ABSTRACT:
In the heater of the present invention, a heating chamber accommodates a viscous fluid. A rotor is located in the heating chamber. The rotor rotates and shears the viscous fluid to generate heat. The heat generated in the heating chamber is transferred to the heat exchanger and heats a fluid that flows through the heat exchanger. A reservoir stores the viscous fluid. The reservoir has an upper portion and a lower portion, and the lower portion has a greater volume than the upper position. A return passage connects the heating chamber to the reservoir so that the viscous fluid moves from the heating chamber to the reservoir when the rotor rotates. A supply passage connects the reservoir to the heating chamber so that the viscous fluid flows from the reservoir to the heating chamber.
