Noritz SS-HB-3 Scale Shield Water Treatment
Tankless water heater manufacturer Noritz America recently released an updated version of its revolutionary hard water-treatment product, Scale Shield. As the leader in energy savings and superior hot-water delivery, Noritz continues to lead with innovation in an ever-evolving tankless water heater industry. The original Scale Shield aids in preventing the build-up 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.
Noritz has taken this original Scale Shield and incorporated innovations to bring this superior product to the next level with the following upgrades:
- Sediment filter: Built into the new Scale Shield, a sediment filter removes particulate matter from the water. This 5-micron filter sifts through the debris while introducing the polyphosphate additive to the water. This additive, coats the calcium particulates, preventing them from releasing from the water when heated; instead, they go harmlessly down the drain.
- Cartridge gauge: Two pressure gauges allow the homeowner to check pressure levels manually. As the particulate matter and debris collect within the filter, the build-up causes water-pressure loss in the house, indicating that a replacement filter is needed. To replace the filter, the homeowner simply unscrews the housing, removes the old cartridge, and replaces it with a new one.
- Efficient material for water treatment: The new Scale Shield also uses a different treatment medium than its predecessor. A bead-like material replaces the original’s powdery substance, increasing the efficiency of water treatment and reducing corrosion caused by chlorides, silica, and dissolved iron. Although Noritz recommends a 12-month replacement timeframe at 15-grain hard water or less, the increase in media size offers a slightly extended lifespan for the product.
- Compatibility and connections: The new Scale Shield is compatible with all Noritz residential tankless water heaters and combination-boiler models. It contains a 0.75-inch stainless NPT inlet and outlet connections and, as previously noted, connects the cold-water supply line to the tankless water heater.
- Cost benefits: Homeowners will reap cost savings through lower maintenance costs and a reduced need to periodically descale their Noritz tankless water heaters — even in locales with seriously hard water. The manufacturer’s suggested retail price for the updated Scale Shield is $178.50.
