Do any of you have experience with this tool?
What must the room temperature be for the brew belt to maintain a constant temperature?
I put it on my primary last night. It jumpstarted my stalled fermentation, but the temp of my wort (measured with the "sticky thermometer" on the outside of the fermenter) kept on rising . . . I unplugged it when the temp reached 78 degrees. The room temperature was around 65-68 degrees. Supposedly, the belt will maintain a constant temp around 75 degrees, but I imagine the room temp must be pretty cool to keep the brew belt from overheating the wort.
