ABSTRACT:
A method of making a water heater capable of being hung from a support, which includes a water tank, a water inlet, a water outlet, and a jacket positioned around the water tank so as to define a space between the water tank and the jacket. Foamed insulation is positioned in the space between the water tank and the jacket, and the foamed insulation has increasing density and cell uniformity gradients in a direction running from a first portion to a second portion of the jacket. A curved bracket assembly is positioned on the outer surface of the jacket at the second portion of the jacket to coincide with the positioning of foam insulation having highest density and best cell uniformity. A bumper is optionally positioned on the outer surface of the jacket and is vertically aligned with the bracket assembly.
