7 Best Space Heaters (2025), Tested and Reviewed

Yes, but of course not.

Space heaters are safer than ever. Modern space heaters are highly regulated, especially with regard to exposed heating elements and automatic shut-off switches to prevent overheating. But all heating devices need caution, and so do all devices that draw a lot of power over long periods of time.

Most residential heating fires start with actual fires – esp In fireplaces and fuel burners. But space heaters were responsible for more than 1,000 fires in the U.S. each year from 2017 to 2019, according to the U.S. Fire Administration. Although it accounts for only 3 percent of heating fires overall, it causes more than 40 percent of fatalities, as portable heaters tend to be placed right where people are and thus have a greater chance of containing fires.

So treat your space heater with the caution and wild suspicion it deserves. Here are some pretty handy safety tips courtesy of the fine federal experts at the USFA and the Consumer Product Safety Commission.

Never leave a space heater unattended. “Unattended” includes sleeping! If you insist on using one in your bedroom at night, get a device with a scheduled shut-off and use it, so it won’t run all night while you sleep. (Or, we might suggest A wonderful down comforter Instead? So warm.)

Plug your heater directly into the outlet. This is a big one. Do not use extension cords or power strips with space heaters. Added cord length creates an electrical load and can cause shorts, overheating, and fires. if you necessary Use a longer cord, consult an expert to make sure you get the correct gauge and rating.

Do not plug other appliances into the same outlet or circuit as the space heater. The worst that can happen is that you trip the circuit breaker. But that’s not fun, either.

Place a space heater only on the floor, on a flat surface. There is no particular need to place a space heater on a table or chair that may be unstable. Heat rises and travels around the room by convection.

Keep your heater at least 3 feet away from flammable objects. This includes bedding, drapes, furniture, the dress you’re going to wear, stray socks or stockings, your food delivery bag, and that great book you’re reading.

Do not leave a portable heater running in a room with a child. or with a person who has mobility issues. The risk is not just fire but hyperthermia.

Keep the space heater away from water and even general darkness. Bathrooms are notoriously dangerous places for high-wattage electrical devices. But also: you know that damp basement? Is that kind of cold and sometimes has puddles? Not a good place for a space heater.

Read the manual. Manufacturers have all kinds of good advice.
