A burning smell from your Vornado space heater is usually caused by accumulated dust burning off the heating elements, but it could also indicate an electrical fault or restricted airflow.
A light burning smell at first heat is normal, but persistent odors signal trouble. Dirty filters or blocked vents can cause overheating and odor issues. Electrical or metallic smells require immediate shutdown and inspection.
Running a space heater overnight increases the risk of fire. If the unit is left unattended or placed too close to flammable materials, such as curtains or bedding, it can ignite and lead to a devastating fire.
An electrical fire or overheating wire typically smells like melting plastic, burnt rubber, or acrid chemicals. Often, it can also produce a sharp, fishy odor or a metallic smell caused by melting wire coatings, wire insulation, or circuit boards getting too hot.
