What is the function of a Hot Water Supply Boiler?

1. To store hot water

2. To provide hot water for external use

3. To heat water for internal circulation

4. To generate steam

The correct answer is: To provide hot water for external use

The function of a Hot Water Supply Boiler is to provide hot water for external use. These boilers are specifically designed to deliver hot water to heating systems, domestic hot water applications, and for processing needs in various industries. By doing so, they serve multiple purposes, including heating spaces, supplying water for washing and cleaning, and supporting industrial processes that require heated water. In contrast, other functions listed, like storing hot water or generating steam, refer to different boiler types or systems. While it is true that some hot water systems may involve storage, the primary role of a Hot Water Supply Boiler is to ensure that hot water is readily available for immediate use. Additionally, boilers that heat water for internal circulation primarily focus on creating a closed loop system for heating rather than providing hot water for external applications. Understanding these distinctions clarifies the specific operational role of the Hot Water Supply Boiler.
