    Protect Your Heating System from Magnetite

    Corrosion inside a heating system can create black iron oxide sludge known as magnetite.

    This debris travels around the pipework with the system water. As a result, it can collect inside pumps, valves and heat exchangers.

    A magnetic heating filter captures this contamination before it reaches critical components.

    Therefore, regular filtration can support cleaner system water and more reliable circulation.

    Powerful 11,000 Gauss Magnet

    The filter uses a high-strength 11,000 Gauss bi-directional magnet.

    This magnet attracts ferrous contamination from the circulating water. Meanwhile, the internal stainless steel filter captures non-magnetic particles.

    As a result, the filter provides two forms of debris removal within one compact unit.

    800-Micron Stainless Steel Filter

    Not all heating system debris is magnetic.

    Therefore, this model also includes an 800-micron stainless steel mesh filter.

    The mesh captures larger non-ferrous particles that the magnet cannot attract.

    This combination helps protect the wider heating system from different types of contamination.

    Suitable for Central Heating Systems

    The 28mm connection makes this filter suitable for many domestic heating installations.

    Typical applications include:

    • Gas boiler heating systems
    • Central heating systems
    • Radiator circuits
    • Underfloor heating systems
    • Compatible air source heat pump circuits
    • Heating system replacements
    • New heating installations
    • System upgrades

    Always confirm the required pipe size before installation.

    Suitable for Air Source Heat Pump Systems

    Modern heat pumps rely on consistent water circulation through the heating circuit.

    Therefore, keeping dirt and magnetite away from pumps and heat exchangers can form an important part of system protection.

    This filter can suit compatible air source heat pump heating circuits using 28mm pipework.

    It also works with water and water/glycol mixtures. This makes it useful where the system design includes glycol protection.

    Always follow the heat pump manufacturer’s water quality and filtration requirements.

    Ideal for Underfloor Heating

    Underfloor heating systems contain pumps, manifolds, valves and narrow waterways.

    Consequently, circulating contamination can affect system performance over time.

    A magnetic filter helps capture debris before it travels around the system.

    Therefore, it provides useful protection for both new and existing UFH installations.

    Compact and Flexible Installation

    The compact body suits installations where space is limited.

    In addition, the connection arrangement allows installers to position the filter in several orientations.

    This makes it useful beneath boilers and around compact plant areas.

    Always install the unit according to the supplied instructions.

    Easy Filter Servicing

    Heating filters need regular cleaning to remove captured debris.

    This model includes a large-bore drain plug. Therefore, engineers can empty contamination during routine servicing.

    The magnet also sits inside a protective sheath. Once removed, the collected magnetite can be cleaned away.

    As a result, servicing remains quick and straightforward.

    Water and Glycol Compatibility

    The filter works with both normal heating water and compatible water/glycol mixtures.

    This feature can prove particularly useful on suitable heat pump systems.

    However, always check the heating appliance manufacturer’s requirements before adding glycol.

    Why Use a Magnetic Heating Filter?

    A magnetic filter can help protect important heating components.

    Benefits include:

    • Captures magnetite
    • Filters non-magnetic debris
    • Helps protect circulation pumps
    • Helps protect heat exchangers
    • Supports cleaner system water
    • Easy routine servicing
    • Compact installation
    • Suitable for water/glycol systems
    • Suitable for boilers
    • Suitable for compatible heat pump systems
    • Suitable for underfloor heating

    Where Should a Magnetic Filter Be Installed?

    Installers commonly position magnetic filters on the heating system return.

    This allows the filter to capture debris before water returns to important equipment.

    However, every system design differs.

    Therefore, follow the boiler or heat pump manufacturer’s installation instructions.

    Also, keep the filter accessible for future cleaning.

    Magnetic Filter for Replacement and Servicing

    Magnetic filters need routine maintenance throughout the life of a heating system.

    They may also need replacement because of:

    • Leakage
    • Damaged connections
    • Cracked components
    • Failed seals
    • System alterations
    • Heating appliance replacement
    • Heat pump upgrades
    • Plant room refurbishment

    Always check the existing 28mm connections before ordering a replacement.
