If there is a 3,000-square-meter factory building, starting the heating equipment in cold weather is a very important link. So, how big a hot water boiler is needed for the heating area of a 3,000-square-meter plant? How to accurately choose the boiler model and tonnage? Let Zhengzhou Fangkuai boiler manufacturer tell you the answer.
First of all, it is necessary to judge how big a boiler is needed, and to understand the boiler model, the thermal efficiency of different models of hot water boilers will be different, resulting in different heating areas. The thermal efficiency of the hot water boiler launched by Zhengzhou Fangkuai Boiler Factory is above 98%, which is a very high figure in the entire boiler market. This type of boiler only needs half a ton to heat a 3,000-square-meter plant.
The 0.7Mw of the boiler refers to the rated heat supply of the boiler, which can output 0.7 MW per hour, which is equivalent to a traditional 1-ton hot water boiler. During a day or during a heating period, there will be heating peaks and valleys. The average load means that the total heat supply does not exceed the boiler's total heat supply. At peak times, the heating load will exceed the boiler's rated heat supply. In the low valley, the boiler will have a large margin. We add the total load of the peak and the valley and divide it by the time to get the average load. At peak times, the boiler will be overloaded, users will have insufficient heat supply, and there will be heat waste in the boiler during low valleys. Therefore, the selection and configuration of the boiler must be reasonable.
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:
