Hard Water Costly, Study Shows

Preliminary results of a study funded by the Water Quality Research Foundation (WQRF) shows that hard water can reduce the efficiency of instantaneous water heaters by as much as 6% after only 15 months of average household use.

This final report on this study is due on September of 2009.
