What s wrong with the newly installed water heater not producing hot water

The most common reasons why a household water heater ignition does not light up:

1. Low water pressure; 2. Poor line contact (including poor contact of water level switch, poor contact of transfer switch in winter and summer, poor contact of battery box, poor contact of lead wire connected to the ignition); 3. The water inlet pipe and outlet pipe are blocked, which will also make the water heater appear low water pressure (the household water heater that has been used for many years is usually blocked, and the solution is the backflush method, that is, the hot water (shower unscrewed) is connected to the cold water inlet switch, and the water inlet pipe is used as the outlet pipe, and the switch is repeatedly turned on several times, and then connected back to the normal position, which can solve the problem of low water pressure); 4. Low battery energy and poor solenoid valve.

According to the information you provided, the low water pressure and clogged pipes are the most common causes, please check.

The reason why the water heater does not produce hot water.

Water heater is a household appliance often used in home life, and it is also an indispensable household appliance in a modern family, but there are often problems when the water heater is used for a long time, such as the situation that the water heater does not produce hot water from time to time, so what is the reason why the water heater does not produce hot water?

Cause 1: The water pressure of tap water is high.

In fact, problems with water heaters used in family life are generally due to people's inattention in daily use. In addition to maintenance, appliances such as water heaters also need to pay attention to their hygienic environment and temperature changes in the area. As the frequency of our daily use of water heaters gradually increases, it is likely that the tap water pressure will be too high, and the tap water pressure will not produce hot water from the water heater.

Cause 2 Vacuum tube failure.

The situation of vacuum tube destruction generally occurs in solar water heaters, which reach the boiling point in less than two days on a hot sunny day in summer. If it is not used for a long time, the hot water tank will be in a state of high temperature and high pressure for a long time. In this state, the sealing ring in the tank deteriorates rapidly, which will accelerate the aging and shrinkage of polyurethane.

Sometimes the drainage of the water tank is not smooth and the pressure is too large, which will also make the water tank swell, and it will also form scale, which shortens the service life of the water tank and will also cause problems in the water heater from time to time.

Solution 1: For the problem that the water heater does not produce hot water, we need to solve it according to different situations. Sometimes the water heater does not produce hot water just because the thermostat trips, and generally the water heater will have two temperature control modes: room temperature control and over-temperature temperature control. Therefore, when the water heater does not produce hot water, we can check whether the temperature control switch of the water heater is in the wrong position.

If this is the case, we can change it to room temperature control mode.

Solution 2In addition, if the water pipe connected to the water heater is clogged, or the water is in a state of water outage. Since the working principle of the water heater is that in the presence of water, the cold water supports the direction of the hot water, and the water heater in the state of water outage is unusable. So, we can check to see if the water inlet of the water heater is blocked, or if the water flow is not entering the water heater at all.

If this happens, we need to find a professional maintenance person to see if there is a problem with the water pipe.

Solution 3: If you feel that the water heater is always having problems, it is recommended to buy a water heater with zero waiting for water to come out. Rumei's full-type HT3 gas water heater. The 5800 rpm turbocharged water pump makes the water flow in the hot water pipe smoother, and there is no need to wait for hot water.

Before solving the problem, you should understand the reason why the water heater does not produce hot water, and only by knowing the cause can you solve the symptoms. First of all, check whether the power connection of the water heater is intact and whether there is any loose plug.

First of all, the water heater of the thermostat trips caused by the hot water, generally the water heater will have two temperature control methods: over-temperature temperature control and constant temperature temperature control, if the water heater does not produce hot water, you can first check whether the position of the thermostatic switch of the water heater is misplaced, some water heaters even adjust the temperature to the lowest or not adjusted at all, in this case, it is impossible to produce hot water!

Check whether the water heater can be ignited normally, if the ignition machine uses a battery, first check whether the battery is not charged, check whether the micro switch lever can be fully opened when the power is turned on, if it can't be opened, the diaphragm is aging or damaged, and it is good to replace it in time. If the ignition can be turned on and the micro switch lever can be fully opened, it means that the ignition is normal, and it is possible that the fire power is reduced and the hot water cannot come out, and it is speculated that it may be caused by the blockage of the fire row.

Then check the pressure relief valve of the water heater, when the pressure relief valve of the water heater increases, once the internal pressure exceeds the safety pressure value, it will drip water from the safety hole to the outside to reduce the pressure, and prevent the cold water from heating and expanding back to the water pipe, so once there is a problem with this pressure relief valve, it will also cause the water heater to produce hot water.

There is also too much scale inside the water heater, which is not cleaned regularly, resulting in scale blocking the inside of the water heater and causing the water heater to not come out of the hot water, which requires regular cleaning of the water heater.

There is also a situation that the hot water can not come out caused by the destruction of the vacuum pipe, which generally appears in the solar water heater, the temperature in the hot water pipe at high temperature is relatively high, if it is not used for a long time, it will easily cause the aging of the sealing ring in the water tank, cause the drainage of the water tank to be poor, and it is also easier to cause scale and cause problems in the water heater. In the summer, when the temperature is too high, the water in the water heater is discharged when not in use, and if the vacuum pipe is damaged, it still needs to be repaired by professionals.

Finally, I want to say that the water heater should be cleaned regularly, once there is a problem, if the check is not a loose plug and the thermostat tripping caused by the visible small problems, you should ask a special maintenance personnel to repair it, it is not recommended to open the water heater casually to check and repair.

There are many reasons why the water heater does not produce hot water, and if the gas is insufficient, a gas pipe can be replaced; If the ignition device fails, the relevant accessories can be replaced; The flow of water is too high.

The water output can be reduced, or the inlet water can be turned off; If the pipeline is too long, it can be insulated; If there is too much carbon deposited in the heat exchange, the panel can be opened, and the inside can be inspected and cleaned;

If there is too much cold water, the temperature should be adjusted according to your own water habits; Find a professional to repair it.

Check the pipes of your water heater for any blockages. Generally, the hot air will not come out of the water, and check whether the pressure valve of the water heater is not good, and replace the pressure valve.

If you don't have professional technology, you must not do it yourself, but find a professional maintenance master to solve it. Because not only can you not fix it, but there will be some potential dangers.

First, when the gas is insufficient, there is no hot water, we must first check whether the machine has no gas. If there is no heat energy**, there will be no hot water coming out of the heat. In addition, it is also possible that the gas channel is blocked, causing the amount of hot water to become smaller, resulting in less fire power and slower boiling.

Solution: Replace a gas pipe.

2. If the ignition device fails, the water heater does not produce hot water, and it may be that the ignition device is faulty. In this case, we first check whether the power is sufficient, and then observe whether the pressure sensitivity of the micro switch can be fully turned on every time the machine is started. If not, it may be that the diaphragm inside is aged or broken.

3. When the water flow is too large and the water temperature difference between the hot water and the inlet water is greater than 25, the hot water flowing out per minute will not reach the number of liters of hot water that is calibrated. At this time, the hot water flow of the water heater will become smaller, or even not out. Solution:

Reduce the amount of water outflow, or turn off the inlet water.

Fourth, the pipeline is too long, the gas water heater does not produce hot water, it may be that the pipe is too long, and the water pipe is not insulated. In this case, when the temperature is low, there is no way to ensure that the hot water will still be high when the water is delivered to the terminal. Treatment: Do thermal insulation treatment.

5. Too much carbon deposition in heat exchangeThe heat exchange of water heater is an important component of converting heat energy into hot water, and the gap between its productions is small. When the machine burns, it is very easy to have carbon deposits, which greatly reduces the power of the hot water of the water heater. Solution:

Open the panel and inspect and clean the inside. If there is too much carbon accumulation in it, remove it and clean it, usually once a year.

6. Add too much cold waterMany people like to turn up the heat in the bath, or adjust it to high temperature, and then add cold water to ensure that the hot water is sufficient and the washing is smooth. As a result, the hot water in the machine will be squeezed by the cold water, causing the gas water heater to turn off. Solution:

Adjust the temperature according to your own water habits.

The common reasons why a water heater does not produce hot water are as follows:

First, the water heater adjustment setting is not good

If the water heater does not produce hot water, you can check the setting of the water heater first, this situation is more, many users in the use of electric water heaters in the temperature adjustment to the minimum, or no adjustment, so that there will be no hot water at all. Therefore, you need to adjust the setting before using it and set it at the appropriate temperature.

Second, there is a problem with the thermostat

Whether the power supply of the electric water heater is bright, if not, it may be that there is a problem with the thermostat, generally the better electric water heater has dual thermostats, that is, room temperature control and over-temperature temperature control.

These two kinds of temperature control are used to control the display and control of the water temperature of your water heater, and the other is to avoid tripping when there is a problem with the temperature control at room temperature. That is, double insurance, some of them will directly lead to the inability to boil hot water because of temperature control tripping. Calling a professional to turn on the machine quickly got it done.

3. The hot water pipe is blocked

The water heater can't get hot water, it may also be whether the hot water pipe is blocked or the water is stopped, and the water stop will directly cause the water heater to be unusable, because the principle of the electric water heater is that the cold water runs against the hot water, and see if the water inlet of the water heater is blocked. In this case, you only need to unblock the blocked hot water pipe and let the hot water flow out fully, and you will be fine.

It has two self-operated stores on JD.com and Tmall and a number of franchise stores, and in the process of development, it continues to provide consumers with excellent and high-quality life with forward-looking technology and considerate service, and is committed to becoming the most influential and competitive leading brand of kitchen and bathroom in China.

Reasons why the storage type electric water heater does not produce hot water:

First, the water pressure is too low or the water is stopped. Low water pressure is a common problem in high-rise buildings now, and it is difficult to solve it, so when choosing a house, try to choose a community built by a powerful developer. In the case of water outage, the inside of the electric water heater can be heated, but because the inside is closed, if the tap water is stopped without pressure or the pressure is very low, then the hot water will not be pushed out, resulting in no hot water.

Second, the temperature limiter tripped. There are two temperature controllers inside the electric water heater, one is a thermostat, which can adjust the temperature of the heated water; There is also a temperature limiter, which can avoid the temperature rise, and can automatically trip after the temperature reaches the limit temperature in time.

Answer pro, in this case, check whether the switch of the hot water valve is turned on; Check whether the hot water valve is faulty and replace the hot water valve; Remove limescale from the sprinkler; Check if there is a problem with the mixing valve and ask a professional to repair it. Here's how to solve the problem:

1. Check whether the switch of the hot water valve is open.

It is not uncommon for the hot water valve to not turn on or to be forgotten after the last time it was turned off.

2. Check whether the hot water valve is faultyThe hot water valve is faulty, which will naturally affect the hot water, if it is really caused by the failure of the hot water valve, it is best to replace the hot water valve.

3. Check whether the sprinkler head is blocked.

If the water quality is not very good, and there is no regular maintenance and cleaning, it is inevitable that there is some dirt inside that blocks the sprinkler head, and the scale can be removed.

4. Check if there is a problem with the mixing valve.

If there is a problem with the mixing valve, it may also lead to no hot water, and you need to find a professional to overhaul it.

Question: Which switch is the hot water valve?

If there is still no hot water coming out after opening, it is estimated that the set water temperature is not enough to continue heating, and the control valve is closed.

What is the reason why the electric water heater cannot release hot water?

How to solve the problem that the water heater does not produce hot water.

The switch of the hot water valve is not open.

The hot water valve switch is not turned on may be our carelessness, or after the last time it was turned off, we forgot about it, and this situation often occurs.

2.The amount of water supplied to the inlet

The water heater can not release hot water may also be due to the amount of water supplied by the inlet water, in fact, this is relatively easy to understand, because there is no water supply at the water inlet, not to mention hot water, cold water is not available, so this situation must be avoided, and sometimes it will also lead to the water heater tripping or more serious.

3.Water heater safety valve issues

If it is the water heater itself, it may be that there is a problem with the safety valve of the water heater, when the internal pressure of the water heater rises, when the safety pressure is exceeded, it will drip water from the safety hole to relieve the pressure, and also prevent the cold water from expanding and flowing back into the water pipe after heating. If there is a problem with this valve, it may also cause water to not be able to enter the water inlet, so it will cause the water heater to not produce hot water. The safety valve of some water heaters needs to be checked, and if it is found to be a safety valve problem, it can be replaced with a new one.

4.The inside of the water heater is blocked

The inside of the water heater is clogged, and there is a lot of dirt in it, so I usually don't pay attention to cleaning. If the filter screen at the outlet of the water heater is blocked, it is necessary to pay attention to cleaning and maintenance, remove the water heater, and clean the filter. 1. The heating time becomes longer, the water is cold and hot, and the water output per unit time is reduced.

Follow the above steps to check, it is normal to find out the reason why the water heater can't release hot water, I hope to help friends with similar problems!
