Good price for what I think a great upgrade to your heating system

if you have one, just clean it , no need to replace with new one every year

This looks better to me.... has filter too as well as magnet... Zeebee £34.99

What's "powerful brass"

If you put few magnetic limescale removers on your heating system pipes as well which will reduce limescale build up and fewer breakdowns. Anyone has used magnetic limescale removers ?

Cost me £300 to sort a leak caused by one of these. The plumber said they are useless and not worth replacing. Just my 2p.

Thanks didn’t know they could be cleaned. Will give it a go

Make sure you turn off the valves above and below it first. Watch a video on u tube about it

Looks suspiciously similar to the older style Trappex one's I've fitted a few of. Decent quality if they are.

It does indeed look like the centramag.

Cant really go wrong at this price. At the end of the day its a magnet in a plastic tub. If installed right it’ll be fine.

Says who...





Also... it’s ‘you’re’ - not ‘your’





Plumbers and property developers can spell too, you know.


For clarity - your plumber said these are crap and they’re not worth having or replacing with another magnaclean ... that s/he was more comfortable with..?

I'm curious as to how a leak by one of these cost £300 to fix? l'm a plumber/CH engineer and if a systems being worked on i'd always recommend to fit a magnet filter. l use a Kamco magnet filter on power flushes and it can be a shock what comes out of some systems.
PS. Saw a Fernox TF1 Omega Filter at the PHEX show which looks a good peice of kit but twice this price

All gone

I’m a plumber absolutely dreadful piece of kit

The £300 bill might have been because the leaking unit was an original Magnaclean with red valves. The red valves are prone to leak and some plumbers remove the whole unit and replace it with a different make. What they should do instead is replace the red valves with the improved black valves. If they ask nicely, Magnaclean might even supply the black valves free of charge.

Does this help prevent corrosion in boilers? I've recently been told by my plumber that the boiler has signs of corrosion. I read up and saw that that was a result of oxygen in the water.

Just ordered one, these stop sludge build up in radiators and boilers , if you put them on an existing system then you need to clean the filter daily until the systems clean , highly recommended .

No. They remove sludge from your system which is magnetic as a result of corrosion (Magnetite), which sits in your system affects heat transfer etc. If you can, get your system Powerflushed, about £150, pre-treat system with a cleaner, Powerflush, then dose your system with anti-corrosion treatment. You can Powerflush your system yourself if you are reasonably competent, hire a unit from Jewson, weekend rates. Not the best time of year to do it (winter). Ideally you connect it by removing the system pump, installing the unit across that point and follow instructions. You can connect at a radiator if more convenient, probably is for most people, best to connect where you can run a hose to waste. Instructions provided.

Yes... essentially.

Oxygen in the water..? Not sure what he means by that.




As your heating system ages you may get sludge in it from corrosion ... essentially the inside of your radiators rusting - plus other factors.





One of these will be fitted to the return pipe to your boiler on the heating side (usually return) - its magnet then catches any magnetic particles that pass through it. Meaning those particles dont:





A) pass through the thin channels of your heat exchanger, potentially clogging it (can be very expensive and in some cases mean a new boiler...)





B) don’t collect within your heating circuit and again cause blockages... which again can be expensive to resolve (power flushing etc etc)





So if you can get one then do so. Fitting cost... probably £80-£100 depending on its siting and ease of access/whether the person is a tool or not.





Some manufacturers insist on one to honour a warranty.

Thank you, I will look into this when it is time to get a new boiler

Boiler in loft, this leaked through light fitting ruining ceiling. I'm not a plumber but apparently they aren't good. Sludge from copper, zinc or aluminium isn't ferrous and won't be caught by a magnet. Any good system should have inhibitor put in which should do a good enough job without needing one of these apparently!

A poorly fitted or faulty magnetic filtering device will cause a leak. A well fitted and resell built one will not. Many boiler manufacturers will not honour warranty claims if a recognised filter isn’t fitted.

Your story while I don’t doubt true, is out of context. Sounds like your filter was faulty, not that the concept is a waste of time.

The idea that boiler manufacturers wont honour warranties without a filter is rubbish. On installation a system has to be cleaned in accordance with BS 7593, that is all. If a manufacturer is trying to wriggle out of the warranty, it's because a crap installer hasn't bothered cleaning the system, and instead thinks the filter will do that job for him, or has neglected fitting one completely.

Worcester might add an extra years warranty for their overpriced (rebadged Magnaclean) filter (£50 more than said filter), that's the closest there is to insisting on one.

Any decent filter will also have a particulate filter to trap non ferrous sludge.

I think the filter was faulty, I asked the plumber if it was worth replacing and he said not to bother, so I didnt.

Me too, but £99 is enough and I would have expected that they clean this as well. Next year (3rd year) it needs an extended service....

Old boiler was about 30 years old and no problems at all (except for the pilot light thermostat which I changed every few years).

Ferroli (yes, i know..). Wouldn’t honour the warranty in one of my first properties as the HE was blocked - this was considered to not be a fault with the boiler... but with the installation not having a magnaclean... which in-turn caused the HE issue.

They then went on to say that the repair would not be covered, despite still being under warranty - as the boiler had only failed due to improper maintenance - and not malfunction. Serviced every year. Failed in year 3. Assumed correctly flushed prior to installation, but we both know that ‘doesn’t always’ (read rarely) happen.

I’ve done work with gas engineers prior to ACS and haven’t seen anything other than a drain down and inhibator on installs - wrong, but i dare say common practice.

Genuinely - how many times have you seen a tf1 or something chucked in and a ‘that’ll sort it’ - attitude?

Just sayin...

So you joined HUKD just to say that? even if you fit these you still need to treat your systems.
