Yes
I have a plumber coming round this evening to give me a price for a new combi boiler. I have heard that he recommends having a magnetic water filter fitted. Does anyone have one and what are your thoughts?
 
Dont need them up here, if down south with hard water, then a water softener and magnetic filter will be of use, but round Manchester we get luuuuverley soft water from the Lake District.
No limescale = virtually no corrosion in the rads = no rust that needs removing!

Any good CH engineer will put a corrosion inhibitor in the system water, so a filter is suplus to requirements.

Ignore my reply if already read, sorry I misunderstood what you said.

It filters out bits of metal from the system, I was amazed just how much much it takes out of the system and I guess it helps to remove one of the causes of small radiator build-ups that cause cold spots. Having seen what it takes out my feeling is that it has a beneficial effect on the system.

Thanks Gramps, opinion noted. Anyone else got any comments before the plumber comes?
 
beneficial to the plumber, who by the will offer to maintain it every three months or so, also depends if its an old system if so then a flush out and inhibitor will be just as good
 
A definate benefit.
Whereas the system should be flushed out prior to the new boiler being put into service there will always be bits left floating round the system, it needs to be cleaned out at the same time as your annual boiler service.
Just as a side note, all I do is boiler breakdowns and leaks for insurance companies, always take a sample of water from the system and if it shows the system is dirty/sludgey their claim becomes invalid due to not maintaining the system to a good standard, the same is done by manufacturers when called to a warranty claim.
 
I fitted one at my girlfriend’s house when I fitted a new boiler for her it’s a must for an existing system,

I take it he will not flush the old system as sometimes this can cause more problems so he will most likely drain it down and refill when the boiler is fitted.

When he fills up the system again it will disturb all the sediment and send it around the system and back to your new boiler, fitting a magna clean will clean all the sludge out.

Check the you tube link it will give you an idea
 
Just another note...plumbers don't install boilers, they put in sinks, basins and baths ;)
Make sure you check his gas safe card to ensure he has the relevant qualifications to install boilers... They are listed on the back of the card.

No problem! :thumbs:

I got my info from my neighbor and friend (he looks after my CH, and installed it) 32 years in the CH buisness, Gas Safe certified and as honest a bloke I have ever met.
 
Very easy to clean the filter yourself as well and it does work.

I always thought they were not really necesary until I bought a house with one fitted, and the cack they get out is quite suprising.
Also you may find that part of the warranty on the new boiler requires that the system is power flushed aswell.
 
My brother's a plumber and fitted a new combi boiler for me in March, he wouldn't fit it until he'd completely flushed the system and fitted one of these filters.

The water's extremely hard here and he always recommends fitting these filters.

Now where I'm concerned I bought the filter myself and my brother didn't charge me for fitting it or the boiler so it there was certainly no benefit in him recommending one if they weren't worthwhile ;)
 
Well as stated above, our water is very soft here and saves a fortune on soap and washing powder!
 
Hard water or limescale is not relevant when talking about these particular types of filter. These filters help prevent sludge and magnetite affecting the boiler and pump etc. and yes they are worth it. Some are better than others, but they all work.
 
We had our boiler replaced last year when it packed up. The chap did a power flush and added an inhibitor. I did ask about a filter but his response was that it was unnecessary and that the warranty was good as long as the boiler was serviced. He did say we could have it fitted if we wanted to do.

They are without doubt of great benefit to existing and new heating systems,fitted in the return pipe to the boiler it will help protect the boiler and system. Fitted post flush/inhibit they are worth every penny. Some are better than others,Magnaclean were one of the earlier models,at the time they came out most of us installers viewed them as the best thing since sliced bread, however there are now other,better models out there from numerous manufacturers. There is also talk of them being introduced into building regs for replacement and new systems??
