Kerosene heaters do not use electricity to generate heat. They are primarily fueled by kerosene, which is burned in a combustion chamber to produce heat. The heat generated is then radiated into the room or distributed through a fan, depending on the type of kerosene heater.
However, some kerosene heaters may have electrical components for features such as ignition, a fan to help distribute heat more evenly, or safety mechanisms like tip-over switches or overheating sensors. These electrical components typically consume a small amount of electricity, but their power usage is relatively low compared to other electric heating appliances.
The primary energy source for a kerosene heater is the kerosene fuel itself, and the electricity usage is generally minimal in comparison. Keep in mind that the main operating cost for a kerosene heater is the cost of the kerosene fuel itself, not the electricity required for its auxiliary components.
