How to clean a blocked water heater, how to clean a blocked gas water heater

How to clean up the water heater blocked: first check the filter screen of the water inlet, if the copper pipe of the water tank is blocked, switch the water inlet and outlet pipes to connect with each other, and then open the faucet of the water heater for flushing. In case it still doesn't work, remove the water heater, try to pour out the stagnant water in the water heater, dry it for a few days, and then lift the water heater and gently pat the water heater to make the debris inside pour out.

If you still can't clean it well, you can call the after-sales service of the water heater and find a professional to clean it.

If the water heater is clogged with limescale, and the outlet pipe or water tank pipe, you can buy a special scale cleaner from the market to clean it and use it normally.

The way to clean up the blocked water heater is to turn off the water supply valve first, then unscrew the water outlet of the water heater, and the water inlet, or the sewage outlet, and unscrew the water from 2 ports at the same time to make the water discharge in the water heater, and then remove the heater, rinse the inner tank to clean up the scale and rust, and then add salt to prevent scale generation in the inner tank to clean it.

A water heater is a device that turns the temperature of cold water into hot water in a certain period of time through various physical principles. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, air energy water heaters, heating water heaters, etc.

Manufacture of air-conditioning part and manufacture of hot water section. In fact, these two parts are closely linked, inseparable, and must work at the same time. That is, to produce hot water and cool the kitchen at the same time. Or rather, while cooling the kitchen, it is also producing hot water.

At present, after reading the domestic water heater, it is best to ask a professional to clean it, if we clean it ourselves, it is easy to cause damage to the water heater, and it is not safe.

1. If it is just a simple light cleaning, then the user can clean it up by himself. Unplug and place the plug before cleaning to avoid water during the cleaning process. Then rinse with a simple cleaning tool. 2. If it is a gas water heater.

For in-depth and professional cleaning, you can find a special appliance cleaning master to deal with it. Turn off the power before cleaning; During the cleaning process, the dismantled parts are stored in a fixed position to avoid missing or missing; Specialized instruments and high-pressure water cannons are then used.

carry out cleaning; Wait until the water is dry and then install it back and you're done. The reasons for this situation: 1. The reason why the gas water heater will be blocked may be that it has been used for a long time and has never been cleaned, and there is too much dirt accumulated inside it, and it is adsorbed on its inner wall or covered with temperature sensing elements, etc.

2. It is also possible that the drainage pipe or air outlet is blocked. It may be because there is too much debris piled up near it, which affects the smooth airflow and also affects the efficiency of the exhaust. 3. It is also possible that the exhaust pipe is located outdoors and there is no shelter, so when the weather such as strong wind and rain is encountered, some foreign objects are prone to appear inside, which may lead to the blockage of the gas water heater.

Steps to remove limescale from the pipes:

Step 1: Unplug the socket and close the two triangle valves.

Step 2: Unscrew the nut of the hot water inlet and block the hot water inlet to prevent the water from the water heater from flowing out. At the same time, unscrew the nut of the cold water nozzle, connect the hose (shower pipe can be) to drain the water, until there is no water flowing out of the cold water inlet, and the 50L water heater will drain the water for about 1 hour.

Step 3: Remove the hose connected to the cold water inlet, connect the hose to the hot water inlet at one end and the faucet at the other end, open the faucet and fill the water for 1 minute, and plug the cold water inlet, let the cold water in the inner tank for a while longer, then open the cold water inlet to drain the water, and repeat several times until the discharged water is clean.

Step 4: Screw on the nuts of the cold water port and hot water port, open the triangle valve, and turn on the hot water from the water heater faucet, and close it after the water flows out.

Cleaning precautions: Before cleaning, the water temperature of the water heater should be below 50, so that the water temperature can be directly discharged to the sewer pipe without affecting the pipeline. When cleaning, if the water heater has a drain, it can be opened at the same time, because the drain is lower than the cold water vent and the drain is more thorough.

The rate at which limescale is formed is related to the temperature of the water and the flow of water. Water is prone to limescale in the case of high temperature and station, so the above two situations should be avoided as much as possible in use. Don't turn the water temperature up too high:

It is generally believed that scale will be formed when the temperature of water rises to 60 degrees, but the formation rate is slow; When the temperature reaches 85 degrees, the formation of limescale increases. When using an electric water heater, it is advisable to adjust the temperature to between 50 and 60.

It is recommended to discharge hot water after use: after the electric water heater is used, after turning off the power supply, open the tap water valve, let the cold water pass through the circulating water pipe for about 10 seconds, so that the hot water and water vapor in the heat exchange water pipe are discharged, so that there will be no scale in the circulating water pipe, and the components can be cooled in time to prolong the service life.

If you want to unblock the blockage problem of the water heater, you must first unplug the power supply and close the two triangle valves. Then unscrew the hot water spout, nut.

Block the hot water inlet to prevent water from the water heater from flowing out. Unscrew the screw and connect the hose to drain the water until no water comes out of the nozzle. Remove the hose from the cold water inlet and connect one end of the hose to the hot water inlet and the other to the faucet.

Then turn on the faucet and fill the water for 1 minute, and plug the cold water inlet, let the cold water in the inner tank for a while, then open the cold water inlet to drain the water, repeat several times, until the discharged water is clean. Relevant knowledge popularization: 1. Check the firmness of the water heater when using the water heater for the first time, and ensure that the water heater has an independent leakage protection device, and pay attention to emptying the air in the water heater before use.

2. The water heater needs to be cleaned regularly during use, and it is best to clean it every six months to a year, so as to ensure that the water heater can be used normally and can also prolong the service life of the water heater. 3. In addition, it is necessary to conduct a safety inspection of the water heater every year, especially if there are potential safety hazards.

places, to be carefully tested and troubleshooting. 4. For the normal use of the water heater, replace the thermostat at the designated maintenance point every three years.

and heaters. Replace the overdue water heater in time.

Hot water pipes play a very important role in our use of hot water, without hot water pipes, we can't use hot water so conveniently?
