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

Flow and return correct way round ?
Many of that type of rad have a baffel in bottom and are flow specific.

 

[Elitecriteria]

Hi but the valves i got are bidirectiona will it mattr?

 

[snowhead]

Is the lockshield fully open?

Was there a radiator in that location before and if so did that work O.K?
If so was it smaller / larger / similar sized a the new one?
Where do the flow and return pipes originate

Could that radiator be mounted either way up, was there a sticker indicating Top /Bottom?
If there is a baffle in one of the headers it may have ended up at the top instead of the bottom although looking at the drawings I think they would have marked the baffle on there if there was one.

It should work flow and return in the bottom, if it did need to be top / Bottom there would have been a label on the radiator.

No we had to put new copper pipes from walls

No sticker was on it at al

Really confised as hell

They sent a product certificte that explained tue inflow which i attavhed above

 

[ShaunCorbs]

Is the bottom of the rad hot ?

 

[Elitecriteria]

Inflow is where trv is…..

 

[Elitecriteria]

Not that hot

The copper pipes are hot
Both sides are trv side hotter

Lsv warm but not hot

The only hot partish is the trv side top part rad

Bottom not that warm

 

[ShaunCorbs]

And if you turn all the other trvs off on the rads it doesn’t get hot / any hotter

 

[John.g]

The product sheet says "When we place the order we will enter the ERP for the upper and lower", what does this mean.

Mabe shut both valves, remove the vent and then prove flow by alternatively opening/shutting valves.

 

[Elitecriteria]

When you say remove vent u mean the cap on top of the lsv valve

Then close both valve open one and see which lets waterin?

Bleed screw at top of radiator

 

[John.g]

No, on the top of the rad at one or both ends you should see blank plugs one of which should have a vent/bleed screw that you can open/remove with a screwdriver or a key.
Slacken this after shutting both valves, then remove it completely, put a dish/bucket under it and then open say the TRV fully first and you should get a good flow of water, shut the TRV then do likewise with the Lockshield valve.

Ok i did bleed it only water cameout

Ill try this lastthin
So

Where u bleed it take that whole part off from
The radiator then turn on the trv open it

Let watwr come out


Then go on other side take the bleed valve out that side and open lsv so water comes out

Generally what is this doing? Because it has got water in it

No

 

[ShaunCorbs]

Need to remove the rad and put a piece of copper tube between the valves eg linking them and test like that if it works rads rubbish

 

[John.g]

Jyst remove the bleed vave at the end above the LSV and leave out, after first ensuring that both the TRV & the LSV are closed, the open the TRV fully, this proves that you have a good flow from/via the TRV, close the TRV and open the LSV fully, this then proves that the LSV has a good flow. All this proves is that both valves are working as they should.

Just to confirm i only have one bleed valve on the trv side

The other side has a plain one thats all on the lsv side

Oh man i hope not that means iv been ripped off

Ok ill try the othet way and join with copper pipe and see ifthe copperpipe heats up

Doesn’t matter where the water comes out but matters make sure the valves are off and open one check water comes out and close that one then test the lockshield etc
