ABSTRACT:
An electric heater includes an electric heating coil that extends above the sidewalls of an air flow channel. The coil is formed in sections that extend transversely to the channel and are spaced by the width of a coil section to allow two heaters to be arranged face to face for shipping. This arrangement is very efficient because one of the heaters provides protection to the coil of the other of the heaters to reduce packaging costs.
