When the weather turns cold, many people reach for a portable electric space heater. Used carefully, a space heater can warm one room. Used carelessly, it can start a fire. This guide summarizes safety advice from the U.S. Consumer Product Safety Commission (CPSC), and lists popular, widely reviewed space heaters and room thermometers on Amazon. A product is not safe just because it is popular, so the safety tips matter more than the product pick.
1. Why Space Heater Safety Matters
The CPSC estimates that portable heaters, including electric space heaters, were involved in an average of 1,700 fires per year, resulting in an average of 70 deaths and 160 injuries annually from 2017 to 2019. A CPSC staff report also found that portable heaters can present a hyperthermia (overheating) hazard, particularly for children, people with disabilities and senior citizens, who may be more susceptible because of their limited ability to act or react to the elevated temperature. The CPSC says not to leave portable heaters running unattended in a confined space around infants or people with reduced physical, sensory or mental capabilities.
2. Safety Rules from the CPSC
- Keep it 3 feet away: place heaters at least three feet from drapes, furniture, bedding, papers and clothes.
- Plug directly into the wall: never into an extension cord or power strip, which can overload and cause a fire.
- Never leave it on while sleeping or when you leave the room.
- Stable, level surface: place it where it will not be knocked over. Never run the cord under rugs or carpeting.
- Check for heat: if the plug, outlet or faceplate is hot, stop using the heater and have an electrician check it. If the cord is hot, disconnect it and have the heater inspected.
- Inspect before use: do not use a heater you suspect is damaged. Check the heater, cord and plug.
- Keep away from water to prevent electric shock.
- Check for recalls at cpsc.gov or SaferProducts.gov.
3. What to Look for When Buying
- A safety certification mark from a nationally recognized testing laboratory. The CPSC says a certified heater will have a safety certification mark and the most up-to-date safety features.
- Automatic tip-over shut-off. The CPSC says an automatic cut-off device is now required to turn off electric or kerosene heaters if they tip over. It is still good to check the listing for tip-over and overheat protection.
- A guard around the heating element.
- A thermostat and, if you want, a timer, so it does not run all night. Do not run it while sleeping.
- Choose the right wattage. A common 1,500-watt heater is fine for one small room, but never power a heater with an extension cord or power strip.

4. Fuel-Burning Heat and Carbon Monoxide
The CPSC says to have a professional inspect all fuel-burning heating systems, including furnaces, boilers, fireplaces, wood stoves, water heaters, chimneys, flues and vents, each year. These systems can produce carbon monoxide (CO), an odorless, colorless, poisonous gas, if they are improperly installed, poorly maintained, have defective or blocked venting, or are misused. Never refuel a fuel-burning portable heater while it is running. Turn it off and let it cool first. Make sure you have working smoke and CO alarms, as covered in our guide to smoke and carbon monoxide alarms. For outages, see power outage preparedness for seniors.
5. Know Your Home’s Temperature
A simple digital room thermometer helps you notice a cold room, and it lets you set a heater thermostat sensibly instead of leaving it high. These are widely reviewed examples.
