Did the job - but has limitations
I used this for my first batch of home brew. I was concerned about keeping the proper fermentation temp during the winter in my "oldish" house here in Seattle. I did not want to leave the heat on in the house during the day while at work- so I bought this to provide heat and regulate the fermentation temp.

I think the main limitation is it did not provide enough heat when I was fermenting in my basement. My basement was 50-55F and I could not get my ferm temps to 65F with this unit. I even tried insulating around the heater and ferm bucket- but that only helped a bit. The unit only provide 35 watts of power - so that is not enough (especially if you think of it as a 35 watt lightbulb trying to heat the fermenter).

Second limitation, it does not wrap completely around a std 5 gallon bucket fermenter - the unit is not long enough.

But, once I moved the fermentation up stairs to the "warmer" part of the house - it worked fine. The upstairs was 55-60F degrees during the day and the unit worked really well. BTW, I paired it to ThermoStar® Dual-Mode Digital Temperature Controller and both worked quite well.

So- yes I would recommend this unit - but with the limits I have noted.

Cheers

Controlled temp equals better beer!
I love the fermentation heater and about to buy a third. I wanted to respond the guy who is in Seattle who gave this 3 stars. I too am in Seattle and we had a bad cold spell where my basement was 50 degrees. This heater easily gets my brew up to 70. I put electrical take all around the edges of the heat wrap and this helps keep the heat in. I also like that it doesn't wrap all the way around because my thermometer is stuck to the middle of the carboy, the sticker thermometer is also there as are one gallon hash marks. I don't want to cover these up. Love this thing. I couple it with the ThermoStar. Love them!

Exactly what I expected.
Did it's job, easy to use, doesn't take up much space. Worth the money when you are fermenting in a cold apartment.

Works Great
I built a "Son of Fermentation Chiller" and an STC-1000 temp controller, but needed something to keep my plactic bucket fermenter warm during the cooler months. This worked perfectly and I have had no problems. You do need electrical tape to stick it to your fermentor, but other than that you plug it in to your temp controller and let it run! Awesome 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!!

KK - pretty good product
I bought mine for the cooler months. Mash works better at 80+. This let me get an early start this year. Controllers are little expensive and each Fermotemp needs it's own. I plugged all 3 of mine into a power strip with a $5 lamp timer instead so I could turn on/off every 1/2 hr if I want. Works fine this way on every 1 of 4 hrs. Could have been a little wider and longer as they barely fit the 6.5 gal bigmouth with the ripples and dents in the bubbler (ripples and dents in bubbler also not a good idea/smooth is better). All in all getting the job done.

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.
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?

BEST ANSWER: These products are not compatable, a heat wrap should never be covered.
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.
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.
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.
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.
