What is the primary purpose of a boiler?

The primary purpose of a boiler is to generate steam or hot water for heating. In many industrial and residential applications, boilers play a crucial role in providing the necessary heat, whether for space heating, industrial processes, or generating energy. This heat is produced by burning fuel or using electrical energy to heat water or generate steam, which can then be distributed through piping systems for various uses.

While storing fuel for combustion is important for the operation of a boiler, it is not the boiler's primary function. Similarly, cooling the surrounding environment is outside the operational scope of a boiler, which is designed to produce heat rather than dissipate it. Additionally, filtering impurities from water is an essential part of water treatment processes, but it does not pertain to the main function of the boiler itself. Thus, the focus remains on the boiler's ability to generate steam or hot water as the fundamental purpose.
