ABSTRACT:
A crescent shaped exchanger tank is fitted over the top portion of an electric motor which drives a centrifugal pump. The inlet to the pump is connected to a drain on a bath tub and the discharge of the pump is connected to jet nozzles along the sides of the tub. The heat exchanger has an inlet connected to the high pressure side of the pump and a discharge connected to low pressure or suction side of the pump. The heat of the motor heats the water circulated in the tank to warm the water delivered through the jet nozzles to the tub.
