This product has no water storage and preheating, to provide a simple and reasonable structure, high efficiency and safety, with reliable performance and long service time. Multifunctional design, with automatic temperature control function, over temperature protections, and leakage protections. Both ends of the waterflow heating channel of the main body are provided with a water inlet joint and a water exiting joint. The value of waterflow through the heating channel is less than the initial value. It will not heat up the waterflow, avoids dry burning and avoids potential safety hazards, prolong the working lifespan, and realize energy saving and high efficiency. Features: The water heating device is small and compact and does not take up space. Easy to install, IPX4 waterproof, the body is fearless of water droplets splashing, suitable for bathroom, kitchen, and other occasions. Reinforced stainless steel heating core, high-power heat conduction, fast heating, constant temperature, continuous supplying, more comfortable to use. No need to store water, no need to preheat, no need to repeatedly heat insulation, energy saving and power saving. LCD large screen temperature display, the water temperature will be displayed in real time, visible temperature is more assured. Automatic temperature control, the temperature value detected by the sensor exceeds the set temperature range, the enclosure will automatically stop heating, lower than the set temperature, and automatically resume heating. Separation of water and electricity, internal and external anti-electricity wallx design, water and electricity are not connected, prevents water and electricity leakage, safer to use. Multi-protections design, over-temperature protections (water temperature exceeds 90 degrees intelligent cut off the power supply), dry burning protections (bimetallic mechanical switch prevents the electric heating tube burned out), grounding protections (avoids strong current through the human body when the insulation is damaged). Adjustable water temperature, equipped with a water temperature rotary switch to control the water temperature, the more you turn to the right, the higher the temperature is.
