Another lesson you'll learn is that the thermo is really just a guide. Learn to read your output or the drip if you will, you'll like the end result much better.

#1 As you go up (SLOWLY OR LOW HEAT) through the temp range you will learn when to start turning down the heat so you can catch it at that just right point and then set your drip right there. Not sure if you use gas or elec. but either way you still have to set the heat at the just right setting to collect. And as you go through the run your temp will continue to go up, that's normal, so monitor closely, no napping whilst stillin.

#2 You'll find that water will indeed take more heat to vaporize than your wash. And as you learn you don't want to boil as hard as you cook your wash like you did when you ran just water.

#3 Remember, when you run mash use the drip or little stream to judge weather your heat is set right. You can work the thermo into the equation at some point as you eyeball the drip and learn what temp the drip started at.

#4 Use a bigger container to hold the condenser water and then add the ice as you go. Like a big cooler of water and add a scoop of ice to maintain the water on the cooler side, not necessarily cold but cool enough to cool down the steam to condense back to a liquid. After you make a few runs you'll find out what works and what doesn't.

Hope this helps but still keep reading this site and others cause there's lots to learn about running your unit and making something that's worth drinking.

I suppose someone could make that little still work but go through Tech Support or Building a Still on this site you can find lots pics there to decide which to buy or build. I used a 7 gallon beer keg but you should def check out Brewhaus units too. Good luck with which ever you choose and most probably the folks here can help you make whatever you pick work.
