BIAB is a good option. Very simple to learn. The other way is an all in one all grain electric brew system. There are a number of them just make sure you get a 220v version.
I had a similar experience with mine & got a small fan on Amazon. It works great to even out temps. It is small enough that I can still get two corny kegs in.
I typically get 10-11 kegs before I have refill. I check for leaks about once a week I replace post o-rings every time I refill a keg & check the regulator for any leaks. If you have relieving regulator make sure it’s not relieving all the time.
That’s a discussion on fermentation. This was about strike temp , mash in, & maintaining temp for creating a wort. This equipment is made for repeatability.
For the Brewzilla the HED (heat exchanger), & the Bluetooth thermometer. This combination provides better control of temps for your mash.
I have been very happy since I added these two items. They are inexpensive.
Stick with Brewzilla. I have a number of people trying to figure out how it works. If you’ve got a Brewzilla. Work through the learning curve. Both units have learning curves.
What do you need to know?
Brewing today. I am 30 min into it. I have been on a mash temp of 153. The range of my temps have been within +\-1 f. With 20 min at 153.
Just checked again and I’m 153.4 & holding.
Something I forgot to mention. Because we are trying to get the best repeatability on our beers I looked at the sensor on the base of these units. Repeatability is the key to temp control. The sensor on the base of the unit can be keyed into what we do in homebrew. Look at the low calibration...
I also am no newbie. I have the 35l version & found it to have a large learning curve. I brew all the time and each batch presents its ow challenges. I have had good success with the HED & Bluetooth thermometer. I have to note that I also use a precision analogue thermometer to read to the...
