0 Bar pressure on boiler

[elbeeuk]

Hi all,
Sorry if I'm asking a really easy question but my radiators upstairs are only heating halfway. I've tried to bleed them but no air(or water) comes out.
I've looked at the pressure on the boiler and it's reading 0 bar.

The cylinder is a Tribune HE TI 150:

Is it straightforward to get the pressure back in the system?
My old house had a combi boiler and it was a straightforward turn of a valve to reintroduce pressure to the system but I'm not sure with this one.

Sorry if this has been asked a million times, I just wasn't sure what to search for.

Cheers in advance

Same as your old com I boiler mate, when you look at the cylinder in the airing closet you will see the silver braided pipe with 1 or 2 valves on either end, just turn the handle till pressure teachers 1 to 1.5 bar then shut off. Keep an eye on the pressure over the next few weeks tho incase there is a problem with the system

I'll give that a go.
