Metal heating element instant heating type Intelligent thermostatic water heater It has been used for more than a hundred years, and its technology is mature and its performance is stable. When working, the heating tube is completely immersed in water, and the heat exchange is rapidly completed depending on the excellent conductivity of the metal tube, with high thermal efficiency. The heating core of stainless steel heating element and copper heating element is the nickel chromium alloy heating wire with stable performance in the world. The only difference is that the materials of the outside and the inside are different.

The characteristics of red copper: soft, easy to stretch and form, acid resistant but not alkaline resistant. Since most of our domestic water is alkaline (more alkaline in coastal areas), it is easy to oxidize to produce copper rust, and the corrosion is more serious when high temperature heats up, which is easy to be broken down by high temperature and generate electric leakage. The pressure bearing capacity of the liner is poor, and it is easy to burst at high temperature.

Features of stainless steel: It has higher hardness than copper, is not easy to deform, is alkali resistant, and is not acid resistant. Because most of our domestic water is alkaline, it is not easy to be oxidized. Low heat loss rate, uniform heating, good pressure resistance, good heat expansion and cold contraction.

Separation of water and electricity: In contrast, the instantaneous intelligent thermostatic water heater, due to its high requirements for lines, mostly uses the heater water and electricity separation technology, which is equivalent to the use of both the previous two anti electricity technologies. This is a safe way at present. By Electric water heater The selection of the material (insulation material) of the inner water pipe, the determination of the pipe diameter and distance form a "diaphragm wall". When the electric water heater is powered on, even if there is electricity, the water in the heating body will be attenuated by the resistance of the water itself when it passes through the "electric wall" to achieve the purpose of electrical isolation. Then, air switches and ground wires will be equipped to make the water heater conduct heat but not conduct electricity, truly achieve complete separation of water and electricity, protect the external installation environment, and truly achieve safety!
