Before i got my BZ Gen 3 i did biab in my klarstein 30L fullhorn which i still have, the reason i got the bz was to eliminate the bag which i hated with a passion, when i first looked at the bz i thought it's a fancy fullhorn with added bits the most important of those bits to me were the basket and pump, i never had any intention of using it for any other reason just biab which it does very well
I did the same. I used to BIAB with a peco boiler and wasn’t a fan of the bag either, so now brew in a malt pipe
Draining the bag was a pain and I needed another FV to let it drain into, it made a mess. Batch sparging was more effort than it is now.
I got a BZ 3.1 as B Stock from BKT for £280 a few years ago.
I don’t use any of the automatic functions, I just manually set the temps I want and change them when I need. I use a WiFi plug to switch it on to pre heat mash water using my phone whenever I need to do that as it’s easier.
I even purchased the upgraded control board and display (3.1.1?) but I’ve not fitted it as the older one does what I need, so it’s kept as spare.
I pretty much do the same process as my last set up, but being able to lift the malt pipe out and rest on top to sparge is way easier than sparging with the peco, and being able to set temps on the heater without messing around with hot and cold water and blankets makes for a much smoother brewday.
Cleanup is about the same amount of effort.
Advantage of the peco over the BZ is that I could do higher gravity brews in the peco, where my efficiency drops with anything more than 5kg of malt in the BZ, and absolutely tanks with 6kg or more.
I did look at a digital boiler, but by the time you add pipes, a pump and a malt tube or basket it would have been more than £280, so I’m well chuffed.
If I ever do another upgrade it will be for more volume, rather than disliking the BZ. Although that’s unlikely as it would mean purchasing a new fermentor and bigger fridge
