Tankless water heater manufacturer Noritz America recently released an updated version of its revolutionary hard water-treatment product, Scale Shield. The original Scale Shield aids in preventing the buildup of hard water minerals while eliminating the need for a water softener. The updated Scale Shield is sold in a kit (SS-HB-3) via wholesaler-distributors or on the Noritz website and includes a wall bracket, wrench, lubrikit, pressure gauge and one HBC-3 cartridge. Individual cartridge replacements can be found on the website as well. The Scale Shield kit also holds a 12-month warranty for parts only.
