Re: design help
- I stand to be corrected here but i think the general concensus on
aluminium boilers is "only if you have no other alternative"! A
couple of posts have mentioned metallic tastes and corrosion, and
IMHO it just isn't worth it for something you're going to put in
your mouth. I used an ex-army stainless cook pot for my boiler which
i bought for about £20 ($30). Two litres of brand name spirits from
a supermarket would cost about the same, and my still will produce 8-
10 litres per batch and i've run 6 or 7 batches so far. It pays for
The boiler power will dictate the size of column you have to use if
you can't turn it down. The files and calculators on here will give
you a good idea of what size column will cope with what power input
from the boiler. I did it the other way round, in that i had a
certain size column and had to find a power source big enough to run
Hope that helps.
