Abstract
A method for insulating a gas-fueled water heater includes providing a tank for storage of water for heating and a combustion chamber adjacent to the tank. The method includes providing a compressed foam barrier circumferentially around the tank. Further, the method includes positioning a covering around the tank from a top end to a bottom end, the covering extending over the compressed foam barrier. Moreover, the method includes decompressing the compressed foam barrier such that an outer diameter of the foam barrier expands up to and seals against the covering so as to separate an internal volume defined between an outer surface of the tank and the covering into a first section and a second section. Then, the method includes injecting a foam material into the first section so as to provide a foam barrier around at least a portion of an outer surface of the tank.
