For users who need to use a vacuum hot water boiler, the selection of the boiler is a very critical step, which is related to the use and maintenance of the boiler in the later period. If you buy inappropriate boiler equipment, you will not only need to purchase a second time. This leads to increased input costs and delays the project construction period. So, what issues should be paid attention to when selecting a vacuum hot water boiler? Let Zhengzhou Fangkuai Boiler Factory tell you the answer.
1. Fuel selection for vacuum hot water boiler:
Fuels such as natural gas and liquefied petroleum gas are common fuels used in vacuum hot water boilers. Zhengzhou Fangkuai Boiler Factory recommends that users give priority to natural gas and regenerated oil, which can be used for both petroleum and natural gas (special order).
2. Load selection for vacuum hot water boiler:
This requires a certain understanding of the application field of vacuum hot water boilers, because the heating load selection of any building cannot be budgeted. This data has a great relationship with building insulation and indoor use, but it has a small relationship with the building area. relationship.
3. For the pressure selection of the vacuum hot water boiler:
If you want the vacuum hot water boiler to output warm water and sanitary hot water, the pressure of the boiler is 0.8 MPa, and the pressure of the parts is 0.81~1.2 MPa, and the parts are recommended to use high-pressure devices. If the pressure is 1.21 ~ 1.6 MPa, the fragmented and comprehensive element should be based on economic and technical analysis to use the ultra-high pressure unit type, or stop the secondary heat exchange. If the pressure is above 1.6MPa, it is recommended to design two heat exchangers for the vacuum hot water boiler.
4. For the location selection of the vacuum hot water boiler:
The unit of the vacuum hot water boiler runs smoothly, with almost no vibration and low music. The location of the machine room is very convenient. The basement, air, floor, and roof can be used as a machine room. If it is used in a high-rise building, in order to reduce the unit pressure, the boiler room should be set in the middle or the top of the floor.
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:
