ABSTRACT:
A device for heating a liquid includes a tank, electrodes, and a conductive liquid. The tank holds the conductive liquid and the electrodes. The electrodes are connected to provide current flowing in the conductive liquid. The device also includes an electrolytic material supply vessel for holding the electrolytic material. The electrolytic material supply vessel is switchably connected for providing the electrolytic material to the tank. The device also includes an electrical parameter sensor for detecting a parameter of electrical energy dissipated in the conductive liquid. The device also includes a controller connected to automatically add the electrolytic material to the conductive liquid if the electrical parameter sensor detects the electrical parameter differing from a set point.
