Frequently Asked Questions

Q: What is the difference between a hot water boiler and a steam boiler?

Hot water boilers heat water to a temperature below boiling point for space heating or process water, whereas steam boilers heat water until it vaporizes into steam for high-energy industrial processes.

Q: How do you achieve a thermal efficiency of up to 98.1%?

We utilize a combination of large heating areas, corrugated liners, threaded flue pipes, and advanced condensers to recover maximum heat from exhaust gases.

Q: Are these boilers compliant with environmental NOx regulations?

Yes, by integrating imported high-precision burners, our boilers ensure that NOx emissions remain ≤30mg/Nm³, meeting strict global environmental standards.

Q: What safety features are included in the automatic control system?

The system includes high-sensitivity gas leakage valves, over-temperature warnings, and over-pressure safety trips to prevent accidents.

Q: Can the boiler switch between gas and oil fuel?

Our dual-fuel designs allow for efficient operation using either natural gas or oil, providing flexibility based on fuel availability and cost.

Q: What is the typical maintenance cycle for industrial hot water boilers?

While our automated systems reduce manual work, we recommend quarterly inspections of the burners and annual descaling of the heat exchange surfaces to maintain peak efficiency.
