A bit uncomfortable to click on a link by a newbie.
Upload it on YouTube.
It's probably air in the system. Try bleeding the highest radiator in the system.

It sounds a bit like a blocked heat exchanger/poor circulation, but could be air as above. Also the control knob missing and the red grommet being loose categorise your boiler as At Risk.
