Adds a version of the assembling machine, chemical plant, and furnace that runs on heat! Also adds two other ways of generating low-level heat! Part 1 of the my bigger GasHeatStuff collection.
The Steam Heater can be unlocked with only Red Science but the crafting-recipe requires Iron Sticks, which can only be unlocked with Green Science.
Would be great if the Steam Heater Tech also unlocks the Iron Stick recipe.
