Steam Engine Help

[LazyKyle]

Working on a custom setup. The steam engines on the left are all at 100C, but the ones on the right *all* fluctuate a very small amount and max at 95.12C and I can't figure out why. They're both 14:10:1 ratio. Any ideas?

Try re-doing the boilers and piping, making sure you lay them down in the same sequence as the water flow. Owing to how Factorio handles fluid flow, you can get weird behaviour if the pipes were laid backwards to the fluid flow.
