I just set up a fermentation chamber in a chest freezer. I only have a single stage temp controller, and I was running a fermwrap with it. The ambient in my basement was 59 and I had the controller set at 61. What I didn't account for was the heat generated by my muffin fan. I left the set up overnight and came back to find the fermenter at 80 degrees in there. Fermentation was almost over, so that wasn't accounting for much if any of that heat. This fan was generating enough heat to raise the temp in there by over 20 degrees, which really surprised me. Just made the think about the fan (an identical one) that I run 24/7 in my keezer. If it is generating that much heat within the keezer, that must be making my freezer run a lot more. Thoughts?
