I recently bought the 65 litre with the alcoengine reflux.
I cant adjust the power through any controller for the 15 amp 65 litre boiler - but i can turn off elements to stop the vapour escaping through the top.
On my boiler, it has a 500w, 1000w and 2000w heating elements.
When running a smaller wash for the first time in the still, once the boiler got to temperature i turned off the 2000w element and everything worked very well.
On my next run with more in the boiler (approx 55 litre) I attempted to run the still at 2500w, and ended up with vapour escaping out the top.
I now only run a full boiler at max 2000w and everything is happy again.
I went digging through the information available (at Keg Land web site) and found that the alcoengine reflux should not be run at above 1900w (found out too late :crying-blue: ), But it does still seem to work running at 2000w - but I certainly must turn off the other elements or i will risk big problems.
From what i've read (and yes, i'm very new still too) is the 2500w 35 litre boiler you can turn down the power, so it may be that once the boiler temperature reaches above the 85 deg, start to turn down the power on the boiler for the final stages of heating up. (note: i'm talking about boiler temp, not column temp).
By the time the boiler temp is up at 98 degrees, i'm using starting to get tails in my collection jars.
I also watch the column temp carefully (cant remember the figures from the top of my head, only used it 3 times properly so far) - but i'm more careful now about the drip rate into my collection jars. Once the drip rate slow down, I'm almost certain I'm into tails. Then comes the smell and taste tests to be sure.
But, congratulations on your purchase and I hope you have a lot of enjoyment playing with it, and learning its quirks and what works well for you.
Dang - after i posted the above I read Stig's reply ....
So, Stig said it in much fewer words. I obviously talk too much.
