Looking for reliable China suppliers? Our boiler factory offers high-efficiency Gas and Oil Hot Water Boilers with rated thermal power 0.7-140 MW, working pressure 0.7-1.25MP, and NOx emission ≤ 30mg. Compatible with Natural gas, Lpg, biogas, and coke oven gas.
About this product
Product information from the supplier.
Our advanced Gas and Oil Hot Water Boilers are engineered for maximum thermal efficiency, utilizing a precision combustion process where natural gas or oil fuels heat the water within the boiler pot. By continuously optimizing the energy release from the furnace, these systems generate a stable and high-temperature hot water supply tailored for demanding industrial and commercial applications.
Designed with a focus on sustainability and safety, these boilers integrate cutting-edge technology to reduce NOx emissions and minimize heat loss. From the corrugated liner to the fully automated control systems, every component is optimized to ensure reliable operation, lower operational costs, and compliance with strict environmental standards.

Frequently Asked Questions
A hot water boiler heats water to a specific temperature without boiling it, primarily used for space heating and process heating, whereas a steam boiler converts water into steam for high-energy industrial processes.
The corrugated liner increases the heat transfer surface area and creates turbulence in the flue gas, which slows down the gas flow and maximizes heat absorption into the water.
Yes, our models are designed for versatility and can be configured for either natural gas or oil fuel depending on your facility's requirements.
We utilize high-sensitivity gas valve groups and integrated electronic sensors that trigger an automatic shutdown if a leak or abnormal pressure is detected.
While our automated systems simplify maintenance, we recommend a professional inspection every 6-12 months to ensure optimal thermal efficiency and safety compliance.
Yes, the full-automatic control system allows users to set and maintain precise output water temperatures ranging from 95℃ up to 130℃ depending on the model.
