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 The agitator assembly is connected to the magnetic device so that when hot water is periodically withdrawn from the top of the tank, water will flow into the tank from the magnetic device and then out thru the openings in the agitator assembly to produce a stirring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.

Water heater with combination magnetic and agitator means

A solar water heating system including a solar collector panel and a combination storage tank and heat exchanger unit for receiving liquid heated in the solar collector panel. The collector panel includes a collector plate made from a pair of steel plates welded together and having a heat absorbing porcelain glass coating on the surface thereof which is exposed to the suns rays. The heat exchanger unit is comprised of a storage tank containing the water to be heated and a plurality of vertically extending heat exchange tubes mounted inside and sealed from the water in the storage tank. The liquid heated in the collector plate is circulated by a pump unit through a first conduit connected between the bottom of the heat exchange tubes and the inlet of the collector plate and through a second conduit from the outlet of the collector plate to the top of the heat exchange tubes. An air transfer conduit is connected in parallel flow relationship with the second conduit to facilitate complete and rapid drainage of the collector plate and exposed piping when the circulation pump is shut off.
