ABSTRACT:
A lined water heater storage tank having a welded metallic shell and a bag-like liner within the shell. The welded metallic shell has ports for flow of water into and out of the storage tank, and the liner has fittings corresponding to the ports on the shell for the flow of water into and out of the liner. The fittings on the liner are mounted on the ports on the metallic shell. The bag-like liner prevents contact between water within the liner and the inner surface of the shell.
