Protection against limescale

Protection against limescale in household water.

Limescale is a solid chemical compound, or coating, that forms on the inner walls of pipes or various household appliances and causes a range of problems. In the home, limescale is most often based on calcium carbonate.

Limescale forms due to a shift in the balance between carbonic-acid and calcium-hydroxide ions as the temperature changes. Limescale clogs electrical appliances, reduces the efficiency of the heating system, fouls valves and causes an unpleasant taste in the water. A range of reliable products and solutions are available for removing limescale.

Frequently asked questions

• How does Siliphos-based limescale protection work? An in-line system doses a microscopic amount of polyphosphate (Siliphos) into the water, which coats the calcium crystals and prevents them from settling on pipe walls and in appliances.
• How often does the Siliphos cartridge need to be topped up? This depends on the flow rate and water hardness, typically once every few months up to a year; the system is refilled by replacing the cartridge or the bulk media.
• Is Siliphos also suitable for drinking water systems? Yes, it is a food-grade certified substance intended for treating both drinking and utility water.
• What is the difference between Siliphos and magnetic water treatment? Siliphos works chemically by dosing the product directly into the water, while magnetic treatment works without any consumable material, on a physical principle.
