The importance of using a wall water heater or even a tank water heater makes it very important to service and repair it. The service and repair of a wall water heater is different from the service and repair of a tank water heater due to its type of structure.
Due to the importance of this issue, we previously wrote in an article entitled "What factors cause the water in the water heater to not heat up?" "We investigated and stated the main problems facing water heaters that cause their water not to heat up and named 4 cases, which were the following: 1. Clogging deposits of consumer converter 2. Non-steadiness of candle flame 3. Dirty device unit 4. Rupture and failure of the diaphragm washer Of the above, naturally, the issue of sedimentation plays the biggest role in not heating the water in the water heater. Therefore, when servicing and repairing wall-mounted water heaters and even tank water heaters, it is necessary to pay special attention to this issue and act on descaling by observing several principles. If we do not follow a principled method during descaling, problems will definitely arise for the water heater.
Multi -Wallpaper Disinfection Tips
Many times, even though all the necessary tips are followed to prevent sedimentation in the wall water heater, the main exchanger gets sedimented. In such a situation, in order to carry out basic descaling and to prevent other damage to the device, it is necessary to consult and help from experts or reputable service and repair centers for wall-mounted water heaters.
Factors of sedimentation in wall water heater
Sedimentation of the water heater pipes reduces the diameter of the pipes and also by making the wall of the heat exchanger of the water heater thicker, it reduces the heat transfer from the flame to the water. This reduction in thermal conductivity, in turn, causes loss of thermal energy and damage to the outer wall, as well as noise in the pipes. Another cause of clogging of the heat exchanger tube is the spot heating of the heat exchanger tube at the top of the spark plug, which in some cases cannot be removed even with anti-scalding materials, and we have to cut the tube and re-weld it. One of the reasons for removing the candle in new models of wall water heaters is to solve this problem. Adjusting the flame of the candle and turning it off when not in use for a long time can have a significant effect on improving the performance of the water heater.
If the candle is not in order and the wall water heater is not descaled, you will need descaling every three months. Penetration of welding materials when welding the U-shaped elbows of the heat exchanger can also cause deposits by creating resistance.
Deconstructive materials
To remove deposits inside the heat exchanger, hydrochloric acid or 20% salt ink is used. Always store these materials in closed containers so that their toxic vapors do not cause respiratory problems and be careful not to spill them on other surfaces.
