What is the primary function of a boiler in a heating system?

The primary function of a boiler in a heating system is to produce steam or hot water for heating. This process is essential for various applications, including space heating, industrial processes, and domestic hot water supply. The boiler works by burning fuel or utilizing electricity to heat water in a closed system, generating either steam or hot water that can then be distributed through pipes to radiators, baseboards, or other heating devices within a building.

This function is central to maintaining comfortable and safe indoor temperatures, especially during colder months. By efficiently converting energy into heat, the boiler plays a crucial role in the overall heating infrastructure. While generating electricity, regulating air flow, or filtering water may be related to energy systems or overall plant operation, they do not define the primary role of a boiler in heating applications.
