Abstract: A heating control system for controlling heating of a fluid within an associated fluid vessel includes a first sensor responsive to a low fluid level in the fluid vessel and a second sensor responsive to a temperature of the fluid within the fluid vessel. The heating control system also includes a control circuit electrically connected with the first sensor and the second sensor to control electrical power to a heating unit for heating the fluid within the fluid vessel. The control circuit allows electrical power to be connected to the heating unit upon a first predetermined condition of the first sensor and a first predetermined condition of the second sensor. The control circuit disconnects power to the heating unit upon either a second predetermined condition of the first sensor or a second predetermined condition of the second sensor.

Abstract: A heating control system for controlling heating of a fluid contained in a fluid vessel using a fluid level sensor as a heating control element. The system includes a control circuit coupled with an electrical power system of a heating unit. The control circuit includes switching elements that are selectively activated or deactivated responsive to a low fluid level in a corresponding fluid vessel such that heating of the fluid is terminated as the level of fluid becomes less than a predetermined value.
