    Hi, I have an oil fired pressurised heating system.
    Before I turn on the heating everyday, I have to top up the system to 1 bar .
    I cant see any visible leaks and as soon as I turn on the filler valve gauge flies up to 1 bar in seconds.
    As I said, I cant see any visible signs of water and Im a loss at what else it could be.

    All help would be greatly appreciated.
    Thanks lads

    Pressure vessel is say. Red round cylinder anywhere. When the systems to zero put a gauge to the nipple on top of it. Should be 0.8-1 bar.

    If your pumping up you need to drain water off as the pressure is with no pressure against it

    Thanks very much corkgsxr.
    I checked the vessel and it was reading under a bar, so I pumped it up to the recommended(printed n the side of it) bar and a half while the system was NOT pressurised
    Would this be right? Thanks

    Not quite. pump it to 0.8-1 bar.

    Is the water side staying at 0 when you have it pumped up. If not release some water until you have it at 0.8-1 bar at the nipple and 0 system pressure.
