Used it once. Plugged into a regular dimmer circuit and worked great. Able to keep it just where wanted the temp to be. The electrical tape to hold it to the plastic fermenter worked marvels.

Works great in my cellar. I have yet to try it in my attached garage where it gets considerably cooler.

Great investment in my home brewery!
Works just as described. And I also got the Thermostar temperature regulator. It is a great investment in my home brewery.

Warm the wine
My basement is very cool and the wine just stays at low 60. After we put the heater on set the temp for 72 everything went a lot better

My Fermo Temp rap works very well, but I will have to get the temperature control for it. I also use it for my Kombucha.

Just About Perfect
The FermoTemp works like a charm to keep my 6.5 gallon Big Mouth Bubbler at the control temperature. The only deficiency is the need to affix it to the bubbler using electrical tape. Some sort of supplied fastener is all that's missing from this product.

First Fermentation with Temp Control
I decided to purchase the heater and ThermoStar digital control to better monitor my fermentation temps, which typically run cool due my local climate and location of my fermentation room. So far, it has kept the first batch in a very tight 68-70 degree range for 2 weeks which is optimal for the American Ale yeast I am using on a dry stout for Christmas this year. Yet another step forward to improving my beer!!

What is the nominal temperature this product outputs. Can I simply unplug it if it gets too warm?
A shopper on Dec 7, 2016
BEST ANSWER: There is no good answer. I bought the ThermoStar Dual-Mode Temperature Controller to mitigate having the fermentation liquid getting over heated. I checked my temperature strip on the outside of the carboy each day to ensure stable temp. The temperature sensor can be placed into the liquid if you have the Big Mouth Bubbler with dual port access or you can leave it out where it is sensing the room temperature. My fermentation area in the winter is about 52 F so I set the controller around 63 and the heat wrap kept the fermentation liquid around 72-74 F for ales.
Can this heater be used for kettle souring? 8 gallons in a 10 gallon kettle, insulation wrapped, looking to maintain about 90 degrees.
A shopper on Dec 12, 2016
BEST ANSWER: That pushes it but would be close. WE find it can reliably do 5 gallons at about 10-15 degrees above ambient room temperature.
Can this heater be used with a glass carboy?
A shopper on Mar 7, 2017
BEST ANSWER: Yes, assuming the temperature probe is attached to the side of the carboy, just as for a plastic carboy or bucket. The idea of actually inserting the probe into the wort didn't appeal to me. I upgraded to the 12" probe, but this proved impractical. I might use the shorter standard probe in a thermowell adaption to a plastic bucket (ie: drill a hole into the bucket at about the 2 gallon level, then screw in both halves of the thermowell to the inside and outside) but it works just fine attaching it to the outside of your fermentation vessel with electrical tape and insulating with a towel or something. Allow for a couple degrees difference since the probe is on the outside of the vessel.
Will this work ok on a plastic 7 gal fermentation bucket in a room with ambient temperature of 64 degrees F? If used with the Thermostar temp controller, could I tape the temp probe to the outside of the bucket and get ok results (bucket lid has a single small hole only for the air lock)?

BEST ANSWER: I've used in and open area in my basement. However I had the foam insert from some box that held the carboy almost perfectly about an inch off the floor. I then used masking tape to hold the sensor to the bottom of the carboy away from the heating element. I put another piece of foam under it to insulate the sensor from the floor at it is always pretty cool. I successfully used this set uo or five or six batches until I got a cheap 5 cu. ft. freezer and started making lagers. I use the heating side when it gets pretty cold here in Western New York to even maintain 38 degrees. I think if you just keep the sensor away for the heating element and maybe back it up with some insulation you should be good.
Will this work with a Fast Fermenter?

BEST ANSWER: Sorry, but I don't know. I haven't used a heater with my Fast Fermenter. I love my Fast Fermenter though. Well worth the money in the convenience it gives you alone.
would you be able to use this with a fermotemp heater or would you have a meltdown/ fire hazard in the making?

Catalyst 6.5 Gallon Tank Cover
Catalyst 6.5 Gallon Tank Cover
BEST ANSWER: These products are not compatable, a heat wrap should never be covered.
fermenter can't tell if it is heating. I set the Thermostar to 70F and have it wrapped around my glass 6 1/2 gallon fermenter. The digital readout never gets above 66 or so and the plastic film feels cold. Shouldn't it be at least warm?
A shopper on Jan 30, 2017
BEST ANSWER: The heater should feel warm and the thermostar should flip its light green for on. Ensure it is in heating mode and the temp probe is in contact with the fermentor. There is a delay and it may not switch one when the temp is close - try setting the probe against an ice pack to see if it flips on when it gets farther away from temp. This will let you test if it is working.
Can this be used with a glass 3 gallon carboy?
Cody B on Feb 12, 2018
BEST ANSWER: Yes. This fits both my 3- and 5-gallon glass carboys easily. Works like a charm.
Is it safe to use a carboy cover over the FermoTemp?

Carboy Parka for 5 gal carboy
Carboy Parka for 5 gal carboy
BEST ANSWER: That will be fine. It does not heat up to a level where it would be unsafe. With the cover on, the carboy will hold temp better, and so it should be able to use the heater less often to hold the temperature you have set it to maintain.
Can this be used on a 5-gallon Conelius Keg?
A shopper on Apr 12, 2017
BEST ANSWER: It would appear to me that it should work on a Conelius Keg. I have not used it on one, but have used it on a glass carboy, plastic big bubbler, and stainless conical fermenters. I would wrap it to make use of the most surface area, possibly wrapping it the long way if it fits or horizontaly and over lap if nessasary. I always try to put some sort of insulation such as small pocket bubble wrap or anything around the whole item to improve effecency. I always use my mine with a temperature controller. Generally my enviroment is around 53°-58° F and I am setting the temperature to 67°-72° F depending on need. Enter an answer to this question.
Looking at this picture, it looks like the picture is showing 2 heaters wrapped around the big bubbler even though only one electrical cord is showing. Is it showing 2 heaters or is this what the heater really looks like when attached to the fermentation vessel?
A shopper on May 30, 2017
BEST ANSWER: The picture is an accurate representation. It is one wrap with a seam between the two black parts there is just one cord. I have used this on the big bubbler, I have used it on a glass carboy, I have used it on stainless steel conical's and it works very well. I use it in about a 55 to 60° environment but I always try and put some insulation over it to make it more efficient.
Can this product be used for lagering temps?
A shopper on May 3, 2017
BEST ANSWER: This product is a heat generating warming device used to raise the temperature of the fermenting bucket or carboy. When you plug it in, it warms up. Works well in conjunction with an external thermostat controller. I assume you want to ferment your lagers at temps below room temp. This item will only allow you to increase temp above ambient temperatures. I use a chest freezer with an external thermostat to get 50-55 degrees for lagers.
Can I use fermo temp just in wall outlet and what temperature will I get that way?
A shopper on Oct 27, 2017
BEST ANSWER: You could plug it directly into a wall outlet, but I would not recommend it. I am sure it will get hotter than you want to ferment at. It has a limit to how hot it will get but I do not know the temperature. The highest temperature your wort would become would depend a lot on what the temperature of the room. I highly recommend plugging it into a thermal controller. There are some fairly inexpensive ones and you would have very precise temperature. I also like to insulate around the fermo temp and fermenter so the fermo temp does not have to come on as much. The room I ferment in is usually 55 to 60 degrees, and with insulation I have no problem maintaining my fermentation temperatures.
Is the product UL listed?
A shopper on Nov 3, 2017
BEST ANSWER: The electrical cord indicates (UL) E252926 SPT-2. There is nothing on the unit itself.
This unit clearly is labeled 110 V 50 Hz. Why?
Ken C on Jan 26, 2017
BEST ANSWER: The material is universally used between 110/120/220/240v - 50/60hz applications. The heating wrap as sold by us works on north american outlets running 110-120V 60hz
with the controller how high can the temperature go?...to boiling?
A shopper on Jan 18, 2017
BEST ANSWER: We recommend using this to heat 10-15 degrees above ambient temp. This is not meant to bring anything to a boil.
Is this large enough to work with the Catalyst Fermentation System?
A shopper on Jan 16, 2017
BEST ANSWER: The height of the Catalyst is about 10" so this is a bit to tall to fit.
