Heating Inhibitor with a combi boiler

[baldyman26]

Can somebody help, I have a combi boiler. Recently I installed a chrome towel rail in the bathroom, however within a year it had rusted quite badly. The manufacturers did change it although they recommended I use a central heating inhibitor. Looking up on the internet it recommends I put the inhibitor in the header tank, however because I have a combi boiler, I don't have a tank. Is the manufacturer talking rubbish, or do I need an inhibitor. If so how do I put it in the system.

probably too late to add inhibitor as you cannot inhibit was is already there

do a search on flushing central heating system

Thats the thing I havn't tried yet, will it work if I put the inhibitor into the new towel rail will the heating pump it around the system

you can squirt it through the vent on one of the rads (true) but it would have been easier to put it in while you were fitting the rail, before refilling and repressurising.

If you look at vendors of inhibitors you will see they sell a concentrale in a tube for this purpose.

You might consider using a chemical cleaner first to remove some of the old rubbish that the syst will contain.

John how can inhibitor help if the system is sludged up to wotsit?

Thanks for that, I havn't fitted the new rail yet anyway, I will drain it and put the inhibitor into the rail before filling the system back up.

Cheers for that

There was quite a bit of muck come out when i drained the rail

then give it a chemical clean. at least. Inhibitor will stop it getting worse.

Adding a Magnaclean will trap the black sediment that remains (there will always be some). It wil wear out your pump and clog the boiler, may cause blockages if you don't clean it out.

 

[baldyman26]

Can you add chemical clean and inhibitor at the same time

 

[JohnD]

you have to flush out the cleaner with all the muck it has washed out, so you would be tipping your inhibitor down the drain a week after putting it in.
