Treating existing limescale and reducing new build-up

The household challenge

Limescale tends to appear on

Inside heating systems

Impairing boiler efficiency and driving up energy consumption.

Showerheads and taps

Clogged showerheads and reduced water flow.

Kitchen and bathroom surfaces

Stubborn stains on glass, tiles and sinks.

While HydroFLOW doesn’t remove limescale from the water or affect its natural benefits, it addresses mineral build-up in pipework and appliances — all without adding salts or chemicals to the water. This lets water flow more efficiently and helps reduce many of the common effects of hard water at home and in everyday life.

Why combine two treatment points — not just one

Full protection starts at two points, not one

Pearl Plus is an excellent solution for protecting your entire home water system, thanks to its strong signal that propagates over long distances — especially suited to the home’s main inlet. In Israel, hot water tends to be harder and more saline — so we recommend combining it with a Pearl unit targeted on the cold-water line to the water heater, for focused reinforcement at exactly the most sensitive point.

At the home’s main inlet

Pearl Plus

A strong signal that propagates over long distances — general protection for the entire home water system.

On the cold-water line to the heater

Pearl

Additional targeted protection, at exactly the point where limescale and hot-water hardness do the most damage.

This combination is especially recommended for larger homes or hard, saline tap water — broad and targeted protection together. In the shop you’ll find pricing for each unit separately, as well as a special price for buying both units together.
