QwikDescaler+ restores full efficiency to heat exchangers, heaters, tankless water heaters and any other appliances where flow passages must be kept free of mineral deposits. Keeping heating passages free of mineral deposits significantly improves efficiency, conserves energy, reduces energy costs and extends the life of equipment. Unique Color indicating Chemistry...Tells you when more Descaling solution is needed and when cleaning is complete. At working strength, the descaling solution will appear reddish. When the descaling solution is exhausted and no longer working, it turns yellowish indicating that more QwikDescaler+ should be added. The system is clean when the reddish color is retained for 10 minutes. Safely restores equipment to full efficiency and opens flow passages. Calcium scale deposits cause significant reductions in heat transfer, resulting in reduced efficiency, reduced capacity and increased energy costs. A thin layer of scale, as small as three hundredths of an inch (0.03 inch), can increase energy consumption and the cost of operation by 30%. The Descaler Kit Has everything needed for cleaning tankless water heaters that have 3/4" garden hose service connections, including a mixing container, quart of concentrated Descaler solution, circulation pump (500 GPH) and necessary hoses. 1 quart makes 6 quarts.
