C4, C3 specifications

Burnham’s C3 and C4 series are notable for their innovation and efficiency in the commercial heating market. Designed with the modern user in mind, both units prioritize performance, adaptability, and ease of use, making them ideal for a range of applications from schools to industrial facilities.

The Burnham C3 is equipped with a three-pass heat exchanger, allowing for maximum efficiency and effective fuel utilization. This design ensures that the flue gas passes through the heat exchanger multiple times, extracting additional heat before venting. This results in lower emissions and increased fuel savings, making it an environmentally friendly option. The C3 is available in a variety of input capacities, catering to the diverse needs of different buildings.

On the other hand, the C4 series is built around a four-pass heat exchanger, further enhancing efficiency standards. This advanced design also extends product life and reduces maintenance requirements. The C4 is particularly well-suited for larger commercial applications, offering higher input capacities without compromising performance. This series is designed to work seamlessly with a range of control systems, enabling easy integration into existing heating setups.

Both units feature advanced burner technology, delivering a more thorough combustion process that improves overall heating efficiency. They utilize durable materials and construction techniques to ensure longevity, alleviating concerns about frequent repairs or replacements.

In addition, both C3 and C4 models boast user-friendly control interfaces, simplifying the process of monitoring and adjusting settings. Optional modulating controls allow for precise temperature regulation, further enhancing energy efficiency during varying load conditions.

A significant aspect of these boilers is their commitment to safety. They are equipped with multiple safety features, including flame safeguard systems and high-temperature limit switches, ensuring reliable operation under all conditions.

Overall, the Burnham C3 and C4 series stand at the forefront of commercial heating technology, combining high-efficiency performance with innovative features. Their adaptability, reliable construction, and focus on sustainability make them a strong choice for facilities looking to improve their heating systems while reducing environmental impact. As businesses look toward more efficient heating solutions, the C3 and C4 models represent a smart investment in long-term operational excellence.
