How do i add Central Heating Inhibitor?

Canucklehead

By the way the water was proper dirty but i'm hoping i've stopped it getting any worse. Seems strange that someone would install a brand new system and then not add any protector to look after it.

Hi...having reads lots of posts here it seems the reverse would be true i.e. if get a cheap quote you get it a cheap job... 'the fit it and run' school of boiler installation to be precise:eek:

I have just been reading this post and found it useful.

I want to drain my system, flush it and then replace the inhibitor. I would like to use the filling loop for putting in the cleanerand the inhibitor but I am not exactly sure how to do this.
Anyone have the 'idiots' guide?

isolated the radiator and drained off quite a bit of water from the radiator by opening the lockshield valve connection to the radiator.

injecting the concentrate in through the tiny hole left by removing the air vent pin didn't work all - the hole very quickly became blocked. I removed the 22mm nut around the air vent pin and i didn't realise that entry into the radiator itself was 90degrees off from the 22mm hole. Trying to lodge the applicator into this hole and then adding the concentrate wasn't fun :mad: Removing the 22mm blanking nut at the opposite side did make getting it into the system a little easier though, but i ended up with the stuff everywhere!

I found that exact problem as well, ended up losing about a 1/6 of the inhibitor before I gave the idea up. In the end I had one of my rare bright ideas - closed off the towel radiator in the bathroom - the blanking nuts are on the top of these and just poured the remaining inhibitor in. Hopefully the system has enough in there.

Hi

I have just had a new radiator in my kitchen. I ask the plumber who fitted it to make sure he put some more inhibitor into the system, but I am not sure if he did. Not long after I got British Gas, who were testing my boiler at the time, to test if there was any inhibitor in the system, be he did not have a testing kit. But to cut a long story short I eventually got another British Gas man to come but guess what he did not have a testing kit either. So he phone one of his work colleague for advice and he said he could put some inhibitor in the system (he said you could not over dose the system). He then proceeded to do the job. That was well over two weeks ago and now all I am getting is the smell of the inhibitor from that radiator when it is on and also it smells a bit when it is off, which is in the kitchen. It smells terrrible. Does anybody know if this is dangerous to breathe in and how long before the smell goes away?

I'm not sure how you can smell inhibitor when it is inside the radiator. I would have thought that what you can smell, is inhibitor that has been spilled on the outside of the radiator. I suggest that you give the outside of the radiator a thorough clean, particularly around the filling hole, and dry it well.

I have tried this but it still smells, is breathing in the fumes dangerous does anybody know.

Hi,

I am in the same boat. I have bought a repossessed house and need to know about recommissioning the system. Any advice please.

Hi

Simple way to do a DIY central heating inhibiter concentration check.

1. Two glass jam jars, (eat the jam first).
2. Open a bleed on one radiator and fill one jam jar with radiator water. Label "#1 SYSTEM"
3. Fill second jar with clean tap water, label "#2 CONTROL"
4. Obtain two 4" shiny steel nails and place 1 in each jar of water.
5. Place both jars out of the way, preferably covered for a few days
6. Check condition of nails

If you have good inhibitor in the system, the nail in jar #1 will still be shiny but the nail in jar #2 will be orange with rust.
If there is a degree of oxide in #1 then you will want to add more inhibitor to your system.
