[0.15.10] Some Heat Exchangers do not work.

[brevven]

This seems different than the heatpipe directional issue, but I guess it could be a strange expression of that. I rebuilt the pipes/exchangers. Some of the heat exchangers simply do not work at all. They have heat, they have water, no steam is created.

I've attached the log and the save in question.

I'm not sure if this is clear enough, but heat exchangers can only use the temperature above 500 degrees, as they are heating water to 500 degrees (because of thermodynamics).

Btw, the setup you have is the exact opposite of what I wanted to have, so I'm happy to see, that the heatpipe is way too long to support this kind of setup, You will have to rebuild it so it uses the space around the reactors to minimise the max length of heat pipes.
Btw, with the tweak in 0.15.11

Yeah, the 500 degrees thing is clear, thanks!

The 0.15.11 update definitely completely broke my layout so no worries on this bug, time to figure out a new one.
