Vokera 280 pressure too low??

[karenh]

Hi, I live in a rented house with a fairly new Vokera Compact 280 CH system. I've noticed the radiators are only becoming warm halfway up, and the pressure guage is about 0.5 bar. I think I need to raise the pressure, but having no manual I'm not sure how to do this.

Can anyone point me in the right direction?

should have on of these

or it could be tank fed

Think that's solved it, the pressure has crept up to just over one. Had a bit of an issue switching it off because I only turned it on ever so slightly, but it continued to hiss quietly unless I was holding it shut. It seems to have stopped now. Radiators feel warmer already!

Thanks!!

You'll probably find some / all rads have air in - will need bleeding. Then more water added.

Keep a check on how often you need to top-up the system. Should NOT be more often than every 3 months.
