Conical Heater

45 reviews

Need to heat your conical 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 conical has its own sized heater and the wattage of each is carefully designed to match it. We also use a built-in thermostat, which stops the heater from getting too warm.

The conical heater attaches to our insulated conical jacket via Velcro. It rests on the bottom cone section of the conical where the coldest liquid is. This will give the most even temperature throughout your fermenter.

The built-in thermostat also stops the heater from getting too warm. This means you get a gentle warming action when your beer drops below your desired temperature, as opposed to rapid heating which can overshoot or “cook” your beer.

  • Different wattages for each fermenter (ranging from 80w to 400w) 
  • Built in 95F thermostat to prevent the heater from overheating your wort 
  • 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 (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.

Replacement for a failed heater

Spike gets 5 stars for customer service. They replaced the heater with no questions asked and got it to me quickly. I only rated 4 stars because this item seems prone to failure and IMO has a design flaw. Hopefully they do a redesign soon and the power wire connection gets toughened up a bit. Thanks Spike!

New Heat Blanket

The new upgrade works great. I am a bit disappointed that the original heat blanket failed during active fermentation. The pale ale project was dry hopped at 46F but it turned out fine.

Quality and accurate

This is my first time using a heat source for fermentation that was built for it instead of home-built. Much more accurate than the hair dryer in a chest freezer I used to use. Combined with my TC controller my ESB has been sitting right at 68*. Love spike products and will definitly be spending more money with them!

Easy fix

My heater went out on my conical. Contacted Spike and they sent me another one. Works just as good or better than the original. Awesome customer service!!! Friendly and willing to help!
