As temperatures drop and winter settles in, many homeowners turn to space heaters for quick, convenient warmth. These portable heaters can make a room cozy in minutes—but they’re also one of the most common causes of winter house fires. At PuroClean of Hoboken, we respond to countless fire and smoke emergencies every year, and a surprising amount of them start with a simple space heater being used the wrong way.

Most people think they know how to operate a space heater safely—but the truth is, many common habits create hidden risks. Here’s what homeowners often get wrong, and how to use your heater safely this winter.
1. Putting Space Heaters Too Close to Everyday Items
One of the biggest mistakes people make is placing a space heater too close to things that can burn. Blankets, clothing, curtains, furniture, and even holiday décor can ignite quickly when exposed to high heat.
The rule:
Keep at least three feet of clearance around all sides of the heater.
If it can burn, it needs distance.
2. Plugging a Space Heater Into the Wrong Outlet
Many people don’t realize that space heaters draw a lot of power—more than most small appliances. Plugging one into a power strip, extension cord, or overloaded outlet can cause the cord to melt or spark a fire inside the wall.
The rule:
Always plug your space heater directly into a wall outlet.
Avoid sharing the outlet with other high-demand devices like microwaves or vacuums.
3. Leaving a Space Heater Running Unattended
It’s tempting to leave a space heater on “just for a minute” while you step into another room. But most heater-related fires happen when no one is watching.
The rule:
Turn your heater off when you leave the room or go to sleep.
If you wouldn’t leave a stove unattended, don’t leave a heater either.
4. Using Old or Damaged Heaters
A lot of families keep old space heaters in basements or closets, pulling them out every winter without checking their condition. Older models may lack modern safety features like tip-over shutoff or overheat protection. Frayed cords or loose plugs are especially dangerous.
The rule:
Inspect your space heater before each use. If it’s more than 8–10 years old, consider replacing it with a safer, modern unit.
5. Running a Heater Near Water
People sometimes use space heaters in bathrooms or kitchens to warm cold tile floors. But electricity and water are a dangerous combination. A heater placed too close to a tub, sink, or wet floor can cause electrical shock or start a fire.
The rule:
Avoid using space heaters in wet or damp areas.
If you must heat a bathroom, only use a heater specifically listed for bathroom use.
6. Using Space Heaters as a Primary Heat Source
Space heaters are designed for temporary, supplemental heat—not as the main heating system. Running one all day puts stress on electrical circuits, increases fire risk, and can leave parts of your home unevenly heated.
The rule:
Use space heaters sparingly. If your home feels constantly cold, have your main heating system inspected instead.
