If you have a ladder style towel radiator in the bathroom, you can add inhibitor by closing both valves, removing one of the plugs at the top of the radiator, syphoning out some water, then pouring the inhibitor in. Replace cap, open valves, bleed radiator.

Failing that, if you dump it into the expansion tank, it will eventually work its' way into the system through expansion and contraction of the liquid. It'll just take longer.

Theres an easier 'lazy' way 
You can buy inhibitor in an aerosol can.....any rad will do....turn off both valves either side of rad....take out bleed screw.....screw pipe attached to aerosol into bleed valve....open valves either side of rad and hit the 'go' button on the aerosol.....when can is empty....turn off valves again, remove pipe and refit bleed screw.....turn on both valvess again....job jobbed  but it isnt cheap...

Ffs only just seen this,was at a loose end yesterday and could have popped over with err all the correct tools that i have in my garage

One bottle should be enough in a normal domestic system



I used this kit from Screwfix to get the contents into the towel radiator (as described by KW). It is easy with the towel rad because the air vent is sealed with an O ring but it is not much more difficult with a bog standard rad where the air vent is sealed with PTFE tape.

Academic now I know, but why exactly did you have to drain down?

Do not ever rely on a thermostatic valve to be closed permanently while doing a rad change or removing a rad for decorating ,depending on the type installed you should have been left the decorators cap which replaces the head,reason being some are designed to open up if it gets cold and you could be in for a flood,

[chrisgixer]

I'm confused. How does closing the rad valve enable removal without bleeding either the rad, or the system...?

One or the other will leak. What have I missed?

[martin42]

Close both valves ,stops water,in theory,then crack open nuts nearest to radiator and place a container underneath to catch water,and drain that way,unless you have the know how and rad is small enough ,undo both nuts completely at the same time and then press thumbs over the tails on rad lift up and flip over and then take outside to drain,dont do it after heating has been on tho

Bleed valve is still closed, so what is easier, drain one rad with it closed or whole system? Still, as I said, academic now.

Ahh, I should have paid more attention to the question

What he said, piece of p**s

TRV screws straight into rad. So either the valve has to unscrew (thus disconnecting the feed pipe), or the rad has to unscrew (not practical).

[Shackeng]

I was originally suggesting that you should be able to crack that nut behind the 46" mark, and drain from there, or the other end, with both valves off, thus avoiding a full drain down. The stuck bleed valve just makes drainage, either single rad, or system, marginally more annoying.

I know it's all done now but, if anyone has the same problem with the bleed valve, and the rad is to be sacrificed, drill a small hole somewhere near the top to let air in.

I know it's all done now but, if anyone has the same problem with the bleed valve, and the rad is to be sacrificed, and their electric drill and bits haven't been recently barbecued, drill a small hole somewhere near the top to let air in.

Fixed that for you.
