Keep your yeast or ML happy and your ferment warm during those cold winter months with this flexible heater made by Fermentap. Using tape to adhere, this flexible heating wrap 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 wine 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 contolled by sticking either the entire wrap or a portion of the wrap to the fermenter. In an open evironment 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 precise results, we recommend using our temp controller (FE610) and carboy thermowell (FE612) for the ultimate in fermentation temperature contol.

For heating small stainless variable volume fermenters and barrels up to 30 gallons a single FermWrap! works great. For volumes of 60 gallons or more, we recommend using two or more FermWraps (we do this in our winery Olin Wines all the time!).

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

BEST ANSWER: I use one with my fermentasaurus without any problems.
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.
When using this with the Neoprene sleeve does it go inside or outside the sleeve?
Ryan Heideman on Apr 12, 2020
BEST ANSWER: You will get the most efficient use of your heater by putting it directly onto your fermenter and inside the neoprene sleeve.
Will this work with the 7.5 gallon anvil bucket fermenter? Cheers
Jeff Shoemaker on Jan 24, 2020
BEST ANSWER: I have a 7 gallon BrewBucket, so I can’t see why it wouldn’t work on the Anvil. I wrap it around the fermenter and use masking tape to tape the edges to the fermenter.
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.
How do you use the FermWrap with the Fermzilla and the Insulating Jacket? I thought the Fermzilla couldn't use a heater because it's plastic.

FermZilla Conical Fermenter - 7.1 gal. / 27 L
BEST ANSWER: I would not use the FermWrap. It is too wide to fit the FermZilla and it is rated at 40 watt. Kegland suggests under 30 watt is safe. I used 4" wide reptile heat wrap for my FermZilla. That is 22 watts and I have had no problems.

The FermWrap™ Heater
Worked well, paired with an Inkbird controller I was able to keep my cider fermenting nicely.

it works
I used it for a Belgian Strong Ale that needed warmer temperatures for fermentation up to 80 F (27 C) and it did it efficiently. I used a neoprene jacket from my Brewzilla setup as insulation

Thermal wrap heating wrap
The thermal heating wrap works fantastic with my Inkbird temperature controller. I now have two of them and can control the temperature at all times within one degree on car it’s and or kegs during fermentation.

Some guidance or instruction needed
I purchased a FermWrap to help ferment the Hornindal Kveik yeast. I had no idea how warm it would get, but the yeast likes it up to 98 so I thought I was safe. 16 hrs later, the temp on the outside of the carboy was 125. I thought I had killed the yeast. Thankfully, that yeast is a monster and started to ferment again once I cooled it down and I think it may turn out OK. Some simple instructions would be helpful

This heater works well but unfortunately the plastic wrap is very brittle. It is already starting to crack where the electric cord connects.

FermWrap + mini fridge is a win
Does as advertised. No issues yet. Need to purchase a controller with it.

Outside temp is 55F, heated the minifridge up to 72F no problem.

Works exceptionally well.
This has changed my fermentation process for the better. with this FermWrap and immersion thermometer (in a thermowell) I am able to keep my wort temp within a degree of optimal desired fermenting temperature.

This thing is bomb. Taped the ends onto my carboy, wrapped in towel in my fermentation chamber, and raised 20 degrees no problem. Haven’t tried to go higher yet.
