A winter grid-down event is one of the few emergencies that can hurt you inside your own home. The good news: staying warm and cooking without power is simple and cheap — as long as you respect the one rule that matters. Here's the gear we recommend, and the safety that keeps it from killing you.
Read this first: carbon monoxide kills silently
Every fuel-burning heater or stove produces carbon monoxide — an invisible, odorless gas that can kill in minutes. Follow these rules without exception:
- Only run heaters explicitly rated for indoor use, with a low-oxygen shutoff (ODS) and tip-over protection.
- Never use an outdoor propane heater, a charcoal or gas grill, a camp stove, or a generator inside a home, garage, tent, or camper — not even with a door open.
- Crack a window for fresh air even with an indoor-rated unit.
- Put a battery-powered carbon-monoxide alarm on every sleeping level, and test it.
Quick comparison
| Item | Job | Where to use | Notes |
|---|---|---|---|
| Indoor propane heater Best heat | Warm one room | Indoors (ventilated, indoor-rated) | Look for ODS + tip-over shutoff |
| Fire Disc / solid fuel | Off-grid cooking | Outdoors / well-ventilated | Long-storing, no moving parts |
| Waterproof matches | Reliable ignition | Anywhere | Backup to a lighter — "two is one" |
| CO alarm Non-negotiable | Detect carbon monoxide | Every sleeping level | Battery/battery-backup, UL-listed |
Our top picks
Mr. Heater Buddy (indoor-safe propane)
The default emergency heater for a reason: a compact radiant propane heater rated for indoor use, with an automatic low-oxygen shutoff and tip-over protection built in. Run it off one-pound cylinders or a refillable tank with a hose, and it will take the edge off a single room — the right strategy in a grid-down cold snap is to heat one room, not the whole house. Pair it with a carbon-monoxide alarm and a cracked window, always.
Pros
- Indoor-rated with low-oxygen + tip-over shutoff
- Runs on cheap, storable propane
- Enough radiant heat for one room
Cons
- Still requires ventilation and a CO alarm
- Cylinders don't last long at high output
Fuel tip: disposable one-pound cylinders pile up fast. Two ways to run off a standard 20 lb tank instead: a Buddy-series hose connects the heater straight to the big tank (Mr. Heater recommends adding a fuel filter to keep the regulator clear), or a set of refillable 1 lb cylinders plus a refill adapter lets you top up your own for portability. Use only DOT-approved refillable cylinders, keep the tank outside the sealed room, refill outdoors away from ignition sources, and never overfill.

When the power's out, you still need to boil water and heat food. A solid-fuel disc is about as foolproof as off-grid cooking gets: light it, set your pot on a stand above it, and it burns steadily with nothing to pump, prime, or break. It stores for years and shrugs off wind and damp better than loose tinder. Use it outdoors or in a well-ventilated space — like any combustion, it produces carbon monoxide indoors.
Pros
- Dead-simple, nothing to break
- Long shelf life; compact to store
- Works in wind and damp conditions
Cons
- Outdoor / ventilated use only
- Slower than a dialed-in gas burner
Waterproof Matches
Heat and cooking fuel are useless if you can't light them. Waterproof, windproof matches are the cheap backup to your primary lighter — the "two is one, one is none" rule applied to fire. Stash a box with your heater, another with your cooking kit, and a third in your bug-out bag.
Pros
- Light in wind and wet where a lighter fails
- Cheap enough to stage everywhere
- No fuel to evaporate or valve to fail
Cons
- Finite — pack more than you think you need
- Keep the striker dry too
Battery-Backup Carbon Monoxide Alarm
This is the one item on the page that isn't optional. Every fuel-burning heater or stove produces carbon monoxide — invisible, odorless, and capable of killing a sleeping family — and a grid-down heating setup is exactly when you're most likely to be burning fuel indoors. A battery-powered or battery-backup CO alarm keeps working when the power doesn't. Put one on every sleeping level, buy a UL-listed unit from a name you recognize (First Alert, Kidde), and test it when you stage your winter gear.
Pros
- Works with the power out (battery / backup)
- The only thing that catches CO before you do
- Cheap next to what it protects
Cons
- Sensors expire — replace per the label
- Insist on UL-listed; skip no-name units
Staying warm when the heat goes out
- Heat one room, not the house. Pick the smallest room that fits everyone, close it off, and concentrate your heat and bodies there. It's the difference between comfortable and out of fuel by morning.
- Layer passive warmth first. Wool blankets, sleeping bags rated for the cold, hats, and closed curtains keep heat in before you burn any fuel. A heater is a supplement to insulation, not a substitute.
- Store fuel safely. Keep propane and other fuels outdoors or in a detached, ventilated space — never in a living area. See our fuel storage guide for quantities and rotation.
- Have two ways to cook and two ways to light them. A stove plus a solid-fuel option; a lighter plus waterproof matches.
- A power station covers electric warmth for the vulnerable. For infants, the elderly, or medical needs, a solar generator running a small electric heater avoids combustion entirely — as long as its output can handle the load.
