## Questions & Answers

**Q: Is there a way to safely get the probe into the brew without contamination?**
A: Yes there's a way,  I made a very effective DYI thermowell with a piece of 3/8" x 20" pvc plumbing water faucet supply line by heating the straight end with a torch just to soften (not burn) and pinch the heated end quickly with a pair of locking pliers to crimp the end forming a water tight seal   under $2.00

**Q: How does this compare to a seedling mat for the same purpose?**
A: I think it would work well for many things. Mine are working well for keeping my brew warm. It would work for seedlings too or for keeping your chicks warm. Take note that the wiring where it attaches to the mat is a little bit vulnerable to breakage but if careful it will be fine. I use two of these and they work beautiful.

**Q: would this heat a small martha tent for fermentation adequately and safely?**
A: Maybe, the FermWrap is made to raise the temp 20 degrees of room temp.  It is not made to heat something in a cold environment.  It depends on the room temp.  I use it in the winter when my basement is in the 50's.  I can put it around my fermenter and drape some towels over it and it will easily keep it at 68 degrees.  Hope this helped.

**Q: Can this item be also used at 220V with the proper plug?**
A: No

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for keeping your kombucha at the right temperature
*by J***S on February 8, 2025*

We are using this for our kombucha with a temperature controller, and has been working perfectly!

### ⭐⭐⭐⭐⭐ Works great - can be used on plastic type fermenters
*by I***D on April 25, 2024*

I bought this for a more narrow plastic fermenter I occasionally use. I have the larger style with the Velcro but it’s too long for an average size fermenter. Besides having to use tape to attach this, it performed well on its first batch and did not hurt the plastic fermenter which is what I was worried about.

### ⭐⭐⭐⭐⭐ Works great, but isn't as big as it looks in the picture.
*by R***S on May 7, 2015*

It isn't apparent from the picture or description, but this doesn't fit around a standard 5 gallon carboy. In fact, it doesn't even go all the way around my 3 gallon carboy. I suspect the picture actually shows 2 of these, one on each side. However, it still heats well. I have one holding my 3 gal carboy at 70 degrees in a room that gets as cool as 64 degrees, and it isn't on all the time so I suspect it could easily heat it past that temperature.-----UPDATE:I ran a test and put 3.25 gal of water in a 5-gal plastic ale-pail, put this wrap around it, and let it run for a few hours. My water was at about 82F out of the tap when I started, and the ambient temp of the room was 69F. The single FermWrap was able to raise the temp of the water in the bucket to 98F before I called the test quits. Temp probe was submerged in the middle of the water. Pretty impressive!Based on this, I raised my rating to 5 star.
