I want to thank you again for your continuous work on this project.
I'm not sure if this is a bug, or something peculiar to my installation (mods, settings, etc.).
Heat Exchanger 2 works fine. But I cannot get Heat Exchangers 3 and 4 to produce any useable output. Putting H.E.2 back in the setup restores proper function, but only after completely flushing all the H.E.3 produced steam. (i.e. deconstruct the H.E.3 AND the attached turbines first.)
To add more detailed information to the inexplicable weirdness: I can fill a storage tank with steam using H.E. 3, but if I connect a Turbine (of any level) to the tank, or even a fluid pump, the turbine status shows "No input fluid." Even a regular Steam Engine attached reads the status as"No input fluid" and yet I can pump the steam around using pipes and fluid pumps. It's as if the steam is both there and not there at the same time.
Playing around a bit, I discovered some more clues/strangeness using this setup: I put down a properly heated and fully functioning H.E. 2 and attached a storage tank to it's output, and then connected a Turbine 3 to the storage tank and the turbine starts generating. If I replace the H.E.2 with H.E. 3, the turbine slowly stops even though the storage tank keeps filling. If I re-replace the H.E.3 with the original H.E.2 (reconnecting it to the storage tank) the turbine won't start working until I flush the steam from the entire system.
It's almost as if steam outputted from an H.E.2 is partly the same and yet also partly different from steam from an H.E.3. You can mix the two, but it is as if H.E.3 steam somehow contaminates H.E.2 steam, and breaks the system.
Very puzzling to me, but maybe all this (extra-wordy) info helps you help me?
