System and method for improved heating of fluid

Abstract

An apparatus for heating fluid, includes a preheat reservoir having at least one pair of reservoir electrodes between which an electric current can be passed through fluid in the preheat reservoir, to heat fluid in the reservoir to a preheat temperature, the preheat temperature being less than a desired output fluid temperature of the apparatus; and an outflow temperature boost passage through which fluid from the preheat reservoir flows to an outlet of the apparatus, the outflow temperature boost passage having at least one pair of outflow electrodes between which an electric current can be passed through fluid in the outflow temperature boost passage, to heat fluid dynamically in the outflow temperature boost passage to the desired output fluid temperature.
