A wall mounted electric heating device for warming or drying a person standing in front thereof by directing a stream of air on the person includes an elongated vertically upstanding housing adapted to be mounted on a wall and having an upper blower portion housing a blower for generating a downward flow of air over a thermostatically protected electric resistance heating element into an elongated, closed-bottom vent portion having a front wall provided with an elongated, narrow, rectangular front vent opening which has a length corresponding approximately to the height of a person standing in front of the device. The vent portion is defined by flat front, side and rear walls which continuously converge symmetrically with respect to each other to form a downwardly converging air flow conduit having a rectangular cross-section which decreases continuously along the length of the vent portion to its bottom thereof to ensure uniform airflow outwardly along the entire length of the front vent opening. The energization of the heating element is controlled by a timer and an airflow responsive switch allows energization of the heating element only if the blower is operative. A curved air deflector is provided in the upper part of the vent portion to ensure sufficient air flow through the upper portion of the vent opening.
