I made a reactor setup earlier and mirrored a side. After a while I noticed that the west side was performing worse than the east. So, did a quick test.

Images here.

The setup. 43 heat pipes in a line, connected to one side of a reactor.

Travelling east.

The fourth pipe in the line reads 983.33°C. All other pipes read 1000°C.

Travelling west.

The third pipe reads 983.33°C. All further pipes read 983.33°C.

I didn't bother to screenshot the specifics of north/south. Difficult to capture entirely in screenshot form.

Travelling north.

This is the strangest one of the lot. All pipes are 1000°C. *Except* for these: 2, 9, 16, 20, 21, 28, 33, 34, 36, 38, 40. All of which are 983.33°C.

Travelling south.

At first glance, the direction that seems to work as intended. The pipes connected to heat sources are 1000°C and gradually decrease to 466.67°C at the end of the line. Except for one blip where it goes 700.00°C, 666.67°C, 683.33°C, 666.67°C. And another where it goes 616.67°C, 633.33°C, 616.67°C. And then sticks at 600.00°C for 6 pipes.

I think that's normal behaviour. It's just where a bit of "heat pressure" was missing in the "heat pipe" while flowing. You get that in fluid lines too... some segments show slightly lower pressure at times. Doesn't seem to affect endpoint performance or throughput. I got a sneaky suspicion "heat" is defined as a fluid using the same fluid mechanics system.

Thanks for the report. This should be fixed in 0.15.11. (the next version of 0.15).
