ABSTRACT:
A portable room heater is provided comprising an upright enclosure defining an inlet at a lower end of the enclosure, an outlet at an upper end of the enclosure, and a passageway fluidly connecting the inlet and the outlet. The portable room heater further comprises a blower imparting an airflow through the passageway, and thereby creating an inlet airflow through the inlet and a noncoplanar outlet airflow through the outlet. A heat generating member in the passageway selectively heats air flowing through the passageway. A method is provided for warming a room comprising providing the portable electric heater, drawing air from a relatively lower horizontal plane of the room into the heater, heating the drawn air, and releasing the heated air in a substantially horizontal direction in a relatively higher horizontal plane of the room.
