Hot water boilers are mostly used for heating and heating in winter. If a failure occurs during the heating process, the user's hot water will be insufficient and the ambient temperature will be too low, which will affect normal life. Zhengzhou Fangkuai Boiler Factory summarized some common failure causes and solutions of hot water boilers to help everyone run the boiler better.
At present, most of the hot water boilers on the market adopt the structure of membrane water wall. What are the advantages of this design?
1. Since the membrane water wall of the hot water boiler has good sealing performance and better heat preservation effect, it improves the thermal efficiency of boiler operation, thereby providing more heat for production and life per unit time.
2. Because it surrounds the furnace and has good airtightness, part of the furnace wall can be saved with refractory materials, which simplifies the furnace wall structure to a certain extent and reduces the total weight of the boiler.
Many users have reported that the hot water boiler has a low water level during the operation. Zhengzhou Fangkuai Boiler Factory analyzed that it may be due to the water level sensor, the main controller, etc., or the heating system has water shortage. The specific situation needs to be finalized through detailed investigation and then resolved.
If it is a water shortage, replenish water in time after confirmation. If it is said that the water level sensor, controller, etc. have poor contact, then they should be replaced after confirmation. Of course, there will be other reasons. These should be based on the specific situation and take reasonable measures.


Recently, Zhengzhou Fangkuai Boiler Sales Co., Ltd. traveled to Dhaka, the capital of Bangladesh, to attend the Bangladesh International Textile, Knitwear & Garment Industry Exhibition (BTKG 2026). It showcased industrial thermal equipment and system solutions adapted to the whole process of textile printing and dyeing, actively expanding the South Asian market.
Bangladesh is an important global producer and exporter of textiles and garments. As a pillar local industry, the textile sector has long-term and strong demand for high-efficiency, stable and energy-saving industrial boilers and thermal equipment, with broad market potential. This exhibition participation is an important measure for Zhengzhou Fangkuai Boiler Sales Co., Ltd. to advance its internationalization strategy and further explore overseas markets.

Relying on its technological accumulation and manufacturing advantages in the field of thermal energy equipment, the company provides targeted thermal energy solutions for local textile, printing and dyeing, garment manufacturing and other industries, helping enterprises improve production efficiency and reduce operating costs. In the future, Zhengzhou Fangkuai Boiler Sales Co., Ltd. will continue to focus on overseas market demands, continuously optimize its product and service system, facilitate the high-quality development of the global textile industry with professional and reliable products, and steadily enhance the brand’s competitiveness and influence in overseas markets.

Trust stems from quality
At the beginning of the new year, Fangkuai Boiler and a leading domestic new energy company have reached another important cooperation, successfully signing an order for a total of 500 steam tons.
