New column rad cold devastated

[Elitecriteria]

New double panel column radiator

Cold

Turned off all rads not helped

Checked trv pin seems fine

Locksheild i think is ok see pic sttached

Its new so didnt need to flush

Cant really balance because the only thing that is hot is the copper pipes

So instructions came with it about how it flows or something i chose option 5 both my trv and lockshield are at the bottom someoje said one trv should he at top and one at bottom but iv never seen a rad with valves one up and one down

See pics

Hello guyS

I have not tried what youbsaid

But i have felt the first three columns are warm and the bar across atthe bottom is warm


The rest 11 bars towards right mostly top and middle area are cold

Is/was the full length of the rad top warm/hot?.
"Ordinary" single+double pannel rads start off heating initially like that. If you bring a rad into service with the CH water already up to temperature you will see this effect. The hot water will rise up in the first say150/200 MM length of the rad at the inlet end, it will then get hot all along the top and gradually heat the whole rad from the top down.
Its unlikely, but there may be a baffle somewhere in your rad, if NOT in the top (rad upside down) then you can check it by shutting the TRV&LSV, open the vent screw to check that the valves are tight, remove the both blank plugs on rad top, get bit of stiff wire or a bit of copper or plastic piping if its OD is small enough and you should be able to push it right through from one end to the other, you may be able to check it simply by holding a light up against one end. If it does then of course, more messy but the same could be done in the bottom.

Morning, sounds like it's piped the wrong way round, try swapping it so flow goes through it the other way. Often the baffles are a column or two before the return.

Thank you john

The bottom is warmer

Top is not

Ill open the vavles and check through

Also it may not even help but im going to move my bleed valve to the other cold side to see if that helps and bleed on that side

This diverter is 145mm long and inserted at the inlet end.
