Moving a Radiator

[Eddman]

hi there, i have a radiator (first on my system) with the 'fast drain' valve on it. it sits in front of a window in the room that will becvome my kitchen and the window is going to be taken out and replaced with french doors. To save money i told the builder i would move the radiator ready for him to do his job on the window.

I figured this will be my method and i am hoping someone can step in and let me know if i have got it right or if i am missing somthing/doing something wrong!

1. turn of water at entry to house (under kitchen sink) - i presume this feeds the heating system - or is it just taps?
2. attach a hose to the drain valve and open it with a spanner (turning anti-clockwise)
3. allow system to drain and remove radiator
4. go underneath the floor (there is a crawl space) and modify piping with push fit plastic stuff
5. drill holes in floorboards at the new location
6. re-use the copper legs to show above floor level
7. re attach the radiator
8. refill the system

i have heard about adding an additive to the system - where/how does this get added (and indeed what is it!!!)

i hope i haven't bitten off more than i can chew and any help would be appreciated.

thanks again

Eddy

What type of system do you have? what boiler?

If it's a sealed system then -

1. Turn off both valves on every rad except the one you are moving - TRV's without a 0 on them may need decorators caps.
2. Drain down the pipework and rad
3. follow your steps from number 4

Before you fill the system, fill the rad you moved with a 1L of inhibitor, then open every rad, fill the system and bleed and then run till they're all hot and for 15mins after that to disperse the inhibitor.

If it's not a sealed system then it's a bit more complicated.

Thanks Madrab.

How do I know if it a sealed system? I presume it is... I have a combi boiler.

If I choose not to put a radiator back on straight away cap I just cap the 2 pipes underneath the floor?

Do I add the inhibitor into the pipes prior to capping them?

Thanks again for forth coming advice...
