Metal heater Electric 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.
Hydroelectric separation: by contrast, i.e. thermal Intelligent thermostatic water heater Due to the high requirements for the line, most of them use the heating element water electricity separation technology, which is equivalent to the use of both the previous two anti electricity technologies. This is a safe way at present. Through the selection of the material (insulation material) of the water pipe in the electric water heater, and the determination of the pipe diameter and distance, a "partition wall" is formed. 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!
Electrified water resistance method: when the electric water heater leaks electricity, the power supply is not cut off, but a plastic pipe is added at the water inlet and outlet pipes of the water heater, which is equivalent to installing a series resistance between the human body and the water. In case of leakage, it can share most of the voltage, so that the voltage borne by the human body is reduced to below 12V, and there is no feeling of electric shock.
Power off method: The principle of the new power off method is to quickly cut off all connections with the power supply, including the live wire, zero wire and ground wire, when the external grounding of the electric water heater is abnormal, so that the bathing environment is completely without power, so as to achieve the goal of safety. This principle is mostly used for water storage leakage, such as the leakage protection we see.
The quality of Zhongshan Wanmite Electric Appliance Co., Ltd. has been for many years. The heating body uses V10 die-casting aluminum for intuitive heating. There is no bending process, no power loss, and no scaling. This determines that the service life of the water heater is longer, namely, it is hot when it is turned on. Every kilowatt hour of electricity delivered by computers is almost transformed into thermal energy, and each kilowatt hour of electricity is efficiently used. The internal and external seals are sealed, and waterproof and silent design is adopted, Intelligent frequency conversion control, enjoy bathing, automatic adjustment function, and constant temperature water outlet.
