Direct answer
The checked current building index does not list a Boiler. Treat “Sandustry boiler” as a search for the Steam and thermal chain, then verify the current roles of Steam Dryer, Condenser, Snowmaker, Smelter, Thermal Buffer, Burner Belt, Pyro Dispenser, and Steam Turbine in the game UI.
Field note
Start with the naming correction
Do not design around a generic Boiler assumed from another factory game. Search the current research and building interfaces for the actual Sandustry thermal entities.
Use “boiler” only as the user's query language while the page title and instructions explain the current names.
Field note
Trace Water into Steam
Water participates in the Steam chain, so isolate the source, thermal stage, Steam path, and destination. Leave capacity on both sides of the phase change and make temperature state observable.
The current index includes multiple thermal buildings, but this evidence does not support inventing one universal sequence for all of them.
Field note
Diagnose a thermal chain
Confirm material identity and phase at each boundary. Then check whether the active building is a dryer, condenser, buffer, dispenser, smelter, or turbine and whether its current UI shows the expected input.
When a guide claims a Boiler recipe, require a current official page or reproducible in-game capture before applying it.
