Abstract: A heating apparatus of the invention executes a first heating control for heating a heater core by a heat generation device when a process of heating the heater core is requested while an engine operation is stopped. The heating apparatus executes a second heating control for heating the cooling water which cooled an internal combustion engine, by the heat generation device and supplying the heated cooling water to the heater core when a heater core temperature is not increased to a requested temperature only by the heat generation device. The heating apparatus executes a third heating control for stopping the engine operation, heating the cooling water which cooled the internal combustion engine, by the heat generation device, and supplying the heated cooling water to the heater core when an engine temperature becomes equal to or higher than a predetermined temperature while the second heating control is executed.
