What is the electric water heater heating pipe? Electric water heater heating tube replacement

The water heater heating pipe is one of the important parts of the electric water heater. Therefore, we need to know the material of the heating pipe when purchasing the electric water heater. So what is the electric water heater ? How to replace the electric water heater heating pipe? Let's take a look at the decoration home decoration network Xiaobian.

What is the electric water heater heating pipe?

Electric water heater heating tube material 1, metal tube: It mainly refers to the main Heating Element of the water heater is made of metal. The material for making metal heating tube on the market mainly includes stainless steel, copper, etc., among which copper has a good extension. Sex, so it can make a seamless copper tube, and its thermal conductivity is also very strong, it can also prevent leakage and leakage during use, but the cost of using a copper water heater will be relatively higher. Therefore, most companies use heat pipes made of stainless steel directly. The metal heating tube is the most used one. Although its advantages are outstanding, it can not avoid the structural problems when it is used, so it is easy to bring hidden troubles of leakage and water leakage.

Electric water heater heating tube material 2, ceramic tube: The ceramic tube completely solves the problem of fire caused by dry burning in the process of use. Through tube heat exchange, it can also realize permanent isolation of water and electricity, and the water flow pipeline and ceramic are completely separated. The water pipe has a higher finish, so there is no problem with squibs and water leaks. However, the ceramic tube is slower when it is just started to heat up during use, and the heating tube of this material is also more expensive to manufacture.

Electric water heater heating tube material 3, glass tube: The non-metal heating tube on the market is mainly made of three materials: crystal, glass and ceramic. The advantage of the glass tube is that it applies the resistive film on the outer wall of the glass tube. When passing through the glass tube, the water and electricity will be fully separated, so that the safety performance can be more guaranteed. However, the heat-generating tube made of glass type material has poor thermal conductivity, so it is easy to cause heat during heating. The waste, while in the case of extremely cold and extremely hot, it is also easy to cause the glass tube to burst.

Electric water heater heating tube material 4, cast aluminum tube: cast aluminum tube can achieve complete isolation between water circuit and heating element when used, water gradually heats up in the pipeline, effectively avoiding the scale caused by high temperature hydrostatic heating The problem, therefore, does not produce scale when used, and the service life of the heating tube is effectively extended. The disadvantage of the cast aluminum tube is that the heating element is biased, and the manufacturing process is complicated and the production cost is high, so it has not been widely promoted.

Electric water heater heating tube replacement steps:

The water heater heating pipe is one of the important parts of the electric water heater. The details that need attention when replacing it are also the most. Carelessness will cause problems such as water leakage and insufficient hot water.

1. After the power is cut off, remove the maintenance cover at the right end of the casing, and take a photo with the mobile phone to save the wiring method of the connecting line.

2. Unplug the high temperature cable of the circuit with a tool such as pliers.

3. Use a wrench to remove the five nuts of the heat pipe cover and then rotate the cover counterclockwise to remove the heat pipe.

4. Put the new heating tube on the sealing ring.

5, when the screw is replaced, it should be fixed diagonally, otherwise the installation will cause leakage.

6, pay attention to the end of the heating pipe bend must be toward the nozzle side, otherwise it will cause insufficient hot water.

The above is the electric water heater heating tube that Xiaobian brought to you. The entire contents of the electric water heater heating tube replacement, I believe that everyone has a basic understanding of the electric water heater heating tube after reading this article, if you want to know more about the decoration consultation, please click to enter the decoration knowledge channel .
