What should I do if the radiator blackens the wall?

The reason why the wall is blackened is that the convection of hot and cold air above and below the radiator, the hot air is above, the cold air is below, and the particles suspended in the air are slowly attached to the wall above the radiator, and after a long time, the wall will become black.

First: use radiators with a slight effect of radiators, such as die-cast aluminum radiators, steel plate radiators, copper convection radiators or underfloor heating.

Second: add a shield or light yarn above the radiator. This in turn prevents floating particles from entering the wall.

Third: Place glass or wallpaper above the radiator that can easily remove particles.

ps: The Satoria radiator is recommended to use tin foil, place tin foil above the radiator, and cover the part of the wall close to the radiator with tin foil, which has two advantages, one is: the wall is blackened, which effectively blocks the particles suspended in the air and attaches them to the wall; The second is:

With the presence of tin foil, it will prevent the heat emitted by the radiator from being absorbed by the wall, thus greatly increasing the temperature of the room, killing two birds with one stone.

Clean up the walls that have been blackened by radiators.

1. Tools: hair dryer, small brush, detergent.

Method: Use a hair dryer to blow the area to be cleaned, after blowing off the dust, use a small brush to brush with detergent to clean the dust first and then brush.

2. Tools: rags, sandpaper, paint.

Method: The first step is to wipe off the floating ash on the wall with a damp rag;

The second step is to sandpaper the blackened wall;

In the third step, apply the paint evenly from top to bottom.

What should I do if the radiator blackens the wall? These two methods can be stopped, and the walls of the house are in vain for ten years.

There is a certain distance between the installation of the radiator and the wall, and the blackening is not actually too high heat to blacken. This situation is due to the high heat above the radiator, and because the hot air is light, this area will form a suction force on the surrounding air, which will absorb the particles and impurities in the surrounding air and cause wall pollution. Therefore, it is best to wipe the installed radiator frequently during the use season, and do a good job of indoor air quality, which can avoid this situation.

The easiest way is to make a radiator hood (cloth) and cover it on top of the radiator.

Radiators are to be scrubbed often!

When cleaning your home, you may find a small piece of wall above the radiator that is darker than the other walls, which is known as the heating 'smoke' problem. So what causes this problem, and how to prevent it? Let's follow Jin Jin to find out.

Smoked Walls' Causes:

The reason for the heating to blacken the wall is very simple, because the hot air flow generated by the heating is lighter and flows upward, which drives the movement of dust in the surrounding air, increases the adhesion of dust on the local wall, and causes the wall to accumulate more dust and become significantly darker. In layman's terms, because there is too much dust in the room, the hot air flow drives the dust to concentrate, so the general position of the smoked wall is behind the radiator or the upper part of the radiator. Some users encounter radiator smoked wall, may mistakenly think that it is the quality problem of the radiator, and suspect that the radiator is sprayed unqualified to cause the radiator to smoke the wall, which is really "wronged" the radiator.

For the same reason, the wall above the ceiling lamp or chandelier is also darker, because the lamp also has heat, which also heats the air, causing the flow of hot air and driving the movement of dust. In the same way, it is also understandable that the wall near the lap of the desktop computer case is also darker, because the case fan drives the airflow and also drives the dust, resulting in a darker wall.

Precautionary measures: 1. Wrap a heating hood.

This method used to be common, but it has now largely been phased out.

Because in the past, the main reason for wrapping a heating hood was that the heating was not good-looking, and now the heating shape is basically very beautiful, and no one is willing to wrap it. Nowadays, many of the heating is centrally heated by households, and the water temperature is lower than the water temperature of the boiler heating in the past, and the heating cover is not conducive to the heat dissipation of the heating, so we do not recommend wrapping the heating in the decoration now. Wrapping up heating will have the following drawbacks:

1) Poor heat dissipation, reducing heat by 30% or even more than other heating, increasing heating costs, especially for household metering and independent heating. (2) The cover is dirty and dirty, and it cannot be cleaned. Dust and bacteria are not good for human health.

2. Put a towel or cloth on the heater.

This method has some effect, but it is generally not good. The towel has poor air permeability, which disperses the heat flow, so that the air flow of dust is also dispersed, and the wall cannot be blackened in a concentrated manner. And it can only prevent the middle from being able to prevent a heated wall outside.

3. Bring an air purifier.

The air attack air purifier for the heater that can filter dust is used above the heating to filter out the dust in the air, and the rising air flow does not change the flow direction, but there is no dust anymore, so it will not smoke the wall. It doesn't blacken the sides or top like you would with a board on top. This method is certainly a little more advanced than other methods, and it is a costly one.

Fourth, anti-fumigation wall radiators.

The installation of smoke-proof wall radiators greatly and effectively eliminates the yellowing and blackening of the wall, and the protection of the wall is almost perfect, which is the best choice for the taste. Dahua meets the needs of modern high-end people in their home life.

In winter, many homes use radiators. However, if the radiator is used for a long time, the wall above the radiator will often be smoked yellow or even black, which is very difficult to clean off, even if it is cleaned and the surrounding wall will have obvious color difference, especially affecting the appearance. So what to do if the radiator smokes the wall black?

1. You can use a hair dryer at home to blow off the blackened place first, blow off the dust on the blackened wall, and then use a small brush to brush on toothpaste or baking soda and other detergents, and wipe the dust clean before brushing.

2. If the radiator has only been used for 1-2 years, you can use a semi-dry rag to wipe off the blackened part of the wall. If you use it for a long time and can't wipe it clean with a damp cloth, you can wait until the heating is finished and then use sandpaper to polish the blackened wall. Once the black is sanded off, apply the new paint evenly from top to bottom.

Note that the new paint for partial repair will inevitably have a certain color difference with the original wall.

1. You can try to clean your home, especially under and near the radiator, to reduce dust, so as to eliminate the substance of the smoking wall and solve the problem from the root.

2.Dust and heat that drifts upwards while heating can avoid prominent locations in your home. Choose areas such as the bottom of the bay window, under the window, etc., so that dust and impurities adhere directly to the glass, and wipe it frequently to recover.

3.Add a shroud to the heater. A shroud is similar to an air conditioner's shroud.

Change the direction of the airflow so that impurities do not easily accumulate on the wall. But it is not a heating hood, which can greatly hinder normal heat dissipation, and it cannot be covered during the heating season. In the same way, it is also possible to put a small baffle on the radiator.

4. Put a wet towel on top of the heater, so that the heat will be dissipated, but the dust will be directly adsorbed on the towel to avoid blackening.

Generally, the location of the smoked wall is behind or above the radiator. Because the radiator heats the surrounding air, the hot air then rises, driving the dust, smoke and particles in the air to flow, causing impurities to attach to the walls and surfaces of objects above or near the heating and air conditioningOver time, they turn black.

The water inside the radiator is specially treated softened water to protect the pipes. The softened water is alkaline and causes slight corrosion to the human body, but does not darken the walls. Because air convection will absorb dust, when the radiator is conducive to heat dissipation, the convection of cold and hot air is obvious, and there is a lot of dust, which is easy to cause the wall to blacken, so as not to blacken the radiator.

The radiator is heated by its own heat, heating the surrounding air, hot air rises and cold air falls. Generally, the hot air is dry, and in the process of upward flow, some dust will be adsorbed on the wall, which will cause the phenomenon of radiator smoke on the wall, which is actually dust adsorbed on the wall. Then use sandpaper to carefully polish the wall blackened by the radiator, to choose a finer sandpaper to sand, the thickness of the general sandpaper is written on the back, the larger the general value, the finer the polishing, the smoother the surface, the rougher the value.

We buried the pipes in advance, installed radiators on the walls, sent hot water through the boiler or circulating water heater to the radiator position, and then the hot water returned to the hot water conveying equipment through a circulation; The blackening of the wall is mainly due to the high temperature of the radiator during heating, the water supply temperature in the radiator is about 70 to 85 degrees, and the radiant heating will have hot air flow to move upward. The hot air generated by the heating is lighter and flows upwards, driving the movement of dust in the surrounding air.

While raising the indoor temperature, it not only lowers the indoor humidity and causes discomfort to people, but also blackens the wall above the radiator. Especially now, most of the walls of the room are painted white, and a slight discoloration is obvious, which seriously affects the beauty of the wall. Because the radiator heats the surrounding air, and then the hot air rises, driving the flow of dust, smoke and particles in the air, so that impurities are attached to the walls and surfaces above or near the heating and air conditioning, and it will turn black after a long time.

I think we should think about how to prevent blackening, clean the house frequently, so that we can reduce dust, this is the most fundamental way, and you can also buy a breathable fabric material to cover the radiator. According to the principle of air convection, the best place to install the radiator should be under the window. This blocks out the cold air coming from the windows, as the glass is less insulating than the wall.

Heating and recirculating cold air into the room increases heating efficiency.

You can put a wallpaper on the wall of the radiator or you can put some wooden boards to block it, as long as the heat is separated.

The solution is to move the radiator away from the wall, or put a protective layer on the wall, or wrap the radiator in a box.

In fact, we can make a radiator cover for the radiator, which can not only improve the aesthetic effect, but also solve this problem, and the cost is not very high.

In the application of ambiguous tablets in some homes in China, the wall will be "blackened". What should you do in two years for a newly renovated house? Share with you how to solve and prevent the problem of radiators "blackening" the wall.

The flakes heat the surrounding gases according to their own calorific value, hot air and strong cold air. In general, hot air is coarse. During the upwelling process, some dust will be sucked up on the wall, which will cause smoke on the wall and cause the radiator to be damaged.

In fact, dust is adhered to the walls.

If it is putty powder wall, you can polish it with water sandpaper, and you can batch putty again if necessary. If it is a painted wall, you can sweep the wall with a soft brush. If you can't use a hair dryer, you can only use a sticker for temporary healing.

In the middle and later stages, the stains can be sanded and polished and brushed, or they can be hand-made and painted or covered with decorative paintings on the wall.

When the baffle is used on top of the radiator, hot air can be drawn from the wall to reduce the problem of the radiator smoking on the wall. The key is the dust in the house. If the dust is not large, this problem is not possible.

This problem is caused by a large amount of dust in the room, and during the winter heating period, the humidity in the room is low, and the dust is very easy to fly. It is often advisable to clean the dust around the radiator and the dust inside, use an air purifier, or often clean the wooden floor and sweep the wall, and the radiator should not be installed too close to the wall, which can easily cause smoke on the wall. In addition, the flow rate should be installed around the perimeter of the radiator cover to prevent the hot air from rising immediately and close to the wall.

At this stage, the most common and effective method is to install a stop whose length and overall width cover only a few radiator points in the radiator. It's best to opt for tempered laminated glass or stainless steel sheets for faster care and longer lifespans. Dirt removal reduces cyclone elevation standards caused by radiator heat.

Due to the lack of cyclonic standards, the seepage of dust around the enclosed radiator will largely subside, otherwise the oscillations placed on the radiator will cause a lot of dust.

<> "In the process of using radiators in some of our homes, there is a phenomenon of "blackening" of the walls. What should we do in a few years for a newly renovated home? Share with you how to solve and avoid the problem of radiators "blackening" the walls.

Radiators heat the air around them by using their own heat, hot air, and cold air. Usually, hot air is dry. In the process of upwelling, some dust will be adsorbed to the wall, which will cause the wall to smoke and produce the radiator phenomenon.

In fact, dust is stuck to the wall.

If it is a putty wall, it can be sanded with fine sandpaper, and the putty can be re-scraped if necessary. If it is a latex painted wall, you can sweep the wall with a brush. If you can't blow the air with a hair dryer, you can only stick it on as a temporary **.

When it is renewed, the dirt can be sanded and painted, or it can be painted by hand or covered with paintings.

When you make a partition above the radiator, you can direct hot air out of the wall to reduce the problem of the radiator emitting smoke on the wall. The key is the dust in the house. If the dust is small, this problem does not occur.

This problem is caused by too much indoor dust, which tends to fly when the indoor humidity is low during winter heating. It is often advisable to clean the dust around the radiator and the dust inside, use an air purifier, or clean the floor and sweep the walls frequently, and the radiator should not be installed too close to the wall, which can easily make the wall smoke. In addition, the flow rate should be installed around the radiator top cover to avoid a direct increase in hot air and rise close to the wall.

Currently, the most widespread and efficient method is to install a stop whose length and width cover only multiple radiator points in the radiator. It is best to choose tempered glass or stainless steel for better care and longer lifespan. Decontamination reduces the airflow rising conditions generated by the heat energy of the radiator.

Due to the lack of airflow conditions, the turbulence of dust in the vicinity of the enclosed radiator will largely disappear, otherwise, the disturbance placed on the radiator will generate a large amount of dust.
