Heating Without Electricity: Safe Ways to Stay Warm
A winter blackout is the most dangerous disruption scenario. Good news: heat retention beats heat production. Insulation first, then safe heat sources.
Rule #1: one warm room
Choose the smallest room, ideally south-facing. Seal doors with towels/blankets, cover windows with foil or blankets at night.
Layer like outdoors
Thermal underwear, hat (most heat loss is through the head), sleeping bags, shared body heat. A 3-person room with layers holds 15–20°C above outside.
Safe indoor heat (with caution)
Only heaters explicitly rated indoor-safe (catalytic/oil radiators), ventilated per manual. NEVER: charcoal grills, gas camping stoves, generators — carbon monoxide kills silently. Get a CO detector first.
Hot water bottle economics
A 2 kW kettle boil gives hours of bottle warmth. Fill bottles before the outage if warned; water heaters often hold heat for 1–2 days.
Cooking = heating
One pot of tea or soup heats the room's air and you. Cook your longest-storing food first during outages.
Community beats solo
Neighbors with fireplaces, heated public shelters, family bundled in one room. Cold is survivable alone; warmth is easier together.
