What material stores heat in storage heaters?

What material stores heat in storage heaters?

• A. Ceramic Tiles
• B. Fiberglass
• C. Steel Plates
• D. Fire clay blocks

Answer: (D)

Storage heaters rely on a material with high thermal mass that can soak up heat during charging and then release it slowly over time. Fire clay blocks fit this role well because they are dense ceramic blocks with a large heat capacity and good heat retention. They store a lot of heat when electricity is applied and then dissipate it gradually to keep the space warm, which is exactly what storage heaters are designed to do. Ceramic tiles don’t have the same heavy mass, so they store less heat. Fiberglass is an insulator, meant to reduce heat flow rather than store it. Steel plates can conduct heat quickly and might feel warm, but they don’t hold heat for long periods, so they don’t provide the slow, sustained release that storage heaters rely on.
