Features

  • PERFECT TEMPS, PERFECT BREWS - Whether you're brewing kombucha, wine, mead or beer, the Kenley fermentation heater comes with a temperature controller that allows you to set and maintain the exact temperature you need for your brew. This ensures that you won't risk overheating or chilling your brew.
  • EASY TO USE - The Kenley kombucha heating wrap is flexible and easy to fit snugly against the carboy. The 32 x 11-inch film simply wraps around the fermenter and is secured with the elastic bands supplied. It fits most brewing vessels but is best suited for 2-6 gallon carboys to ensure even heating. The fermentation heater operates on 110V power and can be plugged directly into an electrical outlet or the temperature controller.
  • CUSTOMIZABLE TEMPERATURE - Set the temperature on the thermostat and the device will maintain it. The heater will only turn on when it detects a drop in temperature and will stop running as soon as the desired temperature is reached. You can submerge the probe inside the carboy or use the suction cup or tape to attach it.
  • WINTER-PROOF YOUR KOMBUCHA - The Kenley carboy heater can help you maintain a constant temperature and speed up the brewing process, saving you time and effort while creating more perfect batches. By keeping brews at a consistent temperature during fermentation, you can also prevent spoilage.
  • DURABLE AND LONG-LASTING: The Kenley carboy heater uses only the minimum energy required, unlike always-on systems, which helps keep your energy costs down. It's built to last, with a durable design that ensures it will be a valuable tool for any brewer for years to come.

  • Works
Great heater, worked to heat my brew in a 50F garage to 70F. Seems well made, hope it lasts a few years minimum.

  • Works great for keeping brewing kombucha at proper temp in cool/cold house at night in winter
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! ... show more

  • Works well
I've only used it once and worked as expected. Bought it to ferment beer with Kveik. I meant to pitch at 95F, but cooled the wort down to 85F. Set the heat wrap for 100F, at ambient temp of 70F. Took some time to go up 15 degrees to 100F, about 6 hours, which I suppose is a good thing because it heats gradually at a warm temperature and not at very high heat that may overshoot the target setting. Once at temperature it held well for 2 days, within 1 degree. I took away one start because the "Heating" light on the temperature controller does not work, doesn't turn on when the heating element is activated. I wasn't sure if I had programmed it correctly at first, but the outlet was activated and the heating mat was warm to the touch. I tested the controller outlet with a phone charger to make sure it was working properly, and it was. It's just the heating light indicator that is not functioning. Wished it worked, but I suppose it's not a huge deal as long as the controller is working properly. ... show more

  • Works as advertised
I have no complains what so ever for this heater. It's like "set it and forget it". I was checking temperatures inside the carboy and it is consistent with pre-set temperature. Nice product!

The first one I received did not work but the second one had no issues, I’m very happy with the purchase.

  • Suits my needs perfectly
I required a heating mat that I could wrap around a 3-gallon kombucha brewing vessel. The vessel is basically a glass cylinder with no tapering and a stainless steel spigot at the bottom. It's 15" tall and 29" around, so the 11"x32" mat size wraps around it with just a little overlap. It sits just above the spigot, but with a couple inches to spare on top for the rubber band that holds the cloth over the top in place. I will say that the rubber bands that came with the heater don't work for much besides storing the mat in a rolled position. I needed a much larger band to wrap around my container. Since this mat is designed for up to 8 gallons, I'm not really sure what they meant by using the included rubber bands to keep the heater wrapped around the vessel. The included bands would struggle with a gallon jug, and the mat is far too large for that size. Another point to note is that the probe should be placed UNDER the heating mat. I attached the probe via the suction cup a position just below the mat, and secured it (to ensure direct contact) with a small piece of masking tape. The thermostat registered 80 degrees, but a check of the liquid temperature indicated 100 degrees. Yikes! I repositioned the probe to underneath the heating mat and let the temperature settle, and that resulted in a very accurate temperature of the liquid/thermostat. I set the thermostat to 78 degrees. When it dips a tenth of a degree below 78, the heater kicks on. When the temp reaches 79, the heater turns off, but the temperature continues to rise to mid-tenth degrees before it starts to drop back, keeping my kombucha in that 78-80 degree sweet spot. I'm very happy with this heater so far. The mat is thin, not at all bulky, but sturdy. The cords are heavy-duty and of sufficient length. The thermostat is easy to use and very accurate (provided it's place correctly, lol). It's definitely a critical component of my continuous brew kombucha setup. ... show more

  • Works way better than those small seed mats
I like the thermostat, because I don't want to babysit my batches, or cook my SCOBY by accident. This is really thin and nice, compared to the bulkier, hotpad-like mats that are also used for seed starting; it's easy to wrap around a jar with a little overlap. I have about 3 inches of overlap with my 2-gallon container. It's really nice, and takes a lot of the effort and dinking away. ... show more
