To stay safe, always plug space heaters directly into a wall outlet—never into a strip or extension cord. Keep a three-foot clearance around the heater, free of flammable items like curtains or bedding. Only use the heater while you’re present, never while sleeping or out of the house. Always place it on a stable, non-flammable surface.
Lastly, inspect your heater regularly for damage, use models certified by trusted safety organizations, and follow all manufacturer instructions. With careful use, space heaters can be both effective and safe—just avoid shortcuts that could cost your home or your life.
