A boiler is primarily designed to do what?

A boiler is primarily designed to supply hot liquid or vapor for heating. This function is central to a boiler's purpose, as it operates by heating water to create steam or hot water, which is then circulated throughout a building for space heating or used in various industrial processes.

The design of a boiler focuses on maximizing thermal efficiency while providing consistent and controllable heat output, making it an essential component in residential, commercial, and industrial heating systems. In contrast, generating electricity, storing fuel, and providing cooking surfaces are not the primary functions of a boiler, as these operations fall under different equipment and systems tailored specifically for those purposes.
