13 As for water heaters, the researchers found that when they used softened water, the units maintained their original factory efficiency rating for as long as 15 years. Running hard water through the units cut efficiency by up to 48 percent. Scale buildup shortened the lifespan of the heating elements inside electric water heaters, and some tankless water heaters using hard water failed after just 1.6 years! The researchers found that showerheads performed well on soft water, but those running with hard water lost 75 percent of their flow rate in less than 18 months. When running hard water through faucets, the strain- ers on the faucets clogged within 19 days. Softened water can save you money by keep- ing appliances at top efficiency, and making them last longer. The amount of dish and laun- dry detergent you use can be cut by half, or even more, if you use softened water. You can also lower wash temperatures from hot to cold without a drop in performance, according to two other independent studies. Studies conducted by the independent test firm Scientific Services S/D, Inc., of New York, showed that using softened water can: ✓ Reduce detergent use by 50 percent in washing machines and save energy by making it possible to wash in 60ºF cold water instead of 100ºF hot water, while achieving the same or even better stain removal along with whiter clothes. ✓ Achieve the same cleaning results in dishwashers while using less than half the detergent.
