Why does the water heater get hot all at once, and what is the reason why the water heater is cold f

The resistance of the water heater is large, and the voltage is divided, and the work is more, and the heat is very fast, so it will heat up all at once.

I don't know if your water is hot all at once, or if the water heater itself is hot all at once, it's a different concept.

A big fire burns a small amount of water, and you say it won't heat up quickly.

Just ask the manufacturer.

The heating equipment is broken and the heat is abnormal.

Simple, you stupid, you don't know any common sense.

1. If the water heater is at a constant temperature, it may be that there is a problem with the heating electronic components, or there is a problem with the power, which causes the water to be hot and cold. 2. It may be that the water flow itself fluctuates from one to the other, causing the water of the water heater to be cold and hot for a while. 3. It may be that the voltage is unstable, or there is a problem with the mixing valve, which causes the water to be hot and cold.

Recommended Actions:

1. You can turn on the faucet at home to see if the water flow itself is big and small, if the water pressure is unstable, it may cause the water of the water heater to be cold for a while and hot for a while. At this time, it is necessary to find a way to stabilize the water pressure in the home.

2. You can carry out preliminary troubleshooting of the water heater according to the manual, if the fault cannot be eliminated, then it may be a problem caused by the internal electronic components, and you need to ask professional after-sales personnel to come to the door for maintenance.

3. The internal deposition of the water heater may cause the failure of electronic components, and the inside can be cleaned with a professional descaler, which can also ensure the cleanliness of the water quality.

4. After the water heater reaches the service life, it is recommended to scrap the water heater in time, the requirements for safety performance are still relatively high, and it is easy to leave potential safety hazards if it continues to be used after reaching the end of life.

There is usually only one situation when the water heater water temperature becomes super hot, that is, after you use it for one to two minutes, turn off the water, and then turn on the water again for half a minute to one minute, and the super-hot water from the water heater will be used until the water temperature is normal, about 5 seconds.

The maintenance of electric water heaters is very important, on the one hand, to ensure the safety of electricity, and on the other hand, to see whether it can achieve the expected service life.

1. Clean the inner tank regularly, because of the trace impurities and minerals contained in the water, after long-term use, it will slowly precipitate, if it is not cleaned, it will affect the water quality and the service life of the whole machine;

2. The user of the electric water heater regularly asks professionals to inspect the equipment every year to check the safety performance and eliminate potential hidden dangers;

3. If it is idle for a long time, turn off the power supply and drain the water storage of the inner tank;

4. In order to ensure the normal use of the water heater, the safety valve needs to be maintained no less than once a month to ensure the normal pressure relief of the safety valve.

1. It may be a power supply problem. Since the power is turned off, the water heater is in a state of insulation, and the temperature of the water slowly decreases after using the hot water for a while. 2. It may be a problem of water pressure, the unstable water pressure makes the water output fluctuate, resulting in an increase in energy consumption of the water heater and insufficient heating capacity.

3. It may be caused by the internal constant temperature problem of the water heater. Suggested solutions: 1. Check whether there is a power outage, leakage, and whether there is a problem with the plug board.

If there is a power failure, you need to check whether the plug is tightly connected; In the process of use, the leakage will protect the plug to self-power off, resulting in automatic tripping or elephant, you need to press the reset button to restore the power supply; If the plug-in board is short-circuited or the chip inside burns out, it needs to be replaced with a new one. All of the above methods need to be powered off. 2. Install a booster pump on the cold water pipe that enters the water heater.

In this way, even if the tap water pressure is insufficient, it can ensure that there is no problem with the outlet pressure of the water heater. 3. Check the fault displayed by the water heater**, and then deal with it according to different fault causes. The problem of the tung degree of the thermal group of the water heater generally shows E1, that is, the plug-in of the sensor is worn out, and the connector needs to be plugged in again.

Or replace the connector with poor contact. If the sensor is damaged, the temperature sensor needs to be replaced.

If the main controller board fails, replace the main control board.

It could be the thermostat inside the water heater.

This will happen to the water heater if it is damaged and does not start properly. If the water heater heating rod is damaged, it can also cause this problem. It is also very likely that the power supply connected to the water heater is not in good contact, and in the case of abnormal power supply, it is easy to cause the water heater to not heat up for a while.

Suggested solutions: 1. First check whether the power supply connected to the water heater is normal, if there is a problem of poor plug contact, you need to unplug the power supply in time and then plug it back in, and then restart the water heater This problem can be solved. 2. Due to long-term use, the heating rod inside the water heater may be damaged due to too much scale or too long, in this case, it is necessary to contact professional maintenance personnel in time to replace the heating rod inside the water heater to solve the problem of not heating for a while.

3. If the thermostat inside the water heater has been damaged, it will cause the water heater to continue to heat and the water temperature will rise, causing the switch to jump open after the high temperature limit, and the water heater will disconnect the power supply.

Dear, hello, I am happy to answer for you: The reasons why the water heater is cold for a while and hot for a while are as follows: 1. The water pressure is not enough When it comes to bathing in winter, many people are used to turning on the hot water switch to the maximum, but once the water feels hot, someone will adjust the faucet violently, and the newly added cold water will increase the resistance of the water out, and when the resistance is large enough, it will cause the gas water heater to go out.

There will be hot and cold situations. Solution: In this situation where the water pressure is not enough, one way is to add a booster pump, if you don't want to install it, you can choose to use the water heater when each person uses water.

If the water is supplied by the water tank on the roof, the pressure is only related to the height difference between your home and the water tank, and the water pressure is not enough, you can consider installing a water pump. The second method is to find the property to solve the water pressure problem, causing the water heater water temperature to not be hot enough or hot for a while and cold for a while, if the water volume of the shower is not significantly reduced, it may not be a problem of water pressure; It can solve the problem of hot and cold gas water heaters. 2. The location of the water heater If the water outlet of the gas water heater is far away from the water heater, such as it is installed on the balcony, it is necessary to confirm whether the cold water of the water heater is turned on to the maximum?

This is very important, because the tap water is not turned on to the maximum, and the water heater will be turned off due to insufficient flow and high temperature when the water temperature is adjusted at the outlet. 3. If the water heater of the user using bottled liquefied petroleum gas is hot and cold, you can check whether the pressure reducing valve is normal. 4. Adjust the water volume adjustment button of the water heater You can adjust the water volume adjustment button of the water heater to the minimum.

If it hasn't been hot or cold before, you can check to see if the water inlet of the water heater is blocked. 5. The water outlet of the gas water heater is not hot The outlet water is not hot This is caused by the water flow is too large and the capacity of the gas water heater is too small. Nowadays, the capacity of gas water heaters mainly includes 8 liters, 10 liters, 11 liters and other specifications, and if a family of three usually only needs to shower, it is enough to buy a 10-liter gas water heater; However, if you need to take a surf bath or a bathtub, it is best to choose more than 10 liters.

It is worth mentioning that when taking a bath at night at zero degrees Celsius, it is best to empty the remaining hot water in the water heater after washing, so as not to freeze the water heater and damage the water heater. 6. Whether the water heater has been used for too long The scrapping life of gas water heaters is 6 years, and the scrapping life of liquefied petroleum gas and natural gas water heaters is 8 years. Users should "trade in the old for the new" in time to prevent potential safety hazards.

If the water heater has been used for a long time and needs to buy a new machine, it is recommended to choose a thermostatic water heater, which can be accurately judged in an instantaneous manner according to the real-time water consumption of the gas heater and the change of the inlet and outlet water temperature, and command the combustion system to burn in sections with a fully optimized state, and at the same time command the unique stepless fan to reasonably allocate the combustion air required to achieve super energy saving and keep the water temperature constant. In this way, there will be no more hot and cold baths.

First, the water pressure is unstable due to the height of the water heater.

Solution: If it's a water pressure problem, then we can solve it as long as it doesn't conflict with peak water use.

Second: the mixing valve is not very suitable for commissioning, which causes the water in the water heater to be cold when the heat treatment method: how is the mixing valve problem, it is recommended that you install a thermostatic valve on the water heater at home, so that you can ensure the normal use of the water temperature, and not when it is cold and hot.

Third: The water heater has not been cleaned for a long time, check whether the water inlet of the water heater is blocked.

Solution: Clean the water heater in time and replace the magnesium rod if necessary to avoid limescale blockage.

The above is an expert for the water heater to release a cold and hot water causes and solutions to introduce, through the maintenance experts' answers, whether we have a certain understanding, and finally the maintenance experts suggest that when there is a similar failure, it is best to find a professional for maintenance.

Water heater, this is available in everyone's home, and many people are no strangers, so what are the reasons and solutions for this gas water heater to be cold and hot?What is the reason why the lights are on and not heated:

Gas water heater will be cold and hot for a while Causes and solutions:

1. Reasons. Before analyzing the reasons why the gas water heater is hot and cold, let us understand the national test requirements for water heaters, especially about the flow rate and temperature, so that it is easy for everyone to understand, according to the national standard GB6932 standard, if the indicated flow rate of the water heater is liters, this explanation is like this, that is, when the combustion power remains unchanged (such as 40kw), according to the inlet water pressure required by the national test, the water heater outlet water reaches liters minutes, The temperature of the effluent can be 25 degrees higher than the temperature of the incoming water, which is why we can see the temperature rise of 25 degrees (δt = 25 degrees) on the technical specifications of the product.

Often the water pressure in the laboratory can be kept constant, but the actual water pressure used at home has been changing dynamically, and the water pressure in different parts of the country is not the same, in the same area, because the user consumes different water at the same time, the water pressure will be different, so that due to the instability of the inlet water pressure, the water temperature changes when consumers use the water heater, resulting in the fluctuation of the water use, and the water temperature is high and low.

2. Solution.

Retrofit flow regulation.

We can ask water heater manufacturers to install a flow regulator device at the water inlet site, we also call it a flow regulator, considering that more than 85% of China's areas are low water pressure, that is, the water pressure will not exceed, then the flow regulator needs to choose a product that can start and work at low pressure. For example, if the flow rate indicated by the flow regulator is 10 liters, then the flow regulator will always supply water for 10 liters in the pressure range, and the temperature of the water will be maintained at a certain level under the condition that the power has been set, and the comfort of bathing will be greatly improved, and the cost of the flow regulator is not expensive.

The main reason is that the flow rate and temperature of the water heater are insufficient. Treatment: Turn the gas water heater to a high flow rate and raise the fire. The cold water pressure is not enough or the pressure is unstable, causing the water in the gas water heater to be hot and cold for a while, which is the root cause.

The instantaneous gas water heater is like an upgraded version of the instantaneous electric water heater, which not only solves the problem of ordinary instantaneous electric water heater generally having little water in the harsh winter, but also solves the problem of slow hot water output and safety of the gas water heater

If it's broken, or some parts are not in good contact or damaged, contact the manufacturer's customer service.

The reasons and handling are as follows:

1. The main reason: the flow rate and temperature of the water heater are not enough.

2. Treatment: Adjust the gas water heater to a large flow rate and a large fire. The cold water pressure is not enough or the pressure is unstable, causing the water in the gas water heater to be hot and cold for a while, which is the root cause.

3. If it is not a thermostatic water heater, then aim the temperature button in summer.

4. If it is an old-fashioned machine, first adjust the shower valve to the left, then adjust the water temperature of the water heater to the maximum, adjust the air to the minimum, and turn on the machine to test the water temperature. If the ignition does not catch fire, you can increase the water temperature slightly. After ignition, adjust the air to about 40 degrees, and when taking a bath, you can appropriately adjust the cold water to the point where it is applicable.

Extended information: A water heater refers to a device that turns the temperature of cold water into hot water within 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.
