Why does the radiator stop heating after a while?

Reasons why radiators don't get hot after being used for a long time:

1. Pipeline blockage:

Mainly because of the poor quality of the radiator, the inferior quality of the radiator inside.

The anti-corrosion layer will fall off the slag for a long time, and then block the access.

The water inlet will cause the water to flow poorly, and the water temperature will drop.

Radiators generally have an anti-corrosion layer, if there is no anti-corrosion layer on the inner wall of the radiator you buy, or the quality of the anti-corrosion layer is not good, the pipe wall is easy to rust and fall off. The slag will move in the direction of the water flow and then slowly clog the pipe mouth of the radiator. If the pipe opening is smaller, it is more likely to clog.

2. There is too much gas accumulated in the radiator:

The heating of the radiator is achieved by dissipating the heat from the hot water inside, but if there is too much gas in it, the water cannot flow through, which will lead to the problem that the radiator part is not hot.

At this time, just open the air release valve of the radiator and exhaust the gas in the radiator. (When exhausting or daily use, too much hot water will affect the overall heating effect of the radiator.) ）

The reason why the radiator is not hot after a period of time should be because the circulation is not good, there is air in it, it is recommended to open the exhaust valve of the radiator to release the air inside.

This situation is normal, because if you use the radiator for a long time, there will be rust or scale at the bottom of the radiator, and it must be cleaned up at this time, it will be hot, otherwise, the water circulation will be poor.

Radiators at home.

In the first few years after installation, the heat dissipation effect was really powerful, and the temperature at home was very comfortable, but after a few years, the radiator heat dissipation effect was far less than before. This has a certain relationship with the daily use and maintenance of radiators. A well-maintained radiator not only does not dissipate heat, but also prolongs the service life of the radiator.

Today, Jinjin will share with you the maintenance method of radiators, so that your radiators are as warm as other people's homes.

Many friends have installed radiators when decorating, and although they have been used for seven or eight years, the effect of the radiators is still great. However, a few families rejoiced and some were sad. Some users ask Jinjin for help in the years when the radiator at home has just been installed, the heat dissipation effect is really powerful, and the temperature at home is also very comfortable, but after a few years, the radiator heat dissipation effect is far less than before.

In fact, this is all related to the daily use and maintenance of radiators. A well-maintained radiator not only does not dissipate heat, but also prolongs the service life of the radiator. Today, Jinjin will share with you the maintenance method of radiators, so that your radiators are as warm as other people's homes.

Other people's radiators have been used for so many years, why is the heat dissipation still so good?

1. The radiator should be "two clean", and the cleaning should not be excessive.

The heating season in the north lasts for about 4 months, and the radiator is easy to deposit a lot of dust and impurities during use. These particles adhere to the radiator, which will cause the radiator to dissipate heat in the long run, and the user needs to wipe it with a towel regularly. Here, Jinjin needs to remind everyone that some organic solvents must not be used when cleaning radiators, otherwise the paint surface of the radiators will be damaged.

In addition to the cleaning of the radiator surface, the filter screen of the radiator is also necessary to be cleaned, especially in areas with poor water quality. This situation is also a common reason why many home radiators do not dissipate heat well. Therefore, Jin Jin reminds everyone to clean the filter in time.

2. Do a good job of radiator drainage to prevent freezing and cracking.

If the temperature drops suddenly, if the radiator in your home is not used or no one uses it for a long time, you must drain the water from the radiator. Otherwise, once the indoor temperature is too low, the water in the radiator will condense into ice, and the density of the ice is large, and the radiator cannot bear it, and it is easy to cause the radiator to burst the accident.

3. Do a good job of water storage and maintenance during the heating period.

Everyone knows that steel radiators need to be fully watered for maintenance. But in fact, few people know that the heating period is over, and radiators of other materials need to be stored and maintained. The biggest benefit of water storage maintenance is to prevent the radiator from oxidizing.

The radiators in some homes are not warm enough, and part of the reason is that the internal oxidation of the radiators, impurities in the water flow, and poor heat dissipation are caused.

The heat dissipation effect of the radiator is not only related to maintenance, but also the installation and material of the radiator.

If the radiator is not hot for a period of time, it may be that the boiler is not burning well or there is a problem with the pipeline, if it is not hot after one year, the second year is found to be not hot, there is a new possibility that there are more debris in the radiator, the gossip road is blocked and needs to be dredged, and it can be used in the future.

Why does the radiator last for a while, for example, it won't be hot for a few years, I think it's because the water quality is too dirty and the internal rust of the radiator causes blockage.

If the service life is too long, it is necessary to consider whether the radiator is clogged and does not heat it.

Check the pipes for water leaks.

Ask about the heating company's heating.

Why does the radiator stop heating after a while? After the radiator is used for a period of time, there is limescale or other rooms in it, which needs to be cleaned, and if it is not cleaned, it will not be hot.

The air in the radiator is not released, blocking the flow of water and preventing the radiator from dissipating. It can be deflated by the exhaust valve (a small button-shaped valve at the top of the radiator) or by running the air.

There is gas in the radiator, or there are impurities blocked, and the radiator needs to be vented or cleaned. If there is a special cleaning radiator, you can find a master to clean it up. It's also possible that the heating station isn't as hot anymore, so you don't feel like the radiators are as hot as they used to be.

In addition, there may be people around who have installed circulating pumps, which affects the heating of your home, which needs to be investigated by the heating company.

The radiator has not been hot for a few years, it may be that the radiator and the heating pipe have precipitated a lot of dirt, and the dirt makes the radiator turn off and hit it, the effect is not good, and the pipe and radiator should be cleaned at this time.

Isn't it time for your radiators to be cleaned?

Sometimes there will be a lot of dirt deposited inside the radiator, and it will also affect the heat dissipation of the radiator.

If you need to clean the sludge inside, you can remove the radiator and clean it carefully.

Those few pieces are used. 3 5 years without the previous heat, give timely cleaning. Water show.

The radiator has only one piece of hot reason:

1. It may be because the direction of the water flow for the return water is connected incorrectly, and the return water of the first radiator is directly connected to the main return pipe, then the water flow direction for the return water should be reconnected according to the correct method.

2. It is also possible that there are too many turns in the water supply pipeline line, and there is gas accumulation at the bend, which causes the water supply and return to be unable to circulate normally and deteriorate.

3. It is also possible that there is air in the heating system behind it, which causes the radiator to circulate poorly, so the radiator should be deflated.

4. It may also be because when the radiator is installed, a lot of impurities are accidentally left in the radiator, resulting in the radiator system being blocked and the circulation is not smooth, so the radiator should be cleaned and dredged.

Precautions for purchasing radiators:

1. Look at the size.

There are a variety of specifications and models of radiators on the market, different specifications and models, their size, **, suitable installation location will be different, when we buy radiators, we must choose according to the actual area size of the radiator installed at home and their own needs and economic capacity.

2. Look at the brand.

There are many brands of radiators on the market, different brands, their first, production technology, production equipment, shelf life, product quality, after-sales service and other aspects will be different, we are in the purchase, it is best to choose products produced by big brands and good reputation brands, so that product quality and after-sales service will be more guaranteed.

In all heating systems, there are many advantages of radiators, and if you use them for too long, they will cause the radiators to leak.

Advantages of radiators:

Advantage 1: More comfortable.

The radiator heating method is relatively soothing, and the air in the whole room makes people feel more comfortable.

Advantage 2: There is leakage in the pipeline, and the scope of influence is small.

If there is a leak in the radiator, it is generally at the joint of the radiator pipe, which is relatively easy to see, and measures can be taken in time.

Advantage 3: Easy to transform.

When renovating and renovating the heating, the radiator is more convenient. Only the radiators and heating pipes need to be installed.

Advantage 4: The home improvement process is not affected.

In the early stage of decoration, as long as the radiator pipe is reserved, and after the decoration is completed, the radiator is hung on the wall, and the entire heating system is completed.

Advantage 5: Easy to repair and replace.

Almost all the connections of the radiator are exposed, so it is very convenient to maintain, and the cleaning of the radiator is also very convenient. Even if it needs to be replaced, the radiator can be replaced directly, without other cumbersome processes.

So is it OK for us to use expired radiators? What is the impact on heating?

1. The radiator is not hot: if the radiator is used for a long time, its inner wall will be adsorbed by the scale and impurities in the heating water, resulting in thickening of the pipe wall, smaller inner diameter, and serious blockage, which will affect the heating temperature; Therefore, it will cause no heat;

2. Radiator leakage: In the heating process, we will cause certain corrosion to the radiator, no matter what material the radiator will be corroded, but the speed is different, so the radiator is used for too long, and the pipe wall is corroded very thinly, which is easy to cause water leakage and cause us greater economic losses;

3. Ugly appearance: the radiator surface heating electrostatic powder spraying technology looks like ceramics from the appearance, which is very good-looking, but the luster on the surface will be gone after too long, and there will be a lot of scratches, which will naturally affect the appearance; At the same time, it will inevitably cause bumps in life, so that the surface of the patent leather will fall off in a large area, so it will be very ugly, affecting our home decoration style.

If the radiator is used for a long time, it will clog inside. If the radiator is clogged, the thermal efficiency will be significantly reduced.

If the radiator is used for a long time, there will be impurities and scale in it, resulting in a decrease in thermal efficiency, and it will generally be cleaned or treated with water every year.

The radiator will form scale inside after a long time, and the more scale accumulates, it will affect the flow of water and flow rate, which will affect the heat of the radiator.

I don't think the radiator will affect its heat dissipation after a long time, in fact, if it is not hot, it can only mean that the water in it is not hot enough.

The radiator will slowly become weak after a long time, but as long as we pay attention to maintenance and frequent cleaning of the radiator, the inside can ensure its use effect.

If the radiator is used for a long time, the inside will be clogged, and the thermal efficiency of the clogged radiator will be reduced. Therefore, it is usually necessary to clean the radiator to prolong its life.

No, the radiator in normal use will not be hot due to long use, as long as the radiator is not clogged, it will not cause it to be unheated.

The radiator will not be hot after a long time, this is because the water circulating in the radiator contains impurities, which are not as good as precipitating at the bottom of the radiator on the inner wall of the radiator, which constantly affects the heat dissipation of the radiator, and will also affect the circulation of hot water, which will cause water flow blockage in serious cases.

This results in the radiator being half hot and half not.

The solution is to flush the pipes and radiators to improve thermal circulation.

The phenomenon that the first few pieces of the radiator are hot and the last few pieces are not hot may be caused by the local "air blockage" of the radiator.

Solution: You can loosen a few wires of the air release needle at the upper end of one side of the radiator, stop the operation when you hear the sound of gas release, and then tighten the air release needle after the water flows out. Generally, it needs to be repeated several times before the heater will heat up.

If the radiator is not hot after exhausting, the professional staff of the heating company should be asked to find out the reason, and the gas release device should not be used to blindly drain the water.

According to your simple description, it is preliminarily determined that it is a single-pipe series installation method, it is best to add a road through the water in the middle of each group of radiators and backwater, one is to adjust the flow, and the next group of radiators is to compensate for the temperature, if you use a 1-inch pipe to the radiator, then the water must be used in a small pipe that is 6 points. With the above changes, the effect will definitely be better than before. The main reason for this problem is that in the tandem pipeline, the inlet and return water temperature of each group is gradually decreasing, and the last group may be only half of the first group.

Several groups of radiators are hot, and several groups are not hot, the main reasons are:

1. The opening of the water supply valve or return valve of the radiator is too small, resulting in too little water entering the unit time.

Solution: 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.

Solution: It is best to change to parallel connection, or increase the circulation pump to increase the circulation 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: the hot water flows poorly and the temperature is unevenly distributed.

Solution: Increase the circulating pump, or try to adjust the opening degree of each valve to evenly adjust the temperature of each group of radiators.
