I’ve finally setup a fridge fermentation chamber and was wondering the thoughts on how close/far the heat pad should be from the fermenter.

You can see my position currently in the image.

Pitched an US IPA around 6pm today at 23c. I’ve set the target temp for 21c on thermostat. Thermo gauge is in the wort using a homemade thermowell (
). Temp dropped to 20c at 8pm and heat pad kicked on, now at 20.5c at 9.45pm. I guess this seems to be ok but keen to hear any other thoughts/experiences for best position to get target temps faster.

Cheers!

Great idea on the thermowell CB, that should work a treat. As far as your heat mat goes it looks like it is doing the job. The only other thing you could do is place it on the lower shelf. Looks like you have the temp exactly where you want it.

I reckon hanging on the inside wall is the way to go. I’d be cautious applying heat directly to the bottom of the fermenter.

Small temp fluctuations aren’t a massive deal, and it takes quite a while for 20L of beer/wort to change temperature. You don’t want things to change too quickly, as it can stress the yeast out.

like most things in brewing, consistency is the name of the game.
