摘要：Heating apparatus comprises an air inlet, at least one air outlet, an impeller, a motor for rotating the impeller to draw air through the air inlet, a user interface for allowing a user to select a rotational speed of the motor from a user selectable range of values, and at least one heater assembly comprising at least one positive temperature coefficient (PTC) heating element for heating air passing from the air inlet to a respective air outlet. The magnitude of a current drawn by the at least one heater assembly is detected, and the rotational speed of the motor is controlled independently from the rotational speed selected by the user depending on a characteristic of the current drawn by the at least one heater assemblies.
