An application for a method of heating water includes transferring the water from a water supply into an inner tank of the water heater which is held within an outer tank, transferring the water from the inner tank into an outer tank and then to supply a building with hot water. The water in the outer tank is heated with hot gasses, partially cooling to intermediate temperature gasses. The water in the inner tank is heated with the intermediate temperature gasses, further cooling the intermediate temperature gasses into cooler gasses that are then exhausted out of the water heater.

The water heater of claim 6, wherein the cover plate is affixed to the outer tank by a plurality of bolts. 9. The water heater of claim 6, wherein the means for providing hot gasses is a burner. 10. The water heater of claim 6, wherein the means for transferring hot gasses from the plenum to the plurality of exhaust apertures also conducts heat to water present in the outer tank. 11. A method of heating water comprising: transferring water from a water supply into an inner tank, the inner tank held within an outer tank;transferring the water from the inner tank into an outer tank;supplying hot water to a building from the outer tank;heating the water in the outer tank with hot gasses, the water in the outer tank partially cooling the hot gasses into intermediate temperature gasses;heating the water in the inner tank with the intermediate temperature gasses, the water in the inner tank further cooling the intermediate temperature gasses into cooler gasses; andexhausting the cooler gasses. 12. The method of claim 11, wherein the hot gasses emanate from a burner. 13. The method of claim 11, wherein the step of heating the water in the outer tank is performed by a heat transfer pipe passing through the water in the outer tank. 14. The method of claim 11, wherein the step of heating the water in the outer tank is performed by a heat transfer pipe passing through the water in the outer tank and a plurality of heat exchange tubes, the heat exchange tubes partially exposed to the water in the outer tank. 15. The method of claim 11, wherein the step of heating the water in the inner tank is performed by a plurality of heat exchange tubes passing through the water in the inner tank.
