Hi,

I've just moved into a new house and I don't have any hot water. I think it just needs repressurising but I'm not having much luck.

The boiler is a Vokera compact 28.

I've tried turning the black valve (I think it's called the release valve) but no water seems to be coming through. This should fill the pipe so I can then slowly fill up the boiler with the other valve but I can't even get to that stage.

Any advice?

    Hope this info helps
    RE-PRESSURING THE SYSTEM
    The system will need re-pressurising if the red
    LED is illuminated. Locate the filling valve and if
    necessary connect the loop (fig. 3) slowly open
    the valve until you hear the water entering the
    appliance. The red LED will go out first. Go on
    with re-pressuring until the pressure shown on
    the manometer is between 1 & 1.5 bar (fig. 4). The
    appliance must not be operated until the system
    has been re-pressurised. If in doubt contact your
    installer.

    Have a look at pages 9 and 10 of the manual

    Figure 8 suggests there are two 'control valves'. These are basically valves or taps that you have to open in order to fill the boiler. You would need to be sure that both are open in order to let the water enter it. I have a Vokera boiler as well (although not the same model as you) and this is what I have to do to fill mine

    You need to have both valves open at the same time: the tiny volume of water held in the filling loop is not nearly enough to repressurise the boiler.
    If it fails to hold pressure, then you have either a leak on the CH circuit, a faulty PRV, or a faulty EV.
    No free lunch, and no free laptop ;)
