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 the 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!).
