The questions is how to choose between 「いれる」 and 「はいれる」.
As far as I know, the same kanji is used for both (入れる). How can one make the distinction when reading a text?

You say X に [入]{はい}れる, but X を [入]{い}れる.
The answer to these type of questions always seems to be the same, but you need the context to decide on a reading for a particular 漢字. There are many examples for when the reading of a 漢字 is dependent on the context, and the word pair you quote is one of the easier ones to guess, because [入]{はい}れる is an intransitive verb and [入]{い}れる is a transitive verb and there is a definite answer and a definite way to find out (i.e. check whether the sentence has a direct object marked with を and you know it has to be [入]{い}れる).
