Abstract
When errors occurred that prevented operation of one heater unit in a conventional hybrid type hotair heater, the heating operation was continued by means of the other heater unit although the user could not immediately recognize that error thereby resulting in the possibility that the error condition might remain in the hotair heater. Therefore, an error detection means was installed in each gas and electric heater unit to detect errors that prevent heating operation in each of these heater units. When an error is detected in one heater unit during the heating operation by means of said error detection means, the heating operation of the device stops once. When the operation starts up again, the other heater unit, where said error did not occur, runs and the heating operation continues.
