Using a Gas Stove as a Heater Is Not Safe

Say your kitchen is 12 by 12 feet and the power is out. The burners still make heat, but that heat comes with exhaust gases, uncovered flame, and a design that expects you to stand nearby for minutes, not sit in the room for hours.

If your real goal is steady warmth, the safer path is a heater made for indoor space heating, plus a working carbon monoxide alarm on every level of the house.

Using a Gas Stove as a Heater

A kitchen gas stove should not be used as a room heater. No timer, range hood, or low flame makes hours of burner use safe, and the safe answer in 2026 is to turn the burner off and use an appliance listed for heating instead.

Say you light two burners during a power outage and leave them running overnight. The flames consume gas and oxygen while releasing carbon monoxide and water vapor into the room; a cooking range isn’t designed to vent those combustion products continuously into your living space. A hood that exhausts outdoors may remove some fumes, but it isn’t a substitute for the appliance’s required venting or for a carbon monoxide alarm.

The burner also adds an open flame where a heater’s controls and clearances would normally manage the heat. Nearby cabinets, curtains, paper, cookware handles, and the stove’s own surfaces can become dangerously hot, while a pot left dry can overheat. Keep the range for cooking, and use the manufacturer’s instructions for how long each burner may operate.

A gas stove’s thermostat doesn’t regulate room temperature because the burner controls cooking output, not space-heating demand. Turning the knob down may reduce gas use, but it doesn’t remove the combustion, fire, or ventilation problem. For background on the burner itself, see how gas stoves work.

When The Answer Changes

The answer changes only when you’re talking about a separate gas heater that is listed for indoor space heating, not a kitchen range. In 2026, an indoor-rated gas heater can be safe when its installation manual, ventilation requirements, fuel type, clearances, and local code all allow the installation.

A vent-free heater needs a built-in oxygen depletion sensor, and local authorities must allow that kind of appliance in your home. The sensor is designed to shut the gas off if oxygen falls too low; it isn’t permission to use any gas-burning appliance indoors or to skip a working CO alarm.

Outdoor patio heaters, propane appliances without an indoor rating, torpedo heaters, and construction heaters belong outside. Their combustion and exhaust arrangements assume open air; moving one into a garage, basement, or room can fill the space with carbon monoxide or create a fire hazard. A diesel heater is a different case only when it is designed to exhaust outside the cabin and installed as directed.

For a purpose-built indoor gas heater

ProCom Ventless Dual Fuel Gas Stove

Product 2 is an indoor-only, ventless dual-fuel heater with a built-in pilot oxygen depletion sensor and thermostat remote; consider it only after confirming that vent-free heating is allowed where you live and that the room meets the manual’s requirements.

Electric alternative

DREO Indoor Space Heater

Product 1 gives you thermostat-controlled electric heat instead of asking a cooking range to heat the house. Its 1,500-watt PTC system, tip-detection sensor and overheat protection address the main risks in this article, though you should still plug it directly into a wall outlet and keep clear space around it.

Code-dependent gas heat

ProCom Ventless Dual Fuel Stove

Product 2 is a purpose-built indoor heater, unlike a kitchen range, and can use natural gas or propane with remote temperature control. Its oxygen depletion sensor is designed to shut the heater down if carbon monoxide or low oxygen is detected, but you still need the required ventilation, a working CO alarm and local-code approval before using ventless gas heat.

What To Use Instead

The safest alternative to using a stove as a heater is a plug-in electric space heater for one room when the power is on. Choose a listed model with a thermostat, tip-over protection and overheat shutoff, then plug it straight into a wall outlet—never an extension cord or power strip.

Useful for one room

DREO Space Heater

Product 1 suits a bedroom or living room with power available because its 1,500 W PTC heater has a thermostat adjustable from 41–95°F, plus tilt detection and overheat protection.

Keep at least 3 feet of clearance from curtains, bedding, furniture and clothing. A 1,500 W heater draws about 12.5 amps on a standard 120 V circuit, so don’t share that outlet or circuit with another high-wattage appliance. Look for a UL, ETL or CSA listing, and follow the manual about sleeping or leaving the heater running.

For fuel heat, use only an indoor-rated gas heater, and only where local code allows it. A ventless model still needs the ventilation specified in its manual, a working CO alarm and the required clearance; an oxygen-depletion sensor is a useful safety feature, not permission to ignore the rules. Check how gas heaters work before choosing one for an outage, since electric heat won’t operate when the power is off.

What To Do Before You Light Anything

Gas stove safety starts with a short check: carbon monoxide from a gas stove can become an emergency, so stop before lighting anything if the appliance, room or symptoms give you a reason to doubt it.
