Constant Power Output & Whisper-Quiet Operation

Through Inverter Pulse Width Modulation (PWM), power output remains perfectly stable, maximizing heater lifespan and ensuring consistent heating performance.

Operating with virtually zero noise, it delivers a quiet, comfortable living experience.

Built-in 3-Way Valve

  • Dual Heating & Hot Water: Precision flow redirection via the built-in 3-way valve works seamlessly with an indirect tank to supply both central space heating and domestic hot water (DHW).
  • Lower Installation Costs: Factory-integrated design eliminates external valves and complex piping, significantly reducing labor, time, and material costs.
  • Superior Reliability: Minimizes external pipe connections and wiring errors, drastically lowering leakage risks and overall system failure rates.

Integrated Hydronic Component System

Equipped with a high-performance expansion vessel and premium circulation pump to ensure optimal system pressure stability and reliable water circulation.

Innovative Heating Element with Water & Electricity Separation

Delivers exceptional safety and system stability. Designed with over 98% heating efficiency that remains consistent over prolonged use, backed by a 15-year design lifespan for long-term operational reliability.

Intelligent Control, Built-In Safety

Smart technology for reliable, efficient, and worry-free heating.

  • Smart Anti-Freeze Guard: Auto-activates at ≤5°C to prevent freeze damage to the boiler and piping system.
