A worker who operates or maintains heating systems or furnaces, especially on ships or in large buildings.
From 'heater' + '-man' (Old English 'man,' a male person or worker). Common occupational suffix '-man' was used for skilled tradespeople managing specific systems.
Before central heating became standard, 'heaterman' was a crucial job on ships and in factories—these workers had to monitor steam pressure, fuel consumption, and prevent dangerous overheating. It's a disappearing word because the job itself changed with modern automated systems.
Generic '-man' compounds historically defaulted to male reference for occupational roles. 'Heaterman' assumes the operator is male, reinforcing male-dominated trades.
Use 'heater operator' or 'heating technician' to be occupationally neutral.

Women have worked in heating trades and HVAC; occupational language should not erase them.
