Which type of boiler is noted for its low initial cost?

The fire tube boiler is recognized for its low initial cost primarily due to its simpler design and construction compared to other types of boilers. In a fire tube boiler, the combustion gases flow through tubes that are surrounded by water. This configuration allows for easier manufacturing and lower material costs, contributing to an overall reduced price for installation.

Moreover, fire tube boilers typically require less complicated technology and fewer sophisticated controls, which can further lessen the initial investment for buyers. This makes them a popular choice for smaller applications and industries where cost is a critical factor.

While other boiler types have their unique advantages, such as efficiency or specific applications in high-pressure environments, fire tube boilers stand out in terms of affordability when it comes to initial procurement and installation costs.
