What is an oil filled radiator and how does it work?
An oil filled radiator is a type of electric heater that uses a thermally conductive oil to retain heat. It consists of a metal casing filled with oil and a heating element, usually an electric coil. When the heater is turned on, the coil heats the oil, which then transfers the heat to the metal casing. The casing is designed with fins or columns to increase the surface area, allowing the heat to be released into the room more efficiently.
The oil filled radiator works by using the principle of convection to circulate warm air around the room. As the oil is heated, it expands and rises, creating a circulation of warm air that is then cooled as it comes into contact with the surroundings. This circulation of air creates a consistent and comfortable temperature in the room. Oil filled radiators are often preferred over other types of electric heaters because they are relatively safe, energy-efficient, and provide a gentle, consistent heat. They are also often more cost-effective than other types of heaters, especially when used to heat a single room or area.
