Gas-fired hot water boilers are used very frequently in our daily lives, and domestic heating and hot water supply are inseparable from it. For boiler equipment, good and effective maintenance can not only improve the use efficiency of gas-fired hot water boilers, but also extend its service life; then what effective methods should be used for maintenance?
1. Pressure maintenance
This kind of maintenance method is suitable for boilers that are out of service but short-term maintenance does not exceed one week. You can drain all the water in the boiler first, then clean up the scale in the boiler in time, and re-add qualified softened water; use a warm fire to heat it regularly to keep the water temperature in the gas hot water boiler at ten degrees in summer In winter, it is guaranteed not to freeze; water must be supplied to the boiler regularly to keep the pressure in the boiler at a normal value to prevent air from entering the drum.
2. Wet maintenance
This kind of maintenance method is suitable for gas-fired hot water boilers that have been shut down for no more than one month. After stopping the boiler, the boiler water should be drained according to the specified time, and the impurities inside should be cleaned up; secondly, all inlets and valves should be closed to completely separate it from the running boiler; and the prepared mercury should be used. Alkaline protection solution is put into the boiler; during the entire maintenance period, the oven should be regularly used with a low fire to keep the heated surface dry.
3. Dry maintenance
Dry maintenance is suitable for gas-fired hot water boilers that have been shut down for a long time. It is also necessary to drain the water and remove impurities. Secondly, it must be completely isolated from the running boiler; use an appropriate amount of desiccant to absorb moisture in the boiler, and at the same time, the desiccant must not be in direct contact with the heated surface of the boiler ; Within one month, it should be checked whether the desiccant will cause corrosion in the boiler.
The above is the method of maintenance of gas-fired hot water boiler from three aspects summarized by the Zhengzhou Fangkuai boiler manufacturer. The boiler factory also emphasizes that regular inspections should be carried out when the boiler is used, and special attention should be paid to the corrosion of the boiler. Ignoring the problem of corrosion will have unpredictable serious consequences.
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.
