You should not leave most portable electric heaters on all night while you sleep unless it is specifically designed and safety-certified for overnight use, such as an oil-filled radiator with tip-over protection and an automatic shut-off. While modern electric heaters from reputable brands like Stiebel Eltron, DeLonghi, or Dyson have extensive safety features, leaving any high-wattage heating element unattended for 8 hours introduces risks of fire, overheating, dry air, and carbon monoxide issues if it is a faulty unit. Portable fan heaters and infrared heaters can overheat if covered by blankets, clothing, or dust, and their heating elements can ignite nearby curtains or furniture. If you must heat a bedroom overnight, the safest approach is to use a permanently installed wall-mounted panel heater or storage heater with a thermostat, timer, and overheat protection, keep it at least three feet from anything flammable, never use an extension cord, and ensure your smoke detector works. A better alternative for overnight is to heat the room before bed, then turn the heater off and use extra blankets, or use a low-wattage oil-filled radiator on a thermostat set to 60 to 65 degrees Fahrenheit to maintain safe background warmth.
