When this type of heater draws electricity, it draws a ton of electric power. A heater that is filled with oil can be heated through convection. Convection heats the oil. Afterwards, this oil warms the area. It can be used to heat all of the room when it’s turned on. It only draws the current it will require to heat the room. How much power does it use?
