Balancing radiators, fairly easy takes a few days to do.
First, a few things to bear in mind.
Radiators have valves on both ends. The first valve (inlet) is the FLOW valve, the outlet is called the LOCKSHIELD valve.
The flow valve will open and close by hand, or it may be a thermostatic valve.
The lockshield is generally a cap, and does not operate the valve underneath. You sometimes need to pull the cap off, or unscrew a pin to in the top to get to it. If the system was installed wrongly, you may have a standard valve both ends. If this is the case, the valve which gets warm last is the lockshield.
Go around every radiator in the house and turn the flow valve fully open. One by one, close the lockshield valve totally, then open it half a turn.
Unfortunately, water in heating systems flows the easiest way back around the circuit, so sometimes a radiator may rob another of its heat.
Run the system for a day or so, then if you need a little extra heat in one room, crack the lockshield an extra quarter of a turn.
The worst thing you can do is open all the valves fully, this just does not work.
Eventually, you will find the head pressure stays up on the circulator pump and manages to get warm water around the house.
If the valves start to leak around the spindle poking out the top, in most cases a slight clockwise turn to the nut under the spike will tighten up the packing a little, and stop it leaking.
Dont force anything as they break easily and water makes a mess.

Open all inlet and outlet radiator valves in the house. Start from the top floor and half close the inlet valve on each rad. Work your way through the house. You will notice the difference. Also, make sure there is no air in the system. A special key is needed for this and to bleed them simply open the little valve on the top side of the rad, you will hear the air come out, once water starts to spurt out close the valve. Best to do this for all rad's in the house. Hope this helps.

you see the tap on the end of them you have to get all the air out of it
turn the tap till you hear the air but have something under them as water does escape to
you need to do this to all the raidiators in the house 1 by 1
then the 2 that dnt work should be ok if not you could have a blockage so need to call a plumber to sort it but most of the time it's just trapped air
good luck

Try bleeding air from the system, but if that fails try de-sludging the radiators, drain the water from the system, then disconnect the pipework from a drained radiator and empty the sludge out.
NOTE: don't get sludge on the carpet as it will stain.
Flush out with a hose pipe, outside the house, refit and bleed system again.

They need bleeding. When the system is on, locate a small hole at the top of the rad. and just inside you will see a small hectagal thing sticking out. Get a key and slowly turn it, you will hear hisssssing as the air escapes, when hot water start coming out, tighten it up. Buy a key at any DIY store.

I don't know about 'balancing radiators' - are they wonky? Sometimes they need 'bleeding' in case there is air in them preventing the hot water coming through them. Or ... maybe there is a central heating person waiting to answer. Good Luck.

hopefuly you'll have a radiator key, just use it to turn the nipple (maybe...) in the top of each radiator until it stops hissing and water comes out... that should get all the air out of the system and let the nice hot water fill em up!

I think they must need bled. You have to put the radiator key in & get all the excess air out

I heard somewhere that you have to bleed the last radiator in the system, which allows all trapped air to be removed. Bleeding radiators randomly doesn't solve the problem.
