Hey All

I have a Radiator in the Living Room which is not getting totally hot.

The Radiator was installed a few months ago and has never worked
particularly well.

Looking at the Radiator just before the in-flow below the TRV the pipe is
very hot, and just after the TRV it is hot but only the top front (double
skin) of this big radiator is warm and gets colder towards the bottom.

There is not sludge in the Rad as it has been hosed out

any advice would be appreciated

I have a conventional micro-bore system, with a pump and stored hot water.
