A heating device in which an evaporator installed in a passage transports steam generated from a medium by exhaust heat in the exhaust passage to a condenser via a loop heat pipe, and the condenser is attached to the air outlet side of a heater core for a vehicle interior. A vapor pressure detection sensor and a vapor temperature detection sensor are provided in a heat pipe communicating with the evaporator and the condenser, and when the vapor pressure detection sensor detects an abnormal decrease in vapor pressure or the vapor temperature detection sensor detects an abnormal decrease in vapor pressure. A heating device for a vehicle, characterized in that a closing means for closing the heat pipe is disposed in the heat pipe when it is detected that the steam temperature is abnormally low even when the temperature is constant.
