The Brewer’s Edge Fermentation Space Heater is specially designed for use with the Controller II (or other precision heating thermostat) to heat the inside of a refrigerator or other small (25 cubic foot or less) insulated area. This flexible 1/8” thick vinyl heater features an self-adhesive back, so it can be permanently mounted on an interior wall of a refrigerator, without taking up any usable space in the refrigerator. During the Summer, just leave it affixed to the refrigerator without plugging it in.
The Fermentation Space Heater draws only 25 watts of power, yet is powerful enough to keep a small enclosed insulated area (25 cubic feet or less) 20° warmer than the surrounding air. This means you can, with the heater plugged into the Controller II, precisely heat a closed refrigerator, freezer, or other small insulated area. Even if your refrigerator is in an unheated garage that gets down to 42°F. during the winter, you can still brew an ale that requires a 60° - 65° fermentation temperature. This heater is not an immersion heater, and is not intended to be installed on or under a fermenter. 8” by 12” in diameter, with a 6’ power cord.
