Well it sort of worked

And for anyone who cannot see it's a magnetic cleaner so full of the
crud that it has collected that it has split open.

I'm somewhat perplexed by that. The only one I have ever opened up has a
magnetic stick enclosed in plastic, and the central heating water swirls
round the outside of the magnet. Just like that one in the photo, except
that the plastic protecting the magnet on mine had not split open.

Pin-prick hole in the plastic, letting water into the magnet which has
rusted and expanded, splitting the rest of the plastic open?

Also perplexed. It suggests that whatever was attracted to the magnet
has subsequently swelled. I can only think that initially it collected
a lot of iron swarf, filings or whatever, that subsequently oxidised,
with the resulting increase in volume.



TBH I have not had a lot to do with them.

I was actually at the job sorting out the outside lights that were
tripping and found this

in the garage and the plumber forwarded me the other photo.

I just thought it would make a change from Brexit posts.

Which was my point. They are not really very good, and of course they rely
on the crud being able to be electrostatically charged or magnetised to
work. Stuff which has neigher quality will just go straight on.

No the ones that work best use electromagnets and high voltages. But as has
been said before this is only part of the story.

The argument might run that magnetic and the like is the most damaging
material?

Can't see the harm in fitting one, especially in older systems. So long
as they're checked/cleaned once in while.

It still managed to collect a fair bit of ****e:-)

All systems will become old and start shedding rust particles which
could block the heat exchange, especially on a modern system.

They can catch a surprising amount of (magnetic) material which could
otherwise start blocking narrow channels.

The advantage is that they can be easily serviced to remove the crud.

They don't just collect magnetic crud, they are also vortex separators
and will collect other crud if its heavy enough and the flow is slow enough.

Depends, we had skirting board radiators that were just copper pipe
and aluminium fins in one house I lived in.

I fitted those in an extension I built in 1972.

The crud is iron oxide from radiators. It is magnetic.
If you have an aluminium alloy boiler heat exchanger, it's vital to keep it out.

Slightly OT, but I thought it was possible use a Magnaclean (or similar)
to put inhibitor into a system?

I can't find any youtube videos of anyone doing this.

Referring to the generic magnetic filters rather than any one
manufacturer....
Some models have a drain valve allowing you to empty the container which
then you can refill with any CH chemical. Other models don't have this
drain valve but you can syphon the water from the filter container. The
latter models tend to be shorter in length for fitting in smaller spaces.
The CH chemicals will then get circulated around the system when you
re-assemble the filter, release the isolating valves and run the CH
system as normal.

I understand that is the principle, but surprised it's little advertised
for the DIYer.

You can also get inhibitor concentrate that makes dosing that much easier.
