Space heaters can make the chilly corners of your home much more comfortable. However, this convenient technology also comes with safety risks if not used properly.
From fire hazards to electrical malfunctions, it’s essential to take precautions when using electric space heaters. These compact devices can effectively warm up chilly spaces, but improper use can turn them into serious safety risks.
Here’s what you need to know to stay warm and safe this winter.
Outlet Safety: Plugging In Space Heaters
Space heaters require significant electrical power to operate safely. Loose outlets or overloaded circuits can lead to overheating, sparks, or even electrical fires.
Let’s break down some key precautions to keep in mind:
- If an outlet feels “loose” in any way, do not use that outlet for a space heater.
- If the space heater plug feels loose in the outlet or has trouble staying firmly in the outlet, don’t use that outlet. However, if this happens in all outlets for a given device, it is the device cord; avoid using it.
- Don’t use more than one heating device in a single outlet, and avoid using more than one heating device on a single circuit. If you have more than one outlet along a wall or in a room, they very well could be on the same circuit, depending on the age of your home.
Turning On: Using Space Heaters Safely
Proper placement, regular maintenance, and safe operating practices are essential for reducing risks like fire, electrical malfunctions, and overheating in space heaters.
- Keep space heaters level and at least 3 feet from any fabric (curtains, couch, carpet, etc.)
- Ensure the device is clean and free of dirt, dust, and debris.
- If a space heater appears to operate erratically in any way, do not use it.
- Never leave a space heater running for long periods of time, and especially not overnight; it is best to use them intermittently; depending on your situation, a suggested practice would be to turn it off/unplug it for 10 minutes every hour if you depend on its use for longer periods.
- Replace old devices at least every ten years.
- Don’t leave space heaters on unattended.
Importantly: Avoid Using Extension Cords, Power Strips, or Outlet Extenders
Space heaters and other heating devices draw a significant amount of power, making them incompatible with most extension cords, power strips, or outlet extenders. These devices are designed to be plugged directly into a wall outlet to prevent overheating and reduce the risk of electrical fires. Using improper connections can overload the wiring, create dangerous heat buildup, and compromise the safety of your home.
A note on outlet extenders: although convenient, they can be even less safe than a power strip as they cover the outlet and essentially hide it from view, and can sag out of the outlet due to the weight of cords plugged into it. Sagging can lead to poor electrical connections and overheating. Be sure to check these periodically for fit into the outlet, and for the fit of cords plugged into it. Also, unplug outlet extenders periodically to inspect the wall outlet to ensure there are no signs of electrical issues (charring or melting).
One final but significant reminder…
Smoke Detectors: fires can occur with or without electricity, especially when you focus on keeping your family warm and healthy during extreme conditions.

We are super passionate about helping to protect our customers. If you have questions, especially if you suspect an electrical risk in your home, please contact us immediately. Ting (the sensor and service) is statistically proven to prevent ~80% of electrical fires, significantly reducing electrical fire risk in homes. Ting alone cannot eliminate 100% of electrical fire risks. Trust your senses. Flickering lights, intermittent lights or devices, frequently tripping breakers, or electrical odors can indicate that an electrical hazard is developing.
