Winter is the peak period for using hot water boilers. Most northern cities use hot water boilers for heating and domestic water supply. However, Zhengzhou Fangkuai Boiler Factory found that many heating companies ignored the antifreeze work of boilers in winter, which led to failures and losses. Let’s talk about what protective measures should be taken when hot water boilers are used in winter.
For the hot water boiler system, the temperature is low in winter, the first thing to do is to prevent freezing of the entire system of the boiler. When the temperature of the water tank is low, pay attention to prevent freezing and cracking. Compared with outdoor boiler equipment, this also shows the boiler The advantage of the room.
Secondly, when the hot water boiler system or auxiliary equipment encounters a failure, it is necessary to stop the system, check and eliminate the problem, remove the water and wastewater in time, and open or close the valve according to the specification.
There is also the piping problem of the hot water boiler. It is necessary to do a good job of anti-freezing of the cold water pipe to avoid freezing, which affects the overall operation of the boiler system. In addition to regular inspections of the steam boiler, the operating conditions of the auxiliary equipment of the system should also be checked to ensure that the boiler can also provide heating and heating normally in winter.
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:
