What is a self-cleaning hot water heater?
A. The dip tube is what takes the cold water to the bottom of the tank. In self-cleaning models, the dip tube is equipped with a fitting at the bottom that causes a spiraling effect on the incoming water. This dislodges the sediment off the bottom of the tank and lifts it up and out through the hot side. This will increase the tank’s efficiency and help the tank’s glass lining last longer.
