I have a small one-room studio. No room for another fridge or chest freezer. Also, I think a water bath is a lot better at controlling temps inside the fermenter anyway. This turned out to be simple but effective:
Better-bottle fermenter sitting in a water bath inside of a 10G Home Depot Cooler. Two stage controller controls an Ice Probe for cooling and an aquarium heater for heating.
The spigot hole was enlarged and an Ice Probe is inserted there (no leaks yet). Inside is an aquarium heater, and little $13 fountain pump to circulate the water bath (turns out it really stratifies if you don't have that). And of course the controller sensor.
Results:
- Heating was no problem in the winter. Not sure what the limit is for a cooling differential, but the second pic is with an active fermentation going on a hot day (82 out/65 in).
- Temp inside the better bottle seems to not be more than 1F off than the water bath temp, even during an active fermentation.
- Small, quiet, great for a small studio apt. Looks ok if you turn it around and try to cover up the ugly home-depot-orange
