ABSTRACT:
A water heater construction and method for commercial and residential use includes a generally cylindrical inner water tank surrounded by a layer of insulation. The third component in the assembly is an outer shell which is configured as a hinged combination of two halves or flexible sheet which can be opened radially so that the outer shell may be placed around the layer of insulation and inner tank without requiring any relative axial movement between the outer shell and the inner tank. After the outer shell halves are spread apart and the outer shell is moved into position against the insulation, the hinged halves (or sheet) are then closed towards each other compressing a thickness of insulation and the free ends of the hinged halves are ultimately secured together such that the resultant outer shell is generally cylindrical and generally concentric with the inner tank. The insulation may be joined to the shell prior to assembly of the shell around the tank.
