And Here is Flex-Watt Heat Tape, as used in herpological applications. They are all exactly the same stuff, the homebrew products are just cut to fit carboys and pre-assembled. It's just a big resistive element, really.

You have to base the choice on what temp you want to ferment at, not necessarily an analytical choice in the optimum range. Different points in that range will create certain flavor profiles, all temps will make beer. The profile you want comes from experience. You need to remember that the fermentation itself generates heat. I am sure that your temp ...

I doubt you'll have an issue. Fermwraps don't get hot enough to auto-ignite anything (It can't even bring water to a boil without melting the plastic), so I doubt anything will catch fire due to the heat of the FermWrap. If there's an electrical fault somewhere, well that's beyond the scope of this question and forum. I'm going to guess in most cases, ...

You absolutely can use a BrewPi without any chamber, be be aware it will be much more difficult to maintain proper temps if your environment has wide swings in temperature throughout the day. Also, it will be more expensive to maintain temperature. Isolating your fermenter from the outside environment allows the Fermwrap to work much less as the chamber ...

Yes, wrapping the carboy in a towel will act as insulation and retain some of the heat. Fermwrap's do require some amount of trial and error to find their sweet spots. Keep in mind that while the Fermwrap is powered on, it is actively generating heat. Immediately cut the power, and while it is no longer generating heat, the wrap itself is still warm, ...

I've wrapped towels, insulation, and lots of other things around a FermWrap without issue. I like to use mine for sour-mashing, so I'll place a FermWrap around a boil kettle, then use a heating blanket to help give it insulation and an extra heat boost. There have been no adverse effects, and nothing has caught fire yet, so I wouldn't be too concerned ...

I understand that the Johnson A419 Temperature Controller can only do hot or cold at one time. Which mode does it default to when you buy it? Cold Not sure whether or not the default mode was cold Check to see if there is a snow-flake icon to the right of the temperature, indicating that it is set to cold. I can't recollect off the top of my head what ...
