A water heater having a magnetic device connected to a source of water under pressure and to the water heater inlet. The magnetic device includes a plurality of permanent magnet members mounted on a tube. Water flowing thru the tube to the water heater inlet will flow thru the magnetic lines of force produced by the permanent magnet members. An agitator assembly is mounted in the bottom portion of the tank and includes a ring-shaped tubular member and a secondary tubular member connected to the ring-shaped tube. The ring-shaped member is provided with a plurality of openings in the sides thereof and the secondary tubular member is provided with an upwardly facing opening therein. The agitator assembly is connected to the magnetic device so that when hot water is periodically withdrawn from the top of the tank, water will flow into the tank from the magnetic device and then out thru the openings in the agitator assembly to produce a stirring action in the bottom of the tank.

A water heater for heating water containing iron molecules comprising: a water tight tank means adapted to contain water under pressure; a source of heat for heating water inside said tank means; a hot water outlet means located in the top portion of said tank means for periodically withdrawing heat

A water heater for heating water containing iron molecules comprising: a water tight tank means adapted to contain water under pressure; a source of heat for heating water inside said tank means; a hot water outlet means located in the top portion of said tank means for periodically withdrawing heated water from the top portion of said tank means; a cold water inlet means located in the bottom portion of said tank means for admitting cold water into said tank means when hot water is withdrawn from said hot water outlet means; a magnetic means having an inlet connected to a source of water under pressure and an outlet connected to said cold water inlet means, said magnetic means including a flow passageway means extending between said inlet and said outlet and a plurality of permanent magnet means mounted on said flow passageway means and spaced along the length thereof, each of said permanent magnet means producing magnetic lines of force which pass through the interior of said flow passageway means so that water flowing thru said flow passageway means will pass thru said magnetic lines of force, said flow passageway means of said magnetic means being in the form of a tubular member made of non-metallic material, said permanent magnet means including spaced sets of doughnut-shaped permanent magnets mounted on said tubular member, each of said spaced sets of permanent magnets having a north pole on one end face thereof and a south pole on the other end face thereof, said permanent magnets producing lines of flux which extend parallel to the direction of flow of water through said tubular member, spacer members of non-magnetic material are positioned between each group of doughnut-shaped permanent magnet members and said magnetic means includes a jacket made of non-magnetic material mounted on said tubular member and enclosing said permanent magnet members and spacer members; an agitator assembly means mounted in the bottom portion of said tank, said agitator assembly means including a tubular member connected to said cold water inlet means, said tubular member extending into said water tight tank means and having a plurality of small openings therein spaced along the length thereof to direct multiple streams of water under pressure into the tank each time water is drawn out of the top portion of said tank means through said hot water outlet means, said plurality of openings in said tubular member positioned so that said multiple streams of water will be directed to sweep over the bottom of the tank means to create a stirring action in the lower portion of said tank means to thereby cause solid materials which have either settled to the bottom or are in the process of settling to the bottom to be maintained in suspension in the water so that ultimately at least a portion of such materials will be carried upwardly in said tank means and out said hot water outlet means, the relationship of the aggregate size of the small openings in said tubular member to the size of said tubular member itself is such that the velocity of the water flowing into said tank means through said plurality of openings in said tubular member is greater than the velocity of water flowing into said tubular member from said cold water inlet means to thereby create the desired stirring action in the bottom portion of said tank means.
