Key Features

  • 6.2-star energy rating

    Independently rated for gas energy efficiency — reducing energy consumption and lowering running costs.

  • Endless hot water on demand

    Continuous flow design with no storage tank to run out — hot water whenever you need it.

  • FlameSustain™ technology

    Maintains stable combustion even under low gas pressure, low water pressure, or high wind conditions.

  • Customisable temperature

    11 set points from 38°C to 75°C, factory preset at 50°C for safety and comfort.

  • WaterServo technology

    Minimises water wastage by rapidly delivering hot water and maintaining consistent temperature with precise flow control.

  • Advanced safety protection

    Dual CPU protection with intelligent self-check system. Guards against gas pressure fluctuations, overheating, accidental flameouts, voltage overcurrent, and burnthrough.

  • Anti-freezing protection

    Built-in 100W anti-freezing heating capacity protects the unit in cold conditions.
