Wrapping a fermwrap

[BrewChem]

putting together a temp control system and will be using a fermwrap for saisons... is it safe to wrap a blanket around the fermwrap to keep the heat in..?

I don't have the operator's instruction anymore, but I thought they cautioned against that. I've always found that my fermwrap is TOO warm as it is, so I usually just have part of it taped on and most of it loose.

I do 5 gallon batches and the coolest by basement gets is 54F in the winter.

Agree with too warm. Have to back it off of the carboy some.

I have been using a carboy parka around a fermwrap for a couple years now. I do this inside of a chest freezer and it works very well for lagers and ales. If the ambient temperature is closer to fermentation temperature you can probably leave out the parka.

I use a Fermwrap with this temp controller--about $30 on Amazon. Control range from 68-108F. Just tape the temp probe to the side of the fermenter (not on the Fermwrap).
