Perfect Review by Rob

A few pieces of tape and this thing does a great job. I fashioned an easy insulator from the box NB used to send a couple of recipes in. Taped a towel around the inside of the box on 3 sides. It takes about an hour to move from 68 to 73. Nice and easy! (Posted on 5/2/14)
Harness the cold Review by John
Rating
I've used this along with the temp control thermostat for three beers now and these two items are one of the best purchases I have made for the quality of my beers. No more carrying carboys up the stairs. No more futzing with the house thermostat or placing thermometers all over to find that just right spot. Just find the coldest part of your home, and you're set - that is until summer comes. It is perhaps the most valuable tool I have during the cold months to help me make great beers, and since it is cold here 10 months of the year, I'm set.
My carboy does remind me a bit of Frakenstien when wired up: "it's alive! alive!" (cue lightning). (Posted on 2/17/14)
A life (beer) saver Review by Andrew
Rating
I never thought I would need this product because, although I live in Wisconsin, my temperature controlled fermentation refrigerator is in my heated basement. However, on my last brew day of the year, my water pipe in my basement froze and exploded. After the plumber fixed it, I needed to keep a door open to ensure the space where the pipe was located stayed warm. In turn, this opened my basement up to major heat loss, bringing the ambient temperature down below my desired fermentation range.

In a hurry, I picked one of these, hooked it up to my Johnson Digital Temp Controller, and set it to heat. In no time, my fermentation temp was where I needed it, so I aerated and pitched, and the EFH kept my beer at a steady temp the entire duration of fermentation. (A benefit of keeping it in a fridge is that the heat is trapped, so the temp doesn't swing/drop as often.)

After all that, my Belgian Blonde turned out great, and I owe it all to this product. Thanks, Northern Brewer! (Posted on 1/7/14)
Basement too cold Review by CJ

Gave as a gift for someone using a fish tank heater & cooler set-up. Seems to be a great option for someone who deals with cold temps and needs to increase fermentation temps. (Posted on 1/4/14)

Great product, currently keeping my fridge at a good brewing temperature in my sub 32 deg F garage! Works well with the Johnson Controls electronic temperature controller. (Posted on 12/16/13)
Excellent addition Review by Mark

This was an excellent purchase, great for those cooler months where you need just a bit of a kick to keep things going. I paired this with a thermowell purchased at ETC online for $12 and the Johnson A419 controller and it works great. Rated 4 stars because it could use a better mode of attachment to a carboy than electrical tape... Will work on that one (Posted on 12/7/13)

Works great in a fermentation chamber Review by Barking Dog Beer

I put this in a small fridge with a better bottle carboy. No need to even wrap the carboy, since it is in an enclosed space. I control the temp with a Johnson controller. (Posted on 12/4/13)

Bought this along with the Johnson temperature controller and they work perfect together. Kept my temp within 2 degrees the whole fermentation in a 60 degree garage. Definitely worth the money. (Posted on 12/2/13)

To easy Review by Colin

I was hesitant about this product.

I've put this heating wrap in a 7.0 cubic ft. Freezer attached to the Johnson blue Digital Temp Controller (also sold at Northern Brewer) - set to heat (jumper adjustment). I set the temp controller to heat to 69 degrees with a 1 degree difference and it works like a charm. I've two thermometers in the freezer I've been using to check for three days and it is right on the money. The temperature ranges from 68-70 degrees.

My freezer is located in a drafty garage and this has been an easy way to keep my two 6.5 gallon carboys at 68-70 degrees. With the outside temperature ranging from 50 - 65 degrees…. Happy Yeast = Good Beer.

Really Works Review by Merlin
Rating
our basement tends to stay around 68 to 70 degrees in the cooler weather and this heater raised the primary and secondary fermentation process a good 5 to 7 degrees - allowing the wine to ferment completely. Used it with a timer to turn on and off in 4 hour increments. Works great! (Posted on 11/3/13)
Solid Fermentation Control Review by Philosofool
Rating
Proper temperature control is the most under-appreciated part of homebrewing. We think about everything until the yeast hit the fermentor, then we forget about it until it is done.

I decided to change that for myself and invested in this and a DIY temperature controller. My double IPA is on the back porch, where it's freezing at night and 65 in the day, but my IPA is sitting at a nice 68 degrees. The warmer doesn't feel hot--good, because you don't want to melt plastic or shatter glass!--but it warms the beer about one degree per ten minutes while it's on.

My only complaint it that it requires a little tape to put it on the fermenter. Why not have a velcro or similar strap included? (Posted on 10/24/13)

Fermentation control is the most under-appreciated aspect of good brewing. We think about everything that happens until we pitch the yeast, and then we forget about it until it's done.

I decided that I needed to change that for myself and invested a little cash in this and a DIY temperature controller with parts from China. My double IPA is on the porch, where temps run from 30 to 65 degrees this time of year, but my beer sits at a perfect 68 degrees, 24 hours a day. This device works exactly as advertised, and warms beer through a 0.3 degree temperature differential (with a regulator, no included) in about 20 minutes. It doesn't feel hot, which is good--you don't want to melt your plastic or shatter your glass!--but it is warming your beer.

My only problem with this is that it requires a little tape to affix the warmer to the fermenter--could we have a built in velcro or similar strap? It's a minor flaw, but to me Five Stars means "flawless." (Posted on 10/24/13)

Great price for a great improvement Review by Joey

I also paired this with the Digital Temperature Controller. I bought a $40 used fridge and can used the temperature controller to cool the beer in the fridge during the summer months, and heat the beer (still in the fridge for insulation) during winter months. Plug and play, no problems. Temperature control is such an important part of brewing, spending the ~$150 for a fridge, temperature control, and this heater is definitely worth the money. Before I invested in this setup, I had already lost two batches to unhappy yeast due to suboptimal temperatures. Get yourself a temperature control system from the start. (Posted on 10/3/13)

I now own four of these units. Flawless performance to lock in your temp. I even dropped a glass carboy and my heater was unscathed! They do their job in a subtle way. Don't expect them to be as hot as a heating pad. (Posted on 7/11/13)
Right on target! Review by BH

Bought unit along with Digital Temperature Controller (SKU: 40090) to maintain a consistent temp on a batch of Roggenbier currently in our secondary.

Simple, effective and relatively cheap solution to keeping the brew warm on cold Minnesota winter days.

Can't imagine using the heater without the temp controller, but it was worth the investment! (Posted on 12/13/12)
Works great with one exception Review by Chris
Rating
I have two of these that I wrap to my glass carboy, use the probe carboy stopper, and digital temp control for laser precision temp control. After a couple of uses and rubbing the sides as I slide it down into my converted chest freezer kegerator, the two clamps that provide electricity have come off and while they easily reattach, they don't always work until I mess with them to ensure a solid connection.
If you use this in a standard fridge or cold room where you won't rub up against things, you'll be fine. Any sort of navigating in a kegerator with kegs and other stuff can cause problems. (Posted on 11/18/11)
Works like a charm Review by John
Rating
When I received mine, I was highly sceptical of it. I plugged it in and it barely felt warm to my hand. However, I set it up with a 5 gallon carboy of cold water in a 55 degree cellar and overnight it brought the temp. up to 75+ degrees. I have since used it in brewing and it keeps the temperature within about 1 degree Fahrenheit of the optimal fermentation temperature. You really need the electronic temperature controller, which is a bit confusing to set up, but once done, this is a great system. (Posted on 11/17/11)

Use this on buckets and carboys in my basement. Basement temp is usually around 55 and it has no trouble bringing the temp up to 70+. Would definitely advise using it with the temp controller, otherwise it's lots of plugging and unplugging it (Posted on 2/15/11)

Using this with a Johnson digital temp controller and it's enabled me to return to brewing in the winter months. My house is drafty, and I run the heat rather low. This belt works perfect on plastic fermenting buckets, same for glass carboys, just be sure to check and tape it on well. (Posted on 1/17/11)

You can buy the same heater tape in any length (and also in 3" width) from a reptile/pet supply store. I use the material myself and find it to be excellent. Buyers should know that you can customize this material in more ways that this product suggests. (Posted on 1/6/11)
WORTH IT! Review by Jason

I typically don't write reviews, but I must say that even though these heaters feel flimsy, they do the job! tape them on with black electrical tape and you should be fine. My basement runs 53-57 in the winter and with the johnson temp controller I can keep my fermentation at 70 with ease. They heat up slowly which is okay, but once at temp- MONEY! Especially if you use the temp controller! I even use 1/2 gallon jugs for yeast starters and 1 of these heaters wrap neatly around 2 of them to help keep the yeast happy and active. I did buy the thermowell from williams brewing since they advertised #10 stopper and fits johnson controller (which meant an additional cost in shipping ) I bought two heaters and use one controller plugged into a power strip to run two heaters and have produced tasty beers without any problems. cheers (Posted on 11/23/10)

The heaters work great in a fridge. I insulate the outside of the heaters and keep the fridge around 40deg. I tape my probe to the outside of the carboy. It is good that the heater doesnt completely wrap around the carboy or the heater could skew the probes temps. (Posted on 7/5/10)
