I am contemplating purchasing a SS Unitank (either the 14 gallon or half bbl). My brewing system is limited most by the fermentation vessels I use right now, as I still use carboys (uggh). Does anyone have experience with the smaller SS unitanks? I am particularly interested in hearing about integrating a chilling system and what people have done in this regard. While I would love to purchase a glycol chiller, this is definitely a while off. Has anyone used a temperature controller with a more rudimentary chilling system?
