Why is the water in the radiator black

If the heating season is not hot, most families will go to the heating to put water, but at the beginning it is black water. So the question is, why is there black water at the good end of the heating? These black waters are all from **, let's follow the golden flagship flag brother to find out.

If the heating is not hot, most families will go to the heating to put water, but at first it is black water. So the question is, why is there black water at the good end of the heating? All this black water comes from?

1. The first situation may be that the water in the pipe is very dirty, with some scale or rust. Because the water in the pipe will undergo an oxidation reaction after being heated at high temperatures.

produces black impurities that precipitate in the radiator.

bottom, over time, black water will flow out. What's more, there are a lot of bacteria in it. This must be taken seriously, if the water quality is not good, it will affect health problems.

2. The second situation may be the reason for pipeline maintenance, whether it is the radiator at home or the floor heating, there will always be some damage after a few years of use. In the process of repair, because the interface of the pipeline is open, the impurities in the external soil or the welding slag generated in the welding process may enter the pipeline, and enter our room with the operation of the water supply and return, and slowly accumulate in the room to form black water.

So how can these two situations be resolved? Don't worry, Kim Kim has a trick.

1. You need to drain all the water in the pipeline, and ask professional pipeline maintenance personnel to clean it. After that, the maintenance pipeline is regularly inspected. Carefully clean the heating pipes before heating every year to prevent the generation of black water.

2. Special attention should also be paid to the installation, if the installation technology is in place, it is difficult for some impurities or welding slag to fall into the pipeline during welding, which can also ensure the tightness of the pipeline, and it is difficult to pollute the pipeline in the later stage. Because the water in the pipe is dirty, there will be rust, rust, etc., which will cause the pipe to be blocked, so that the heating effect can not be good.

1. It may be that the temperature difference between the return pipe and the water supply pipe is relatively large, resulting in the blockage of the pipeline, and there are many impurities, and the water in the pipe is black over time. If there are impurities in the pipe, the pipe will be blocked, so the sub-water circulation will be very bad. In addition, the diameter of some pipes is relatively small, and the smaller the diameter, the easier it is to cause blockage, and the heating in the natural home will not meet the requirements, and the pipes will be dirty, and there will be a lot of sediment.

2. Some users have just installed a new pipeline, and there will be a problem of black water at the beginning, as long as the pipeline is cleaned, there will be no similar situation in the later stage.

3. The pipes of the heating company are generally made of iron materials, which will react when encountering oxygen, thus forming some impurities. These impurities are all black, and they look like black pieces of iron over time, which is also the reason why the water inside the pipe turns black.

If you find that the heating effect in your home is not particularly good, you need to check whether it is a problem with the plumbing. If you find that there is black water in the pipe, you should drain it in time, and at the same time, you should clean the pipe again. Once the water is drained, it should not be used for washing clothes or cooking, as the heating company may add deodorant to the water.

The water smells like garlic and cannot be drunk directly.

The heating company's main heating pipes are all cast iron pipes.

The magazine in the water is heated at high temperature and comes into contact with the iron pipe for a long time, and black impurities will be formed after oxidation. After the user heats up, it is deposited in the home radiator.

of the bottom. During the initial heating, if the water pressure is insufficient or there is air inside, unscrewing the outlet valve will create a black flow of water.

The water in the pipes is very dirty, with scale, rust, silt and microbial bacteria, etc., and it is not excluded that the heating company throws other drugs into it to prevent everyone from stealing water, so it is normal for the black one to be black.

Add a certain amount of chemicals to the water, so it will be black. Remind everyone not to use the water in the radiator to wash hair, wash clothes, wash mops and other harmful places for the sake of convenience and saving.

Because the water flows through the pipe, the transmission is relatively long, and the pipe has not been cleaned for a long time!!

Did you add descaler? If you add it, it's normal!

The so-called stagnant water in the heating means that when our heating is not in use, the water in the pipes, that is, the water in the floor heating or the radiator, will still exist in the inside of the radiator and the floor heating.

Black water**: The root cause of black water in the heating at this time is caused by the precipitation of impurities in the water when the water is at rest. With the increase of time, these precipitated impurities will slowly accumulate in our radiators or some places where the circulation of floor heating is not smooth.

So when we put water on the radiator, because the water flow increases, we bring out these debris, and what we see at this time is black water.

There is a problem: due to the precipitation of water at rest, resulting in the accumulation of impurities. If it accumulates too much in one place, it will lead to poor indoor water circulation, which will seriously affect the indoor heating effect.

At this time, it is obvious that we will find that our water supply and return pressure is normal, but the heating effect cannot be improved. If you look closely at the traffic, you will find that the traffic is not up to the mark.

Treatment measure 1: Our conventional method is to release water to the radiator or floor heating. The specific steps to do this are:

Turn on the radiator or one of the connections in the underfloor heating and connect a hose to drain the water. Turn on the water supply and return water to release the water, and at first it will be black water, and slowly it will turn into clean hot water. At this time, it can be said that the clutter inside is basically released, but it is not thorough.

Treatment measure 2: At this time, we can also use high-pressure water for rinsing. Here's how to do it:

Turn off the water supply and return of our indoor heating, then find a place where the air pump can be connected, and connect the air outlet pipe of the air pump to the interface. Apply a pressurized approach to flushing. In this way, the deposited debris can basically be washed away to achieve the ideal flushing effect.

The heating water and boiler are circulating all the time, so let's prevent water from leaking.

The inside of the heating pipe was dirty and the water was contaminated.

Normal. The tap water at home is stopped for a few hours, and then the water is not yellow or muddy, and it will slowly become clear after a while, the reason is the same, the heating management itself is a closed pressure vessel, and it is inevitable to enter some dirt or something when repairing, and the management itself will fall something down after aging and corrosion.

The water purifier is a deep processing of tap water, and its filtration device contains activated carbon and other substances, which will adsorb out foreign substances such as particles, bacteria, and viruses in the tap water, so the water will become particularly bright after being processed by the water purifier, much brighter than tap water.

However, in the process of filtration, the minerals that are beneficial to the human body are also easy to be filtered out, so from the perspective of safety, it is necessary to install the water purifier, but due to the lack of trace elements such as minerals required by the human body, it is not suitable to drink the water filtered by the water purifier for a long time, including the purchase of bottled or bottled pure water.

The heat drain switch is on the water collector.

Specific steps: 1. First close all the valves of the water collector.

2. Use a wrench to remove the nut on the right side of the drain pipe of the water collector.

3. Put the basin ready to receive water, then open the main valve of the water inlet pipe, and then open the water inlet valve of a water distribution pipe and the outlet valve of the corresponding water distribution pipe.

4. Drain water to each water distribution pipe in turn, until the outlet of each water distribution pipe of the water collector has heat to end the water discharge, and finally screw the nut on.

For example, the tap water at home is stopped for a few hours, and then the water is not yellow or muddy, and it will slowly become clear after a while, the principle is the same, the heating management itself is a closed pressure container, and it is inevitable to enter some dirt and dirt when repairing, and the management itself will fall something down after aging and corrosion.

The so-called internal characteristics of the pipe or radiator are the characteristics of the inner wall of the pipe or radiator. For example, the inner wall of the radiator is not particularly smooth, so there may be hanging objects. The inner wall of the underfloor heating pipe is very smooth, but it has an oily layer.

This oiliness is conducive to the transport of water, but there will be the characteristic of hanging dirt.

Black water**: The black water released when we use radiators or floor heating normally is basically caused by the impurities in the hot water supply by the characteristics of the inner wall of the pipe or radiator. Under the condition of normal heating constant pressure and constant speed, these debris will always accumulate on the inner wall of the pipe.

There is a problem: this kind of dirt on the inner wall caused by the characteristics of the pipe or radiator, it will seriously affect the heat dissipation of our radiator. If it is underfloor heating, the heat dissipation of the underground mining pipe will also be seriously affected.

This is the reason why many friends say that the temperature of the heating at home slowly drops after a few years of use. Because the thermal conductivity of the material is blocked by debris, the thermal conductivity is seriously reduced.

Treatment measure 1: The first thing recommended to you is to use the method of pulse flushing. Because pulse flushing is carried out by means of variable flow rate, some dirt attached to the inner wall can be brought down from the inner wall of the pipeline by changing the flow rate, and then all the debris can be washed out.

Treatment measure 2: The second method is to clean the water inside the pipe or radiator, and then quickly open the valve for flushing. In fact, this flushing method is essentially a variable flow flushing method.

The specific operation is to close the water supply and return valve first, find a drain outlet, and unload the heating water in the room. After that, the water supply valve is opened and flushed quickly, and all that comes out is black water.

Kiss, <>

I am glad to answer the reason why the water emitted by the water and electricity radiator is black: if you find that the water released by the radiator is black, it means that the water in your pipe is very dirty, there is some scale or some rust, and more importantly, there are many bacteria, so you must pay attention to it. After the water in the expansion data pipeline is heated at high temperature, the oxidation reaction will form black impurities, which will precipitate at the bottom of the radiator, and over time will flow out of the black water.

It may be that the water pressure in the pipe is insufficient, or there is air in it, and when the heating is first done, the valve that opens the heating will form a black flow of water, which is not a big problem, and then the water is clean. Hope mine can help you! <>

The heating company's main heating pipes are cast iron pipes, and the impurities in the water will form black impurities after long-term contact with the iron pipes after high temperature heating, and after oxidation. After the user heats up, it is deposited at the bottom of the heating end of the home. These oxides are also dark in color, and over time, they look like thick ink.

It is also the main reason why the water in the heating pipes turns black.

In terms of heat calculation**, it is provided to the heating company in the corresponding range, and then the heating company will redistribute it to the heat users of each residential area. I happen to work in a heating source enterprise and have a good understanding of central heating. Let's talk about central heating in a nutshell.

The rust keeps peeling off, accumulating more and more, and finally discoloring the water and turning it into a brown color. Artificially colored, some heating units in order to prevent users from using hot water without authorization, add odorant or colored dyes to the pipes to change the color of the water, so that users do not dare to steal water.

We found that the water that came out of the banquet was very dirty, and it was all black water. So why is there so much black water in underfloor heating? For example, now a friend asks such a question:

Central heating: Where does the black water in the floor heating pipeline come from? The debris and large particles in the water are successively filtered out by the filter installed in the pump room, the filter before the unit enters the house and the filter of each household, and only the finer impurities are deposited in the floor heating pipe due to the decrease in water flow rate after entering the floor heating pipe.

These drugs have a maintenance effect on the pipe network. It will reduce the obstruction of the pipes and achieve less rust. The effect of less limescale.

More favorable for the speed of the water flow. Speed up the transmission of heating, up to the effect of leaking the pants to the heating of the household, these chemicals run in the water, will have a staining effect on the heating. Because the floor heating has not been cleared for a long time, some impurities and rust in the water are deposited in the pipes, and the water will change color.

As long as it does not affect the heating effect, you don't have to care what color the water is. After a long time, you can clean the filter in front of the water separator.

However, many people still know less about these unpopular knowledge of floor heating. My family encountered the situation that the floor heating pipes are released with black water, experienced neighbors saw that I was making a fuss, three or two clicks to find out the reason for me, rust continues to fall off, more and more accumulates, and finally makes the water discolored, into a brown color artificially added color, some heating units in order to prevent users from putting hot water without authorization, add odorant or colored dyes to the pipes, so that the water changes color, so that users do not dare to steal water.
