you could try swapping the out tc port and the thermowell. Getting flow past the tip my help. The thermowell needs to be long enough to reach into the flow.
Also, have you checked the calibration of the temp controller probe? It may be off. Then it would be helpful to also check the...
I have spent a lot of money at brew hardware and have been happy to do so. They have products that no one else has, and they work well. I am glad they are still around.
Not sure this applies. I made 10 gallons of 1.040 wort then canned it for starters. Is fermentation required, if so this can be not counted.
1181.75 + 10 = 1191.75
The brewbuilt uses standard size triclamps which is nice. The brewbuilt conicals are very nice. The mini uni is nice in that it can cool a wider range of volumes, like 5 and 10 gallons. Often a half size ferment does not rise to the jacketed area to get cooled.
It also helps to recirculate for a couple of minutes before turning on the element. It gets the flour in the mash and not on the element. I figured this out the hard way.
Control fermentation Temps, even a glass carboy in a fridge, will be huge. Then o2 free transfers. After that it is controlling mash temps. That can be fine with just a cooler like you have now. Or, I cheap 120 volt rims system.
