Have you checked the temperature set on the boiler's thermostat? (not
the room stat, but the one the boiler itself that controls/limits the
flow temperature from the boiler)

If the system has been drained and refilled, its not unusual for some
rads to need bleeding over a few days as all the entrained air comes out
of the fresh water used to refill the system. This air will often
accumulate in the first rad in the circuit...

You also need to make sure there was adequate corrosion inhibitor added
to the system after it was refilled - otherwise gas production from
corrosion will occur and cause further need for bleeding (not to mention
damage to the system).
