Fermentation Heater Carboy Warmer - Kombucha Heating Wrap with Thermostat for Temperature Control - Electric Heat Pad Belt for Home Fermenting & Brewing - Fits Most Fermenter Vessels 2 to 8 Gallons

This product works better than other more pricey setups! Now that I have used this product for just over a year including the end of last winter and the beginning of this one I feel it is an appropriate time to offer a review. I have two different warming wrap setups for brewing beer. I have an ink bird and a very common warming wrap available through Northern Brewer. Ultimately that setup costs between 30 and $50 more than this. I just checked on the operation of both and this is outperforming it easily. Unlike the other setup this actually keeps the temperature within a degree or two of the set point. The other allows it to fluctuate almost 5°, which with yeast has a large effect on it. When powered on at first to bring the fermenter up to temperature it is noticeably warmer than the other allowing for a faster adjustment to the Target temp. I use this in combination with a Carboy wrap to help hold the heat in and the brewery typically is around 45° and this holds at the 69° set point with little effort. Would definitely recommend this product and when I decide to purchase another setup it will be this over any other option! Happy Brewing!

I use it for fermenting my Kveik Beers and it's been great! Can keep temperatures as high as I want. Fits my two different stainless 6.5 gallon fermenters easily.

My 2 gal. glass kombucha vessel is small enough to place in my house in a combined water heater and HVAC closet to help keep temperature of fermenting liquid close to the ideal 78-81 degrees for brewing. However, that vessel is now being used by my SCOBY hotel. So I bought a 4.7 gal. hammered glass vessel with nowhere in the house to keep it at proper brewing temp since the weather turned "cold" in late fall/early winter here in Southern California. The vessel is too large to fit in the HVAC/water heater closet. I turn the thermostat to our central HVAC down at night to at least 68, then up to 74 or 75 degrees during the day/evening. The is not warm enough to raise the temperature of my fermenting kombucha, which has been consistently 68-71 degrees day and night no matter how warm I heat the house to (as high as 76-77, but normally 74-75. Wrapping a heavy blanket around the vessel seemed to only keep the ambient temperature of the room out/away from the vessel. So I bought this Kenley Fermentation Carboy Heater with Thermostat - Kombucha Heating Kit and hooked it up yesterday evening. What a Godsend! I have the thermostat set at 80 degrees and while the temp on the thermostat fluctuates 1 to 1.5 to 2 degrees, it's keeping the adhesive strip thermometer on the outside of the glass in a very acceptable range of 78-80 degrees! Just what I wanted/needed. This is worth every penny I paid. My SCOBY has "taken off" in less than 24 hours!

Heater works great! It brings mash up to temperature slowly then holds steady temperature throughout fermentation process. Fits 5 gallon bucket very well. Easy to attach to bucket with provided elastic straps

I was hesitant to try this, but am pretty happy with it. I am considering getting another one. I ferment beer and wine in my garage in Alaska, and to save heating costs I keep the heat low in my garage. This has really helped me keep carboy temps consistent. The temperature controller seems to lag a bit on shutting off the heat, I suggest setting it about 2 degrees cooler than you want. Yesterday I put an old fleece jacket over the carboy with the heater and sensor under it, this seems to do better, but the carboy temp is still a degree or two over what I have set. This seems consistent and is easy to compensate for. The only real complaint I have is the rubber bands that came with it to wrap around and secure the heater to a carboy sucked and I threw them away almost immediately. I have been using duct take to keep the heater on a carboy.

I absolutely love this using it to keep my scoby worm and cozy and this is doing the job. Love the extra large size.

I love this heater. I wish they still sold them.

works great
