An improved water heater is shown which includes a water heating tank having external cylindrical sidewalls, an interior, and initially open upper and lower ends. A combustion chamber is connectable to the water heating tank and houses a burner for the combustion of a selected fossil fuel. A fire tube unit of a fixed length is received within the interior of the water heater tank and has an upper transverse wall section, a lower transverse wall section and interconnecting fire tubes. The fire tubes have open interiors which receive the products of combustion from the combustion chamber for heating water contained in the water heating tank. Flanges and resilient seals are located at the upper and lower ends of the water heating tank for securing the fire tube unit within the interior thereof. The resilient seals can be selectively sized to accommodate dimensional tolerances which occur between the fixed length of the fire tube unit and the water heater tank, allowing the components to be assembled in modular fashion.

Modular vertical tube tank and method of manufacture

A potable, hot water storage vessel is shown with a metallic body having a water inlet, water outlet and at least one additional opening communicating the vessel interior and exterior. A flexible, non-molded liner is installed within the vessel interior through the additional opening. The liner has integrally formed ports which extend through the vessel inlet and outlets to the exterior of the vessel body. A bolt-on flange is received on the vessel exterior at the inlet and outlet to form a seal with each of the liner ports.
