ABSTRACT:
A combined heating and water inlet/outlet assembly for installation in a bottom opening of a domestic water heater tank includes a plastic mounting flange adapted to cover the opening and a plastic open-top cylindrical sleeve extending upwardly therefrom and adapted to project into the tank through the opening. An electric immersion heating element is removably carried by the flange and projects into the sleeve. Integrally formed water inlet and outlet tubes extend along the outer generatixes of the sleeve. A second, plastic, closed-top cylindrical unit is received on top of the sleeve to form an extension of thereof. An integral tubular section along the outer surface of the cylindrical member forms an extension of the outlet conduit. The closed top of the cylindrical member has an integral upwardly extending riser tube forming an outlet for water heated by the heating element. A series of integrally formed pairs of parallel plastic tube lengths fit one on top of the other and on top of the tubular outlet and riser tube section to form extensions thereof up to the top wall of the tank. A valved opening is provided in the cylindrical member for introducing water thereinto from the tank and permitting shutting off the water flow into the cylindrical member for replacing the heating element without need to empty the whole tank.
