Description

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. 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 FermWrap to the fermenter.

With 40 watts of heat spread over almost two square feet it provides gentle even heating. Draws 40 watts. 115V.

For more precise results, we recommend 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.

This is the original FermWrap(TM) manufactured and wired by Fermentap in the USA. Be aware there are now some imitations being sold coming from China that have the electrical wire connections, where the cord meets the heat wrap, sealed with silicone. The FermWrap uses the proper electrical clip connections which are safer and will last longer.

Item does not include carboy as pictured.

Can this be used on plastic Fermontser 7gal?
Timothy Chilcoat on Jan 27, 2018
BEST ANSWER: Yes, I have also used it on my Spidel 30 L ( 7.9 Gal). And works excellent. I did use a beach towel to wrap around my plastic Spide 30 L as temps were dropping down into the 30 s in my shop.
Can this be used on the stainless steel brewbucket fermenter?
John Lilli on Apr 26, 2018
BEST ANSWER: On the outside of the fermenter yes. Works great with a bit of extra insulation around it for improved heat retention.

Carboy Heater Blanket
Since my wine cellar is not temp controlled, it is 55 deg right now as it is winter in the Sierra foothills. With this carboy heater plugged directly into a plug, the car will only get up to 68 deg.
I would like ti to get a little hotter, even if I needed a controller to reduce it some.

It does the trick.
I was making a Saison that required higher temperatures. It did the trick. It's cheaper and takes up less room than building a fermentation chamber. I did wrap the carboy in a jacket but was able to raise temps into the 90s.

the design is perfect for heating large vessels
I do have a couple of brew belts but bought the fermwrap because I liked the idea of a much larger surface area contacting my fermenter. I use 60 liter Speidel fermenters and the fermwrap does a nice job of maintaining temperature as managed by Johnson controls temp controllers. I normally wrap a blanket around the fermenter, and loosen/remove the blanket during peak fermentation when the yeast is generating a lot of heat.

The construction seems a little fragile as compared to the brew belts, but I haven't had any problem so far. I am careful with it and hang it vertically when it's not being used.

Great for MLF.
This carboy heater works very well. I typically use them for MLF. It should be used in conjunction with a temperature controller.

Works great with the inkbird controler. First lager with the system has been a breeze with this unit in a small freezer.

Mine didn’t work
It never worked. I bought it for a carboy but I graduated to a conical fermenter. I was trying to use it to warm up the fermenter a little in my refrigerator fermention chamber. It never got even slightly warm. I may have gotten a bad one, but I wouldn’t recommend it.

Works well
Easily maintains a 6 gallon batch 20+ degrees F above ambient, with minimal insulation. Nice size for wrapping around my PET carboys.
