An electric heating device for emitting a heated air flow, in particular for a sanitary room or washroom in a rail-borne vehicle, includes an air duct, a fan generating the air flow, a heating element heating the air flow and a first over-temperature switch. The first over-temperature switch can reversibly switch off the heating element when a first over-temperature is exceeded. A second over-temperature switch can irreversibly switch off the heating element when a second over-temperature is exceeded. The second over-temperature switch is disposed in a recess, depression or opening formed in the air duct. The second over-temperature switch has a disconnect or isolating switch to be thermally triggered for switching off the heating element. The thermally triggered disconnect or isolating switch can be triggered by a glass sphere or bead that breaks when the second over-temperature is exceeded.
