Spike Brewing | 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).

This 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!).

Technical Features 

• Built in 95F thermostat to prevent the heater from overheating your wort 
• 80 watts of power 
• Durable silicone construction 
• 5' long cord

Note: Spikes heaters were designed to keep the wort within normal fermentation temperatures. Yeast strains (like Kveik) that require higher temperatures (90F+) may require an additional heat source.

Pro Tip: If you’re looking to ferment with Kveik yeast, we recommend taping the heater to the cone as it'll help aid in heat transfer and provide for high fermentation temps.
