Tankless water heater manufacturer Noritz America recently released an updated version of its hard water-treatment product, Scale Shield. Upgrades offered include a built-in sediment filter, two cartridge pressure gauges, a more efficient treatment medium, plus universal compatibility and connection to Noritz residential models. The updated Scale Shield is sold in a kit (SS-HB-3) via wholesaler-distributors or on the Noritz website. The kit holds a 12-month warranty for parts only.
The original Scale Shield aids in preventing the buildup of hard water minerals, while eliminating the need for a water softener. Hard water contains dissolved calcium and magnesium that, when heated, are released in the form of a chalk-like material. This chalk coats pipes, fixtures and fittings, creating an insulating layer that leads to lower efficiency and system malfunction.
