Lindahl, J R

To prevent the accumulation of scale and other solid particles in its bottom portion, this water heater incorporates a specially designed agitator assembly that is cheaper and simpler to use than electrostatic, electronic, or chemical devices. A ring-shaped tube positioned at the bottom of the tank close to the side wall is connected to a second tube that extends toward the tank's center. Openings and venturi fittings on the two tubes cause the water to flow into to the tank horizontally and centrally upward, creating a stirring action at the tank bottom.
