Plastic piping for hot water vertical runs

I have been told not to use plastic piping for vertical hot water piping runs. Is this sound advice?
If so why?
I have never seen this advice in manufacturers catalogues.
Thanks texteditor

Hi texteditor,
My understanding is that plastic pipe should not be used local to a boiler. It is important that vertical pipe runs out of the boiler should be in copper.
