The pressure in my Gloworm combi boiler is adjustable, it cuts out below
0.6 bar.

Where is this pressure, is it in the radiator section or the hot water
and what are the advantages of working at the minimum pressure or higher.

See the Sealed CH FAQ.
In the radiators, many advantages.

You only need enough pressure-water to get water to the highest
radiator, On the boiler is a pressure relief valve that opens if
pressure is to high, and they go bad. To high and it can crack open
the boiler. Lowest pressure will make it last longest.

Thanks Ed, very interesting. Especially the bit about being able to
flush the system using the mains water.
