What is the primary purpose of a boiler?

The primary purpose of a boiler is to produce steam or hot water. Boilers are essential in various applications, such as heating systems, industrial processes, and power generation. They operate by heating water to a specific temperature, which then converts to steam or remains as hot water, depending on the system's design and requirements.

This process of generating steam or hot water is crucial because it provides the necessary thermal energy required for different applications, such as heating spaces in buildings, maintaining processes in factories, or as a heat source in electrical generation. The ability to produce steam efficiently allows boilers to play a vital role in many industries, making them indispensable for comfort, industry, and energy production.

The other options revolve around functions that are not the primary objectives of a boiler. While boilers can be part of systems that contribute to electricity generation or heating for cooking, their fundamental operation and design are centered on producing steam and hot water, highlighting the importance of this function.
