In the event of electricity leakage, the voltage is kept below 12V, ensuring safe bathing.

• Rated Voltage: 240V
• Leakage Voltage: <12V
• Leakage protection achieved through pure physical structure
• Patented Shock Proof Technology included in IEC 60335-2-21

QUALITY

Bubble Elimination Technology

Extends Service Life & Eliminates Safety Risks

An industry-first innovation that ensures uniform temperature distribution, reduces ultra‑high temperature zones, prevents bubble formation, and eliminates the risk of dry burning caused by bubbles.

Comparison:

• Haier Innovation Structure: Uniform temperature field, no large bubbles
• Conventional Structure: Uneven temperature field, prone to localized dry burning

Solid Structure Tank

Withstands 100,000 Pulse Pressure Tests

The nylon fibre solid structure tank enhances pressure resistance and durability, delivering higher quality and long-lasting performance.

• Withstands 100,000 pulse pressure tests
• Test data from Haier Laboratory
