The Brew Belt is the perfect solution for those who need a little extra heat to keep your fermentation at a warm enough temperature. This simple unit produces 15 watts of heat right where you want it. Instead of having to raise the temperature of the room, just attach the Brew Belt, plug it in, and you are good to go. The Brew Belt raises the temp about 10° F from the room's ambient temperature. If you want to be more exact with the temperature, hook it up to a thermostat controller.
Note: Will not fit a 7.9 gallon fermenter. NOT designed for wet areas, carboys, or to be immersed in liquid.
