To prevent a water heating heater for heating water from heating excessively, in a case where waste heat from an engine can be utilized.SOLUTION: Cooling water is circulated through a water heating heater 12 and a heater core 14 to an engine 10 and then heating in a vehicle interior is performed by the heater core 14. A control part 30 includes a received heat amount calculating part that calculates received heat amounts by cooling water according to amounts of waste heat from the engine 10 at the time of activating the engine 10, and further is provided with a cooling water amount detecting part (a flow meter 28) that detects amounts of cooling water circulated into the engine, which controls output of the water heating heater 12, on the basis of the calculated received heat amounts by cooling water and the detected amounts of cooling water, when the engine 10 is activated, during operation of the water heating heater 12.SELECTED DRAWING: Figure 1
【課題】エンジンからの廃熱を利用できる場合において、水加熱ヒータによる加熱しすぎを防止する。【解決手段】冷却水を水加熱ヒータ12、ヒータコア14を介し、エンジン10に循環し、ヒータコア14により車室内の暖房を行う。制御部30は、エンジン10の作動時におけるエンジン10の廃熱量に応じた冷却水受熱量を算出する受熱量算出部を含む。また、エンジンへ循環する冷却水量を検出する冷却水量検出部(流量計28)が設けられている。そして、水加熱ヒータ12作動中に、エンジン10が作動している場合には、算出した前記冷却水受熱量と、検出した前記冷却水量とに基づき、水加熱ヒータ12の出力を制御する。【選択図】図1
