[Safe material]: The hot water faucet is made of food-grade 304 stainless steel, and the internal anti-electricity wall design ensures that water and electricity are blocked and prevents water and electricity leakage. Quick Heating: The heating faucet adopts a three-dimensional rotating heating design. The heating core is made of 304 stainless steel, which heats up quickly, is wear-resistant and corrosion-resistant, does not produce patina, and is not easy to produce scale. LED Display: The heating faucet adopts LED display, which can visually see the temperature change, the data is accurate, convenient and fast, suitable for home use. [Safety Design]: The heating faucet adopts two separate circuits of water and electricity to avoid leakage problems. The product has multiple safety protection designs such as dry-boiling protection, explosion-proof protection, overvoltage protection, grounding protection, and overheating protection, providing you with a safe and stable use environment. Overheating protection (water temperature exceeds 90, intelligent shutdown); anti-dry protection (bimetal mechanical switch to prevent electric heating tube from burning); grounding protection (to prevent strong current from flowing through the human body when the insulation is damaged). [Precautions]: The tap water of the input method is the bottom water inlet, and the diameter of the interface is 1/4. When installing, the faucet can only be installed upright, and the water pressure is required to be 0.04~0.6MPa. If you have any questions, please contact us in time.
