As temperatures drop, space heaters become a quick and effective way to warm up cold rooms. They’re especially helpful in homes with uneven heating or drafty spots. But fire departments consistently warn that these devices, while convenient, can become dangerous if not used properly.
The most important rule is simple: never plug a space heater into a power strip or surge protector. These strips are designed for low-power electronics—not high-wattage appliances. A heater can draw enough electricity to overheat the strip, sometimes within minutes, leading to melting, sparks, or fire. The safest option is to plug the heater directly into a wall outlet.
Placement also matters. Keep your heater at least three feet away from anything flammable—like curtains, bedding, or furniture. Always place it on a flat, stable surface to prevent tipping. And while it may be tempting to leave it running overnight, it’s best not to use space heaters while sleeping or unattended, since fires can spread quickly without warning.
Finally, follow general electrical safety habits. Unplug heaters when they’re not in use, and avoid using extension cords as a long-term solution. Taking a few simple precautions can make a big difference—helping you stay warm without putting your home at risk.
