pantry is a real inventory system with rotation, not a stack of buckets in the basement.

Roughly 740,000 calories — about 90 days × 4 people × 2,050 calories. In practical terms: 200–300 pounds of rice and grains, 100–200 pounds of beans and legumes, 50–100 cans of various proteins, freeze-dried produce and dairy, cooking fats and salt. A real deep pantry is organized by category, dated, and rotated quarterly through normal household meals.
A modern propane heater rated for indoor use, ducting a single room of 200–300 sq ft, with the doors closed and the household sleeping in the room. Roughly one 20-lb propane tank every 2–3 days at moderate run. Pair it with battery-powered CO detectors and you can run the household out of one room for weeks.
For a household running essentials beyond extension cords, yes. A transfer switch — manual or automatic — connects the generator to the house panel and lets you power circuits (furnace fan, well pump, fridge, lights) without running cords through windows. A licensed electrician installs one in a day; it is the difference between a backup that works and a backup that frustrates.
