How much is it to dismantle the water heater?
The electric water heater needs to remove the water pipe with safety valve to drain the water in the water tank, then remove other water pipes and remove the fixing bolts on the wall. The price of water heater is in 200 yuan (price source, for reference only).
Removing the water heater-Steps to remove the water heater
1. First: cut off the power supply of the outdoor unit and unplug the power cord of the compressor. When removing the compressor power cord, it is necessary to mark each power cord and the corresponding terminal so as to restore wiring after maintenance.
2. Then: After the compressor is put in the correct position, pull out the rubber plugs of each interface and immediately weld the connecting pipes (exhaust pipe, suction pipe, gas balance pipe, and the intelligent multi-connected compressor also includes unloading pipe). After the rubber plug is removed, the compressor cannot be left for a long time, otherwise water will enter. When welding pipes, nitrogen filling welding must be ensured, and the nitrogen pressure is 1.0~3.0kgf/cm2.
3. Next, restore the device to the state before replacing the compressor. In addition to fixing the oil temperature sensor and the exhaust temperature sensor in their original positions, insulation cotton should also be used for insulation. After the compressor power cord is installed, power on the compressor to see if it is connected backwards (if it is connected backwards, the compressor will make a dull sound); Once the lubricating oil leaks, it should be added immediately. The lubricating oil of intelligent multi-line is mineral oil, so it is necessary to use mineral oil with corresponding specifications, and the leakage amount is the amount to be added.
4. Finally, the replacement of electronic expansion valve. The throttle device of Angkai water cycle air energy commercial unit adopts electronic expansion valve, and all outdoor units have electronic expansion valves. When it is determined that an electronic expansion valve does have a problem and needs to be replaced, it should be replaced immediately, even if the outdoor unit is not put into use temporarily, otherwise the normal operation of the whole system will be affected.
Deep cleaning of electric water heater disassembly
After introducing the function of sewage outlet, we continue to get to the point. If you want to deeply clean the electric water heater, you must first understand the internal structure of the electric water heater. Usually, when the inner container of electric water heater is compressed, there will be a hole on the side.
Ordinary water heater users certainly have no experience in disassembling electric water heaters, and deep cleaning needs the assistance of professionals.
Main steps of deep cleaning of inner container of electric water heater
1. Stand by: cut off power and water. Let's talk about water discharge here: triangle valve who closes the water inlet pipe (to prevent the water heater from entering the water again) opens the outlet valve of the water inlet pipe (cold water) to discharge water, and the hot water pipe should also be opened at the same time, otherwise the water cannot be discharged. The process of draining water is very long, depending on the impurities in the liner. If there are too many impurities, the time will be longer.
2. Open the cover on one side of the inner tank of the electric water heater, and you will see a hole.
3. Remove the heater gasket, heater (the light yellow cylinder on the lower side is my newly bought magnesium rod, and the screw diameter is 4mm) and thermostat (red head) in turn.
4. Use a container to remove all the scale remaining at the bottom of the lining.
5. Reinstall in reverse according to the disassembly process. It is important to install a heater and press it with a sealing ring to prevent water leakage. In addition, the temperature adjustment knob of the plastic cover should correspond to the knob of the thermostat.
6. Close the drain valve, open the water inlet valve and hot water valve until water flows out of the hot water pipe, then turn on the power supply and adjust the temperature control knob to the appropriate position.
At this point, the deep cleaning inside the electric water heater is over. The cleaned electric water heater can prolong the service life, and at the same time, the heating efficiency is higher, thus avoiding potential safety hazards.
The above is the disassembly method of the water heater for everyone to share in detail. I hope our sharing will be helpful to everyone. Especially those who are engaged in the installation and maintenance of water heaters should pay more attention to what we share. In addition, we also hope that everyone can maintain more water heaters in their later lives and clean them through some methods. If the water heater really has a serious problem that needs to be disassembled, you can refer to the method we shared. If you are disassembling the water heater or feel that you can't disassemble the water heater, you can find a professional to disassemble it. At the same time, I hope our sharing can help more people.
