Hydronic boilers utilize a closed-loop system to heat and circulate water or a mix of water and glycol. These boilers are particularly suitable for large commercial buildings with multiple zones or radiant heating systems. Hydronic boilers provide consistent and even heat distribution, ensuring optimal comfort and energy efficiency.
Fire-Tube Boilers
Working Principle
Fire-tube boilers operate by heat transfer through the walls of a cylindrical vessel filled with water. Burners located at the bottom of the boiler produce hot gases that travel through tubes running through the water-filled vessel. The heat from the gases is absorbed by the water, generating steam or hot water.
Features and Advantages
Fire-tube boilers are known for their simplicity, compact design, and ease of maintenance. They are cost-effective and have a relatively low upfront cost compared to other boiler types. Fire-tube boilers offer quick heat-up and response times, making them suitable for applications with fluctuating load requirements.

They are suitable for heating large buildings, such as schools, hospitals, and office complexes. Due to their versatility and robustness, fire-tube boilers find applications in various industries, including manufacturing, processing, and hospitality.
Water-Tube Boilers
Working Principle
Water-tube boilers operate based on the circulation of water through a network of tubes heated by external gas or oil burners. As the water circulates through the tubes, it absorbs heat, generating steam or hot water. The steam or hot water is then distributed to various applications within the building or industrial facility.
Features and Advantages
Water-tube boilers offer several advantages, including higher pressure and temperature capabilities, improved efficiency, and increased resistance to thermal stress. Their flexibility allows for better control over the heat output, making them suitable for industries with specific requirements.
