As winter settles in and temperatures drop, households across the country turn to supplemental space heaters to warm drafty rooms and cold corners. These compact devices provide quick, comforting heat, but beneath their convenience lies a serious hazard that firefighters urgently want the public to understand.

A widespread misconception is that any outlet or power strip can safely handle any device. Fire departments nationwide warn this is dangerously false. As heating season peaks, they emphasize one rule above all: never plug a space heater into a power strip or surge protector.

This warning went viral after Umatilla County Fire District #1 in Oregon shared photos of a melted power strip destroyed by a heater’s electrical load. Power strips are designed for low-voltage electronics, not high-wattage appliances. Space heaters draw massive current to generate heat, overwhelming power strips that were never engineered for such demand.

When overloaded, these strips overheat internally, melting plastic and wiring until they ignite. Firefighters say this failure can happen silently and quickly. The danger is not hypothetical; in Ohio, a space-heater-related fire recently destroyed a home after a power strip overheated and ignited nearby furniture.

Because heaters can reach internal temperatures of 600°F, they must be plugged directly into a wall outlet, which uses heavier-gauge wiring capable of handling the load. Fire officials also stress maintaining a three-foot safety zone around heaters—keeping them far from bedding, curtains, furniture, and other combustibles.

Placement matters as well. Heaters should sit on a flat, hard surface, never on carpet or elevated spots where they can tip over. Even with modern safety features, firefighters insist heaters should never run unattended or while anyone is asleep.

These warnings connect to broader electrical safety concerns. Extension cords should not be used as permanent wiring, and heat-producing appliances should always be unplugged when not in use. As winter deepens, a few simple precautions can prevent devastating fires. Stay warm—and stay safe.
