SYSTEM AND METHOD FOR IMPROVED HEATING OF FLUID

摘要

An apparatus for heating fluid comprises a preheat reservoir. Fluid such as water in the preheat reservoir is heated by passing current through at le ast one pair of reservoir electrodes between which an electric current can b e passed through fluid in the preheat reservoir, to heat fluid in the reserv oir to a preheat temperature. The preheat temperature is less than a desired output fluid temperature of the apparatus. Fluid from the preheat reservoir flows to an outlet of the apparatus via an outflow temperature boost passag e. The outflow temperature boost passage has electrode pairs between which a n electric current can be passed through fluid in the outflow temperature bo ost passage, to heat fluid dynamically in the outflow temperature boost pass age to the desired output fluid temperature. The apparatus can adapt to vari ations in input fluid conductivity as well as the specific conductance gradi ent of fluid as it heats within the apparatus.
