5.0 / 5.06 ReviewsFermotemp is a win!Purchased the Fermotemp to help with diacetyl rests and ale fermentations. Works perfect. Temp easily raises to the top end of ale fermentation temps. I also purchased the Thermostar thermostat controler. Both together is a must to acheive a solid fermentation without the worry of esters and diacetyl ruinning your beer. Great purchase ????January 27, 2018Purchased
10 months agoKeeps a consistent temperatureFermented in a cool basement, set the batch on wood, wrapped the heater around the bucket and carboy, kept temperature at desired temperature the entire time.May 8, 2017Purchased

- Customer Q&A
Browse 7 questions Browse 7 questions and 19 answersWhat temperature does the Fermotemp sustain at without the Thermostar?BEST ANSWER: I believe that the temp fluxuates with the volume of liquid. I use 6 gal carboys and the temp stays between 74 and 76 degrees. Although I used one to warm water for a new kit which was 4 gallons and the temp was 80 degrees. They work well in my basement this time of year with the temps in the upper 30's and the lower 40's. Hope this answers your question.Can it be used on both glass and plastic bottle type fermenters ?BEST ANSWER: Yes; check the description for more details.Where do you put the temperature Probe when using the wrap on a caroby?BEST ANSWER: I actually use it for another purposes but I'd put it about 1/3 below the surface off to one side. If you set to he max temperature then put it nearer the top and closer to he side. And be consistent with placement to keep better control between batches.This fermentation heater can be used several times ?BEST ANSWER: Certainly, it is very durable. I use electric tape at the 4 corners. You should get one of the temperature thermostats too. Without one these will take your wort/must to 90+ degrees. I have 3 of these and 3 thermostats.Will the Fermotemp Electric Fermentation Heater work with this bucket?FermoTemp™ Electric Fermenation HeaterBEST ANSWER: It should work fine. It just wraps around the outside of the bucket and has a temperature sensor probe. I tape the probe to the outside of the bucket, then just use masking tape to tape the heater over the temperature sensor and to the bucket.Would this keep a 6 gallon batch above 90*f in a 70* f room for a hi temp yeast like Hornindal Kveik?BEST ANSWER: I have not used the yeast that you mentioned but your main concern sounds like a desire to achieve a temp. above 90 f. I ferment in a room with a similar constant 70 f temp.When I used this unit, It struggled to increase the batch in a 6 gal carboy 2-3 degrees. I used a blanket wrap along with this item and it still didn't increase it nearly where you want it to go.I only bought the wrap and not the controller, can I just wrap it and turn it on and store it in a (sometimes VERY) cold place? will it maintain a good temperature for fermentation if the surrounding temperature fluctuates?BEST ANSWER: Here is what I would do if you didn't buy the controller, fill the fermenter with water and put the wrap around it in the place you plan to ferment at. Then monitor the temp on a daily basis to see if it keeps you at the temp you want. I did this with the controller and got it to a point that I can live with.
