Fermwrap and Carboy Jacket? (for warm fermentation)

Is it safe to slip a Carboy Jacket over a Fermwrap that's taped to the side of your carboy?

The Fermwrap only kicks out 40 watts of heat.

My ambient temperature is 65F, I'll be pitching at 75F, and would like to maintain fermentation temperature of 85F.

What the hizzy are you fermenting at 85F? Just a curious newb.....

I have an old school heating pad without an auto shutoff that is rated at 60w. I thought I'd be safe and wrap some very thick material around it (think quadply canvas folded over 4 times) to make it more consistent and to hold the pad on. With that on "low" I accidently overshot my and hit 75 with ambient at 55. I had to peel back the material and let it cool. This will be an interesting brew.

I'd give it a shot without the wrap first to see how you do with live yeast in there. Live yeast will give you a good 5+ degree gain in the chamber over any standing water test you do. If you find you do need a wrap, you'll be safe. Just play Mr. Safety and keep an eye on things.

this is the question.

85F??

WY3724, the Dupont strain. I usually brew saisons with WY3711 at 73F - 76F with ambient house summer temperatures but I need a new challenge. I'm also tired of waiting until summer to brew them.

3724 is a strange beast. I have a friend who turned a great saison out around 85F - 88F.

Update: I've been advised NOT to have the carboy jacket touch the FermWrap. Potential fire hazard. Looks like I'm going to build a foam board fermentation chamber instead.

Just brewed a saison and my house temp is 71, i'm too looking for a 80ish temp to ferment at! Any ideas as to how much this fermwrap will raise the temp if left on? Will it continue to heat to the 90's!? I have 5.5 gallons in a glass carboy.

I use a heating pad with a temperature controller and probe stuck into the fermenter. I just put the fermenter on the pad and let the heat rise through it. Works great.

Yeah, sounds perfect! Sadly i don't have a temperature controller that can handle being in liquid. I have that regular temperature controller that has that bulb like probe. Not sure if it can be in liquid. Are you using a Thermawell?

Nah the one I got was designed for incubating plants and the probe is designed to be planted in soil. I just stuck it in a baggie and put it in the fermenter.

Something like this. I don't think that exact model, but fairly similar.
