Scale Control System

Rinnai America Corp. has released its Scale Control System, an accessory that helps tankless water heaters perform optimally with hard water, in which mineral deposits can affect a unit’s efficiency and shorten its lifespan. The Scale Control System may be installed on a home’s cold-water line in front or upstream of a tankless unit. The system dissolves a blend of compounds into the water stream, delivering scale control without electricity. The cartridge, which should be replaced every 10 to 12 months, is translucent so owners can see when replacement is necessary.
