Which Sentinel product to use?

[newnhambolton]

I am replacing 5 out of the 8 radiators in my new house, due to excessive pinpointing, etc, which will involve a small bit of soldering of pipework.

I also suspect that the central heating system has never been cleaned.

Should I use X400 - sludge remover after installing the radiators or the X300- cleaner? I am also relying on a gravity flush.

Next year, when I have saved enough money I will replace the boiler, which at that point will be powerflushed by the installer.

x300 is for new systems.

x400 will do the job nicely.

With five new radiators I would be using X300! Followed by X100 !

My advice if some of your radiators are pinholed are to replace all of them as thats the result of severe problems.

I do hope that your problems have been cured! Any pumping over can pinhole new rads withing weeks!

Bear in mind he is REPLACING 5 radiators tony, so all the pipework, existing radiators, pump etc will still be left with magnitite sludge. x300 is for systems less than 6 months old, and really only for cleansing the system of flux residues, swarf etc.

Do agree with replacing all the radiators though.

And for removing the protective oily coating on the inside of rads! Thats why some installers use washing up liquid saying its just as good.

The OP is thinking that the sludge will be removed later when a new boiler is fitted.
