I have built an addon onto my shed, originally for bikes, now as a brew shed. I'm going to build a stand for my two 10g coolers and BC burner. I have always had my two Chuggers and plate chiller on a portable stand, wired with switches, that I took in the house and brought out only when I brewed. I'd like a more built-in design, and am thinking of just taking the chiller away to the house and leaving the pumps. I have the heads oriented vertically, so they drain anytime I'm done with them. If I build them into the stand, do any of you see any problem with leaving them out in the winter? With the head vertical, there shouldn't be any water left in them to freeze and damage the head, right?
