OILHEATER
Oil heater
An oil heater, also known as an oil-filled heater, oil-filled radiator, or column heater, is a common form of convection heater used in domestic heating. Although filled with oil, it is electrically heated and does not involve burning any oil fuel, such as kerosene – the oil is used as a heat reservoir, not as a fuel.The above text is a snippet from Wikipedia: Oil heater
