In a heating device in which a loop-type heat pipe is disposed in which a working fluid for transmitting exhaust heat to the air is carried by an evaporator provided in a passage, and a condensing part of the heat pipe is attached to an air outlet side of a heater core for a vehicle interior. A liquid tank is disposed in a second pipe of the heat pipe that communicates the downstream of the condensing section with the lower part of the evaporator, and the communication pipe having an opening near the bottom of the liquid tank is connected to the vacuum tank. first and second valve means are interposed in the second pipe and the communication pipe, respectively, and when the heating device is turned off, the first valve means is closed and the second valve means is opened, so that the inside of the liquid tank and the evaporator is The hydraulic fluid in the vacuum tank is sucked into the vacuum tank, and after a certain period of time has elapsed since the heating device is turned off, the first and second valve means are both opened to return the hydraulic fluid in the vacuum tank to the liquid tank and the evaporator. and a control means configured to close the second valve means and open the first valve means to operate the heating system and store negative pressure in the vacuum tank when the heating device is turned on. A vehicle heating system featuring:
