Combimate - Limescale Prevention Device

Combimate is a user-friendly domestic limescale prevention device that uses Combiphos to deliver guaranteed prevention of limescale and soft water corrosion water control, with no moving parts.

Tried and tested – Combiphos is a polyphosphate compound specifically developed to provide the most effective limescale prevention in flow-through installations. Polyphosphate dosing has been safely used to treat water throughout the world for many years.

Note: Combiphos does not soften water and its effectiveness may be reduced in water heated to temperatures above 60 degrees, in water with carbonate hardness levels above 360 ppm or at pH levels below 6.5.

Combiphos is 100% food grade material approved by the FAO/WHO and compliant with the European normative standard BS EN 1208, that prevents scale build-up and soft water corrosion in combination boilers and other domestic hot water appliances.

Health and safety – Combiphos is tasteless and odourless and contains a polyphosphate compound which is classified by the WHO as a ‘food-grade’ additive. The quantity, size and hardness of the spheres control the amount of Combiphos released. Typically this is less than 3 ppm (parts per million) of phosphate in treated water and perfectly safe for human consumption.

There are two installations options when fitting Combimate: whole-house supply or single appliance protection.
