ABSTRACT:
An electric water heater that includes a metallic housing having a water inlet and outlet, and a non-electrically conducting liner that is impervious to the action of water. First and second carbon electrodes, each in the form of a plate wedge-shaped in cross-section and having an obliquely disposed flat surface, are arranged within the liner with their respective obliques flat surfaces in parallel spaced relation to define a water passage therebetween. Manually operable means permit the second electrode to be moved relative to the first electrode to vary the width of a water passage defined between the electrodes. The housing supports first and second electric terminals that are insulated from one another, but are in electrical communication with the first and second electrodes. The degree to which water will be heated is dependent on the velocity at which the water flows through the passage between the first and second electrodes, and this velocity being determined by varying the width of the passage between the electrodes by use of the previously mentioned manually operated means.
