Abstract: An electric integrated circuit water heater apparatus includes: a cold water inlet for allowing input of cold water into a storage tank with heating elements comprised of integrated circuits configured to exchange heat from the heating elements to the water in the storage tank through a heat exchanger, in which heat produced by running the integrated circuits is recovered into the heat exchanger, thereby heating the stored water by using heat from the integrated circuits. A hot water outlet is provided in the upper portion of storage tank such that the water will have passed all of the heating elements prior to exiting the hot water outlet.
