1. Energy ecient, instantaneous heating on demand. It's tankless, so no preheating
and no stand-by heat loss, which saves even more energy.
2. Micro-computer controlled, patented heating technology.
3. Extremely safe! Water is completely separated from electricity by multi-layers of
composite nano-insulation material, and the heater contains multiple additional safety
devices, as outIined below.
4. Over-heating treaches 153° F / 67°C, the electricity is automatically cut o. If this
occurs, the screen hermal cut-o to avoid scalds. When the outlet water temperature
beeps and displays an E1 code.
