A couple of comments: -There were only two flowmeters on the water from the pumps. The two pumps without were not running. (There is a number of valves on the pipes from the pumps to the Ecats, but it is hard to know exactly the position on all of them from the videos.)
-There was a valve on the connection to the 5l container for non-vaporized water, and it was closed. -I would move the condensers to the bottom of the figure, at the same height as the reservoir, as it would make the problem of how the water got back up into the latter more visible. -I got the impression that the reservoir 2 was connected to number 1 by a pipe all the time. -You could add the pressure meters on the outlet of the pumps, and we also know the pressure: 3.8 bar. /A.
