Space heaters can be a lifesaver during a furnace outage, but safety is key:

  • Placement: Keep heaters at least 3 feet away from furniture, curtains, or anything flammable.

  • Supervision: Never leave them unattended or running overnight.

  • Type: Opt for modern, energy-efficient models with automatic shut-off features.


2. Layer Up and Bundle Up

Dressing in layers is one of the simplest ways to stay warm:

  • Clothing: Wear thermal underwear, sweaters, thick socks, and hats indoors.

  • Bedding: Use extra blankets or thermal comforters to stay warm while sleeping.

  • Hot Water Bottles: Fill a hot water bottle and place it under your blankets for added warmth.


3. Close Off Unused Rooms

Focus on heating the areas you use most:

  • Close Doors: Shut doors to unused rooms to concentrate heat in living spaces.

  • Block Drafts: Use towels or draft stoppers to seal gaps under doors and windows.


4. Maximize Natural Heat

Take advantage of sunlight and insulation:

  • Open Curtains During the Day: Let sunlight naturally warm your home.

  • Close Curtains at Night: Use heavy curtains or blankets to trap heat inside.


5. Use Alternative Heat Sources

If you have other heat sources, use them wisely:

  • Fireplace: If you have a working fireplace, use it to provide additional warmth.

  • Oven: Avoid using your oven as a heat source, as it can be a fire hazard.


6. Stay Hydrated and Warm from the Inside

Warm beverages and meals can help maintain body heat:

  • Hot Drinks: Sip on tea, coffee, or hot chocolate.

  • Soups and Stews: Enjoy warm, hearty meals to keep your body temperature up.


7. Seal Windows and Doors

Prevent cold air from entering your home:

  • Weather Stripping: Apply temporary weather stripping to drafty windows and doors.

  • Plastic Film Kits: Use window insulation kits to create an extra barrier against the cold.


8. Check Carbon Monoxide Detectors

If you’re using alternative heat sources, safety is critical:

  • Test Detectors: Ensure your carbon monoxide detectors are functioning properly.

  • Ventilation: Never use fuel-burning devices (e.g., generators or grills) indoors.


9. Stay Active

Physical activity can help generate body heat:

  • Light Exercise: Do light stretches or household chores to keep your blood flowing.

  • Warm-Up Breaks: Take short breaks to move around if you’ve been sitting for a while.


10. Call a Professional ASAP

While these tips can help in the short term, it’s important to get your furnace repaired as soon as possible. Contact a licensed HVAC technician to diagnose and fix the issue.
