Nice setup by the way. I am curious how much you are able to drop the temperature with the bath you have going there? What is the room temp and BB temp?
The room temp is high 70's* to low 80's the swamp water was at 64-5*The brew area is in my basement as is my wood stove I have since rigged up a curtain to separate the room and last night it was 71* ambient on the brew side.
With the swamp coolers I can get the water down to 64* easily with ice additions my son works local and checks on them during his lunch. I have a lager in the lagering faze so I couldn't put this ale in there at 34*. The BB was at a steady 68* the whole time of fermentation. Once you get the 10 gallons or so of water and the beer to the right temp its pretty easy to maintain an even temp. I put a cap full or so of bleach in each bucket as the water will be sitting for 10-14 days it can get a little scuzzy if you don't.
I need to make some type of cabinet or cooling system for the conical so I can use it more often.
