The Scalemaster Magnetic Scale Inhibitor “Gold” Metal Body 22 mm CxC is a passive water treatment device designed to help protect central heating systems from scale build-up and corrosion. It fits directly onto 22 mm pipework and uses powerful magnetic and electrolytic action to capture and hold ferrous particles while inhibiting limescale formation, helping maintain efficient heat transfer and smoother system operation.
Function & Purpose
This scale inhibitor clamps onto the flow or return pipe, typically near the boiler, pump, or radiator feed. Its strong magnetic field attracts and retains ferrous sludge particles (such as rust) that circulate in the system, reducing the amount of debris that can settle in heat exchangers, radiator cores, and pipe bends. The electrolytic action also makes it harder for mineral scale to form on critical surfaces. The result can be improved water flow, reduced noise, fewer cold spots on radiators, and enhanced boiler efficiency.
Compatibility
The unit is sized for 22 mm central heating pipework with a coupler-to-coupler (CxC) fitting format, meaning it connects inline with existing pipework using standard 22 mm couplers. It is suitable for most domestic systems using this pipe diameter and fits both flow and return runs.
Design & Build Quality
The “Gold” metal body designation typically indicates a higher-performance model within the Scalemaster range. The robust metal housing provides durability and enhanced magnetic performance, while still requiring no electrical power or moving parts. Installation is straightforward: it is placed over the pipe and secured with couplers, and once fitted it works continuously without maintenance.
Key Benefits
This magnetic scale inhibitor helps reduce the circulation of ferrous sludge and inhibits scale formation without chemicals or power. It supports improved circulation, quieter operation, and better heat transfer by helping keep pipes and heat exchangers clearer of deposits. Users often find that boiler efficiency and radiator performance are maintained more consistently over time.
Ideal Applications
The Scalemaster Magnetic Scale Inhibitor 22 mm Gold Metal Body is ideal for domestic central heating systems with 22 mm pipework that are prone to sludge or scale issues. It’s particularly useful in older systems or systems where signs of debris-related inefficiency (such as cold spots, noise, or reduced heat output) are present. Fitting this device alongside proper water conditioning and magnetic filtration can help improve long-term system reliability and energy performance.
