Shelter Heat

1. Seal drafts in one main sleeping/living zone first.
2. Create layered bedding and clothing system.
3. Choose heat source and verify ventilation path.
4. Set nighttime safety checks and watch rotation in severe cold.

• Block window drafts with plastic, blankets, or foam board
• Use rugs/cardboard to reduce floor heat loss
• Close unused rooms and doors to shrink heated area
• Sleep in inner room or tent-inside-room for thermal efficiency

Every draft you seal is fuel you do not have to burn.

• Mistake: heating whole building. Fix: create one heated core zone.
• Mistake: drying wet gear indoors without venting. Fix: moisture control schedule.
• Mistake: no overnight temperature checks. Fix: min/max thermometer and check times.
• Mistake: open flames near bedding. Fix: 3 ft clearance rule.

Drill 1: Freezing Night Simulation

1. Run full overnight setup with backup heat ready.
2. Track zone temperatures every 2 hours.
3. Measure fuel used.
4. Goal: maintain sleeping zone above 55°F safely.

Drill 2: Heater Failure

1. Simulate primary heater shutdown.
2. Switch to secondary method in under 10 minutes.
3. Execute insulation and occupancy consolidation.
4. Goal: prevent rapid temperature crash.
