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.
The Worcester Greenstar Mini System Filter 22mm (7733600266) provides compact, high-performance protection for your heating system by capturing magnetite and debris before they enter the boiler. Designed for maximum efficiency and easy installation, it helps improve system reliability, prolong boiler lifespan, and reduce maintenance costs—ideal for modern Worcester Bosch heating setups.
