Abstract: A method for generating heat includes passing a liquid between electrodes connected to an alternating current power supply. The liquid must have a sufficient level of electrolytes or dissolved minerals so as to be effectively heated. The level of current applied to the electrodes is preferably monitored and controlled. Exothermic, electrochemical reactions occur within the liquid and at the surface of the electrodes. More particularly, the electrodes are comprised of a material that can be oxidized, and the oxidation process during operation of the heater supplies additional current to heat the liquid.

Abstract: A diathermal water heater for the rapid and controlled heating of water and like fluids. A diathermal heating chamber uses electrical oscillations to heat liquids flowing through it. By means of feedback circuitry, the electrical oscillations are controlled to provide liquids at a constant temperature. Household and industrial quantities of hot water, wet steam and dry steam may be generated by the water heater. The heater itself is compact and can be used to provide one pipe plumbing to provide water at controlled heated temperatures.
