Keep your yeast happy and your ferment warm during those cold winter months with this flexible heater wrap! Unlike those old heater belts, the FermWrap covers a wide area of your carboy or fermentation vessel, promoting an even heat distribution (11" tall x 25" wide.). Using tape to adhere, the FermWrap can be attached directly to your fermenter, or can be used to heat the space in a box (or refrigerator) that the fermenter is in. Depending on your configuration and insulation, you can increase the temperature of your ferment from 5-20 degrees Fahrenheit.
With 40 watts of heat spread over almost two square feet it provides gentle even heating. Draws 40 watts. 115V.
For greater results, use a temp controller and carboy thermowell for the ultimate in fermentation temperature control. Or for the best control, use the dual stage control and carboy thermowell, as well as a refrigerator, to control both the high and low temps.
