Abstract: An infrared, room heater system for installation in a wall or on a floor. An electric fan assembly draws room air into a housing, then through three parallel, air transit channels where the air is heated by infrared radiation within and about a heat exchanger assembly, and then back out into the room. One or more ceramic heating elements attached to a first copper plate emit infrared radiation when electrically energized. The first copper plate lies adjacent to, but spaced away from, a second copper plate such that radiation emitted from the heating elements reflects back and forth between the plates. Room air passed between the copper plates is heated by heat radiation concentrated between the plates, thereby achieving both energy and space efficiency.

Abstract: The inventive warmer apparatus comprises a holding unit, enclosed on four sides, but open at the top to allow restaurants and kitchen operators easy access to food held in it. Food in the apparatus is exposed to radiant heat generated by a heated bottom surface and to hot convection air. Part of the convection air is used to create an air curtain to improve heat loss characteristics and protect from the environment. The apparatus uses a combination of radiant heat, convection air and a warm air curtain to keep food products hot and crisp. The air curtain provides additional food protection. The warmer apparatus conditions food to attain a noncooking biologically safe temperature and to retain its freshly cooked texture and internal moisture for at least twenty minutes. This allows restaurants to serve such food items longer to its customers, allowing more efficient batch cooking and significantly reducing food waste.
