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!

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.

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.

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.
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.
