Help please - condensing boiler in apatment complex - exhaust issues

    Hello all,

    the gas boiler in my apartment needs to be replaced.

    I have been told that new boilers are nearly all condensing boilers, meaning that considerable amounts of steam are exhausted.

    The problem is that the apartment is a ground floor dwelling, with a balcony above, meaning that a plume diversion kit is not allowed.

    The Management Company have told me that I must have the exhaust diverted to the nearest downpipe.

    Im my case this would invlove running piping from the boiler exhaust, down the wall, then about 15ft along the ground and into the downpipe.

    Is this compatible with how a condensing boiler operates? My understanding is that obstructing/diverting the exhaust is quite critical.

    The management company are seeing this issue a lot now, but have yet to act.

    Is it still possible to have non-condensing boilers installed?

    Thanks

    Sounds like the management company are a bit mixed up.

    A condensing boiler does need a pipe to the downpipe to carry condensate, i.e. just water drips.

    The exhaust can be extended to the edge of the balcony, I've seen it in many apartment complexes I've visited.

    Re: Condenste.
    Condensate is slightly acidic hence the regulation states that it should be taken to a suitable gully, however you can use a suitable soakaway that is filled with limestone to neutralise acidity.
    Fairly simple to make utilising 4" pipe and drain covering.


    Re; Plume Kit.
    You can get fairly long extension unfortunatly can be costly.
    Some Mangement companies are aware of update building regulations re: the requirment for installing condensing boilers but you are setting a prescident in you block and ask them to seek advise from the original Builder/Engineer/Architect.

    Also the local council planning department may be able to help!

    You can still get standard efficiancy boilers but RGI's are only allowd fit them when all other means of safely getting rid of the condens and flue postions have been exhausted. It sounds like there are options availibe to do this so by right you can not get a standard boiler fitted.

    As the other poster said it has to go into a foul drain or soak away and plum managment kits are availible to deal with the flue.

    Either way you need a boiler for heat and hot water, and the managment company probably have there cards close to there chest and want a quiet life.
