That is exactly what you saw. The mash water is pumped up through the "grain cylinder" and heated with perimeter heaters.
I have been eyeballing this for a while. I like the compact design. What I don't like is the fact that there is no sparge function. If you want to sparge you have to heat your sparge volume on a second heat source and rinse by hand by dumping water into the gran cylinder when it is in the drain position.
I am curious what the efficiency would be if you just mashed with your full volume(mash in + sparge) for a 5 gallon batch in the 50L system.
