  • Flex Heater


Unfortunately some of us will have to heat our FLEX during the long winter months. No fear, we have the solution! The FLEX heater was carefully engineered to match the heating needs to maintain set temperatures even in the coldest winter garage. We also use a built in thermostat which stops the heater from getting too warm. This means you get a gentle warming action when your beer drops below your desired temp (opposed to rapid heating which can overshoot or 'cook' your wort).

Our heater attaches to our insulated FLEX jacket via Velcro. It is positioned near the bottom cone section of the fermenter where the coldest liquid is. This will give the most even temperature throughout your fermenter (happy yeast!).

-Built in 95F thermostat to prevent the heater from overheating your wort
-80 watts of power
-Durable silicone construction
-5' long cord
Note: Our heaters were designed to keep the wort within normal fermentation temperatures. Yeast strains (like Kveik) that require higher temperatures (80F+) may require an additional heat source. 
Pro Tip: If you are looking to ferment with Kveik yeasts we recommend taping the heater to the cone as it'll help aid in heat transfer and provide for high fermentation temps.

First one didn’t work

First one I bought didn’t work. I didn’t realize until I already had a batch in my 32 degree garage that was oddly cold. Customer service was quick to send me a new one, although they didn’t seem surprised mine didn’t work, so they may be having quality control issues with this product. They sent the new one which works fine
