Column for small kettle

[Demy]

Well, this is my first post. This is my situation: they have been distilling for a few years, experimenting a lot. The quantity I produce is very small compared to what I read on the forum, in fact I distil 10/15 liters on a 1500w electric stove and 30 liters with 2500w electric resistance. I have a 1.5 inch vm reflux column.
Question: with these numbers is it convenient to think of a column with a larger diameter? I've read a lot on the subject, but it's mostly based on larger quantities, so I can't find a definitive answer. Thank you very much and forgive my language!
