• It also doesn't seem to care if the temperature is 15, already at 165 or even if it's at 500. Just takes H2O input and outputs H2O at 165 degrees.
• If you install the steam cooling mod along side this and loop the steam through it to keep the temperature up, you still fall short of 165 before it gets where it's going. Should probably make the steam output from the reheater be just a little higher than required. Doing the same for the vanilla heat exchangers too wouldn't be a terrible idea. Assuming of course that this and steam cooling are installed together.

I cannot make old good boilers, where you are need 14 boilers to get 165° "water-steam" fluid.

The steam cooling mod can cooling only pipes and storage tanks, so you can use the direct connection and there you have 165° steam.

I've asked about the right reheaters: https://forums.factorio.com/viewtopic.php?f=28&t=86787

Maybe try using the code for the old boiler, not just adding the mode prototype to yours. I imagine that it probably takes issue with there being multiple outputs(the in/out on the water input side).

I can change it right now, but you get not necessary output. And you must change your factory.

You can put the steam into the A and got the hotter steam from B, or put into the B and get hotter steam from the A, but 1. You cannot get steam from output C or 2. you cannot delete output C.

Somehow fixed in the 0.0.2.
