Abstract

A water heater inlet conduit having a top end portion configured to be coupled to an inlet port of a water heater is provided. The bottom end portion of the inlet conduit is configured to extend into an interior of the water heater. A passage within the inlet conduit is provided for water flow from the top end portion to the bottom end portion. The top end portion of the inlet conduit defines at least one outlet opening configured to divert a portion of the water flow outwardly from the passage in the top end portion of the inlet conduit. The top end portion of the inlet conduit further defines at least one inlet opening configured to draw water inwardly into the passage in the top end portion of the inlet conduit.

Claims

1. A method for delivering water into a water heater comprising the steps of:

diverting a portion of water flow from a passage of an inlet conduit and into a top interior segment of the water heater;

drawing water from the top interior segment of the water heater into the passage of the inlet conduit; and

delivering water flow from the passage of the inlet conduit into a bottom interior segment of the water heater through an outlet opening of the inlet conduit.

2. The method of claim 1, further comprising the step of diverting a portion of the water flow from the passage of the inlet conduit and into a bottom interior segment of the water heater through an outlet opening spaced from the bottom end of the inlet conduit.

3. The method of claim 1, further comprising the step of drawing water from the bottom interior segment of the water heater into the passage of the inlet conduit.

4. An inlet configured for use in a water storage tank of a water heater, said inlet comprising:

an inlet conduit having a top end portion configured to be coupled to an inlet port of the water storage tank, a bottom end portion configured to extend into an interior of the water storage tank, a passage for water flowing from said top end portion to said bottom end portion, and an outlet opening at a bottom end of said inlet conduit;

means located at said top end portion of said inlet conduit for diverting a portion of the water flow from said passage of said inlet conduit into the water storage tank;

means located at said top end portion of said inlet conduit for drawing water into said passage of said inlet conduit from the water storage tank; and

means located at said bottom end portion of said inlet conduit and spaced from said outlet opening for diverting a portion of the water flow from said passage of said inlet conduit into the water storage tank.

5. The inlet of claim 4, said water drawing means comprising an inlet opening defined by said inlet conduit.

6. The inlet of claim 4, said water flow diverting means comprising an outlet opening defined by said inlet conduit.

7. The inlet of claim 6, said water flow diverting means further comprising a notch formed in said conduit and extending into said passage.
