Upstairs rads only warm

[DJseals]

My rads upstairs in bedrooms today only getting warm. The bathroom and ensuite are not used but when trouble shooting today they got red hot when on.

Downstairs rads all get hot very quickly, and hot water works. But rooms only warm. 1 bedroom was cold. I understand balancing a system, but that shouldnt matter if i only have 2-3 rads on upstairs.

I have a honeywell system, hr92 valves and hot water kit, two port to separate hot water and rads. I tried calling for heat and manually opening valves also in rooms and still warm, feed and expansion full and functional. I bled all rads upstairs but no air seemed to be trapped, the pipes in the hot press that I suppose supply the upstairs rads were red hot.

Id love to post a pic but im not sure how

Nothing at all. Rads were not heating few weeks ago while hot water was on so i adjusted balancing valve, but thats it.

No works, adjusted balancing valve to close it a bit so rads could heat with hw on

Expansions vessel pressure is 0, will this affect the heating/rads upstairs

I understand that the balancing valve only effects the return to boiler through the cylinder coil. So if hot water is off it shouldn’t matter?
