“The FermWrap heater is used to gently heat fermentations. Use tape to adhere this flexible heating wrap directly to your fermenter. Depending on your configuration and insulation, you can increase the temperature of your ferment from 5-20 degrees Fahrenheit. If using carboy or bucket you can attach directly using tape (as seen in photo above.) We recommend electrical tape as it sticks and unsticks the easiest. Heating can be controlled by sticking either the entire wrap or a portion of the wrap to the fermenter. In an unenclosed environment we see a heating differential between carboy and ambient of 10-15 degrees. This differential can be increased by using our carboy bag to insulate a carboy (this has been tested.) To decrease the temperature differential, stick only a portion of the heating wrap to the fermenter. For great results, we recommend a temp controller and carboy thermal well for the ultimate in fermentation temperature control. Or for the best control, use the dual stage control and carboy thermal well, as well as a refrigerator, to control both the high and low temps. You can tape the heater to the wall of the refrigerator as well. With 40 watts of heat spread over two square feet it provides gentle even heating. Draws 40 watts. 115 V.”


Use in conjunction with a temperature controller to dial in fermentation temps.
