When winter storms knock out your power, staying warm isn’t just about comfort—it’s about safety. If your heat suddenly shuts off in freezing weather, your home can lose warmth faster than you expect. The good news? With a little preparation and the right strategies, you can protect both your space and the people inside it.
Here are four practical, reliable ways to keep your house warmer during a cold-weather blackout.
1. Pre-Heat Your Home Before the Storm Hits
If a winter storm is in the forecast, take action early. Turning your thermostat up a few degrees before the power goes out helps your home hold onto heat longer once everything shuts down.
To maximize that warmth:
-
Seal drafts with door stoppers or rolled towels
-
Hang thermal curtains or blankets over windows
-
Use plastic window insulation kits if you have them
Think of this as charging your home’s “heat battery.” The warmer it starts, the more time you’ll have before temperatures become uncomfortable—or unsafe.
2. Live Small: Gather Everyone in One Warm Room
Trying to heat an entire house without power is a losing battle. Instead, pick one room and make it your warm zone.
Choose wisely:
-
Upper-floor rooms stay warmer since heat rises
-
Rooms with sunlight can gain extra warmth during the day
-
Smaller rooms are easier to heat and insulate
Once chosen, keep doors closed, block drafts, and cover windows. If you have an indoor-safe heater, this is the best place to use it. For extra insulation, an indoor tent can help trap body heat and create a surprisingly cozy microclimate.
3. Use a DIY Candle-and-Clay-Pot Heater (Carefully)
If you don’t have a portable heater, a candle-and-clay-pot heater can provide a small but meaningful boost in warmth—especially in tight spaces.
What you’ll need:
-
1–3 clay flower pots (different sizes work best)
-
Bricks or stone tiles (non-flammable base)
-
Several candles
How it works:
The candles heat the clay pots, which slowly radiate warmth instead of letting heat escape straight to the ceiling.
⚠️ Safety first:
-
Never leave candles unattended
-
Keep flammable items far away
-
Use this only in well-ventilated areas
This won’t replace a furnace, but in a cold emergency, every degree counts.
4. Keep Your Furnace Running With a Battery Backup
If your home uses a gas furnace, there’s good news: it still needs electricity to operate, but not much. A generator or high-capacity battery backup can keep it running during a blackout.
Installing a transfer switch allows you to safely power your furnace with an alternative source. While installation may require an electrician, this upgrade can be a game-changer during extended winter outages—providing real heat when you need it most.
Stay Calm, Stay Warm, Stay Prepared
Losing heat during winter is stressful, but preparation makes all the difference. Whether it’s sealing drafts, choosing the right room, or investing in backup power, these steps can help you ride out a blackout safely and comfortably.
Winter storms are unpredictable—but your response doesn’t have to be. A warm home starts with smart planning.
