Why does the gas water heater go up and down?

Reasons why the water temperature of gas water heaters fluctuates from high to low:

Most of the water heaters in this situation are because there is too much scale, which makes the water flow in the water pipe sometimes large and sometimes small, resulting in the situation that the water is cold and hot;

The internal dirt and blockage of the gas proportional valve cause the uneven gas supply, which will be large and small, so that the heat of the fire discharge will change with a large and a small time, resulting in the phenomenon of cold and hot when the water is discharged;

The water pressure at the inlet end fluctuates greatly, causing the water flow to be large and small, and finally make the hot water in the outlet pipe cold and hot;

The amount of water is damaged, the control valve is damaged or dirty, and the water flow is unstable, sometimes large, sometimes small, resulting in the phenomenon of cold and hot when the water is out.

Solutions to the above problems:

To clean up the scale, the water heater is very simple to clean the scale, no need to buy any descaling equipment, the gas water heater only needs to be poured into the water tank with edible vinegar mixed with water to soak for one night; The electric water heater only needs to clean the internal water tank with a special detergent, and then replace the iron rod;

If the gas proportional valve is dirty, it can be removed and cleaned inside, and the small gasket and spring should not be lost during installation;

If the water pressure at the inlet end is unstable, an adjustable pressure stabilizing pump should be purchased to solve this situation;

If the water volume control valve is damaged, it can be replaced directly, if it is blocked or dirty, it can be disassembled, the inside can be cleaned and replaced.

Precautions: Before disassembling and replacing accessories, disconnect the air source, water source and power supply to ensure safe operation. In addition, gas water heaters, like gas stoves, must be repaired by professionals in time when there is a non-ignition failure, otherwise it is easy to cause accidents.

The water temperature may be caused by the instability of water pressure or air pressure, if it is determined that the water pressure and air pressure are stable, it is a problem with the machine, it is recommended to contact the manufacturer for after-sales inspection and processing.

This one needs to be adjusted. There is also this situation in my house, and then this situation occurred in less than half a year when I bought it, and then I called ** to the person who installed it, and then asked him to help in time, saying that then we got it ourselves, you didn't get it yourself, and he came to help get it, well, if your family has just bought it not long ago, you can um, let him still be within the warranty period, and then you can help him help you get it or after the warranty period, you can consult him about it yourself, you can't get it, and then find a knowledgeable person to help.

The temperature of the heat exchange surface of the water heater is very high, and there will be scale when the water flows over, and after a long time, there will be a lot of scale attached to the inner surface of the heat exchanger, which will accumulate over time, resulting in the blockage of the hot water pipeline, which will cause the hot water output to become smaller (the phenomenon of small water pressure) and the hot water output time will become longer. At the same time, the hot water outlet is equipped with a temperature sensor, which is the narrowest place in the water heater waterway, which is easy to accumulate scale, resulting in temperature sensing lag, resulting in hot and cold water outlets, and serious hot water overheating, causing overheating protection to go out. It is recommended to clean and descale first, buy a set of fast water heater without removing the scaler, use it to inject descaling agent into the water heater to clean the inside of the water heater can be solved, the operation is simple and convenient, use it to clean it regularly, when this problem can be avoided again.

In addition, 1Unstable cold water supply pressure will cause the water temperature of the gas water heater to be unstable, check whether the filter screen is dirty, if the pipe is blocked will affect the water temperature, you need to remove the scale regularly. If you find that the pipeline is not blocked, you can add a water pump to stabilize the pressure.

2.The unstable pressure of the gas supply will cause the water temperature of the gas water heater to be unstable, check whether the gas is stopped, if the gas is stopped, go to the gas company or the payment point to charge the gas fee. If there is no gas stop, it is recommended to install a booster pump to stabilize the pressure.

3.The water heater pipe is too long, which will lead to the instability of the water temperature of the gas water heater, and it is necessary to ask the technician to reinstall it to avoid damage to the gas water heater, and improper operation is also prone to potential safety hazards.

Gas water heatersHow high and low the water temperature? 1. It may be that the distance between the pipe outlet of the hot water pipe and the water heater is too far. 2. It is also possible that there is too much scale in the water heater, resulting in pipe blockage and unstable water temperature.

3. It is also possible that the water pressure of the tap water at home is unstable, causing the water temperature of the water heater to fluctuate. 4. It is also possible that the service life of the water heater is up, and the internal parts are aging.

Suggested Treatment:

1. If it is the plumbing process of the water heater at home, you can ask a professional orange water heater installation and maintenance personnel to come to reinstall it to shorten the pipeline distance between the water heater and the water outlet.

2. If the family likes to open the water heater above 75 degrees when using the water heater, it is easier to precipitate a large amount of scale substances, block the water heater's water outlet, and the temperature will become fluctuating.

3. Check the water pressure at home, if the water pressure is unstable, it is recommended to install a pressure stabilizing pump, which can fundamentally solve the phenomenon of unstable water temperature.

4. If the water temperature is hot and cold and seriously affects the use of the family, you can consider replacing a new water heater, which is expensive to repair for too long, and the probability of failure again is also high.

1. If you live in a high-rise building, it may be caused by unstable water pressure. 2. Under normal circumstances, there may be too much scale in the water tank and pipeline, if the hot water is hot and cold, and at the same time accompanied by a similar sound of gas and flow, it means that the scale should be cleaned. 3. The nozzle hose is aging, the pipe is expanded and twisted, and the new hose should be replaced.

1. Before using the bent skin air water heater, check whether the window or exhaust fan of the room where the water heater is installed is open and whether the ventilation is good. When in use, if the water inlet valve is opened, and it is found that the fire is not ignited and there is gas overflow, the water inlet valve should be closed immediately, and the water inlet valve should be opened again after a short stop. If the fire cannot be lit many times, it should be stopped and repaired.

2. When the water inlet valve is opened, after the water heater is ignited, the hot water can be released after 45 seconds, and then the water volume can be adjusted as needed. Metal pipes should be used for gas pipelines, not rubber pipes, so as to avoid accidents after aging. The place of use should be well ventilated, and it is best not to use the gas water heater continuously for a long time.

Attention should be paid to the smoke exhaust pipe to prevent corrosion, and the flue should not leak or be blocked.

Gas water heaters

Reasons for the high and low water temperature: 1. The water heater pipe is too long, resulting in the unstable temperature of the gas water heater; Ask the technician to swim without reinstalling. 2. The water heater has too much scale, and the pipe is blocked, resulting in the unstable temperature of the water heater, and the scale should be removed regularly.

3. If the water pressure of tap water is unstable, install a pressure stabilizing pump.

This answer is applicable to most water heater models of Shengyin brands such as Wanhe, Midea, and Haier.

Hello, I have seen your question and am sorting out the answer, please wait a while

Kiss us here to give you an analysis of the reasons for the high and low water temperature of gas water heaters: 1.
