Why we love it
  • Reduces heating system sludge.
  • Saves up to 6% energy.
  • Durable, high-quality materials.
Main Highlights
  • WHY NEED IT?: As water passes through the metal pipes of your boiler, rust can form. Combine this rust with other dirt and debris, it eventually builds into a mud-like substance, otherwise known as ‘sludge’. If this sludge isn’t removed it can have a real impact on the day-to-day use of your heating system. Reducing your heating system’s lifespan.
  • EFFICIENT: Our Magnetic Water Filter will help reduce the build-up of iron, nickel, and cobalt particles in your system and saves up to 6% energy per annum. This filter can be easily drained and is easy to clean.
  • EASY TO INSTALL: Locate a suitable site for the filter to allow access and servicing, release and drain the heating system pressure before trying to make space for the filter. Cut the Pipe, introduce the diverter and Fit the filter body to the diverter and hand tighten the locking collar. Open the isolation valves and turn on the heating system and you’re good to go, for further instructions read the provided instruction manual.
  • QUALITY: It is made of PA66 3(0% glass fibre) and premium quality brass, which makes it particularly durable, and it is entirely compatible with replacement spare parts.
