This deal is expired. Here are some options that might interest you:

May be a deal of limited interest, but as long as it does some of you a turn. Usually around £85-£90, and not so readily available at the lower price bracket. I've done plenty of searching to know. Ive got the bits, all I need is a plumber.

Good deal! Surprising how much carp these things catch.

HotUKDealSeeker24/01/2020 23:03

I do need one. But my pipes are all 15mm


15mm is usually around radiators. Boiler is likely to have 22mm...check it as this should go as close to the boiler as possible on return
I read these or at least the standard versions leak after a year...?

Sentinel and magnaclean seem to have better reviews

Have a look at all brass filters , spirotech , fernox etc all make them . Not as likely to leak as plastic . Not much more expensive.... £10-20

You can do a chemical clean of the system as well since you can pour stuff in them without emptying the system

i had the plastic one which leaked. engineer told me it was a common problem as plastic to metal pipes don't seal as well as metal to metal. the metal ones don't cost much more and last longer. so for the sake of £20 or so better to get the metal one

I think if you loosen all the crap in the system and have nothing like this filter to catch it then yes you will ruin your boiler...

Does it totally replace the liquid inhibitor or should be used both better?? Thanks

Depends, if you have an old boiler with self sealed leaks inside, ie you can see limes ale buildup on the outside of pop joints, then yeah possible the chemicals will clean away the seal and cause it to leak. Otherwise I’d ask how he thinks it’ll kill your boiler. If you do a proper power flush and isolate the boiler from it then it won’t collect any of the carp.

Only an issue with an aluminium HEX, and then only a problem if you don't manage to flush it all out as the acid will react with the aluminium to create Hydrogen in the circuit. You can (and should) test with litmus paper to chech the PH level once complete.

I was told the same. I told my plumber to fit magnetic filter that I supplied (magnaclean 2). After he fitted it, I used the chemical myself and flushed the system.
There are many online guides to help how to chemical clean. And I am not talking about power flush, which require additional equipment.

Different purposes, inhibitor inhibits oxygen hence limits or stops radiator internal corrosion...if such corrosion occurs, magnetic filter catches the debris before it gets to the boiler and damages heat exchanger or valves/pumps etc

No. Should use both. One will minimise corrosion the other will catch already loose and future corroded bits.

Mine started leaking about 2 years after it was installed, just purchased a new seal kit for about £3 and that did the trick.

Definitely, it must have isolation valves, top and bottom in order for the filter to be cleaned and serviced. I have a generic filternand they all seem to be basically the same. Turn the boiler off, isolate the water supply via the valves on the unit, undo the cap, drain down the water inside replace with your cleaner, inhibitor etc. Refer to the instruction manual that came with the unit for exact details. The only problem I had when adding one chemical was I needed to do it in two stages due to the amount that needed to be added, but otherwise dead easy to do.

yes it has valves top and bottom, but then its full of water which would be a pain to remove and it would then still not hold enough liquid to be of any I thought
Max_Hardwick24/01/2020 22:58

Brilliant things and dead easy to fit. I think I'm right in saying that pretty much all boiler manufacturers insist on you having one of these fitted at the time of installing a new boiler in order to meet the requirements of their guarantee. They normally state it has to be a certain make rather than one of your choosing. They've probably done a deal with them!

You can remove the water, pour half the amount, close filter, open valves, let it run for a bit then repeat with the second half. Then I think it needs to run for some time before draining system to take out the mucky water with the chemicals, but this will be in the products directions for use

Most heat pump manufacturers have this as a standard component inside of the pump to protect the components and plate exchanger.
I guess it's a natural development as it saves space and only one unit to fit?

I'm a novice as far as these are concerned. I hadn't noticed any bad reviews though, not to say there won't be if I dig deeper. Do the others come as compact too? I can't see info on dimensions of this. My previous boiler never had one fitted,cowboy job anyway, which is why my boiler is wrecked now, and a radiator too.😡

Did he put inhibitor in? Lack of it sounds like more of a cause than lack of mag filter...

Vortex 300 from Sentinel is decent size...also should be better at taking non ferrous debris out...59.99 on amazon

One more question to the experts:
Using lets say double amount of inhibitor (sentinel x100) on a certain given amount of water in the radiators, could actually damage the system? or it is beneficial or does not make any difference??
Thanks

Always follow manufacturer's instructions. Nobody can confirm adding more will do any good until research can confirm it and also if it was beneficial then the manufacturers would have made the concentration stronger in the first place.
Nevertheless I do not think adding double will harm the system - it is just that it may not be beneficial and would be a waste of money and resource.

They do different things but both help your system, a inhibitor stops the water in your system corroding the steel parts ( Radiators ) it also does a few other things, but rust prevention being the main feature.

A magnetic filter like this catches the sludge in your system and prevents it from entering your boiler, the sludge is normally caused by the rusting of steel parts.

it’s best to have both, but clean / power flush your system before adding the filter and inhibitor so they can do there job properly.

To be honest if installation was done well with no leaks -> no need to add water to raise pressure, the system was never drained and proper amount of quality inhibitor was added during installation, I wouldn't dread 6 years...on the other hand if any of the above was not done and/or the radiators are much older than the boiler, yes you should add one...
