As the weather turns cooler, the competition for water heater brands on the market has become more intense. In advertising, there are many different kinds of tricks. As consumers, it is necessary to recognize not only the gimmicks of various advertisements, but also eye-catching insights to identify good products that are truly suitable for themselves. This requires a little common sense and methods. Think of the stainless steel inner liner of the best electric water heater material is how good, all manufacturers in order to attract consumers, but also for the liner to take a good name but also look different on the name of the tank spent all the effort. In fact, the liner material is divided into stainless steel and steel plate. Consumers often have the wrong understanding that stainless steel liners will not rust and corrode. In actual fact, the stainless steel liner has the greatest hidden danger - the weld seam, the melting of the weld seam, the stainless steel material has undergone a fundamental change, is no longer the original stainless steel, I do not see some stainless steel finished weld seam at a long time Will not rust. Welded parts cannot be inspected before leaving the factory. After use or placement for a period of time, the welds will gradually cause water leakage, and the chromium ions in stainless steel are easily corroded by fluoride ions in the tap water. In addition, the cost of stainless steel is relatively expensive, many manufacturers in order to reduce costs, use a relatively thin stainless steel liner, usually only 0. 6 ~ 1. 0mm, pressure capacity decreased, the water heater is more likely to leak, directly affect the life of the water heater. Therefore, in Europe, some developed countries do not use stainless steel as the inner material, and the fact that stainless steel water heaters on the market cannot be used to provide hot water to many places also illustrates that stainless steel is not reliable. Pressure resistance. Another type of steel liner can be divided into resin liner and enamel liner. Crystal silicon liner, gold-silicon liner, glass liner and high-glaze bile, in fact, all refer to enamel, that is, steel plate layer plus enamel layer. The reason why there are all kinds of arguments is just the propaganda arguments of merchants and they want to be different. Enamel is a material that contains silicon metal. It is called enamel in Europe. In the United States, it is called glass. If glass is used as a liner, how can it be under pressure? To know the glass is not brittle pressure. Therefore, only by understanding the truth can we make the right choice. That the most secure water outage power supply Currently on the market that a brand name has launched a new model of electric water heaters, the so-called "water outage, really safe," that is, in the water out of the moment, the electricity is blocked, and truly water separation. In fact, careful analysis, it is not difficult for the wife to present the weaknesses of this product statement: First, if the safety performance of leakage prevention is done well, do we need to spend money on this water outage device? Hydroelectric separation is a device that electric heaters should have, and it is necessary to make up for it only when it is innate. If there is not enough leakage protection measures, then we must design a barrier for the prevention of electric angle. Safety technology is hard and unreliable. Second, because of these devices, the cost of the product must increase. Consumers spend more money on this device and deviate from the safety principles that they should have to buy some so-called safety. If the water heater really needs this device, why not have it at first? Third, frequent switching of any household appliance, including water heaters, will shorten its life span. Moreover, if electricity is cut off during the bath, it means that the electric water heater is no longer heated. Then, as the bath time increases, the water that flows out also increases. It will get colder and colder.
