"Installed with my new boiler 3 years ago. Even though my system was completely power flushed at the time, this still removed lots of the black deposits. Easy to remove and clean, which I do 6 months after the boiler service, when my boiler man also does it. The black sludge was a problem over the years, restricting flows, and gumming up thermostatic valves, but not now. Fully recommend with no negatives."
"This product is essential on any central heating system to avoid sludge buildup. With this unit you will extend the life of your boiler and hopefully eliminate costly boiler repairs that will not be covered by insurance or manufacturers warranty.
Do not install a new boiler on an existing central heating system without this unit.
The new units now come with ADEY MagnaClean Professional Central Heating Sheath Upgrade Kit (Product Code: 54558) therefore do not order this upgrade as its not required.
Main disadvantage is the price. Very costly product for a plastic tube with a magnet."
"I have serviced the MagnaClean once since its been installed and its already started to collect lots of black particles. It was really easy to install and is a great product. I will definitely be recommending to others.
I've read it can save me money on my heating bills, I'll be sure to keep an eye on this. Only time will tell."
"I have used these filters in the past and they do what they claim. My only gripe is how do you empty it so you can re dose the system. If you use the Fernox TF1 it is more flexible for installation. It can be fitted on vertical or hosizental pipework. You can either isolate it and drain the filter through the purpose made drain valve for cleaning and redosing or drain the system through it. Easy as that. Never had any leakage from lid or seals. A1 piece of kit."
"Have been fitting these filters for a while now and have nothing but good results.. Even with a powerflush and inhibitor used, the yearly service of the Magnaclean shows Black oxide sludge caught out of the system.. With a new boiler installation this item is a no brainer.."
"I can only agree with PigletJohn's review although some of this could have been down to the installers (external contractors for that ex-national monopoly).
After a few years being installed, we found water dripping through the ceiling. This was due to water pouring out from under the cap. The circulation pump was off at the time and it is a vented system so there shouldn't have been a large pressure.
Shutting off the isolation valves caused them to leak, not high quality.
When I came to try to uncrew the cap, even after releasing the bleed valve, it required a huge force, perhaps due to it's initial installation but more likely due to the leaked water.
On the positive side, it did contain some black sludge and metal flakes that would otherwise have ended up in the boiler."
"I got one of these, it was the first popular mass-market device for taking particles out of the circulating water (you ought to use a cleaning chemical first to loosen the old sludge and flush it out). It was spectacular at collecting black sludge. However the plastic screw-on cap leaks now it is worn, and so do the isolating valves, which are very poor quality, at their spindles. You can get much better quality for the same price. I would not buy Adey again."
