Why does the gas-fired hot water boiler have the problem of slow heating?
1. Because gas hot water heating boiler is used for central heating, after the boiler is ignited during heating, a series of processes such as furnace heating, low-temperature operation and heat exchange are needed, to gradually heat up the central heating. After ignition of gas-fired hot water heating boiler, furnace heating is a necessary preparation work at the initial stage of heating every year, and this process takes about 3-5 days to complete.
2. In the process of use, the gas-fired hot water heating boiler also needs to undergo the process of heat exchange, so that the temperature can gradually rise. The heat exchange process of gas-fired hot water heating boiler is mainly the process of water circulation. The hot water from the heating station is not directly circulated to the heating pipe network of residents' homes, but needs the heat exchanger unit to transfer the heat energy of the hot water in the heating station to the circulating pipe network of residents' homes.
3. At the initial stage of boiler heating start-up, the outlet water temperature of each heating station is not very high, and the structure of the pipe network is complicated, so the hot water heat exchange of gas-fired hot water heating boiler needs a process, especially for users at the end of the pipe network, the process time of heat exchange will be longer.

From spinning and weaving to dyeing, printing and heat setting, steam is required throughout multiple stages of textile production. As textile enterprises pay closer attention to energy costs, steam supply stability and emission requirements, boiler selection can no longer be based solely on rated evaporation capacity. Local fuel availability, production load, boiler room conditions and ongoing operation and maintenance also need to be considered. Recent textile projects served by ZOZEN Boiler ...10 Nov 2026 -
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
