た事を特徴とする自動車用暖房装置。 An exhaust heat exchanger that exchanges heat between the exhaust gas from the engine and engine cooling water to produce hot water, a heater core that exchanges heat between hot water and air to create warm air for heating, and multiple units that connect these devices. In an automobile heating system comprising a cooling water passage, a first cooling water passage connects an engine water jacket and an exhaust heat exchanger, and a second cooling water passage connects the exhaust heat exchanger and the heater. Each of the cooling water passages is provided with a three-way valve that changes the flow path based on a signal from a water temperature sensor that detects the temperature of the cooling water, and the remaining ends of the three-way valve are connected to each other by a first bypass pipe. The parts of the first and second cooling water passages that are closer to the water jacket than the three-way valve are connected by a second bypass pipe that is equipped with an on-off valve that opens and closes based on the signal from the water temperature sensor in the middle. An automotive heating device characterized by:
