Product Characteristics (Core Features)

  • ​Rapid Heating Efficiency​​: High-conductivity nickel-chromium alloy core heats 1L of water from 25℃ to 95℃ (optimal usage temp) in ≤30 seconds for 1500W models.
  • ​Multi-Scene Adaptability​​: Power range (1500W-5000W) suits both household tankless water heaters and commercial high-power demand devices.
  • ​Oil-Resistant Corrosion Protection​​: 304/316 stainless steel housing withstands water, steam, and oil contamination (ideal for range hood environments).
  • Точный контроль температуры​: Precision resistance matching ensures ±5℃ water temperature fluctuation (critical for consistent tankless performance).
  • ​High-Temperature Durability​​: Surface operating temperature (150-300℃) balances rapid heating with element longevity; max withstand 350℃.
  • ​Long Lifespan​​: Optimized heat dissipation reduces element fatigue; lifespan extended to 12000h+ with regular oil contamination cleaning.
  • ​Voltage Flexibility​​: 220V (household) and 380V (commercial) options for global users.
  • ​Compact Installation​​: Lightweight structure (≤1.2kg) fits mainstream tankless heaters and range hood heating slots without modification.
