1. Faucets 2. The 360° outlet pipe rotates and the single handle rotates freely for versatile operation. The handle adjusts temperature; cold water and hot water can be used separately. The hot water temperature is adjusted by controlling the water flow; the smaller the flow, the higher the temperature. 3. Direct heating at the water outlet terminal with low loss during use, saving water and electricity. Water temperature is displayed simultaneously. Hot water is output in about 3 seconds and heats immediately upon turning on, with no need to wait. 4. 3D swirling heating: the waterway wraps the heating tube and the water flow is gradually heated, increasing the heating area, improving thermal efficiency, and saving energy. 5. Flow and pressure dual-start design: sub-zero hot water as usual, resists freezing and does not dry. High temperature protection; low pressure does not start. The heating body is an integrated die-cast unit with no solder joints or joints, providing stable and safer overall sealing. Water and electricity are separated throughout the process for safety and peace of mind. Use scenarios - Kitchen use: instant hot water at the sink for tea, coffee, or cooking, reducing waiting time and eliminating water waste. - Bathroom or powder room: quick warm water for handwashing in cold weather with accurate temperature control to prevent scalding. - Small apartment or office: space-saving instant hot water at the sink, delivering fast heating, energy and water savings, and reliable safety.
