Air lock in pipes feeding radiators? Turn off all radiators except one
that's not getting hot and perhaps turn the pump to the highest speed
for a short period.

The bathroom radiator in the cottage we rented a couple of weeks ago was
cold despite the pipes to and from being hot. I luckily the bleed screw
was slotted so I didn't need a key to bleed it. Once bled of more air
than I ever bled from one rad in the past it worked perfectly.

I told the owner what I had done when they called in later in the week.
The response "Bled ??? sorry I don't know what that is" !!!
