Abstract
A baseboard heater for mounting against a wall and spaced from the floor comprises a casing having an open bottom and upper front side which permits the free upward and then forward free flow of air therethrough. An elongated electrical heating element mounted therein adjacent the open bottom thereof is provided with a high temperature cut-off switch. A switch actuator including a sensing tube coextending alongside the heating element is cooled by incoming air to preclude switch actuation but is quickly heated by the heating element to effect cut-off when airflow is blocked.
