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 heater 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. This differential can be increased by using an insulating cover. To decrease the temperature differential, stick only a portion of the heater to the fermenter.
For greater results, we recommend a temp controller and carboy thermal well for the ultimate in fermentation temperature contol. 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.
