Hot water boilers and steam boilers are relatively common boiler equipment on the market at present, and the output media of the two are different, and the application places are also different. Hot water boilers are more suitable for air conditioners, heaters, low temperature ovens, drying equipment, hot water tanks for textile printing and dyeing, and various low temperature heating, air conditioning coils and heat exchange equipment. Steam boilers are suitable for industrial sites such as chemicals, building materials, and food processing. What is the difference between a hot water boiler and a steam boiler? How to choose suitable boiler equipment as a user? Zhengzhou Fangkuai Boiler Factory will answer for you.
1. Hot water boilers generally have a low heat medium temperature and a large temperature difference with the flue gas. The boiler exhaust gas temperature is relatively low, so the efficiency of the boiler will be higher.
2. The hot water boiler adopts a closed hot water system, the amount of make-up water is small, the blowdown rate is much smaller than that of the steam boiler, and the water waste is also small. In addition, the boiler water quality requirements are low, and the water treatment costs are low.
3. The heat capacity of the water in the hot water boiler is large, the hot water capacity in the system is large, and the heat storage capacity is strong. When the thermal or hydraulic operating conditions fail for a short time, it will not cause significant fluctuations in the heating conditions.
4. The hot water heating system can be pumped for long-distance transportation, with small heat loss and large heating radius, which can meet the requirements of urban central heating planning.
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:
