1) Setup: LHE, HP Turbine (Bottom Right), Turbine (Bottom Left).
a) The Front-most face for the LHE is the output. The output splits into both turbines because its not going to produce 100% superheated steam (when you begin sending it hot coolant, it will almost certainly generate a bit of regular steam first)
b) The HP turbine outputs steam into the regular Turbine
c) The regular turbine outputs distilled water into the side of the LHE.
d) The BC tanks full of distilled water aren't actually being used at all. I ended up using cells.
2) I've put 8 buckets of distilled water into the LHE. While running, that level fluctuates. I saw it get down to 7988 at one point, while running at around 40% efficiency.
3) After I shut off the hot coolant, and let the remaining steam get processed....we get back to exactly 8000mB of distilled water.
Closed loop.
