Enhance your plumbing system's efficiency with the CalMag Magnetic HF1 Filter Pack. This pack includes a scale inhibitor and sludge flux remover, effectively improving water quality and prolonging appliance lifespan.

The Fernox Electrolytic Scale Reducer 22mm Compression is an in-line water treatment device designed to help prevent the build-up of limescale throughout the home.

Using electrolytic principles, it alters the structure of hardness salts in the water, encouraging them to coagulate and helping reduce the formation of scale in appliances and hot water systems. It provides whole-house protection against limescale and is effective immediately after installation.

The scale reducer is maintenance-free and can be installed on horizontal or vertical pipework using 22mm compression fittings. Under average domestic water usage, it can remain effective for up to 10 years, depending on water usage levels.

The unit is made from forged, nickel-plated brass and is WRAS approved. It is pressure rated to 10 bar at 20°C and is designed for cold feed applications.

The Wyndam Branded 22mm Electrolytic Water Conditioner is designed to reduce limescale build-up in domestic water systems, protecting plumbing and appliances. Ideal for 22mm pipework, it prevents scale formation by altering the properties of hard water minerals, ensuring longer-lasting efficiency for your water system.

The Wyndam Branded 22mm Heating Filter is designed to protect your central heating system by capturing debris, sludge, and other contaminants. Suitable for 22mm pipework, this heating filter improves system efficiency, prevents blockages, and extends the lifespan of your boiler and radiators.

Fernox Antifreeze Protector Alphi-11 is a combined antifreeze and corrosion inhibitor designed to protect domestic central heating systems against freezing, internal corrosion and limescale formation.

Alphi-11 contains mono-propylene glycol and provides frost protection while helping to maintain the long-term efficiency and lifespan of the heating system. It is suitable for use with all common heating system metals and materials, including aluminium.

A minimum in-use concentration of 25% is recommended to provide adequate corrosion protection. At this concentration, Alphi-11 provides frost protection down to -11°C. Increasing the concentration to 40% provides protection down to -22°C.

Alphi-11 is suitable for heating and chilled-water systems and is compatible with other Fernox products. For new or untreated systems, Fernox recommends thoroughly cleaning and flushing the system with Fernox Cleaner F3 before adding Alphi-11.

CalMag 22mm Compression Magnetic Scale Inhibitor for preventing limescale formation in cold water lines. Supplied with 22mm compression fittings and adaptable for push-fit connections, it provides whole-house scale protection without chemicals or additives. Maintenance-free and requiring no earth bonding, with a maximum working pressure of 12 bar and temperature of 80°C.

Delivery: Tracked 48 £2.99 (2–3 working days) or Tracked 24 £4.00 (1–2 working days). Free collection from our Wellingborough branch.

The Fernox TF1 Sigma UB Filter is a compact 22mm magnetic heating system filter designed for installation underneath boilers and in restricted spaces where a conventional in-line filter may not be suitable.

The under-boiler design features a durable glass-reinforced engineering polymer filter body and a forged brass manifold, providing a robust solution for protecting heating systems from circulating corrosion debris, including magnetite.

A powerful neodymium magnet captures ferrous contaminants from the system water, while the engineered flow path is designed to provide high collection efficiency without blocking or restricting flow. The integrated three-way valve allows the filter to be isolated and cleaned through the drain point without dismantling the filter.

Designed to be installed horizontally on the return to the boiler, the TF1 Sigma UB is particularly useful where space is limited or pipework is concealed. Separate flexible or corrugated pipes and/or adapters may be required for some installations and are not supplied.
