It is advisable to purchase a newer, electric heater that has been evaluated in a known testing facility, such as Underwriters Laboratory or Intertek, for safety. Using any type of space heater entails some risk, but many have key features that help minimize potential hazards.
Avoid indoor use of any space heater that uses open flame. Look for an electric heater with the ability to turn off automatically if it overheats, falls over or its grille is touched. A heater featuring a fan is best for disseminating heat throughout a room, and a heat-resistant handle is helpful for safe transport. General precautions, such as avoiding placement near flammables or in damp areas and avoiding use with an extension cord, apply when using any space heater.
