Abstract
A method and apparatus for heating by use of tungsten-halogen heating elements. A space heater for use with a radiator or other heat using apparatus employs the principle of collecting heat emitted by a tungsten-halogen element by use of a heat transfer fluid, be it gaseous, liquid or liquid-emulating solids, and transferring the heat therefrom to a reservoir, other storage means or radiator. A specially devised "pancake element" is employed in the preferred embodiment so as to provide a maximum surface area for the radiation and subsequent transfer of heat, which emanates from the element, to a transfer fluid. With the exception of the disc-shaped outer envelope, the heating element of the instant invention resembles the conventional tungsten-halogen lamp. Adjunct DC power generation is acquired through use of photovoltaic cellular arrays.
