How do I know if expansion vessel faulty

[king of pipes]

Think your worrying a bit to much the system will operate perfectly well at those range of pressures get it checked and serviced in March ok . Cheers kop

Keeping it simple: once all your radiators are hot through, the pressure is not likely to rise any further than it has already.

Perfect thanks for your time guys

So does that mean it’s fine then my boiler for heating is set at 70 so Im assuming rads etc would reach that in 2hrs and hasn’t ever went above that tiny bit above the 2.2 so I’m assuming that’s fine? If it was to continue to rise to 3 clearly there would be an issue?

Yes, it looks like your system is working within limits, so no worries.
Systems typically do increase their pressure by a third maximum when hot.
But do as I say, drop the pressure slightly and get your service engineer to check and recharge the gas on the expansion vessel at next service

Blimey. Glad I have only just seen this thread. I’m exhausted just reading it.

Pressure too much also for you?

I'd suggest breathing in and out of a paper bag, and have a nice sit down.

as long as it’s working within the limits I will get the service dude to check it I know sorry guys I’ve had probs with previous boiler n I think the old insecurities still there cheers for help and advice as always

Be aware that the gauges aren't calibrated and are just a guide.
If the expansion vessel isn't working the pressure can go to above 3 bar within 15 minutes.
