Wodca still plates or high reflux?

[Whotan]

 I have a 35l and an 80l boiler!
Both are powered by a large shotgun capacitor!

I plan to make vodka (neutral alcohol)!
My stove has 4500w power!
How high can I build the reflux to get the greatest possible purity (neutrality)?!

And which design would you advise me to use?
I could build a maximum height of 2m!
Since my ceiling is 2.80 high and the big pot already has 80cm!
Would that be enough to distill a super neutral alcohol?
