Description

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.

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.

Can I put this on a stainless steal fermenter?

Cainon b on Jan 3, 2021

BEST ANSWER: I use mine on a 7 gal stainless steel fermenter and am VERY happy with it. I brew in my garage and with an inkbird controller, this heater will keep my beer at 68 F even when the garage temp is 30 F. I use black electrical tape to hold it against the fermenter. To be fair, I do wrap the fermenter with insulation right over the heater.

Sure. I use in glass carboy, so see no reason you can’t use with stainless steel. Note, you need to tape it onto fermenting vessel to secure in place. Recommend Gorilla Tape or something strong enough to hold weight. Ok to cover up when on as well to insulate.

How much can you raise the temperature with the sleeve added?

Jeffrey C on Mar 30, 2022

BEST ANSWER: I wrapped a glass fermenter with this heater and then covered everything with towels. It fermented a beer with Kveik yeast at close to 100°F. It might be able to go higher, but it seemed like that was about the limit. I used a temperature controller to maintain that temperature, so I don't know for sure.

Holds temperature well.

It seems to work well enough. The only issue I have is that it doesn't come with anything to hold it on the vessel. Since it doesn't wrap all the way around it could use some sort of strap.

Works well, little flimsy

Works perfectly with our new bung and temp controller and thermowell. We have a much better control of our fermentation temperature. Would purchase again, but it does seem a little flimsy so I’m not sure how long it will last. We currently have it keeping our Lambic Ale at then proper fermentation temperature.

I am a bit disappointed with the heater, but it is my own fault. I assumed the heater would be thermostaticly controlled, it is not. Apartrom that it works great, I just have to keep an eye on it.
