The biggest uniqueness of Midea water heater lies in its patented liner sewage discharge structure. Because the bottom of the water heater is easy to deposit heavy metal impurities harmful to human body, Midea Tech Live Water Heater has made special improvements in this respect, so that users can easily "detoxify" the water heater through DIY, eliminating the trouble of asking the master to clean it regularly.
2. Haier Group
Haier liquid expansion temperature controller, which goes deep into the middle of the inner container to measure temperature, is more sensitive and accurate than the button temperature controller attached to the inner container wall. Haier adopts special formula magnesium rod to reduce consumption and protect the inner container to the greatest extent; The special stainless steel inner core ensures that the magnesium rod will not break. According to the size of the inner container, it is equipped with personalized high-quality magnesium rods, which can weigh up to 3 12g, making it more reasonable and effective to use and prolonging the service life of the inner container.
3. Mr. Smith
A.O. Smith Jingui electric water heater not only can effectively prevent corrosion and scale, but also has outstanding performance in cleaning the inner container of electric water heater. A.O. Smith has successfully developed a patented no-cleaning technology, which can cut off the combination of calcium and magnesium ions and carbonate ions at the atomic level, completely prevent the formation of scale from the source, and the long-term scale inhibition rate is as high as 98%*, basically achieving no scaling.
4. ariston
Ariston heating pipe is made of titanium, with no scaling on the surface, high thermal efficiency and fast heating speed. At the same time, the super anticorrosion performance of titanium gold ensures the long life of heating pipe; The heating tube fully covers the inner container area, with omni-directional and multi-angle, uniform heating without dead angle and faster speed; The heating pipe is closer to the water outlet, and the high-temperature hot water heated by the heating pipe can directly enter the water outlet pipe, which greatly improves the utilization rate of hot water and greatly improves the heating speed.
5. Wanhe
Wanhe electric water heater adopts patented double shielding and adds anti-switching technology on the basis of anti-wall technology. Double shielding not only solves the problem of water electrification, but also solves the safety problem caused by line leakage. The technical principle of anti-switch is that IC chip monitors the live wire, neutral wire and ground wire of the power supply circuit of electric water heater in real time. When any power supply line is abnormal for some reason, the system can cut off the power supply line within 0. 1 second to prevent line leakage.
Matters needing attention in purchasing water heater
1, safety fence.
The reliable anti-leakage protection devices for electric water heaters are anti-electricity wall technology and water outlet power failure technology. Among them, by extending the waterway, the anti-electricity wall increases the resistance of water itself, reduces the current in water and protects human safety. When the water flow reaches a certain scale, the power supply will cut off the water flow to reduce the occurrence of leakage accidents.
2. Life depends on the liner
The service life of electric water heater is as long as 10 years. As an important part of electric water heater, the inner container plays a vital role in the safety performance and service life of electric water heater.
The liner materials on the market mainly include: stainless steel liner, enamel liner and galvanized liner. Among them, the enamel layer of enamel liner is uniform and dense, with strong adhesion, which is superior to stainless steel liner and galvanized liner in corrosion resistance, heat preservation and service life. Therefore, we can give priority to this kind of water heater products when purchasing.
