    Hi everyone,
    I'm having a new Vaillant ecotec 430 fitted next week, fitters have offered two install places ( both in the garage)

    1) Outside garage wall = short 1m vertical flue + condensate pump + extended flow/gas pipes
    +£52

    2) Inside garage wall = 1m vertical then 4m horizontal flue but short condensate pipe into internal waste & short other pipe work.
    +£120

    I'm swaying towards (2) with all the shorter/ neater pipe work maybe issues with a pump, just slightly worried the long flue might be an issue ?

    I believe the listed maximum length for Vaillant is around 8m, does anyone know of potential issues of a 5m flues (apart from trickier install)
    Any advice would be really appreciated

    Cheers,
    C

    personally I would go for option 1 long flues do not like condensate and can cause lots of problems

    Flue systems are potential failure points so the shorter the better!

    There seem to be more than a few Bunnys being scrapped because they've rotted out following flue seal failure at the moment Dan it does appear to be a weak spot :(

    Must be a Vaillant thing then. My beloved Intergas are proving very reliable even with creative fluing.....


    *cough*


    :D

    What stopping the condensate pipe going to soil stack?
    Can't it go into a condensate soak away?

    Vaillant boilers are over priced cr*p & their flues leak like a 12 week old Pup.
    As Dan has said, buy an Intergas boiler. Less moving parts & a much better boiler.

    It was an option, bit wary of potential freezing in winter though :(

    I'd go for option 1 with an Intergas boiler matey.

    I'm fasinated to know, only 50 quid to extend the gas & F&R pipes?? I'd charge that for an hours Labour!!
