Abstract
A heating apparatus for a vehicle includes a pump for circulating cooling water in a cooling water circuit, a heating heat exchanger for heating air blown into a passenger compartment of the vehicle using cooling water as a heating source, and a throttle valve disposed at a discharge side of the pump. In the heating apparatus, when the temperature of cooling water is low and heating capacity for heating the passenger compartment is insufficient, an opening degree of the throttle valve is reduced by a control unit. Therefore, heat is generated from the throttle valve and the pump so that the temperature of cooling water is increased. Thus, heating capacity of the heating apparatus can be improved without using a manual operation.
