Cold Radiators Downstairs

I looked at a system today and the complaint was that not all the radiators downstairs were not heating. One of the smaller radiators was heating but the bigger double radiators were only hot at the pipes to the radiator but the radiator was not actually getting hot. All of the upstairs radiators were heating correctly.

I checked that the upstairs radiators were balanced down as they should be. I also looked at the pump which was set to it's fastest setting. I replaced the pump and all the radiators were working well.
