Abstract
An automatic self-cleaning electric or gas water heater has a sloped conical bottom wall and a manifold such that water flowing through the manifold gently washes sediment to the bottom wall. The sediment slides along the bottom wall to a bottom drain. The sediment and water in the tank bottom periodically flow through the drain by operation of a controller which activates a solenoid valve.
