    This is a common problem where I have to install a condensing boiler and there is nowhere to discharge the condense.
    I have an oil boiler to install in a garage and there is only a rainwater gulley close by.
    To install a condense trap in the ground is too much work.
    I am thinking of using something internal to neutralise the discharge first, before running it to outside.
    What would you recommend?
    Is there a simple solution?

    If pumping to outside then there are lots of choices.

    I won’t be pumping it. The garage is above ground level and the rainwater gulley is about 3m away.
    Just thought if I can comply with regs to neutralise the condense inside the garage first somehow, then just run to gulley outside

    Not a problem best fit a pot in the ground it's a 2 hours job at most fill with limestone chippings up size the condense waste pipe to 32mm and lag up . Or you can get a inline neutraliser again upsize to 32mm after this and connect into the rainwater gully but make sure you have a air break incase of the drainage backs up and lag up . Kop

    I'm confused, why do you need to neutralise the condensate before running it to a gulley?

    Presume he means the little grill
    Outside the garage door? Could be wrong though.

    i think its because its a rain water, rather than general sewage drain.

    The way I read the post was that it didn't go to the main soil, but could be wrong.

    That’s what I presumed as well. He used the word gulley.

    Ok so if the rainwater goes to a soakaway do you have to use the neutraliser? I guess that would be the same if you created your own soakaway?

    Yes & Yes.
    (Note I didn`t take a cheap shot about common knowledge) ;)

    Yep when you create a condensate specific soakaway you put the lime chippings in there to neutralise, if its going to a general rainwater soakaway you have to do it beforehand.

    (still in middle of studdying for my gas safe so might not be 100%)
