Problems solved by technology

This technique accommodates changes in the amount of exposed steel in the enclosure, but not in water conductivity levels
Furthermore, this technique can be problematic in high conductivity waters where currently produced titanium electrodes and mixed metal oxide films tend to drift in their reference voltage measurements

Abstract

A water heater having a powered electrode and a method of controlling the water heater. The water heater includes a tank to hold water, a heating element, an electrode, and a control circuit. The control circuit includes a variable voltage supply, a voltage sensor, and a current sensor. The control circuit is configured to controllably apply a voltage to the electrode, determine the potential of the electrode relative to the tank with the voltage sensor when the voltage does not power the electrode, determine a current applied to the tank after the voltage powers the electrode, determine a conductivity state of the water in the tank based on the electrode potential and the current, and define the voltage applied to the powered electrode based on the conductivity state. The control circuitof the water heater can also determine whether the water heater is in a dry-fire state.

Description

[0001] This application is a divisional application of an invention patent application with an application date of September 27, 2005, an application number of 200510107086.9, and an invention title of "water storage device with energized anode". technical field [0002] The present invention relates to a water storage device having a powered anode and a method of controlling a water storage device. Background technique [0003] Energized anodes have been used in the water heater industry. In order to work properly, energized anodes generally must solve two main problems. First, the energized anode should provide enough protective current to protect the exposed steel in the tank. The degree of exposed steel will vary from case to case and will vary throughout the life of the case. Second, the protective current produced by the energized anode should be low enough to reduce the possibility of excess hydrogen. [0004] There are at least two technologies currently in the wa...
