Can Space Heaters Cause Fires?

Yes, space heaters can cause fires, but most incidents are preventable with the right setup and habits. Misuse, damaged components, and poor placement are the most common factors.

At BCC Restoration, we are IICRC-certified fire damage restoration experts. We’ve come across many space heater incidents, and we want to share how to prevent and handle them.

Why Do Space Heaters Cause Fires?

• Electrical Overload and Overheating: Loose or worn outlets, improper adapters, or older two-prong receptacles increase resistance and heat.
• Proximity Ignition: Flammable items (blankets, curtains, furniture, holiday décor) within three feet can ignite from radiant heat.
• Mechanical and Safety Failures: Older units without tip-over/overheat shutoff, broken thermostats, or damaged cords/plug blades can spark a fire.
• Environmental and Usage Factors: High dust buildup on heating elements can smolder. Damp environments (common in the PNW) raise corrosion and short-circuit risk. Pets or kids tipping units; running heaters unattended or while sleeping.

Can a plug-in heater cause a fire? 

Yes, if plugged into power strips, long extension cords, or worn outlets. Electric models are usually safer than fuel-burning ones. However, they can catch fire or overheat wiring if not used properly.

Warning Signs Your Heater Setup Isn’t Safe

• Outlet, cord, or plug is warm to the touch, discolored, or smells like hot plastic.
• Lights flicker or breakers trip when the heater runs.
• The heater cycles constantly, rattles, or has a frayed cord.
• You see scorch marks around the outlet or on the plug.

How to Prevent Home Fires Caused by Space Heaters

The key to safe space heater use begins with placement. Place your heater on a flat, safe surface. Keep it at least three feet away from anything that can catch fire, like curtains, bedding, furniture, and clothes.

Never leave a space heater on when you’re not around or while you sleep. Always plug it directly into a wall outlet. Avoid using extension cords or power strips, as they can overheat and cause fires.

If a Space Heater Fire or Smoke Incident Occurs: What to Do 

1. Call 911, evacuate, and do not re-enter until cleared.
2. If safe and advised, shut off power to the affected circuit.
3. Avoid DIY cleanup, as soot and residues can spread and set stains.
4. Call BCC Restoration anytime, 24/7. We’ll perform emergency board-up, water extraction (from sprinklers/hoses), and secure the site.
5. Document damage and keep receipts for your insurer.

When to Call an Electrician vs. BCC Restoration

Call an electrician if outlets run hot, breakers trip, or wiring appears damaged. If you see flickering lights while using your space heater, trip circuit breakers often, or smell burning from outlets, these are signs of electrical problems. You should contact a licensed electrician right away. These problems show possible wiring issues or overloaded circuits. If ignored, they could cause fires.
