For family safety, it includes a Child Lock function. Once activated, the control panel locks securely, preventing children from altering temperatures or modes accidentally, giving parents peace of mind and worry free daily operation.

When demand is high, the Heat Boost Mode activates another heat cycle at the same power level for faster recovery. Perfect for back-to-back showers or busy households, it ensures continuous hot water before automatically returning to efficient energy-saving operation.

The sleek built-in LCD screen makes control easy and intuitive. Check real-time temperature, modes, and schedules instantly, then adjust settings confidently removing the need for external controllers while keeping operation smooth and simple.

Uses an eco-friendly refrigerant with an extremely low Global Warming Potential (GWP). Safe and non-toxic, it reduces your household’s carbon footprint while delivering strong, reliable performance that’s sustainable and ready for the future.

The programmable timer gives complete control over hot water production. Set heating cycles to match your lifestyle, reduce costs by using off-peak hours, and always enjoy reliable hot water exactly when you need it most, with greater comfort, savings, and convenience every day.
