Abstract: An apparatus for heating and impelling air comprises a housing, an air heating impeller assembly, and a magnetic assembly. The impeller assembly may impel air through the housing and heat the air, and may include a support shaft, a plurality of annular disks positioned along the support shaft and each having a central aperture through which the support shaft extends. The impeller assembly includes paddles radiating outwardly from the shaft, and each of the paddles is positioned between the shaft and the disks to space at least one disk from the support shaft to form an air path therebetween. The paddles space the disks in an axial direction to form gaps therebetween to form an air path between the disks. The magnetic assembly applies a magnetic field of adjustable intensity to the disks to cause heating of the disks.
