    Hi guys

    I moved into a bungalow and recently removed the hearth,fireplace and back boiler

    The back boiler used 3 tappings

    The top tap is the flow to the cylinder
    The bottom 2 are the heating flow and return

    To give me heat and water I connected the 2 flows but now there is a massive amont of air being drawn into the system - at the start of every day I could bleed the 2 rads first on the system almost completely

    I reckon it is coming in through the open vent at the header tank

    So

    1. am I right

    2. Can I put an automatic air vent on the open vent(problem being I don't know if these allow steam out in case anything did ever overheat at the cylinder but it would cure the intake of air surely ?)

    Many thanks for any help
