Spike Brewing has the solution for cooler-than-ideal fermentation temperatures! This conical heating unit is designed to work with their Flex Fermenters. This heater has a built-in 90F thermostat that allows for gentle warming for optimal fermentation conditions. It attaches to the insulated Flex jacket via velcro and sits at the bottom of the conical cone, where it can heat the coldest liquid and give you the most consistent temperature throughout the wort.


  • Built in 90F thermostat to prevent the heater from overheating your wort
  • 80 watts of power
  • Durable silicone construction
  • 5 foot long cord
