PROBLEM TO BE SOLVED: To provide a vehicle heating apparatus that is improved in comfortability by adjusting, based on calorie, which air blown out from a plurality of heater units has, the quantity of warm air blown into a vehicle interior. ! SOLUTION: The vehicle heating apparatus, which heats a vehicle using cooling water of an internal combustion engine, comprises: a heater unit 3 having a heater fan 31 that exhausts warm air heat-exchanged in a built-in heat exchanger into the interior of the vehicle; a first temperature sensor 11 that detects temperature of cooling water to be introduced into the heater unit 3; a second temperature sensor 12 that detects temperature of the cooling water to be drained from the heater unit; and a fan rotation speed control device 8 that changes rotation speed of the heater fan 31 on the basis of a detection temperature difference between the first temperature sensor 11 and the second temperature sensor 12, where the fan rotation speed control device 8, when the detect |
