Scale agitator

摘要

A scale agitator for tank type liquid heaters employs a flexible non-cathodic tube through which liquid can flow. The liquid can be obtained from the tank or the supply of makeup liquid to be heated can be used. The tube may be fastened to a clean-out cover mounted to the exterior of the tank so that the tube can be inserted into and removed from the tank through the opening behind the clean-out cover.
