Hi I am having problems with my heating. I have heating up stairs. The bathroom radiator is hot the bedroom radiators are warm and downstairs all the radiators are cold. Any ideas what the problem could be? Have bled the downstairs radiators and there is no air in them. Any help would be appreciated

Could be the pump.

as said,
is the boiler downstairs?

heat rises but wont pump downstairs, try and joggle the pump setting from 1-3 for a few minuites sometimes it works if it is slightly blocked.
