Batelle study proves water softener benefits
The Batelle study (available on the Water Quality Association website), involved the testing of gas storage heaters, gas instantaneous water heaters, faucets, washing machines and other appliances. The results were:
All the water heaters on softened water maintained their original efficiency throughout the testing. All shower heads, faucets, dishwashers and washing machines also remained clean throughout the testing period
The gas instantaneous boilers dropped in efficiency by 8% in just 1.6 simulated years and had to be descaled to maintain flow. The electric storage heater maintained efficiency but had double the amount of scale formed than that of the storage heater, likely to result in premature element failure. Shower heads were nearly unusable in the equivalent of 16 months. Faucets dropped after 19 days of testing. Dishwasher and washing machines were fouled.
The WQA is now pursuing Energy Star markings for softeners and have named water softeners as “one of the best energy saving devices you can buy.”
