Why must demineralized water be used in hot water boilers?
Tap water or water with a lot of impurities will cause the magnesium ions and calcium ions in the water to form some white precipitates when heated at high temperature, causing scaling problems and reducing the heat transfer efficiency of the boiler. Boiler operation safety brings hidden dangers, even shutdown.
The specific reason why softened water must be used in hot-water boilers is that it will not produce scale in the process of use, so that potential safety hazards of boilers can be avoided, and further, dangers or accidents can be avoided. Therefore, generally in hot water boilers, there will be softened water equipment. If not, scale inhibitor is added to the boiler to achieve the above purpose.
When the boiler is designed, ZOZEN will answer why softened water must be used in the hot water boiler and design a reasonable water treatment configuration to ensure the long-term stable operation of the hot water boiler.

IntroductionIn Wuhan, Hubei Province, Hubei Hanjia New Materials Co., Ltd. and Wuhan Yiqingsheng Building Materials Co., Ltd. required thermal energy equipment for autoclave curing and continuous production-line heating, respectively. Based on the production processes, fuel conditions and site requirements of the two companies, ZOZEN Boiler supplied an 8 t/h DZL series biomass steam boiler and a 7.2-million-kcal YWW series biomass thermal oil boiler. The two projects use different heat-transfer ...03 Nov 2026 -
At Guizhou Haocaitou Food Co., Ltd. in Tongren, Guizhou Province, a ZOZEN WNS series gas-fired steam boiler has been operating for five years as part of the company’s steam supply system. The WNS10-1.25-Q boiler, with a rated capacity of 10 t/h, serves as an important heat source for food production. In recent feedback, the customer noted that matching the equipment configuration to production requirements, along with ease of daily operation and maintenance, were key considerations when se...27 Oct 2026 -
From beverage and convenience food production to rice processing, boiler solutions should be selected according to fuel availability, steam demand and site conditions. Steam is commonly used for heating, sterilization and equipment cleaning in food processing. However, different products, production line configurations and fuel conditions create different boiler requirements. In addition to rated steam capacity, food manufacturers need to consider steam pressure, fuel supply, equipment layout a...20 Oct 2026
