ABSTRACT:
The inner surface of a hot water storage vessel is lined with a removable rigid plastic liner layer with injected foam insulation located between the liner and storage vessel. A heat exchanger is mounted through an integral first flange to a second flange integral with the liner. In turn, the second flange is mounted to a third flange integral with the storage vessel. Fittings on the first flange permit entry into the water containing chamber for inlet and outlet piping as well as for thermostats and pressure relief valves. No piping passes through the liner or storage vessel.
