In the instant hot electric water heater, its four schools mainly refer to four different heating technologies, which mainly refer to the “metal tube” school, “glass tube” school, “cast aluminum” school and “semiconductor ceramics” school.
Metal pipe: It mainly refers to the main heating element of the water heater is composed of metal, metal heating tube materials on the market are mainly stainless steel, copper, etc., of which copper this material has good ductility, so it can make seamless copper tube, while its thermal conductivity is also very strong, in the process of use can also prevent the occurrence of water leakage and leakage phenomenon. However, the cost of water heaters made of copper will be relatively higher, so most companies are directly using stainless steel tubes. Metal heating tube is now the most used one, although its advantages are very outstanding, but in use it can not avoid the emergence of structural problems, so it will easily bring leakage, water leakage hidden dangers.
Glass tube: Non-metal heating tube on the market is mainly made of crystal, glass, ceramic these three materials, glass tube school its advantage is the resistance film smeated on the outer wall of the glass tube, when the water flow through the glass tube, water and electricity will be fully separated, so that the safety performance can be more guaranteed, but the use of glass made of a kind of material made of heating tube its thermal conductivity is relatively poor. Therefore, in the process of heating, it is easy to waste heat energy, and at the same time, in the case of extremely hot and cold, it is also easy to cause the glass tube to burst.
Cast aluminum tube: The cast aluminum tube can achieve complete isolation between the waterway and the heating element when in use, the water flows in the pipeline gradually heating up, effectively avoiding the scale problem that is easy to bring about by high temperature still water heating, so it will not produce scale when in use, then the service life of the heating tube is also effectively extended. Its disadvantage is that the heating body is too heavy, while the production process is more complex, the production cost is high, so it has not been widely promoted.
Ceramic pipe: Ceramic pipe in the use of the process to completely solve the problem of dry burning caused by fire, through the pipe heat transfer, it can also achieve permanent isolation of water and electricity, water flow pipe and ceramic are completely separated, the water pipe finish is higher, so there is no burst pipe and water leakage problems. However, the ceramic tube is relatively slow when starting heating in the process of use, and the heating pipe of this material is also more expensive.
