A winter outage can become a heating emergency long before the lights return. Rural homes may also lose a well pump, furnace blower, boiler controls, communications, or road access at the same time. The safest plan combines heat conservation, approved equipment, working alarms, and a decision point for leaving.
This is not the time to invent a heater from a grill, camp stove, oven, candles, or a machine with an engine. Fuel-burning equipment can create carbon monoxide, a colorless and odorless gas that can incapacitate or kill. Fire risk also rises when households improvise heat and lighting.
The Short Answer: Do These Things First
- Account for everyone and check official outage, weather, and emergency information.
- Close off unused rooms and choose one safe living area.
- Add dry layers, hats, socks, blankets, and sleeping bags before adding another heat source.
- Confirm smoke and carbon monoxide alarms are working.
- Use generators and heaters only as their manufacturers and safety authorities direct.
- Leave early for a heated location if the house cannot remain safe.
Prepare the House Before the Storm
Service the primary heating system on schedule and learn which parts require electricity. A gas or oil furnace may still need power for controls and a blower. A boiler may depend on pumps. A wood stove only counts as backup heat when it is properly installed, maintained, supplied, and used by people who understand it.
Test smoke and carbon monoxide alarms and keep the batteries required by their instructions. Put flashlights and headlamps where people can find them. Charge power banks. Store blankets, warm clothing, and necessary medication together. Identify a heated destination and at least two routes to it.
Households with infants, older adults, people with disabilities, or anyone dependent on powered medical equipment need a specific backup plan. Register for local alerts and, where available, discuss outage planning with the utility and medical provider before bad weather.
Make One Room Easier to Heat
Choose an interior or naturally warmer room that can hold the household without blocking an exit. Close doors to unused spaces, draw curtains after sunset, and stop obvious drafts with removable materials that do not cover combustion-air openings, heaters, or exits. Let sun in through suitable windows during the day, then close coverings at night.
Do not seal the home so tightly that approved fuel-burning equipment lacks required ventilation. Never block a chimney, flue, or manufacturer-specified air supply. If you are unsure how installed heating equipment vents, have it inspected before winter.
Warm People Before Warming the Whole House
Wear several loose, dry layers. Add a hat, warm socks, and footwear. Change damp clothing promptly. Use blankets or sleeping bags and keep children away from spaces where bedding could contact a heater or open flame. Eat regular food and drink fluids if safe water is available. Avoid alcohol, which can interfere with judgment and the body's response to cold.
Check one another. Shivering, confusion, fumbling hands, slurred speech, drowsiness, or unusual behavior can signal a cold-related emergency. Seek medical help and follow emergency-dispatch instructions rather than trying to diagnose the situation from an article.
Use Portable Heaters Exactly as Directed
Only use equipment approved for the location and fuel. Keep combustible materials away by the distance in the heater instructions. Put a heater on a stable surface where it cannot tip, and keep children and pets out of the clearance zone.
The CPSC advises plugging an electric portable heater directly into a wall outlet, not a power strip, and never running its cord under rugs or carpeting. Do not leave portable heaters operating unattended or while people sleep unless the manufacturer explicitly permits that use and all safety requirements are met.
Never use a charcoal grill, camp stove, or outdoor heater indoors. Do not use a kitchen oven to heat the house. A flame that appears to burn normally can still create carbon monoxide and fire hazards.
Keep Portable Generators Outside and Far Away
The CPSC says portable generators belong outdoors only, at least 20 feet from the house, with exhaust directed away from windows, doors, vents, and other occupied buildings. A garage, shed, carport, porch, basement, or crawlspace is not a safe generator location, even with an opening or fan.
Keep working carbon monoxide alarms in the house. Use only heavy-duty outdoor-rated cords sized for the connected load and free of damage. Never plug a generator into a wall outlet. A connection to household wiring requires correctly installed transfer equipment. Shut the generator down and let it cool before refueling, and store fuel outside living areas in approved containers according to local rules and manufacturer instructions.
Treat Every Carbon Monoxide Alarm as Real
If a carbon monoxide alarm sounds, move everyone to fresh air and call 911 or the fire department from outside. Do not search for the source first or reenter until authorities say it is safe. Headache, dizziness, weakness, nausea, vomiting, chest pain, or confusion can occur with carbon monoxide exposure, but do not wait for symptoms or rely on a household alarm display to decide that exposure is harmless.
Protect Water Systems Without Creating New Hazards
Open cabinet doors around vulnerable plumbing where appropriate, but move household chemicals away from children. Know the location of the main water shutoff. If the house will be unheated long enough for pipes to freeze, follow instructions from the utility, plumber, insurer, or local authority about shutting off and draining systems. Boiler, hydronic, and fire-sprinkler systems may require professional handling.
Set a Leave-Early Threshold
Decide in advance what will trigger relocation. Possible triggers include an indoor temperature that the household cannot safely tolerate, a failed alarm, dwindling safe fuel, worsening road conditions, a medical-equipment deadline, signs of frozen plumbing, or an official evacuation order.
Leaving while roads and vehicles are usable is usually easier than waiting until the house is dangerously cold. Take medication, chargers, identification, warm clothing, water, and the household communication plan. Tell the trusted contact where you are going.
Common Questions
Can I run a generator in an open garage?
No. CPSC guidance says never use one in a garage, basement, shed, crawlspace, or other enclosed area. Operate it outside at least 20 feet from the house with exhaust directed away.
Can I use the gas oven for heat?
No. Cooking appliances are not space heaters and can create carbon monoxide and fire hazards.
When should I leave the house?
Leave before anyone becomes dangerously cold or roads become impassable. Use the household's preplanned thresholds and follow local emergency instructions.
