Abstract: A heater having a heat exchanger with a heat emission device disposed therein. The heater includes an airflow channel formed by a shell disposed about the heat exchanger. The heat emission device is physically coupled to the shell by a coupling device that is consisting essentially of a non-metal heat insulating interface structure. The heater includes a housing disposed about the shell. The heat emission device is not directly physically coupled to the airflow channel by a metal structure. The heat emission device is not directly physically coupled to the housing by a metal structure. The interface structure is a collar disposed about an end of the heat emission device and through an aperture of a side wall of the shell. The interface structure is ceramic.

Abstract: A heater comprising a housing including an intake aperture and an output aperture. The heater includes a heat exchanger operatively disposed within the housing between the intake aperture and the output aperture. The heat exchanger includes a shell forming a cavity therein, wherein an interior surface of the shell is substantially black in the infrared domain. The heater includes an infrared emission module disposed within the cavity of the heat exchanger and substantially enclosed thereby such that emitted infrared light does not escape therefrom. The infrared emission module includes a first infrared emitter and a second infrared emitter. The heater includes a fan positioned to motivate air into the housing through the intake aperture, across the heat exchanger, and out of the output aperture. The heater also includes a power module functionally coupled to the infrared emission module and the fan and configured to provide operational power thereto.
