摘要： A water heater having a water tank and multiple electric resistance heating elements extending into the water tank for heating water in the tank. The water heater includes a proportional band temperature controller for conducting electric power to the electric resistance heating elements in bursts. Each burst of electric power is followed by a period during which the temperature controller does not conduct power to the electric resistance heating element. In one embodiment, each burst of electrical power lasts for about 95% or less of a cycle comprised of one burst of electric power followed by the period during which the temperature controller does not conduct electric power. Further, activation of the heating elements by the controller is carried out in a sequential or other timed or controlled fashion to permit uniform heating of the water in the tank.

摘要： A paperboard container for a hot water heater or similar manufactured article. The container comprising a body having eight sides, a bottom member closing the bottom of the container body, and a top member closing the top of the container body. The bottom member having eight bottom member sides, each bottom member side in contact with one of the eight body sides, having an interior face for supporting and preventing lateral movement of the hot water heater within the container, and having an exterior face for supporting the container on a floor or other surface. A tab on each container body side is attached to the bottom member exterior face for holding the bottom member in place as the container bottom. The container employs only about 85% of the paperboard required in a square cross section container for the same size hot water heater, and has greater strength than the square cross section container.

摘要： An insulated tank construction for a water heater, including a cylindrical tank, a cylindrical shell placed around and spaced radially apart from the tank to form an annular space, and a ring-shaped form dam disposed circumferentially at a selected position in the annular space along the height of the tank. The foam dam is comprised of a resilient compressible material, preferably porous, open-cell polyurethane foam, and has an inner diameter less than the tank outer diameter and an outer diameter greater than the shell inner diameter. Thus, the foam dam is compressed into sealing engagement with both the tank wall and the shell wall. The shell inner wall, foam dam and tank outer wall form an annular chamber within the annular space. Expandable polymer foam material is injected into the annular chamber and expanded to form a jacket of insulating foam around the tank. Initially, gasses generated by expansion of the foam escape the annular chamber through the porous body of the foam dam. However, the fluid polymer foam will not flow through the porous body and the foam dam retains the foaming polymer within the annular chamber. For gas fired water heaters, which have a hot heating chamber at the bottom, the foam dam will prevent flammable polymer foam from contacting the heating chamber.
