Cold radiators!!!!!!

[Dan2505]

Hi
I turned my heating on few days ago for the first time this winter and bleed the radiators and it all worked fine.

Turned it on again tonight and the boiler fires up but all the radiators are stone cold!

Any advice on what it could be?
The pump in the airing cupboard is pumping

If it’s an external pump then I’d say you have a motorised valve or 2, any ideas on your setup?

I wouldn’t have a clue what set up it is

Ok, you know you have a pump, what else do you have with it? Post a photo of the cylinder cupboard, failing that get a plumber out, G3 if unvented cylinder.

Is the hot water ok, if it is the motorised valve is not working or the system has managed to block either the flow or return pipes to the boiler

Your room thermostat turned up?
