Space Heater Safety: Warmth Without the Worry
Space heaters can be a wonderfully frugal and convenient way to heat a small space. They’re also one of the leading causes of home fires when used carelessly. Fire doesn’t care if you were “just gone for a minute.” A space heater demands respect, attention, and a little common sense.
Start with distance. Anything that can burn—clothes, blankets, furniture, curtains—needs at least three feet of space between it and the heater. Crowding a heater is how cozy turns catastrophic.
Never leave a space heater unattended. Not while you’re running errands, not while you’re sleeping. If you’re not actively monitoring it, turn it off. Fires don’t announce themselves politely; they arrive loud and fast.
Plug space heaters directly into the wall. Always. Extension cords and power strips aren’t built to handle the heavy electrical load and can overheat quickly. That heat doesn’t stay contained—it spreads.
Placement matters. Heaters should sit on flat, level surfaces on the ground. No tables, no beds, no balancing acts. A tipped heater is a hazard unless it has an automatic shut-off feature, which is a must-have.
Before each use, check the cord. If it’s cracked, frayed, or damaged in any way, the heater is done. Retire it. Using damaged electrical equipment is gambling with fire.
Keep kids well away from space heaters. Curious hands and high heat are a dangerous combination. And never touch an electric heater if you’re wet—water and electricity have never been friends.
