Not necessarily so - you still want the same amount of heat & vapour, its
just that you then go and return say 80-90% of the vapour back to the column
as reflux. My choice is always to maximise the amount of heat input to suit
the column diameter (a method which has its critics). Only in cases where
the amount of reflux cooling is fixed would you necessarily decrease the
heat input to get the greater purity / higher reflux ratio

thats basically the same method as in the "making corn whisky" book by Ian
Smiley - reduce the amount of reflux, so that more flavours do come through.
Its all about adjusting the ratio of reflux to vapour to get the purity you
want. Since its a reflux, you can do it either way - decrease the reflux,
or increase the vapour rate.

for me electricity is convienient. Gas is perfectly fine to use, provided
you follow safety guidelines, like those of Davids at
