PURPOSE:To make interior heating performable without interruption even at the time of engine stoppage, by generating power through a generating device by means of exhaust gas out of a fuel burning heater and charging an electric power unit, while constituting a heating apparatus to drive a blast device with the electric power, feeding the inside of a car room with hot air. CONSTITUTION:At the time of engine stoppage, water is led into a jacket 17 at the heater side by operation of a water pump 15 making a battery 40 a power source and, after being heated by a fuel burning heater 4, it is led into a car heater 5 via a passage 21. And, after heat exchange with air is carried out by this heater 5, this heated water is made to flow back to the suction side of the water pump 15 via a passage 24', a selector valve 24 and a passage 29. On the other hand, a fan 32 is rotated and driven by exhaust gas out of the fuel burning heater 4, driving a generator 36, and electric power obtained here is charged to the battery 40. Then, with current-energization from this battery 40, a heater blower 43 is rotated, this heated air owing to heat exchange by the heater 5 is blown to the car room inside, thus heating takes place. |
