Product Description
AIXBOILER leads China as the top-ranked electric boiler manufacturer with over 45 years of expertise since 1978. Our electric hot water boilers deliver pressurized or atmospheric hot water without combustion, ensuring zero direct emissions, silent operation, and compact design—perfect for urban buildings, hospitals, and eco-sensitive sites.
Since our dedicated electric boiler factory opened in 2020, AIXBOILER has supplied high-performance units to key clients including CNPC, Sinopec, and CNNC. Manufactured in Taikang Industrial Park, Zhoukou City, Henan Province, these boilers achieve efficiencies up to 99.5% and output capacities up to 21,600 kW (equivalent to ~30 MW thermal).
We provide three cutting-edge heating technologies:
- Resistance Heating Type: Immersed electric elements for accurate temperature control.
- Electrode (Electromagnetic) Type: High-voltage current through water for powerful, rapid heating.
- Semiconductor Heating Type: PTC elements for self-regulating, overheat-proof performance.
Ideal for district heating, process hot water, building HVAC, and industrial applications requiring reliable, clean heat.
