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.

Abstract: A water heater appliance includes a tank extending along a vertical direction between a top end wall and a bottom end wall and a dip tube extending from an inlet end to an outlet end. The inlet end of the dip tube is coupled to a cold water inlet in the top end wall of the tank. The outlet end of the dip tube may be positioned in a bottom corner of the tank and/or positioned at an outer perimeter of the bottom end wall.

Abstract: A water heater appliance is provided that includes features for removing water from a junction box of the water heater appliance. More particularly, a water heater is provided that includes a draining feature that drains or removes water that has seeped or leaked into a junction box that is at least partially encased in an insulation material. In one exemplary aspect, the drain feature includes a drain conduit connected to an outlet defined by the junction box. The drain conduit may drain the water from the junction box to a number of suitable locations. For instance, the water may be drained to a dedicated drain port or a cavity defined in part by an access panel removably mounted to a casing of the water heater appliance.

Abstract: A water heater appliance is provided that includes features that facilitate centering a tank within a casing of the water heater while also diminishing heat loss through the bottom of the water heater. More particularly, a water heater is provided that includes a bottom cover that has an integral centering feature that facilitates centering of the tank within the casing. A method for assembling a water heater appliance is also provided.

Abstract: A water heater appliance is provided that includes features for preventing water incursion into an access point or ingress of water heater appliance. More particularly, a water heater is provided that includes a boot that stretches around an incoming supply conduit to form an impermeable seal at the interface between the boot and the supply conduit. The boot has a canopy that extends from the impermeable seal to a canopy edge contacting at least a portion of the casing. The boot sheds water away from the access point and thus prevents water from entering the water heater appliance through the access point.

Abstract: The present subject matter provides chiller apparatus including a storage tank for storing the liquid and a refrigerant cooling system. The refrigerant cooling system includes a compressor attached to the storage tank, a condenser positioned downstream from the compressor to condense a refrigerant received therefrom, and at least one evaporator positioned downstream of the condenser and wrapped about the outer surface of the storage tank. The evaporator includes a negative pitch coil configured to direct refrigerant flow from a position near a top of the storage tank to a position near a bottom of the storage tank.

Abstract: A dam assembly for positioning around a fitting in a water heater defines an axial direction and includes a hollow extension. The hollow extension extends along the axial direction and includes a body portion positioned at a first end, a frangible section positioned at a second end, and a detachment band extending along the axial direction between the body portion and the frangible section. The frangible section is configured to be removed from the body portion along the detachment band to reduce an effective length of the hollow extension and allow the dam assembly to be used in various locations in a single water heater appliance and/or in various size water heater appliances.

Abstract: Water heater appliances are provided. A water heater appliance includes a tank defining a chamber, the tank further defining an inlet aperture and an outlet aperture. The water heater appliance further includes a cold water conduit extending through the inlet aperture and in fluid communication with the chamber of the tank, the cold water conduit configured for directing a flow of water into the chamber of the tank. The water heater appliance further includes an alignment feature configured on the cold water conduit for orienting the cold water conduit within the chamber, the alignment feature corresponding to a mating alignment feature configured on the inlet aperture.
