Grant Vortex Pro Combi 21e oil boiler - slightly high pressure

[Eriskay]

The pressure is currently showing at 2 bar - is it OK to run it at this pressure, and if not how can I reduce the pressure (or is this a job for the engineer)? Many thanks.

If it is showing 2 bar when hot then don't worry about it, this is not far
normal.

Check the pressure when the boiler is cold. Should be around 1 - 1.5 bar.

Check that the filling loop not letting by. You can reduce the system pressure
by opening a vent nipple on a radiator and letting some water out.

If pressure continues to rise then get it looked at.

Thank you heliotrope - that's very helpful. I'll let a bit of water out via a radiator to drop the pressure down a little - I didn't realise doing something as straightforward as that would do the trick! I'll keep an eye on it and see how it goes.

Thank you Grant UK for this helpful information. I managed to reduce the pressure as suggested and so far it's remained stable. It's very useful to have this contact number and email for future reference.
