VANCOCO Magnetic Boiler Filter 22mm with 360 Fully Rotatable Installation, Includes Isolating Valves, Magnetic Filter for Central Heating System, 9000 Gauss

VANCOCO
Why we love it
  • Premium brass, highly durable.
  • Extends boiler's lifetime significantly.
  • Saves maintenance costs effectively.
Main Highlights
  • PREMIUM QUALITY - VANCOCO magnetic boiler filters are made of excellent brass and are very durable. Effectively removes iron, nickel and cobalt particles from water.Intensity up to 9000 Gauss
  • EXTENDED BOILER LIFETIME - Even if you spend a long time researching the best boiler, they will still rust and corrode, and a magnetic boiler filters can effectively help solve this problem.Capturing rust and other debris that may form over time will extend the life of your system
  • SAVES MAINTENANCE COST - The removal of any contaminants in the system will enable your system to run smoother and more efficiently, which will also improve fuel efficiency and save maintenance cost in the long-run
  • VANCOCO MAGNETIC BOILER FILTERS - A magnetic filter will be installed along with the new boiler. You can reduce the risk of the following problems.1.When your energy bills go up, but your home gets colder.2.Lots of noise coming from the boiler/radiators when the central heating is on.3.Cloudy or dirty water coming from the taps. Enjoy a clean heating system free of sludge and iron oxide deposits
  • EASY TO INSTALL - Magnetic boiler filters feature 360 Fully Rotatable Installation, enabling placement in practically any location to fit any boiler, including tight spaces like underneath the unit. This design flexibility ensures compatibility with compact installations where space is limited. For optimal performance, we recommend positioning the filter between the last radiator and the boiler, allowing it to capture debris before it re-enters the system. The 360-degree rotational capability ensures seamless alignment with existing pipework, even in constrained environments
