Space Heater Safety Features
Certification: Make sure the heater you buy carries a safety certification label from an independent testing organization, such as the UL mark, the ETL label from Intertek, or certification from CSA International.
Shutoff features: A smart sensor that automatically shuts off a heater when it overheats is a must. You’ll also want a tip-over switch that does the same if the heater is knocked over.
A ground-fault circuit interrupter (GFCI) plug: Most space heaters don’t come equipped with a GFCI plug, which prevents electric shock. Heaters without one should not be used around water, manufacturers advise.
A sturdy cord: Most space heaters come with a cord that’s 6 feet long. To prevent overheating, never use an extension cord or a power strip with an electric heater.
Safest Space Heaters From CR's Tests
In our most recent tests, 49 models got high marks for fire safety; very few, however, rated Good or better on our hot-surface test. The two space heaters below earn Excellent or Very Good ratings in both our fire safety and hot-surface tests, and also have tip-over switches that automatically shut the appliance off if it gets knocked over.
