Replaceable adaptor for a hot water tank resistive heating element

摘要

An adaptor assembly for securing a resistive electric heating element to a hot water heating tank. The adaptor assembly comprises a hollow hub sealingly securable with a hole in a hot water tank outer wall with a connecting portion of the hub extending outwardly of the outer wall. At least two opposed retention members are provided in a connecting portion of the hub to receive and removably retain an adaptor plate. The adaptor plate is connectable to a resistive heating element bracket by fasteners to secure the bracket to the plate with a resistive element of the bracket extending in the tank through the hub. The adaptor plate is secured to the hub by interference the retention members of the hub and a seal is disposed between the bracket and the hub and sealingly engaged by the pressure applied by the fasteners.
