Abstract: The present invention is directed generally to heating systems, and more particularly to a new and improved friction heat generator apparatus for converting electrical energy into heat without the use of fossil fuels. The heat generator apparatus comprises a housing which interiorly mounts a heat exchange unit which contains a heat transfer medium (i.e. water) and a fly-force friction drive unit mounted for rotation with a drive shaft for frictionally engaging said heat exchange unit in response to centrifugal force imparted to a fly-weight mechanism upon rotational movement of the drive shaft to provide a rapid and efficient development and transfer of heat to the heat transfer medium for various heating applications.
