How to Heat Your Home Without Electricity

One of the first steps in keeping your home warm without electricity is to improve insulation. Many homes across St. Louis, especially older properties, have drafty windows and doors that allow cold air to sneak in, even during short power outages. These homes can benefit from quick insulation fixes.

To reduce heat loss, use weatherstrips to seal noticeable gaps around windows and doors. You can also place blankets or towels along windows or use doorstoppers to keep your house warm if you don’t have weatherstripping materials on hand.

If you’re comfortable spending time in one main space while you wait for the power to return, closing off doors to unused rooms can make a difference in temperature. Limiting airflow to less-used areas helps create a natural heat barrier, allowing warmth to stay concentrated where you need it the most.

If possible, choose a room or area in your home that doesn’t connect directly to exterior walls, which tend to lose heat more quickly in cold weather. Warm up with blankets, a sleeping bag, and hand warmers to create an insulated environment and retain body heat until power returns.

If you’re not comfortable using a fuel-based heater, you can try a DIY alternative. Candle heaters, for example, can help maintain heat in a small area. While they might not generate as much heat as other options, they are typically safe and easy to try.

To make a candle heater, place tea candles on a fire-safe base, such as bricks or a metal tray. Set upside-down clay pots over the candles, elevated slightly to allow airflow. Light the candles and wait for a small heat source to develop. As a safety precaution, monitor the candles and blow them out if the pots become too warm. Note: candles should never be used as a primary heat source.

Generators can provide a lot of heat by powering electricity to your furnace, heat pump, or even space heaters during a power outage. They’re great for extreme cold, or for long-term power outages during severe weather, as they can help prevent water pipes from freezing and bursting while keeping your indoor warm.

If you use a generator to heat your living space, be sure to monitor it regularly. While generators serve as a generally reliable backup heating solution, they require close monitoring to avoid overheating or breaking.

St. Louis often experiences sudden temperature drops during winter, especially after mild weather days. During power outages, interior walls and basements may feel extra cold due to moisture buildup and concrete surfaces, which can absorb it.

To counter the cold, close basement doors, block off drafty stairways with sheets or blankets, and stay in a room away from exterior brick walls. If you’re expecting inclement weather, such as heavy snow, sleet, or rain, check your home’s exterior for any noticeable openings where cold air or moisture could enter. These spaces might show up around older bricks, doorways, windows, or around your home’s foundation.
