Which of the following are advantages of packaged watertube boilers?

The choice highlighting ease of installation and the convenience of having all components supplied by one manufacturer accurately represents significant advantages of packaged watertube boilers. These systems are designed and constructed as a complete unit, which means they arrive on site with all necessary components already assembled. This not only simplifies the installation process but also reduces the time and complexity typically associated with setting up a boiler system.

Having one supplier responsible for all elements can also enhance accountability and streamline communication, as all components are designed to work together seamlessly within the system. This can lead to improved reliability and potentially better performance since the parts are specifically engineered to be compatible.

Further, it minimizes the risk associated with sourcing individual components from different suppliers, which can vary in quality and performance, potentially affecting the system's efficiency and reliability. This integrated approach is one of the main reasons packaged watertube boilers are favored for various applications, especially in settings where space and installation time are critical factors.
