Abstract
An improved viscous fluid type heater is disclosed. The heater has a heating chamber and a heat exchange chamber. The heating chamber accommodates viscous fluid and a rotor that rotates and shears the viscous fluid to produce heat. The heat exchange chamber allows circulating fluid to flow therethrough, whereby the heat is transmitted to the heat exchange chamber from the heating chamber to heat the circulating fluid. A reservoir chamber communicates with the heating chamber for an auxiliary reservoir of the viscous fluid. A stirring member is provided in the reservoir chamber and stirs the viscous fluid in the reservoir chamber.
