A flat plate surface heating unit with a glass-ceramic utensil-supporting cover plate and a metal-sheathed heating element in direct contact with the underside of the cover plate. The heating element is supported on an open framework of low thermal mass. An insulated reflector pan with a top reflective layer forms a closed housing around the heating element. The sheath is coated with a diffusion barrier of molecular film thickness, and the underside of the sheath is coated with a low emissivity coating.
