Morphology

auxiliary + boiler

The meaning 'secondary/backup boiler' is directly and transparently derived from combining 'auxiliary' (extra or backup) with 'boiler' (a steam-producing vessel). This straightforward noun-modifier composition follows common cross-linguistic patterns and is predictable for a B1 learner who knows both constituents.

Etymology

Auxiliary boiler comes from ship language: auxiliary means 'extra' and boiler is the tank that makes 'steam' or 'hot water'. So it is the extra boiler used when the main boilers are not running, to give 'steam' and 'hot water' while the ship is in port.
