After an eight-week follow-up by us, accompanied by the Head of Maintenance, visual observation on the hot water tank and pictures. We found that the resistance and the walls of the tank were clean. The scale had loosened and fallen off, and it was a friable proof of the effect of the Vulcan treatment.
Every 6 months the engineering staff had to manually remove scale from pumps, valves, kitchen equipment and from the 102 individual electric hot water heaters. After installing the Vulcan descalers scale was easily flushed out. After a second inspection the units were found to be almost entirely free of scale.
I believe we have quadrupled the life span of our evaporated air conditioner and we haven't had to replace our hot water system for more three years. Without the Vulcan Descaler Treatment System we would be replacing our hot water system every two years at a cost of more than $10,000.
