The Combiphos 800g refill pack offers a reliable and cost-effective way to maintain limescale protection in domestic hot water systems. Designed for use with Combimate and Combiphos dosing units, it helps protect combi boilers, water heaters, and pipework from the damaging effects of scale.
Limescale commonly affects systems in hard water areas. Therefore, regular refilling with Combiphos helps maintain system efficiency and reduces maintenance costs over time.
What Is the Combiphos 800g Refill Pack?
The Combiphos 800g refill pack contains high-quality polyphosphate crystals that inhibit limescale formation. These crystals dissolve slowly into the water supply, coat internal surfaces, and prevent scale from forming.
The pack also includes a new O-ring seal. As a result, installers can achieve a secure and leak-free fit when replacing exhausted media.
How Combiphos Scale Inhibition Works
Combiphos doses small amounts of polyphosphate into the incoming water supply. When the water heats up, it becomes far less likely to deposit calcium carbonate. Consequently, scale build-up inside boilers and heat exchangers reduces significantly.
Unlike water softeners, Combiphos conditions minerals rather than removing them. This approach makes it suitable for potable water systems.
Key Benefits of the Combiphos 800g Refill Pack
Effective Limescale Prevention
Regular use of the Combiphos 800g refill pack protects boilers and heating components from scale damage. Therefore, it helps maintain system efficiency and can reduce energy consumption.
Compatible with Combimate Systems
The refill pack fits Combimate and Combiphos housings precisely. As a result, installers and homeowners can complete replacements quickly and easily.
Includes New O-Ring Seal
Each refill pack includes a new O-ring seal that creates a tight and secure fit. Consequently, it helps prevent leaks and supports long-term system reliability.
