New radiator installed not warming up from one side

[aspurewal]

I ran the pipes from an existing heater, which heats fine,

The left hand pipe heats ok on new radiator and pipes running inbetween are also hot.

The right hand pipe however is only a tiny bit warm, all the way from the Junction that was put in.
The pipe goes up into the old radiator and the junction routes water to the left curving 90 degrees down then 90 degrees right and then runs to new radiator.
This pipe is slightly warm if that.

I have bleeded the new radiator, and it seems to be full of water, only the top of it heats teh bottom is cold

Please help.

Is this in your own home?

Have you balanced the system ( see FAQ ) ?

Are the pipes to the new rad in 15 mm and how long are they?
