Double radiator cold on one side, hot on the other

[andyedinburgh]

We've a radiator upstairs from the boiler that is double and the back side gets hot but the front doesnt. The heat or lack of it is consistent at the top and the bottom, although the very bottom is warm close to the pipe.

It looks like an old radiator and the in/out pipes are all on one side.

Any thoughts
Thanks
Andy

take it off and put a hosepipe in it

while its off open both valves (one at a time) into a bucket and check the flow

have boiler / pump off while you do

Has it got 2 bleed valves - one on each rad @ top

Only one bleed valve on it for both sides of the radiator.

Was it working okay previously? If so, remove rad and flush both sides. You have a twin entry valve, which should have a distribution tube that may have become disconnected. Double rads are not normally any good with twin entry valves, which is why I am asking about the history.

Hi expertgasman,

After google-ing for 2 hrs finally I found your reply. I have recently removed my twin entry valve connected double panel rad for cleaning. When I took it out. The distribution tube was not connected with valves, instead it was loosly connected with radiator - In all the other's single panel rad it was connect with the value. I tried to pull it out but it wasn't coming out. Looks like it was bend inside towards the back or front panel (Not sure if this was done intentionally).

So, I flushed all the radiators including double panel one but now all the rads are working except double panel one. I tried turning off all the rads except double panel but still not working.

Just wanna know in double panel rad, which side the tube should be connected with? value or rad.
