All water heaters and heat exchangers need a periodic descaling flush to maintain optimal performance. BucketDescaler® industrial descaler system makes descaling heat exchangers fast and easy. Remove limescale buildup from heater elements and heat exchangers in minutes, not hours with BucketDescaler. Use with SpeedyBright™, our industrial descaler classified by UL to NSF/ANSI Standard 60, for superior results. Over 50% of the U.S. uses moderate to hard water, which contains high levels of calcium carbonate and other minerals. Without proper maintenance, a new tankless water heater or heat exchanger can lose over 50% of its efficiency in the first 6 months alone! That’s where BucketDescaler comes in. Descale a standard water heater, heat exchanger or on-demand tankless water heater in about 30 minutes or less. Get step-by-step instructions on how to use a descaler for a tankless water heater. Simply attach the portable, acid-proof and self-contained industrial descaling unit to the in/out water connections and circulate with safe and environmentally friendly, SpeedyBright. This system will remove limescale from units in minutes. You’ll see the difference in no time. The Bucket Descaler quickly circulates our SpeedyBright cleaner, maintaining its powerful action through constant agitation. It eliminates scale, rust, lithium carbonate, calcium and more on contact, returning any heater to near peak efficiency in minutes. And for bigger units, add our optional valve kit. This allows you to draw more clean water from an auxiliary bucket. Perfect for larger water heaters and heat exchangers. By combining industrial-strength technology with a compact, durable design, Bucket Descaler makes cleaning tankless water heaters, heat exchangers and water boilers quick and easy.
