Package boilers are preferred for commercial applications primarily because they are compact and prefabricated. This design allows for easier transportation and installation in a variety of settings, making them a practical choice for facilities with space constraints or where rapid deployment is needed. The prefabricated nature of these boilers means that they come as a complete unit, which can often be installed more quickly than traditional boilers that may require extensive on-site assembly and integration.

Additionally, the compact size allows for flexibility in locations where larger boilers would not fit, such as in smaller buildings or facilities with limited floor space. The efficiency of having all components—including the burner, controls, and steam system—integrated into one package contributes to their popularity in commercial environments, where efficiency and practicality are key.
