My fermentation chamber
that thing rocks! What do you have cooling it?
I was wondering the same thing, I'd consider building something like this also. Is it relatively cheap to build?
I mill with a barley crusher set at .035", mash with an orange rubbermaid 10 gallon cooler. Heat mash water in a stainless steel 7 gallon pot, boil in a Bayou classic 11 gallon kettle, ferment in 6.5 gallon glass carboys.
I use Iowa City tap water, treat it with Camden for mash and sparge. It's decent water, relatively hard, which I find is good for brewing most ales. I prefer to crush the grains the night before I brew, get up and start the mash water at around 10am if I'm not hung over and usually get done brewing in 4-5 hours.
I have an old burner that my stepdad gave me, not sure what the BTU output of it is, but it works pretty well. Usually get around 5 boils out of a 15lb tank.
