Haier water heater cold water, big hot water, small hot water is what s going on

The material shows that the long-term use of the water heater without cleaning causes the internal dirt blockage of the machine, which is the main reason for the small water output of the water heater.

In view of this situation, the technicians of the water heater maintenance center suggest that the water heater should be cleaned and maintained once between 6 months and 1 year, which can effectively extend the life of the water heater and reduce the occurrence of such failures.

1. The water pressure of the tap water at home is very low; Solution: Ask a professional water heater maintenance personnel to add a booster pump.

The method of judging the pressure: turn on the shower of the water heater to the maximum, and completely pull the mixing valve to the cold water end, observe the water output and test the water pressure, and then rotate to the hot water end until it is completely turned to the hot water end, and observe the change of water volume and water pressure.

If the overall water output is small and the water pressure does not change much, it should be preliminarily judged that the water pressure is low, and the installation of a booster pump can be considered; If the water output is large at the cold water end and the hot water end is small, it should be judged as a plug and water heater cleaning should be prioritized.

2. If the water heater is not cleaned for a long time, resulting in internal blockage of the water heater, the water heater cleaning personnel should be contacted to clean the machine.

3. The shower is dirty and blocked; Clean up blockages or replace showers.

1. It is related to the diameter of the water pipe used to install the hot water outlet pipe (to summarize the size of the house, it is normal to use four or six water pipes, if it is a large house, it is recommended to increase the water pipe;

2: There may be a blockage in some water pipes in the hot water pipe, and you have to call a professional to clean it;

3. Maybe in the process of hydropower decoration, the plumber did not pay attention to the protection work, and there were small sand particles falling into the water pipe, the longer the time, more and more scale in the water pipe stopped in the water pipe, so the hot water will get smaller and smaller, and even no hot water will come out;

4. Check whether the main water pipe switch of the outlet part of the water heater is adjusted to the maximum or in the middle part;

5. The reason for the small amount of hot water is that there are small sand particles in the water pipe and rush into the filter screen of the flower umbrella water outlet, which has to be removed and cleaned.

The water heater has a lot of cold water and very little hot water for the following reasons:

1. The heating efficiency of the water heater heater is low, and it cannot support direct heating with large amounts of water.

Solution: Replace the high-power heater.

2. The hot water outlet pipe is blocked by scale after being used for a long time, resulting in slow water discharge.

Solution: Replace the hot water outlet pipe or clean the hot water outlet pipe.

Most water heaters produce water slowly due to clogged pipes, and cleaning up the limescale accumulated in the pipes can greatly improve the speed and efficiency of water discharge.

The hot and cold water of the water heater is very small, it may be that the water pipe is blocked, check the water inlet filter of the water pipe, and check whether there are any impurities. It's good to have impurities cleaned up.

The abnormal water volume and temperature of the water heater may be caused by scale due to the use of the water for too long or the water quality problem. When there is a large amount of scale and impurities on the pipes of the water heater, it will be clogged and affect the speed and temperature of the water output. How to solve the problem of large hot water and small hot water in the water heater:

If the water heater is abnormal in cold and hot water, first consider whether it is due to the plumbing. The outlet pipe can be removed and cleaned to remove the scale and impurities that are clogged in the pipe. If the pipe is too old or has problems with itself, the pipe can be replaced.

This increases the rate at which the hot water is discharged. The internal plumbing of the water heater is complex, which may affect the efficiency of the hot water output. When using the water heater, turn on the hot water tap to the maximum.

Wait for the hot water to come out and then slowly adjust to the right temperature. In this way, the amount of hot water will be larger. When the cold water pressure is greater than the hot water pressure, resulting in the hot water volume being less than the cold water volume.

We can artificially reduce the pressure of the cold water, such as blocking the cold water inlet. In this way, when the pressure of hot water increases, the speed of hot water will naturally increase. The triangular valve of the water heater can also affect the water pressure, water outlet, etc.

When there is an abnormal water volume, you should also check whether the triangle valve is opened to a normal state, whether it is fully opened, and the triangle valve can also adjust the water pressure.

Causes and solutions:

1. The water pressure of tap water is too low.

The method of judging the pressure: open the shower and inlet valve of the water heater to the maximum, and completely place the mixing valve at the cold water end, observe the water output and test the water pressure, and then rotate to the hot water end until it is completely placed at the hot water end, and observe the change of water volume and water pressure. If the overall water output is small and the water pressure does not change much, it should be preliminarily judged that the water pressure is low, and the installation of a booster pump can be considered; If the water output is large at the cold water end and small at the hot water end, it should be judged that the inside of the water heater or the pipe is blocked, and the cleaning of the water heater should be prioritized.

Solution: If the water pressure is too low and the water output is small, it is recommended to ask a professional maintenance personnel to add a booster pump.

2. The inside of the water heater is blocked.

The water heater has not been cleaned for a long time, and the internal blockage of the water heater leads to the failure of the water heater with small water output.

Solution: It is recommended to contact professional water heater maintenance personnel to do a comprehensive cleaning and maintenance of the water heater.

3. The water heater nozzle is blocked.

Solution: The water heater is small due to dirty and blocked sprinklers, so clean up the blockage or replace the sprinklers.

4. The filter screen of the water heater inlet is blocked.

Solution: There are many blockages on the filter screen of the water heater inlet, and the blockage on the filter screen can be cleaned off.

Summary. Hello, the common reasons for the occurrence of cold water in the water heater are usually very small: 1. The heating efficiency of the water heater is low, and it cannot support direct heating with a large amount of water. 2. The hot water outlet pipe is blocked by scale after being used for a long time, resulting in slow water discharge.

3. Secondly, there may be a problem with the safety valve of the water heater, if the safety valve does not exhaust when the water is heated by the inlet water, the internal pressure of the water tank is insufficient, and the hot water cannot be produced smoothly.

Solution 1: Replace the high-power heater. 2. Replace the hot water outlet pipe or clean the hot water outlet pipe.

Personally, it is recommended that the scale in the water heater tank should be cleaned regularly, otherwise it will lead to the accumulation of rust stains that will block the filter screen of the water outlet, and it will also cause one of the reasons for the slow hot water output. The magnesium rod has absorbed too much limescale, so it heats up slowly, and even hot water does not come out. In addition to the outlet pipe, the filter screen and magnesium rod of the water heater should also be cleaned, which can not only solve the problem, but also improve the efficiency of the water heater.

However, the cleaning work can be carried out by the cleaning master.

How to clean the hot water outlet pipe.

Water heater hot water pipe scale cleaning method: 1Turn off the power of the electric water heater.

2.Turn on the hot water faucet to drain the water, open the pressure relief valve and close the cold water valve. 3.

Find the outlet, remove the magnesium rod and drain the internal sewage. 4.Inject the cleaning agent into the drain with a syringe and open the cold water inlet valve to soak.

5. Heat for a period of time, unscrew the drain nut to remove sewage. 6.After draining the water, rinse it repeatedly with cold water.

1. The reason why the cold water in the water heater is very large and the hot water is very small:

1. The heating efficiency of the water heater heater is low, and it cannot support direct heating with large amounts of water.

2. The hot water outlet pipe is blocked by scale after being used for a long time, resulting in slow water discharge.

2. Solution:

1.Replace the hot water outlet pipe or clean the hot water outlet pipe.

2.Most water heaters are slow to produce water due to blocked pipes, and cleaning up the scale accumulated in the pipes can greatly improve the speed and efficiency of water discharge.

3.There is a finger-thick, vertical tube inside the tank, slightly shorter than the diameter of the tank, the top is open, when the handle is turned to the hot water valve position, a large amount of cold water is squeezed in from the bottom, because the cold water density is high, the hot water density is small, so the top always gathers the water with a higher temperature.

4.The hot water is forced by the cold water to enter from the top of the hot water pipe mentioned above, and the other end of the hot water pipe is connected to the shower. Come out with hot water for you to use.

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 the different principles of noise, 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.

Working principle: A complete household multi-functional water heater contains 2 main parts: its internal structure is mainly composed of four core components: compressor, condenser, expansion valve, and evaporator.

The working process is as follows: the compressor compresses the refluxed low-pressure refrigerant into high-temperature and high-pressure gas flowing through the pipeline, and the high-temperature and high-pressure gaseous refrigerant flows through the copper pipe wound outside the water tank, and the heat is conducted into the water tank through the copper pipe for heat exchange, and the cooled gaseous refrigerant becomes liquid under the continuous action of pressure, and enters the evaporator after the expansion valve.

At the same time, under the action of the fan, a large amount of air flows through the outer surface of the evaporator, and the energy in the air is absorbed by the evaporator, and the air temperature decreases rapidly, turning into cold air and discharging into the kitchen. The refrigerant, which has absorbed a certain amount of energy, then flows back to the compressor and enters the next cycle.

From the above working principle, it can be seen that the working principle of the household multi-functional water heater is similar to the principle of air conditioning, and the inverse Carnot principle is applied, by absorbing a large amount of low-temperature heat energy in the air, it becomes high-temperature heat energy through compression of the compressor, and is transmitted to the water tank to heat up the water.

The reasons why the hot water in the water heater is particularly small are: the hot water pressure is not enough, the hot water faucet is blocked, and the water from the shower is problematic.

1. When the hot water pressure stored in the water heater tank is insufficient, then we will find that the hot water output is very small when we open the hot water faucet. In this case, we can install a booster pump at home to increase the water pressure, and then solve the problem of small hot water output from the electric water heater.

2. In daily life, it is difficult to avoid all kinds of dirt entering the hot water faucet, which will lead to the blockage of the hot water faucet, in which case the hot water output of the electric water heater will be small. We can use a sharper tool to clean the faucet, if we can't clean it thoroughly, we can directly replace the faucet.

3. When there is a problem with the water output of the water heater shower, it will also lead to a small amount of hot water output from the water heater. At this time, we first have to check whether the shower is blocked, if it is a blockage, we can use a fine needle to dredge, if the shower is broken, we can directly replace the shower.

When using a water heater, you need to pay attention to:

1. If you are using a gas water heater at home, then you must pay attention to safety issues. Once the leakage of liquefied reed gas occurs, it is likely to cause very bad consequences, so you should regularly check the gas water heater for gas leakage.

2. The use of water heater is also to pay attention to the situation of cold and hot water back, in this case, if the hot water flows through the cold water pipe, it is likely to cause the water pipe to rupture, if we get too close, the hot water splashes out is likely to burn us.

3. If the water heater fails, and we don't have any experience in maintenance, it's best not to try it yourself, otherwise it is likely to make the damage more serious, and you should ask a professional master to help repair it.
