Beschreibung
Zusammenfassung:	A compact combined heater and pump is disclosed. There is a pump housing forming an internal pump chamber, the housing having both an inlet and an outlet and an opening therethrough. A drive shaft is rotatably mounted in the opening and is driven by a motor located outside the chamber. An impeller is mounted on the drive shaft within the housing and a heater is sandwiched in the chamber between the motor and impeller. Rotation of the shaft can draw liquid in from the inlet, past the heater and through the outlet. A cooling fan attached to the shaft for rotation therewith draws cooling air over control circuitry and then forces the air over the motor.
