How to increase boiler pressure

[Clueless]

Hi

I've just moved in to my first home and I'm a total novice with boilers and central heating systems.
All I ask is which valves in the pic do I turn to keep pressure at 1.5?

See the 2 black valves halfway down the pipes with the silver flexible pipe between? Turn the left one to the vertical position whilst watching the pressure gauge, when it gets to the correct pressure turn both to a horizontal position.

That’s the “filling loop”

You're a star.. thank you

In addition to Stu-B good advice above, You should remove the flexible hose once the correct pressure is reached and put the caps back on. This is a temporary filling loop to top up the pressure when required and is not designed to be permanently attached as per regulations.

As above from Stu and Yorkie boy , fill to one bar when the system is COLD .

never be tempted if your pressure drops regularly to ever push it above 1.5 bar on your boiler gauge. centralheatking

All look good? I had already raised pressure to 1.5 before you replied Townfanjon, but this will be okay right?

Correct spot on if you have to increase the pressure again within a week you have a problem so just keep an eye on it for now
