Having read all the threads here back to the beginning, I'd still like to ask which system you each refer.
What do you use for heating system de-sludging before fitting a new boiler? And which for cleansing and inhibiting after installation?
Seems to be three manufacturers in commonly use. Fernox, Sentinel and Kamco. Fernox have a confusing array of offerings, Sentinel seem well regarded, and Kamco are rarely mentioned here even though ShoreHeat (my local spares supplier) sell stacks of their products.
Which do YOU use? All comments much appreciated.
Cheers, Mike.

Only use fernox when no other alternative IE have to put in thru bleed on rad` too expensive. Sentinal x300 or x400 then x100. If system is really black ferroquest but it is very strong and wouldn`t risk it on old system.

Your concern is a matter of pure boiler water chemistry.
I can give you a lot of information, i propose you to avoid the trade name chemicals. Non -expensive , pure raw material chemicals are doing perfect job.

Perhaps John P Chemical you should tell us more, for the whole world to read, and for us to discuss.

Very happy and thanks for the respond to my comments, regarding the cleaning of a new boiler or a boiler after after major repairs..
The whole story is better known as
pre- commissioning Chemical Cleaning..
Scope of the work is to remove (1) sludge, )2) protective oils , (3) greases (4) general dirtiness , (5) mill scale (6) welding fluxes and possible rust.
It is clear untill now? It is necessary, as well as, to understand why the subject removal is a must..
REVERTING AFTER INTERESTED COMMENTS...

John you say "Non -expensive , pure raw material chemicals are doing perfect job".
But for the lesser mortals (eg me) who have no chemical background what are these raw material chemicals and where can they be obtained.

HI ALAN..
YES THEY ARE VERY LOW IN PRICE...
e.g TRISODIUM PHOSPHATE ( TRI-NAL)
or SODIUM CARBONATE ( CARBINATE SODA)
YOU CAN FIND IN NEXT DOOR PAINTERS HOUSE, or DRUGSTORE..
HOWEVER, MAINLY YOU OR YOUR CUSTOMER HAVE TO SPECIFY THE SCOPE OF WORK...
AFTERTHAT AND AFTER RECEIVING DETAILS OF THE BOILER, I CAN GIVE YOU THE CLEANING PROCEDURE.
