Vertical firetube boilers are advantageous when which of the following is limited?

Vertical firetube boilers are particularly beneficial in situations where floor space is limited. This design allows the boiler to occupy a smaller footprint than traditional horizontal models, making it ideal for installations in buildings with space constraints. Vertical boilers can often be placed in tight areas and utilize height rather than width, allowing for efficient use of available vertical space.

In applications with limited floor space, vertical firetube boilers provide the same capacity as larger horizontal units while minimizing their impact on the overall layout of the facility. This is especially advantageous in commercial or industrial settings where minimizing the required ground area for equipment is a priority or where building codes may restrict the use of larger equipment.

Other factors, such as ceiling height, fuel supply, and water quality, do play important roles in the selection and effectiveness of different boiler types, but these are not the primary considerations that make vertical firetube boilers stand out. In situations with restricted floor space, their vertical design allows for optimal placement and efficiency.
