Central heating additives

[chriselevate]

Now that my heating system is back and running (see previous post for the gory details) what's the best way to keep the system water in good condition?

I hear you should leave a additive in for a week and then flush it out 2-3 times. Following this I hear you should use a product in the system to keep it in good condition. Is this correct? What are the types of products to use?

Thanks for your help and advice.
Ps.. not a pressurised system so I guess I drop it into the header tank when empty(ish)?

Where do you "hear" all this? Down the pub?

Reading the FAQ and Wiki on this site and previous threads will tell all you need to know.

Heared it all just by reading around. I've found lots of threads on here but a few different theories/pieces of advuce. Was just asking for the one the best way of doing it.

Bottle of Sentinel X400 can be left in for a week or 2 without issue to help clean the system, make sure this is thoroughly flushed out, then add a bottle of X100 as an inhibitor to prevent further corrosion within the system.

I have to disagree with Hugh here!

X400 needs at least 4-5 weeks to be effective.

X800 seems stronger and works in just four hours!

How long depends on the product used.

Please can clarify the best thing to do...

You would do this...
1. Put 1 bottle of Sentinel X800 in over night and flush out tomorrow thoroughly (alternatively the X400 left in for a 4 weeks)
2. After 2-3 flush outs leave a bottle of X100 in the system

Is this correct or does it need an inhibitor to remain in the system?

Thanks.

The X800 (I thought!) was designed for use with powerflushing machines, hence why I suggested the X400 for DIY use!

Whichever you choose to use, either X400 or X800, once the system has been thoroughly flushed out, add the X100. The X100 is the inhibitor, and needs to be left in the system.

Should the system be either partially or totally drained in the future then it would be prudent to add another bottle of X100 to maintain the protection.

X800 can be used for 4 hrs with the heating turned up to let it run around the system/radiators.

X800 is (well seems to be) a stronger fomulation, designed for use a powerflush. But can equally be used on it's own, and of course, makes much more sense for a pro even without a power flush because of the time factor.

For DIY, I think if a system seems really clagged up I'd use X800, otherwise, chucking x400 in a leaving it for a few weeks seems fine (It's what's happening in mine right now, after finishing some system modifications. It wasn't showing any dreadful symptoms, but it's old and I don't know it's history, and it doesn't get drained very often, so it seemed a sensible precaution.)

They designed a product called Ferroquest for BG to use for power flushing because they realised the X400 was rather too weak.

After a few months of only supplying it to BG they then made it available in a rather limited way to anyone.

Later they renamed it as X800 and sold it as a general rapid cleanser that can also be used for power flushing.
