ABSTRACT:
Apparatus and method of insulating a water heater that utilizes a foaming apron comprised of substantially parallel flexible sheets having an open end and open edges. One sheet is attached to the wall of a water tank and the space between the sheets is open to receive one or more charges of foam forming liquid. Preferably one pouring is performed in conjunction with an open centering template, thereby creating a uniform sealing insulatio layer around the water tank which protects the control mechanisms from the foam. After one charge has solidified sufficiently to maintain the jacket properly centered, the centering template may be removed and one or more further charges of foam forming liquids introduced.
