ABSTRACT:
A heater adapted to be disposed in a vessel whereby to heat liquids contained therein. The heater includes a sealed heat-transmitting cannister that is adapted to be immersed in a vessel containing a liquid media. A foraminous PTC thermistor is disposed in the cannister and electrically insulated therefrom. The thermistor is supported in the cannister by a pair of braces resting upon the inside wall surface of the cannister and each brace includes a pair of facing channels engaging the edges of the thermistor. Electrical connections are provided to convey current to opposite sides of said PTC thermistor. A quantity of electrically inert vaporizable fluid of a predetermined boiling point partially fills the cannister to a level covering the thermistor whereby when current is passed to opposite sides of said PTC thermistor, the fluid will boil and then condense upon the walls of the cannister and give up its latent heat of vaporization and radiate heat into said vessel. The anomoly point of the PTC is at or above the boiling point of the fluid.
