In recent years, condensing boilers have been favored by more and more users, and the frequency of use is also increasing year by year. It can be said that the advantages of condensing boilers are recognized by more and more users. However, for users who are new to boilers, condensing boilers are still a relatively novel type of boiler. Zhengzhou Fangkuai Boiler Factory will explain to you what type of boilers condensing boilers are, and what advantages they have.
The condensing boiler is based on an ordinary boiler with a new condensing heat exchange device. Through this device, the thermal efficiency of the boiler can be increased by more than 10%, reaching about 80%. The thermal efficiency of the condensing boiler of Zhengzhou Fangkuai Boiler Factory is even higher. Up to 98%.
In addition, the heat exchanger used by Zhengzhou Fangkuai Boiler Factory for the condensing boiler has relatively high material requirements and has a strong anti-corrosion ability. Since the discharged flue gas will contain a large amount of acid gas such as carbon dioxide, when the flue gas is converted into condensed water, it will have varying degrees of acidity. The long-term contact of traditional converters with condensed water will cause its surface to be corroded and scratched. The changeable condensing boiler converter is made of very stable materials, reducing component corrosion damage and Zengcheng use time.
The energy-saving benefit of the condensing boiler is also very high. The temperature of the low-temperature fluid inside the condensing boiler can reach a very low level, which is good for taking away and reducing the flue gas. The water vapor condensate also increases the display heat and latent heat that can be recovered There are also more and more, so the efficiency of the use of heat energy of the condensing boiler is also greater.






We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance. Join us at Booth No. B1-08 from November 5–7, 2025 at the Jakarta Convention Center.
The event brings together EXPO BOILER, EXPO BIOMASS, EXPO PUMPS & VALVES, and EXPO CRANE — creating a comprehensive platform for technology exchange and business collaboration across the industrial heating and energy sectors in Southeast Asia.
At the exhibition, we will present our integrated solutions including biomass boilers, industrial steam systems, and full power plant EPC services. Our products emphasize:
