OneFlow Anti-Scale System For Tankless Water Heaters for up to 10 gpm (38 lpm)
Series OFTWH OneFlow® Anti-Scale System provides protection from scale formation on internal and external plumbing surfaces. OneFlow is a single cartridge-based system that must be installed on a cold water line prior to a waterheating device (water heater or tankless water heater) for single tankless heaters. The system prevents scale by transforming dissolved hardness minerals into harmless, inactive microscopic crystal particles. These crystals stay suspended in the water and are passed to the drain. The OneFlow system requires very little maintenance, no backwashing, no salt, and no electricity. Typical hardness problems, especially buildup of scale on heating elements, pipes, water heaters, boilers, and fixtures, are no longer a concern.
