Northern Brewer - FermoTemp Electric Fermentation Heater

The FermoTemp Electric Fermentation Heater works perfectly on my carboy! It wraps around easily and provides consistent, gentle heat to keep my fermentation temps right where they need to be. Super reliable and great for year-round brewing—highly recommend for any homebrewer!

Just what I needed for the winter months - keeps my mash nice n toasty for the week of fermentation

Works as it should, I have it powered through an Inkbird. It does what it is supposed to do, use about 12 ferments thus far, Dam thing won't pour me a beer though.

Works great. Does exactly what it is supposed to do.

i like the way the electrical input is in the middle as opposed to the bottom. it allows for a cleaner hook up

Rigid material allows this to wrap effortless around my two gallon kombucha glass jar. Stay uniform temperature. Highly recommended.

Northern Brewer has a few pretty solid products, and this is one of them. I have at least 4 of these and they work great. It fits on both glass and plastic carboys. I use electrical tape to attach it, which is easy to remove when the beer is done and the carboy needs to be cleaned.

You need their controller to actually use this.... would've been nice to know.
