ABSTRACT:
An electric water heater includes a cylindrical tank with an inner surface defining a water chamber having a central vertical axis. Three sets of three electric immersion heating extend radially inwardly into the water chamber from the inner surface. The heating elements of such set define generally horizontal planes vertically spaced apart along the vertical axis. The heating elements of each set lie in angularly spaced generally vertical planes intersecting the central axis and being spaced approximately 120.degree. apart with the inner ends of the respective heating elements being in overlapping spaced relationship along the vertical axis to provide the most heat at the center of the chamber where it is most needed.
