Yes that’s right no pressure. Hence why I’m trying to fill it. Not sure what the valve is for, it’s hot and cold joint for what is marked with a factory symbol. Grey water perhaps?Left hand gauge is reading 0 so you have no water pressure or a faulty gauge ?
Also what's the silver valve for just out of the pic top ??

YEp, all taps working fine. Judging from the manual it should be reading 1.5-2. There’s definitely mains pressure as when I disconnect the pipe from the inlet it rushes out. It’s not getting in. I presume the gauge is correct as the radiators are still cold, or Luke warm at best.That's your incoming cold mains that has no pressure/ gauge is faulty
Do you have cold water to your taps ?
Just checked, water is flowing from both. But if the gauge is faulty why is there still no heating?If you disconnect the hose from the heating side and turn on the inlet does it come out of the hose. (Prove the hose is not blocked)
If it’s not blocked, open the heating valve into a bucket to prove that opens. If that works it could be the heating gauge is faulty.
