Abstract

A hot water tank is comprised of a cylindrical disc-shaped support base on which is supported a cylindrical inner tank concentrically therewith. A circumferential ridge projects upwardly adjacent an outer peripheral edge of the support base and spaced from a lower edge portion of a circumferential side wall of the inner tank to form a circumferential containment channel between the ridge and the lower edge portion. The channel has a volume sufficient to receive a lower portion of a plastic film pouch wrapper disposed at least about a lower section of the inner casing as well as a pre-determined quantity of hot expandable liquid urethane placed therein in sufficient quantity to fill a space between the inner casing and an outer shell secured spaced about the inner casing when the urethane is expanded. The channel prevents the liquid urethane from flowing out of the lower portion of the wrapper located therein due to deterioration of the wrapper when exposed to the hot liquid urethane.
