Bled radiator last night….no heating this morning!

Heating system was making some funny noises, noticed that one of the rads upstairs was cold 1/2 way up. I bled it and let out loads of air – the rad heated up ok straight away.

This morning the house is ice cold. :#

Checked the control and the heating says it on, turned water and heating off, switched heating only on a I can hear the pump start but nothing to any rads.
Its not a new system, prolly around 15 years old when the house was built.

    What’s your psi? You should have at least 10 or so in there.

    Guessing that your system pressure dropped. And you don't have a fill system , (or it's a manual one, ) and you pulled air in through vents somewhere. This would mean that you most likely have a leak. Or the expansion tank failed, And with no automatic make up, your system pressure would drop. So the pump wont circulate water because you're air locked.
