Foam insulated water heater and method of making same |
摘要 |
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 components 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 the top and a side. Foam is introduced between the sheets of the apron and flows out of the unsealed side of the apron to fill the space between the tank and the jacket.
