I just converted a cooler a few batches back, and all things considered it's working rather well. Getting a consistent 75%-80% efficiency, depending upon the amount/type of grain.
That aside, I noticed I'm losing a little bit of heat over the course of the mash. It'll hold constant for the first 30-40 minutes, then I'll lose about 1 to 2 degrees from that point until the end.
For example, if it's a 154*F mash, it'll hold steady for the first 30 minutes. Then it'll drop to 153*F, then down to 152 from about 15 minutes remaining until the end. Normal, or should I start looking into solutions?
