I'd also like to ad my thanks to "Yambor44" for taking the time to record and post such extensive video coverage of the Braumeister in action. The more I see, the more I think that the 50l is the correct choice for me.
Now, apart from the fact that it's $1K more than the 20l, I have to decided how I'm actually going to use the thing. My basement has 7' ceilings, but I don't think that's enough, unless the unit is operated down near the floor, and I don't want to put a 240V outlet in the kitchen.
The real issue is having the clearance to remove that malt pipe. The easiest solution to this, whether from the standpoint of wiring the 240V or headroom, is to go to the garage.....but IL ain't FL in the Winter.
