    As title - after a combi boiler is totally switched off (CH has been on) after what amount of time would you expect condensate to stop dripping?
    Thanks!

    there is no set time , but if it is dripping when the boiler is cold it could be the heat exchanger, have to say your boiler is not one of the usual suspects with that fault, are you having to top the pressure up constantly ?

    Yes, losing pressure. Needing to top up weekly now. No issues with PRV or pressure rising. Expansion vessel fine etc. Boiler is dry as a bone otherwise and very clean. No leaks in pipework or rads/valves, not even a weep. Just two rooms where I haven't checked the pipes under the floorboards.

    Otherwise had great experience with Biasi. Had an Ideal Isar which was a nightmare but even once I got used to its issues it was fine. But Ideal's engineers left a leak on a repair & then misdiagnosed & subsequently just made up a fault to condemn it just after I'd paid for a new heat exchanger.

    Well let the boiler cool down and check to see if the condensate is dripping with the boiler off, as already said not a common problem with your boiler

    Already did that. Turned off for 4 hours and there was a drip every 30 seconds. Just wondered if I need to keep it turned off longer.
