ABSTRACT:
Hot water pipes, in areas with hard water, tend to fill with scale until they no longer pass enough water. De-scaling water pipes with acid is dangerous, expensive and damages the pipes. Ion exchange and reverse osmosis water softeners eliminate scale buildup in pipes, but are expensive. This invention is a means of keeping the scale precipitate, created when water is heated, inside the water heater by passing the hot water through a removal medium where the scale sticks to the surface. The removal medium can be placed inside the water heater or in a separate tank connected to the water heater; both configurations remove the precipitate from hot water; both save hot water pipes from scale accumulation.
