摘要:
A method for insulating a water heater with foamed insulation comprises inflating a tube in the cavity between the shell and the tank to define a boundary for the cavity into which the insulating material is injected. The device is deflated after the foamed insulation has set in the cavity. Apparatus for carrying out such method is provided.
