The Scalemaster Electrolytic 28 mm Gold is a magnetic and electrolytic scale and sludge reducer designed for central heating systems. It fits around 28 mm pipework and uses combined magnetic and electrolytic action to help remove metallic sludge and reduce limescale build-up, improving heat transfer, circulation, and system efficiency.

Function & Purpose

This device attaches externally around the 28 mm flow or return pipe in a heating system. It generates a strong magnetic field and electrolytic effect that attracts and holds ferrous particles (sludge) and inhibits the formation of limescale on heat exchangers and pipe surfaces. By capturing debris that would otherwise circulate and settle in radiators and boiler heat exchanger surfaces, the Scalemaster Electrolytic Gold helps maintain cleaner water, better heat transfer, quieter operation, and reduced risk of blockages or early failure.

Compatibility

The unit is sized for 28 mm central heating pipework, making it suitable for many domestic and light commercial heating systems that use this pipe diameter. It is typically installed on the flow or return near the boiler, pump, or key radiator circuit entry points, and works alongside standard system inhibitors and servicing practices.

Design & Build Quality

The Scalemaster Electrolytic Gold features a robust housing with an internal system engineered to produce both magnetic and electrolytic action. The “Gold” designation often indicates a higher strength or performance level within the Scalemaster range, intended for larger systems or those with significant sludge/scale issues. It requires no electrical power, moving parts, or regular maintenance, and it passes water through normally while managing contaminants externally.

Ideal Applications

This product is ideal for heating engineers and homeowners seeking to improve central heating performance by reducing sludge and scale build-up in systems with 28 mm pipework. It is particularly useful in systems showing signs of poor circulation, cold radiator spots, noisy operation, or reduced boiler efficiency due to debris accumulation. The Scalemaster Electrolytic 28 mm Gold supports longer equipment life, improved energy efficiency, and fewer service issues when used as part of a proactive system care regime.
