Spike Brewing | Flex Heater

Need to heat your Flex during the long Winter months? Want to make a Belgian ale with notes of pears, bananas, bubblegum, anise or even rose petals? No fear, we have the solution! Each Flex has its own sized heater and the wattage of each is carefully designed to match it. With a built-in thermostat, this stops the heater from getting too warm.

This 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!).

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.
