    Hi. Looking for advise how to drain a Grant Vortex boiler, I need to add some Fornex to the system.
    When I open the drain tap, I am getting a very slow flow.
    Any suggestion to increasing the drain flow?

    Open a bleeder screw in a radiator.

    Thanks Biker1, sounds like an easy resolve.

    Just rethinking Biker1's suggestion, would the header drain out through the radiator bleeder instead of the boiler drain?

    Are you putting Fernox cleaner or inhibitor in it?
    If you have an open system and it's slow to drain, it might indicate that it's clogged up and in need of a proper cleaning.

    It's an open system

    Fernox F4 leak sealer for an immersion tank drip.

    The little water that drains is clear, but I do have original gun barrel section, downstairs in 2 rooms, but all rads heat up.

    Opening a rad air bleed shouldn't make any difference to draining speed in an open system. It should fly out, unless valve is not opening properly, or a blockage somewhere. Any zone valves> If there are, manually open them when draining.

    I am assuming that the leak/drip is on the heating circuit part of the cylinder?

    No zone valves, drip is on the boiler supply into the immersion. I'll go checking for a blockage.
