    I have recently had a Worcester Bosch 30Si boiler installed and it works a treat. However I have noticed that when it is fired up, in addition to the plume there is a steady drip of water that comes from the flue (externally not internally). Is this normal because I thought all the condensed water went down the drain via a pipe.

    Can we have a picture of the flue terminal please and the angle it exits the wall.

    No it's not right sounds like there isn't any fall on the flue

    I thought the fall was built in the flue on the inner duct ?
    I think sometimes the fan can blow a small discharge outside ,also on some moisture does collect on the lip on the black terminal.

    It is but if it is a short length and bad angle they can drip.

    Always cranks the angle up as you tighten the flue flange

    That’s why I recommend Vaillant’s. But will still fit Worcester if it’s what the customer wants.

    Vaillant has been a good boiler for years, I had the first sign written vaillant vans in Bath in 1987 ish complete with Easter bunnies on the back.
