Hi

My mum has had a recommendation from a British Gas engineer to fit a
Magna Booster to her central heating - which apparently removes lime
scale from your central heating system and 'stops it from blocking
up'. The charge for this is £250 parts and labour. She lives in SW
London - the water is quite hard.

Is this Magna booster a good idea - or a useless gimmick? My mum has a
Potterton conventional gas bolier fitted about four years ago and is
on a service contract with BG.

Thanks for you advice.

If she believes in magic and is trying to get rid of excess money, then
yes

Conventional as opposed to condensing ?

That would most likely be illegal

and is
on a service contract with BG.

There's a mistake for a start

Useless gimmick IMO. Dr Drivel will no doubt differ, but he's a nutter
(really).

If you do decide to go ahead, get quotes from local plumbers. Will be a
LOT cheaper than BG, and the workmanship will be better.

Example: I asked BG to quote for a boiler replacement a couple of years
ago. I also asked for a quote from a local, trusted plumber/heating
engineer. The local chap's quote actually included some additional bits,
as it turned out.

BG (with £600 discount included) - about £3250.
Local man - £1900.

And that was with a better boiler as well.

they have a nasty habit of claiming the boiler needs replacing because

Utter bull****. With a conventional boiler and indeed with a
condensing one the central heating water just circulates. The system
should have inhibitor(*) in this water to prevent corrosion. Even in
a very hard water area the amount of lime bought in for filling the
system is not remotely anywhere near being problem.

The only problem is if fresh water has to be introduced regulary to
counter leaks but even then the problem will be mainly from the
oxgyen in the fresh water leading to increased corrosion not any
lime.

The charge for this is £250 parts and labour. She lives in SW London -

Tell 'em to go take a running jump.

(*) But as this system is under a BG "service" contract I wouldn't
like to be on that.

From the Daily Telegraph "However, recent industrial unrest has led to
many engineers posting their experiences on internet forums, including
the “Gas Leak” forum on the GMB Union website, and on the Telegraph
website [in response to Harry Wallop’s report of March 23]. They claim
British Gas management will not admit that its engineers are given
commission for selling, but prefers to describe the process as
“earning time bonuses” for “giving best advice”. If an engineer “gives
best advice” that a customer should buy a new boiler, for example, he
is allegedly rewarded with a time bonus equivalent to £12, and is
given a management target to give this kind of advice at least 24
times a year. If he “gives best advice” that a customer needs a
powerflush, or to buy a magnaclean filter or carbon monoxide detector,
the alleged time bonus is equivalent to £9 or £10 each time."

Avoid BG engineers like the plague.

You really do not know what you are talking about and should not give advice

magnetite and other solids that would have blocked the heat exchanger. The
solids bake onto the inside on the small tubed heat exchanger. Most use the

Could that have been "Magnaclean" rather than booster? If so, it only
really seems to treat a symptom rather than a cause of a problem anyway.

It protects the heat exchanger as it is on the return. It also prevents
radiators sludging up.

Seems kind of pointless - the water in a heating system is stagnant - once
all the scale has precipitated out there is no more to come.

The inhibitor wears off and water is reintroduced at various time. If using
a vented F&E tank, fresh water is introduced regularly,.

Scale in hard water areas affects the domestic hot water side of the
system where the supply of water is fresh and ever changing. These devices
could only collect scale on the sealed primary side of the system.

They collect magnetite from the corrosion process. Sludge can ruin a
system. many system are running very inefficiently because the rads are
full of sludge. The sludge collects in the rads and the heat exchanger.

There is some argument for having a particulate trap on the return to the
boiler to prevent any debris reaching it (and the magnabooster appears to
include one of these - although at many times the price of a basic
strainer), but the primary requirement is to prevent the generation of
corrosion products in the first place by proper flushing and cleaning
followed by regular maintenance with inhibitor. Letting the system rust
and mopping up the result seems like its solving the wrong problem.

Basic strainers are not good enough. The Magna Booster collects the harmful
magentite and solids in the system. Most systems are not flushed well
enough on a boiler change and sludge ends up in the new boiler's heat
exchanger. They are "essential on a boiler change using existing rads.

I have seen sludge and solids collect in a Magna Booster filter after a
year, in a flushed new system with the correct amount of inhibitor.

They cost around £110 to £120.they are best filters. They can also be
emptied by the homeowner, being so simple and well designed. £250 to fit
sounds OK.

Would you buy a £50,000 car and put cheap £7 a can oil in it? You buy oil

We live on the South Downs. The water is harder than in London. THe CH
system has been in place for 25 years with only a change in boiler to
get a more modern unit a few years ago. There's no sludge in the pipes
or radiators. I know because runs of pipework were taken to pieces for
checking when the new boiler was installed.

As others have said, the water in the CH system does not get changed,
hence there's no problem with limescale or sludge.

If you're de-sludging annually, your inhibition needs looking at!

You are right. But it will catch the stuff if the inhibitor breaks down or
neglected. It also catches solids on commissioning.

Many installers use them on boiler changes to avoid the expensive poweflush.
They flush through with fresh water, and run the pump, then after 1/2 hour
empty, and then another 1/2 hour. They do this as they say do the electric
and tidy up, some plastering or whatever. Many put two does of X-100 in it
and of he homeowner is competent enough tell them to empty it every moth
until clean and top up to 1 bar. They hate call-backs.

Does an inhibited system generate enough
sludge to warrant a magnetic trap?

I theory no. In practice yes. Few are redosed at the correct time. On
boiler changes, which is most of the work these days, they are essential to
catch the sludge hanging about. A power flush never gets it all out.

Is the Magna booster a reasonable trap?
(seems likely enough, although

The unit is made by Spirovent who make industrial units as well. They make
quality products. £250, when unit costs say £110 is fine for a drain down
and refill. That is £140 for the work which can take some time depending on
the system. And you may find they put new X-100 in as well.

I know one installer who puts pressure reducing value on the system set to
1 bar and leaves it open. He puts 2 cans of X-100 and a Magana Boost. He
will instructs the homeowner to empty the filter using a bucket and turning
a tap until only clean water comes through. That way he has no call backs
at all and the customer has a clean system. His get out is that the PRV is
for fillup only and he left it on by mistake.

I put a Magnaclean on my mum's CH - when I swapped the boiler I spent
a long time flushing the system through, and I then followed the
Keston advice to add a Y-strainer. Every few weeks this would clog up
with something the consistency of grease. In the end I took it out
and replaced it with a Magnaclean which doesn't obstruct the flow as
it collects stuff.


The Magna Boost is a much suoperior to the Magaclean

Did you clean the system properly as per the boiler maker's instructions?
The 'grease' has to be coming from somewhere and a magnaclean or other
such product ain't going to sort the source of it. And if some form of
chemical reaction is taking place sooner or later you'll end up with
having to replace everything...

But still requires cleaning every few weeks of the "grease" or isn't
it trapping that? The "grease" is probably bacteria. Not overly
