Why do heating coils of a room heater have a shiny cuvered metal surface?

The shiny covered metal surface of heating coils in a room heater is typically made of materials like aluminum or stainless steel, which enhance durability and efficiency. This reflective surface helps to maximize heat radiation and minimize heat loss by directing warmth into the room. Additionally, the shiny coating can improve aesthetic appeal and provide some level of protection against corrosion and oxidation.
