What Space Heaters Can I Leave On Overnight?

When it comes to space heater safety, it is generally recommended not to leave on heaters for long periods, especially when not supervised. However, some heaters like oil-filled, electric ceramic and infrared space heaters are the safest overnight heating and comfortability options.

  • To begin, double-check that your space heater is in good working order. Take note of any dings, dents, or other flaws in your electrical cords. Depending on the type of space heater, they may result in an electric shock, a fire, or a carbon monoxide gas leak.
  • Avoid putting combustible materials near space heaters. Keep a 3-foot radius around your space heater or more. Stacks of papers, plants, blankets, and bedding should be out of the unit’s range.
  • Keep space heaters away from the bedside. Place a space heater away from your bed, no matter how much you want to curl up in the warmth.
  • Purchase space heaters that have both overheat and tip-over protection. These safety features should help alleviate some of the anxiety associated with using a space heater.

    A tip-over or tilt-over switch ensures that the unit shuts off automatically if it is tipped over. Overheat protection detects and shuts off the unit when the temperature reaches dangerous levels.
  • Connect your space heater to the outlet directly. When dealing with an electric heater, using an extension cord is not recommended.

    The extension’s chances of overheating, causing electrical shock injuries, or causing fires are high and should be avoided. If you need to use an extension cord, make sure it’s graded and sized correctly for your space heater.
  • Smoke and carbon monoxide detectors should be installed on every level of your house. To avoid carbon monoxide poisoning, place these alarms outside of sleeping areas and inside each bedroom. Check to see if they’re in good working order regularly.

We have done an extensive amount of research to ensure you are getting the best of the best. It is also important to note that we have not put these heaters in any particular order.

So without further ado, the following heaters are safe to run overnight, provided you follow the safety tips listed above.
