The primary function of radiators is to disperse steam heat that is generated by boilers. The dispersed steam heats up the room. Radiators are made of cast iron, which is prone to rust. The rust can cause the paint to flake, requiring repainting of the radiator. Before repainting, you must first remove the layers of paint from the radiator.
