ABSTRACT A water heater comprising a water tank having a component intended to be kept substantially free from contact with an expandable foam insulating material, and a method of making same, is provided. The water heater has a jacket surrounding the tank and providing an insulating space therebetween. Positioned within this space is a pair of flexible sheets forming an apron. The sheets are joined to form a seal protecting the component from contact with the foam. The apron is positioned over a part of the tank surface so that the seal surrounds the component. The sheets of the apron are substantially unsealed along their top and sides, Foam is introduced between the sheets of the apron and flows out of the unsealed sides of the apron to fill the space between the tank and the jacket. A method of insulating a water heater with an expandable foam insulating material is provided. The expandable foam insulating material has an initial viscosity of < 300 cps, a flow index ? about 0.7, a gel index ? about 0.8 and generates a maximum pressure of ? about 1.0 psig. The foam is injected into the annular space between the water tank and the outer jacket. Preferably, the foam is injected into a sleeve, which acts to confine the foam during its most liquid state, positioned within this space. The foam is preferably injected into the annular space between the tank and the jacket while the top cover is removed. In this way, the injected foam can be distributed more evenly around the circumference of the tank. A water heater comprising a water tank having a jacket surrounding the tank and providing an insulation space therebetween. A plurality of serial foam injections are introduced into the space to fill the space between the tank and the jacket.
