Great Product _ Great Value
Really good product. I swapped out a a Fernox TF1 which is 3 times the price of this one. Same fittings, insert size and it was an easy fit/ replacement. A*

Works well and simple to install and use
Good quality parts. Straightforward to fit and maintain with no leaks. The two isolation valves are easy to operate for cleaning out. Heavy particles collected by the filter can be emptied out first. Magnetic particles can be released by withdrawing the strong magnet. An impressive amount of crud was collected in a bucket after only a few days.

Good boiler mag.
This boiler mag is incredibly competitively price compared to market leading brands. That said that saving does not appear to have came at the expense of quality. The unit it's self feels good quality and nice and durable. Very simple to fit on the return pipework with basic plumbing knowledge and tools. The valves were a little stiff initially but I presume that's a result of it sat in a warehouse for a period of time before I purchased it. I would question the accuracy of the integrated temperature gauge as that didn't move when I tested the heating on a new boiler install however my intended use is for the mag filter its self rather than a temperature gauge. Happy to recommend.

easy to fit and makes adding inhibitor etc to your system very easy.
fitted to a new heating system and installation was fine, makes it easy to add cleaner or inhibitor to your system.

Good price. Good construction
Simple to install. Replaced another brand filter owing to the detachable magnet being lost? This one has all the features I needed, isolation for maintenance without having to drain the entire system. A little plumbers silicone grease is advisable on the moving parts to help with future maintenance.
