Patent ID: 8532474

Claim:
An electrical liquid heating system, comprising: at least two spaced apart electrical conductors; an electrical energy source applied to said conductors; a liquid path defined between said conductors for bringing a liquid into contact with said conductors thereby delivering electrical energy to the liquid; wherein electrical energy is delivered to the liquid at a power level that is sufficient to generate an electrical current to produce resistive heating of the liquid; and a regulator for regulating the delivery of electrical energy to the liquid, wherein said regulator at least partially disrupts the delivery of energy to a particular volume of the liquid, wherein said regulator creates non-conductive breaks in at least one of said conductors, wherein the liquid path provides for liquid flowing with respect to said conductors and wherein said non-conductive breaks are spaced along substantially the entire said at least one of said conductors in the direction of liquid flow, wherein electrical current is at least partially interrupted by the liquid flowing past said non-conductive breaks.
