Comments If' + present simple + 'will' with future reference doesn't properly emerge until B1. In ELT coursebooks there is a tendency to simplify this 'real conditions' structure to one pattern, 'If' + 'Present simple', 'Present simple' ('If you heat water, it boils') usually called 'the zero conditional'. The reality is that there are many more structures that express real conditions.
