decreasing a target water temperature of the air heating unit when the contact heating unit is on;
decreasing a total electric power of the electric power that is supplied to the heater of the contact heating unit and the electric power that is supplied to the heater of the air heating unit when the heater of the contact heating unit is on as compared to the electric power that is supplied to the heater of the air heating unit when the heater of the contact heating unit is off; and
