There are two sets of heating that are not hot, and the last group of heating that is not hot

What the friend above said makes some sense. In fact, this kind of thing you are talking about is a common problem of all series pipelines. But what you said is a bit of a problem!

Heating upper half hot! Your heating is definitely not bottom-in, bottom-out, it should be up-in-and down!. If you change to the bottom in and out then !

The effect is definitely not as good as it is now! Lack of stress is a definite reason ... It is recommended that you are outside!

That is, into your home two heating pipes for water supply and backwater! What you should know ! [The hot water supply is the inlet water, and the slightly cooler return water temperature should be about 10 degrees.]

Then, go outside and loosen the pipe that controls the backwater in your home. Then turn on the water supply slowly early [don't forget to turn off the heating in the house] or you will clean it up. At this time, there must be the sound of running water in the heating at home.

After a while, the heating outside will flow out a lot of embroidery water, or even dirtier... Don't be too demanding. Because there are these things in the heat pipes, it's almost fine.

Then connect the return pipe. Generally there is no problem!. If your heating is half hot.

If there is no sound of running water. It's just that if there is a problem with the heating, it is a problem with the connection. Because the current wall-mounted heating is divided into left in and left out, right in and right out, up in and out of the wall.

Down-in, down-out, or the traditional up-in, down-out. Maybe you didn't make it clear to the seller when you bought the heater. It is also possible that the master who installed the heating is lazy. , all are possible. ，。Then there's the problem of the heating company.

The temperature of the room cannot be maintained above -10 degrees Celsius. , the specified temperature,. ,If you live at home at a high level, the pressure itself is at the bottom.。。

Is it to find your property or heating unit if it doesn't work... Buy a few packs of cigarettes. Tell them to turn off the valves of other households...

Of course, without affecting the heating of others. ，。If you're embarrassed, buy yourself a small pipe pump.

An in the backwater,,, more than 100 yuan... Domestic. ，。

Surely there is no problem ... It's about the same as the manual money spent on changing the heating. It's definitely going to be hot、。。

Now that the weather is cold, the family should pay attention to keeping warm. ，。

Your heating turns too much when you do it, and by the end of the two sets of pressures it gets low, so the temperature is not high

Connecting radiators in series will solve the problem:

One method: up-in-down + down-in up-out + up-in, down-out + down-in, up-out.

The two methods are: up in and down out + up in and down out + up in and down out + up in and down out + up in and down out.

Both of these installation methods can solve the problem, after the installation is completed, the first group may be hot and the back is not hot, and after a long time, the indoor temperature will be hot. The radiator in the front is hot, and the back is not hot temporarily, which means that the heat dissipation in the room is large. Note:

This situation is different from the heater that has a set of energy heat.

Install an automatic exhaust valve on the tallest radiator.

Because the last set of radiators installed has a clogging problem, which is also the most common situation, and the blockage can be solved by cleaning it in time.

You can turn off all the normal radiators, if the temperature of the last radiator rises, this is because of the imbalance of water circulation, when the heating system is working, if the water circulation system is not good, it will also lead to some radiators can not achieve the heating effect.

After the heating is over, it is recommended that you close the valve at home, and the pipe should be filled with water, which can effectively extend the service life of the radiator, and there will be no leakage in the second year of heating. If the temperature is not particularly ideal during the heating period, the pipes should be cleaned after the heating is finished to ensure that the water flow is smooth and the heat dissipation is normal.

Reasons why the last set of radiators are not hot:

1. You need to check whether the valve of the radiator is open, if you find that the last group is not particularly hot, you should check the heating system, whether the valves are all open.

2. If the last group is not hot, it may be that the radiator installed in the last group is blocked, which is also the most common situation, and you need to see if it is caused by blockage.

3. There is another reason to self-check, we can turn off all the normal radiators, and if the temperature of the last radiator rises, this is caused by the imbalance of water circulation, when the heating system is working, if the water circulation system is not good, it will also lead to some radiators not achieving the heating effect.

Specific solutions.

Once we have found out the specific causes, we can prescribe the right medicine and solve them one by one.

1. If it is because the radiator valve is not opened, you need to open the valve of the last group, which is rarely the case.

2. If the last group of radiators is blocked, such as the air is blocked in it and is not discharged, you need to open the exhaust valve, and then close it after exhausting the air to see if it is effective.

3. If it is caused by water imbalance, it is very simple to solve, first turn off the normal radiator and then let the last group of radiators gradually heat up, and then turn on other normal radiators, so that all the heating pipes can work normally.

If you are connecting radiators in series, it is easy to cause the temperature of the radiators to be uneven, high in the front and low in the back.

There is no pump as a circulation device for hot water, so it can only rely on the small density of hot water to rise, and the density of cold water to sink high, so as to form self-circulation. In such a pipeline system, the height of the heating end must be higher than the front, and the pipeline installation must be at a certain angle.

If the inclination of a certain group of radiators is not enough, it is easy to cause the group of radiators to not be hot.

It may be that the heating in your home is blocked, so the water circulation is not particularly good, and the back is not particularly hot.

It may be that there is a blockage inside, there is scale or rust, so the heating behind is not hot, you can go to a professional to repair it.

I think it's possible that your heating is broken, or it's too cold, which is why this is happening.

It should be that it has been used for too long, or the heating in the back is not turned on, so there is no good water-based.

The main reasons for the hot and non-hot groups of radiators are: 1. The water supply valve or return valve of the radiator is too small, resulting in too little water per unit time. Workaround:

Open the valve to the maximum (but note that if it is a three-way control valve, it should be closed, otherwise the higher the opening, the lower the temperature). 2. The connection mode is series, and the biggest feature of series connection is to save the amount of pipes and connect simply, but it is also easy to cause the front end to be hot and the back end cold. Workaround:

It is better to change to a parallel connection, or add a circulating pump to increase the circulating capacity. 3. There is a backlog of air in some radiators: after the presence of gas in the radiator, it will cause the flow of hot water to be poor, and cause the radiators in this group to not be easy to heat up and dissipate heat.

Solution: Open the exhaust valve (running air) on the radiator plug to expel the gas. 4. The resistance of the heating pipeline system is too great

Poor flow of hot water and uneven temperature dispersionSolution: Increase the circulating pump, or try to adjust the opening degree of each valve to evenly distribute the temperature of each group of radiators.

If the heating is only hot in the first group, the back room is not hotIt may be that the heating is blocked, or the heating in the back room is not exhausted in time, or it may be caused by insufficient pressure from the heating company.

I live in the Northeast, my house is using heating, if the heating is only the first set of heat, and the heating in the back room is not hot, it is likely that the heating is blocked. The water from the main pipe of the heating company is circulated to the heating of each house, and there will be a lot of impurities in the water, which will cause the heating to be blocked. If the heating is blocked, the heating in the back room will not be hot, and the solution is to uninstall the heating and dredge the blockage, and the heating in the back will be hot.

Because the first group of heating is hot, it means that the heating is normal**, so the heating in the back room is not hot, because the heating is not exhausted in time. Every year, when the heating is made, the maintenance master will tell me that it is necessary to exhaust the air in time, and there can be no gas in the heating, and if there is gas in it, the heating will not be hot. The solution is to exhaust the air in time, open the air vent valve of the heater, chase the exhaust, and after the exhaust, the heating of the rest of the house will be hot.

Our family encountered this situation, the first group of heating was hot, and the heating in the back room was not hot, I thought it was strange at the time, and suspected that the heating was blocked, and then even if the heating was dredged, it did not solve the problem. So I went to the maintenance master of the heating company, and they told me that it was caused by the lack of pressure, and they asked the higher authorities for gas that night, and then the heating in our house was hot. If you also encounter this situation, it is likely to be the same as the situation in our family, that is, the pressure of the heating company is not enough, and the solution is to call the maintenance master ** and ask them to ask the higher department for gas.

If the heating in the room is not well circulated, it will cause the first group of heaters to be hot and the rest not hot. If this happens, change the heating again or install a booster pump on the heating.

Introduction: If the first set of heaters appears, and the rest is not hot, it is necessary to see if it is broken. <>

1. What is the situation?

Many people will choose to use heating in winter, if the heating is the first to resist the heat, the back is not hot, to repair in time. Some people will keep the heating on when they use the heater, and they want to see if there is too much gas stored in the radiator, resulting in a situation that is not hot, so they should open the contents and then repair it. If you find that there is no heating phenomenon and do not repair, it will also lead to some situations must be adjusted appropriately, if you find a problem with the system, then at this time you should also look at whether the power of the heating is high, if the power of the heating is not high, there is no way to carry out comprehensive heating.

2. How to repair?

If you usually see a lot of these radiators, then you should also repair them appropriately, and make appropriate adjustments in the process of maintenance. Many people will have a variety of problems in the process of maintenance, at this time we must see if the radiator is too long to need to be replaced, if it needs to be replaced, then it is necessary to replace it in time, do not be careless, and do not be afraid. When choosing a heater, be sure to choose some good heating for use.

3. Summary. Some people will choose to use the heating in winter, if you find that the heating problem should be adjusted in time, if the radiator is not hot, you must repair it in time. Many people will feel very cold in winter, if there is no heating, it will feel cold in the whole house, and it must be adjusted appropriately at this time. If you usually feel very cold, you must wear more thick clothes at this time, so that you will not be cold.

If you feel very cold, you can also turn on the heater appropriately.

This is a common problem of tandem radiators, because each group of radiators is connected in series, and the hot water needs to pass through each group of radiators in turn, and each group of radiators will lose a part of the heat, so the more radiators go to the back, the worse the effect.

This is because the hot water in the heating pipe is not well circulated, and a circulation pump can be installed on the heating pipe to circulate the hot water in the heating, so that the cooling and heating in the heating are uniform.

Because a lot of heat is left in the first group during the first group, the temperature of the subsequent groups will gradually decrease.

1. The parallel heating group is not hot.

It may be caused by the different heights of the radiators, the heating is connected in series, you can not consider the height of the radiators, as long as the high and low positions of the two ends of the single group of heating are found well, it may be that the flow of the valve is too small, and there will be a control valve in the home, if the heating is not hot, it is likely that the valve is too small to cause the flow to be too small.

Second, how to solve the problem that the side-by-side heating is not hot.

1. The heating needs to be replaced for "overdue service".

Residents should replace their heating with new ones before they reach the maximum age limit.

2. The heating needs to be deflated if it is "breath-holding".

At the back of each radiator is a manual air release valve that unscrews the rotating shaft to drain the air until the flow is smooth. If the screws of the heating air vent valve have rusted to death, do not twist it rashly, so as not to break the air vent valve and cause the heating hot water to spray out, and ask professional plumbing personnel to come to repair. At the same time, residents living in high-rise buildings should regularly check the heat of the heating, and if there is any uneven heat, they should exhaust the air in time.

3. The pipeline system is blocked and needs to be cleaned.

Normally, geothermal users should clean their pipes every two years, and older heating users should have their pipes professionally cleaned every seven to eight years.

In the case you mentioned, two sets of radiators are connected in parallel, one is hot and the other is not. It means that there is gas in the radiator that is not hot, or there is a blockage at the elbow. It needs to be overhauled.
