Changelog

Version: 2.1.2
Date: 31. 10. 2026
  Minor Features:
    - Added optional Heat-pipe superheater (startup setting "Enable heat-pipe superheater", off by default). A heat exchanger that takes steam (100°C or hotter) and heats it to 465°C using heat pipes. Unlocked by Nuclear power, made from a superheater and 4 heat pipes. No efficiency bonus, since heat pipes pass energy 1:1. Also usable with heat networks from other mods.

Version: 2.1.1
Date: 31. 10. 2026
  Bugfixes:
    - Factorio 2.1.22 compatibility: the superheater's 100°C minimum steam temperature now uses the new boiler minimum_input_temperature (fluid box temperature limits were removed in 2.1.22). Older 2.1 versions keep using the fluid box setting.

Version: 2.1.0
Date: 25. 10. 2026
  Info:
    - Continuation of Superheating by GotLag, maintained by FallenPaladin for Factorio 2.1.
    - All original art, design and balance by GotLag. Uses the same prototype names, so saves using the original Superheating carry over.
    - Not compatible with Superheating or Superheating (Balanced) at the same time (they add the same machines).
  Bugfixes:
    - Two-stage boiler + superheater now gives the full 60 steam/s (5.4MW per pair) instead of 40/s (3.6MW). The cause was a boiler bug in Factorio 2.0 that ignored input temperature, which Wube fixed in 2.1. "Single-stage superheaters" no longer needs to be turned on as a workaround.
    - Coal-fired superheater now accepts every fuel the vanilla boiler accepts, including fuels added by other mods (Krastorio 2 / K2 Spaced Out, AAI Industry processed fuel, etc.).
    - Superheaters and oil-fired boilers now follow the vanilla boiler's placement rules (Space Age: no longer placeable on space platforms) and heating/freezing behaviour.
    - Superheater efficiency is re-applied at the end of loading, so overhaul mods that rewrite boiler efficiency can no longer cancel the 200% bonus.
    - Technology no longer errors if an overhaul mod removes one of its prerequisites or unlocked recipes.
  Changes:
    - Updated for Factorio 2.1.
    - Superheaters accept steam at 100°C or hotter (was 165°C), so steam from mods that boil at 100°C can be superheated. Idea from Superheating (Balanced) by tntmasta.
    - Item sounds and tint are copied from the vanilla boiler item instead of hard-coded base files.
    - Added descriptions for every startup setting, including where to find them.
    - Entity descriptions now state the fuel efficiency.
    - Code cleanup: shared constants, no duplicated energy source tables.
