The Scalemaster Magnetic Scale Inhibitor “Gold” Metal Body 15 mm CxC is a passive water treatment device for central heating systems. It fits directly into 15 mm pipework and uses strong magnetic and electrolytic action to help reduce circulating ferrous sludge and inhibit limescale formation, supporting better system efficiency and reliability.

Function and Purpose

This scale inhibitor installs inline on the flow or return pipe of a heating system. Its powerful magnetic field captures and holds ferrous particles such as rust that are carried in the system water, helping prevent them from settling in heat exchangers, radiators, and pipe bends where they can cause blockages and reduced heat transfer. The electrolytic component helps discourage hard limescale deposits on internal surfaces. By reducing sludge and scale, the device can help improve water flow, reduce boiler noise, and maintain more consistent radiator temperatures.

Compatibility

The unit is sized for 15 mm central heating pipework with a coupler-to-coupler (CxC) format, meaning it connects inline using standard 15 mm couplers and is suitable for the smaller pipework typical of many domestic heating circuits. It can be used on either the flow or return side and complements other system protection measures such as inhibitors and magnetic filters.

Design & Build Quality

The “Gold” metal body indicates a higher-performance model within the Scalemaster range. The rugged metal housing offers durability and enhanced magnetic performance. The unit contains no moving parts and requires no electrical supply. Once installed, it operates continuously with minimal maintenance.

Key Benefits

This magnetic scale inhibitor helps reduce the amount of circulating ferrous sludge and inhibits scale formation naturally, without chemicals or external power. It supports better heat transfer, quieter operation, and smoother water circulation. Over time this can help maintain boiler and radiator efficiency, reduce maintenance issues tied to debris build-up, and extend system lifespan.

Ideal Applications

The Scalemaster Magnetic Scale Inhibitor 15 mm Gold Metal Body CxC is ideal for domestic central heating systems with 15 mm pipework where sludge, rust, or scale issues are of concern. It is particularly useful in older systems and installations showing signs of reduced heating performance due to debris or scale. Used alongside proper water treatment and filtration, it helps maintain system efficiency and reliability over the long term.
