A permanent magnet eddy current heat generator apparatus has a thermally insulated working fluid reservoir containing a working fluid and an enlongate stationary ferrous metal tube disposed in the reservoir with an elongate permanent magnet rotatably mounted inside the tube that, upon rotation, causes the tube to become heated due to the eddy current generated in the tube side wall and the heat from the tube side wall is transferred to the working fluid in the reservoir. An elongate working fluid heat pipe has a first end connected with a working fluid reservoir outlet and a second end connected with a reservoir inlet. The elongate permanent magnet is rotated by the shaft of a motor electrically and magnetically insulated from the working fluid and elongate permanent magnet. A pump, also driven by the motor shaft, is connected in fluid communication between the working fluid reservoir outlet and the heat pipe to conduct working fluid in a closed loop from the reservoir, through the heat pipe, back into the reservoir, and around the exterior of the ferrous metal tube. The heat pipe is placed in heat exchange relation in a second fluid (liquid, air or gas to be heated, such as in a hot water tank, and the heat of the working fluid conducted through the heat pipe is transferred through the heat pipe side wall to heat the second fluid.
