How to reduce the temperature of the batteries It's hot in the apartment during the heating season. What to do

A painful question was shared with the readers of Onliner.by by a user under the nickname _maria502_. A girl who lives with her family in a panel ten-story building suffers from "overheating" every year - regardless of the temperature outside the window, the batteries in her apartment are "fried" like in the most severe frosts. The hostess tried to deal with the temperature outrage with the help of appeals to the housing department.

Every heating season, and especially at its beginning and end, when it is already relatively warm outside, overheating occurs in my apartment. But not quite overheating, but a very unbearable heat, and this spring it even reached 30 degrees. Every time at such extreme temperatures, with great hope of salvation, I call ZhES-97 and ask for help: lower the temperature of the batteries. By the way, the batteries are in the walls.

Every time in the housing office, they solemnly promise me to reduce. But they never do it just like that, by a simple application. For example, this spring, namely, starting somewhere from March 14, it began to warm on the street. Well, at home, the batteries worked the same way as in subzero temperatures. I determined this by touching, more precisely, by the inability to hold on to the battery from the heat with a hand, both in subzero temperatures and at +10, and now at +18.

I called the ZhES - no result. Knowing from the experience of previous overheating that they would wait until the heating was completely turned off, I began to apply to the ZhREO of the Central District. There I was professionally sent to call different numbers from one specialist to another. Which I did. In a week. Everyone promised to help me. As a result, the batteries fried unbearably, and the air temperature outside the window warmed up to +18. ZhES sympathized, said that we did not have automation and we needed to manually adjust the valves. I say: what questions, is it real, to adjust the valves? They say that, probably, yes. It is recommended to open windows.

The windows, by the way, are open for all tenants above our and under our apartment - everyone regulates the heat in their apartments as they can. ZHREO generally pleased: they recommended to be patient. Everything can be understood and forgiven, but the nuance is that I have a small child who reacts sharply to drafts, which are inevitable with open windows, he instantly gets sick. You can take the child out of the room for a while and ventilate, you say, but the problem is that with such a supply of heat, as soon as you close the window - 1-2 minutes and again the greenhouse effect and the temperature on room thermometers is 27-28 degrees. You can't open the window at night.

Dripping in sweat, we treat a child who has fallen ill from these temperature controls: it is impossible to go outside. As a result, I come to the housing department, I ask for a book of complaints, they ask me not to write, as they can punish the director, but he is so good. I understand that the employees feel sorry for him, but no one except me will feel sorry for me. I start writing, a good director appears. Emotionally I tell him about my problem, he is unhappy with my story and thinks that I want to swear. Apparently, it does not imply that I am trying to somehow defend my rights to a normal existence in the apartment. Says, write what you want, I don't want to talk to you.

The plumbers who were present begin to understand the tragedy of the situation and “take pity”: they go to the basement to adjust the valve. An hour after my trip, the phone rings, and the plumber says: that's it, I've done everything, just don't complain if it gets cold now. I ask: have you completely turned off the heating? He says: what was left for me.I, he says, felt sorry for your child, so I pushed it back.

I would like to touch upon the material component. Now a lot of people write that the population pays for heating only a small percentage, the figures are different. The rest is paid by the state. This topic arises regularly. So, I come to the question: why is the ZhES, a state organization, not interested in saving public funds? A whole department for energy efficiency has been created, a bunch of people are accepting applications for reducing the consumption of heat energy, in the housing department, in the housing maintenance department. But the plumber goes to reduce the heat only after he sees the person who announced, and then after decides whether he feels sorry for his children or not? "

With the question why ZhES-97 is not interested in economical use of heat energy, we turned to the director of the institution.

- As practice shows, in such apartments, not 30-31 degrees, but only 25 - because people do not ventilate the premises, and they also install air humidifiers. Therefore, you come and check, but in the apartment neither the window nor the balcony ever opens. Plumbers went to this apartment this morning to cut off the heating supply. I only had to wait for Monday, as I explained to the hostess, when a qualified master who was on leave would come. In her apartment, the temperature will decrease, but because of this, others will suffer, because there will be an undersupply of heat. The process, in general, is not laborious: about an hour of work. There is no way to adjust the system - only to reduce it. There is mechanical equipment in this house, it is not old, but it can only be adjusted manually,

- explained Vadim Solovey.

What do we usually complain about to city utilities when winter comes into its own? That's right, most of the complaints are about heating. It often gets too cold in the apartments, and we start asking the utilities to do something to make the batteries at least a little hotter.

But in the winter of 2020, in many regions of Russia, a surprisingly warm winter stood out. At times, the average temperature outside the window exceeded the norm by ten degrees at once. And utilities do not always have time to respond quickly to such changes.

As a result, many residents of Russia for the first time faced such a problem as overheating. This word refers to a situation when employees of heating networks work too hard, as a result of which the temperature inside the apartments exceeds all established standards, causing discomfort among citizens. By the way, the temperature in the apartment is 22-24 degrees above zero on the Celsius scale. Oscillations of plus or minus two degrees are considered permissible. If the temperature does not meet these standards for a long enough time, you can raise a noise with a clear conscience.

The situation, to put it mildly, is atypical for Russia, and therefore few people know what can be done in such cases. And there can be several outputs at once. Which one to choose will depend on the specific situation.

In a simple way

The easiest way to cope with the increased temperature in the room is for those who have a radiator system in the apartment with adjustable hot water supply. It is enough just to cover or completely shut off the water supply to the radiator, and the thermometer in your apartment will creep down before your eyes.

The balancing valve can also be installed on the heating riser. As a result of its complete or partial overlap, the temperature in the dwelling will decrease. Having found the best option, you can easily bring the home climate to the required norm.

This, of course, will solve the problem with the high temperature in your apartment. However, this is only suppression of symptoms, when you can pay attention to the cause of the problem. There is another unpleasant aspect of overheating - every extra degree our radiators heat up is money that we overpay for heating.

Maintenance and troubleshooting

In district heating systems, ordinary industrial water acts as a heat carrier, the purity of which is far from ideal. Having passed along the heating main, to the elevator unit and risers, by the time the water is in the battery, it is enriched with various suspensions, which are deposited in the radiators.

Because of this, the devices need to be rinsed every few years.

This process requires access to the flush valve located in the lower corner of the radiator on the opposite side of the piping. Thus, if there is no free access to the device, you need to either remove the protective screen (and this is not always possible), or put up with poor heating efficiency. For this reason, when choosing how to close the battery in the room, you should give preference to such a product that will allow you to freely access the heating device.

We complain to all authorities

In order not to pay extra money for heating, it is necessary to draw the attention of utilities to the problem of too hot radiators in the apartments of your house.

To begin with, you should try to influence the situation through your management company. Formally, the residents of the house are not directly connected with the workers of the city's heating network, therefore, it is not the owners of the apartments that should communicate with them, but the management of the management company, which is responsible for a particular house.

If a complaint to the management company has been written, but it did not bring any result, you can contact the higher authorities, which are the housing inspection and Rospotrebnadzor. It is important to draw the attention of officials to the fact that it is hot in the house, and the appeal to the management company did not lead to any results. Not the fact that even such measures will be able to quickly solve the problem. Rather, it will have to be resolved due to natural conditions or a planned decrease in temperature in the network. But by doing this, you will show the management company that you do not intend to put up with their unfair work, ensuring that your future appeals are carefully considered.

There is one nuance in this solution to the problem. It is important that you are not the only one who turns to the management company, and later to higher authorities. You need to make sure that the rest of the residents of your home also face the problem of overheating. After all, there are often cases when it is too hot in apartments on the first floors of a house, and residents of the upper floors complain about the cold, which makes the utilities work harder. And so it turns out overheating.

In this case, the problem cannot be solved by simply adjusting the heating intensity - the management company will have to carry out work on balancing the heating system in the house so that the temperature in the apartments on the upper floors is the same as on the first floors of the house.

Radiator masking methods

If the temperature in the apartment is completely satisfactory, but only the appearance of the batteries worries, then you can use one of the decor methods. The main thing is not to harm the heat transfer process and observe several important points:

The radiator may require repair or replacement, so you need to think over the decorative design so that in the event of an accident, the battery can be easily removed. Plumbers who regularly face problems with heating devices generally recommend using only side screens that simply move to the side.
The main threat from a radiator is a possible leak at the junction with the heating pipes. Therefore, the second important nuance is the availability of connection nodes, which can be ensured by providing a plastic door in box designs.

Using wallpaper

Typical heating radiators are painted white and look good only against white walls.If the walls are dark in color, but without a pattern, the radiators can simply be repainted. Only heat-resistant paint can be used.

Drawing on the walls complicates the task... Using a stencil and paint, it is easy to duplicate a simple pattern on a battery. If the pattern is complex, you can cut pieces from the remnants of the wallpaper that match the sections and stick them on the radiator.

A special way to decorate a battery is decoupage. Handicraft supplies stores sell vinyl based stickerswhich does not deform under the influence of temperature. For decoupage, you can use not only ready-made patterns, but also create your own from improvised materials: fabric, paper, hot melt glue and even beads.

Fabric screen

Women with good sewing skills often independently make covers for radiators made of fabric.

Extreme measures

But it often happens that there are no control valves either on the risers or on the radiators in the apartment, and there is no urine to wait for the actions of the management company and answers from housing inspections and Rospotrebnadzor - it's too hot.

In such cases, you will have to act by "folk" methods. The most popular way to regulate the temperature in an apartment is through open windows. You can try to find the optimal solution using this move. It will be much easier to do if you have modern plastic windows with micro-ventilation mode installed in your home. Such windows leave only a small gap through which cool fresh air enters the apartment. This will prevent the apartment from cooling down and the temperature drop too much.

There is one more case - blankets. It is believed that by covering the radiators with blankets, you can lower the average temperature in your apartment. The logic is simple: the material from which the blanket is made has a minimum heat transfer coefficient. It will take heat from the radiator without "giving" it to the atmosphere in the apartment. The way out, to put it mildly, is not the most reliable, but, as they say, without fish ...

One of the most effective ways to combat the heat of the summer is with an air conditioner. It is able to cool the air in the room and maintain the desired temperature.

Of course, this method has disadvantages - the air conditioner requires a complex and expensive installation. However, you can purchase a mobile air conditioner that does not need to be installed.

When it is not possible to purchase and install an air conditioner, you can use another device - a fan. With its help, the hot season is much easier to bear.

If the apartment windows face opposite sides of the house, you can open them and create a draft. But you need to remember that being in a draft for a long time can be dangerous to health.

It is necessary to limit the penetration of sunlight into the room. If the curtains or blinds are not effective enough, you can use a mirror-like reflective film by attaching it to the window. It will reflect infrared and ultraviolet rays. This film is especially effective if your windows are facing the sunny side.

The heat in the apartment is more difficult to tolerate if the air in the room is dry. It needs to be moistened. To do this, you can use wet towels or sheets, hanging them in the rooms. You can also find humidifiers in stores that will automatically maintain humidity.

A constant supply of fresh air will help you withstand the heat more easily. Of course, open windows partially help in solving this issue. But there is also a more efficient and technologically advanced way - to install supply ventilation valves. They will ensure correct air exchange around the clock.

Correct installation of ball valves. Tips.

Install, replace # 171; ball # 187; crane in this there is nothing complicated. Anyone can replace him.Ball valves got their name due to the fact that a ball is installed inside it that blocks the pipeline through which the working medium moves. Ball valves are simple and reliable to use, thanks to this they have gained popularity.

The main thing is to choose the right one for you. Their sizes are standard and are measured in inches. the design is simple. The body consists of two parts, connected by a thread, inside # 171; ball # 187; with a through hole, stem, oil seal, handle. The most popular, so to speak, at home are the sizes: 1/2 # 8242 ;, 3/4 # 8242 ;, 1 # 8242; there are more. Before buying, I advise you to find out the country of the manufacturer. It is advisable to buy Italian, Spanish cranes. They are of higher quality and stronger. Chinese, although visually they cannot be distinguished visually, but you can pick them up by weight, the Chinese will be much lighter than the European ones. You need to install the tap correctly. If it is not installed correctly and breaks down during operation, you can get a leak. As indicated above, the body consists of two parts, one of the sides is molded in one piece and the other part is its nut, which is screwed along the thread to one another. The one-piece cast part of the valve must be screwed to the pipeline that comes out of the riser. In this case, if the valve breaks in half under the influence of different conditions, you will have the opportunity to quickly shut it off because the ball itself inside will remain on the one-piece cast part of the valve. Otherwise, a ball will fly out and one nut will remain on the pipeline. Cranes are afraid of frost. If your taps are installed somewhere on the street. Let's say on a watering pipeline. For the winter, naturally, the water is drained and it is better to leave the tap in the open position. Since water can collect somewhere, the remains will not all go away and the tap will simply burst.

Shut-off valves on water pipes - inattentive attitude to this thing can cost you a significant amount.

Imagine this: a tap on a cold water supply pipe breaks down. Obviously, there is a fountain in the apartment. And if you are on vacation, then the fountain quickly turns into a lake and all this flows to the neighbors below. And if they are also on vacation / at work or something? Another floor below. And so on. You can figure out the financial side of this case yourself.

The tap is where the leak is most likely to occur. The pipes are welded securely. If not, it will be noticeable immediately, but problems with the crane accumulate gradually. So let's try to figure out which of them is more reliable in operation.

Ball or valve?

For an apartment, only these two options are possible. Available at any plumbing store, there is an assortment for pipes of different diameters. We look at the pros and cons of each.

Valve

The main plus is maintainability. And this is the main disadvantage. Such a crane is a little more complicated both in the device and in operation. It needs to be twisted and unscrewed, often you don't want to bother with this, and besides, the gaskets and seals wear out regularly, the oil seal begins to leak. We changed the gasket - for the time being, everything is fine again.

The valve can be used as a shut-off and control valve. Ball only shut-off. This is an iron rule - the ball valve has only two positions: open and closed.

Ball

Easier in design and operation. They turned the flag - and it's done. There are compact flags (butterflies). They are convenient in that they do not take up extra space (the butterfly does not protrude beyond the dimensions of the pipe).

What to do if the apartment is hot in winter

In winter, some homes have very hot radiators. The air conditioner is powerless in winter - the outdoor unit must work at positive temperatures. But he is able to help in early spring, when it is already near zero outside and the radiators are still hot.

The most effective way to deal with excessively hot batteries is to install thermostats or ordinary shut-off valves on them.With their help, you can adjust the water flow. As a last resort, just block it.

If this is not possible, you can open the windows. But in winter it is fraught with the danger of catching a cold. If you open the windows for a short time, then after a while the air in the room will reheat and the heat will return.

The radiators can be covered with damp towels or sheets. This will humidify the air and lower the temperature of the batteries. There is only one drawback - the sheets dry out quickly and need to be constantly wetted.

Another option is to wrap a thick blanket around the battery. It will act as a heat insulator and help lower the temperature. And next to the battery, you can put a jar of water, which will evaporate and reduce the dryness of the air.

The management company is responsible for regulating the temperature of the water that is supplied to your home. You can contact her with a request to reduce the temperature of the coolant. If your request is ignored, you can file a written complaint with Rospotrebnadzor.

The weather never ceases to amaze and surprise. Frosts are replaced by thaws and vice versa thaws are replaced by frosts. Likewise, central heating (DH) never ceases to amaze. When the frost is heating batteries

barely warm. When the temperature outside is above zero, they are heated so that you can fry eggs on them.

Batteries are very hot

Heat carriers (hot water) are supplied to the houses from the central heating station (central heating point). One central heating station can provide heat to a dozen houses or more. The temperature of the coolant is automatically regulated by special sensors, which increase or decrease it depending on the air temperature outside. Very often, the automation does not work and all adjustments must be made manually.

So, if in the apartment and all the time you have to keep the vents open, then most likely these same sensors are not adjusted or do not work. What to do? Call your ODS and ask to call a specialist of OJSC MOEK, only when talking with the dispatcher, state in detail the very essence of your appeal.

The dispatcher is not interested in such details as in what form, you walk around the apartment or that you are sweating. He is only interested in specific facts. And that's it!

It may and most likely happen that everything remains unchanged. The thing is that the organization of OJSC MOEK adjusts its equipment only in case of mass circulation of residents, and does not pay attention to isolated cases.

But the good thing is that it ends well. The temperature of your batteries dropped and you breathed a sigh of relief. But don't flatter yourself. Everything can return to normal. What is good and comfortable for you will not necessarily be good and comfortable for others. And once again, touching your radiator, you, burnt, pull your hand back. Don't rush to spew curses. It so happened that another tenant or tenants in your house complained about poor heating. It should be noted that the temperature in the apartment should not be lower than + 18 0 C. In this case, there is nothing left to do but raise the temperature of the coolant to the initial one.

This can go on for a long time. Some will complain that they are hot, others that they are cold. The thing is that it is impossible to adjust the temperature of the central heating batteries in a single apartment because its heating system is built into the general heating system. This can only be achieved by installing modern heating radiators with temperature controllers. True, there are two more ways - to wait until frosty weather sets in on the street and the temperature in the apartments becomes comfortable for everyone, or to force MOEK to carefully monitor its equipment.

The question of how to hide the battery in an apartment from excessive heat is often found on the Internet. Various thematic and simply everyday forums are full of such messages, giving homeowners valuable practical advice. You can refer to some of them.

Heating in the apartment. How to properly close the battery for the summer

I continue to talk about heating in an apartment or in a house.

I am repeatedly asked about what to do with the battery after the heating season is over? In what position should the taps be left, both close or only one?

Let's take a closer look at everything.

Heating in the apartment

We will consider heating in the apartment on the basis of this picture here:

I specifically cited two options, since someone may have a crane on the jumper, and someone does not. You can read more about a jumper (or bypass) with a tap in the article: Heating circuit. Do you need a bypass valve? And now we will talk about something else.

Here comes winter, we turned on the battery, opened the jumper and our house is warm and dry ... Beauty! A battery that is called a spar! But sooner or later, winter ends, and in the front of our staircase we see an announcement about the shutdown of heating. What do we do with the battery?

What if you don't turn off the taps at all?

This option is not very good. The fact is that at the moment of starting and stopping the supply of hot water, all rust flows through the pipes. Hence the conclusion, if everything is left as it is, then the dirtiest water can pass through the battery, and in the worst case, the battery will become clogged. Not 100% of course, but there will be little pleasant.

Here is a powerful catalog of heating radiators with the possibility of selection by price, manufacturer, power consumption, material, number of sections, overall dimensions.

The simplest way

Cast iron radiators, widely used in typical apartments, are the best way to heat living quarters. However, such heating devices also have their disadvantages, mainly associated with the absence of a thermostat and an excessively high return of stored energy. You can consider ways to optimize the operation of cast iron radiators, if any in your apartment.

The simplest and most effective material for eliminating excessive heat transfer from a cast-iron battery is an ordinary blanket placed on the radiator planes. Close the battery with them will be a matter of seconds for you. The possible predictable skepticism of many Internet users is associated, first of all, with a poor knowledge of the physical processes described in the school curriculum.

Reduced indoor humidity will be a minor side effect. It can be easily eliminated by purchasing an air humidifier (its average consumption in a typical apartment is up to three liters of water per day) and a psychrometer - a device that controls the level of humidity in the room.

Do not use the vents as a way to lower the room temperature, they can only be opened to naturally ventilate the room. Otherwise, the presence of very dry air in the apartment can lead to unpleasant consequences for the nasopharynx and skin. At the same time, the heat escaping from the room will not significantly reduce the degree of warming up.

The rationale for this advice lies in the physical processes that occur when cold street air enters the apartment. This air, which has a low level of humidification, heats up, passing through the window into the room, and reduces the absolute value of humidification. Accordingly, an increase in the humidity of the apartment atmosphere will occur with the help of your breath and skin, taking away the water it needs from the body.

What happens if you turn off both taps?

In this case, it is ideal to turn to the laws of physics. Today we have hot water, and tomorrow it will be turned off. We took and closed both taps.What's going to happen? While the water is hot, it will completely fill the battery, but as soon as the water starts to cool down, its volume in the battery will begin to decrease. Reducing the volume in the battery will create a vacuum there.

And what is a vacuum, and why is it so terrible? All of us in childhood, for fun, pulled air from a plastic bottle. Remember what happened? The bottle squeezed. The gifted ones were able to flatten it very strongly. What's happened? And what happened was that we sucked air out of the bottle, lowering the pressure. Of course, there was still a long way to the vacuum, but even in this case, the bottle was strongly deformed. If you connect a pump to such a bottle and start pumping out air to the end (to vacuum), then the bottle will simply be compressed to a point. So imagine how much pressure your battery will experience after a vacuum begins to form inside it. In the worst case, it will deform, in the worst case, it will crack. Therefore, after the end of the heating season, never turn off both taps!

Alternative ways

One of the alternative ways to protect against excessive heat in a residential area is to purchase and install a special valve. Such a simple device allows you to regulate the level of heat supplied to the battery and save its value in ruble terms. The principle of saving becomes important for apartment owners, since heat distribution will become possible depending on atmospheric conditions.

The current state of the market for plumbing fixtures and fittings makes it possible to purchase a special protective screen operating on the principle of blinds. One turn of the shutters of such a screen helps to reduce the amount of heat energy distributed throughout the apartment, as well as minimize the risk of burns from an unnecessarily hot battery. Another advantage of the louvred screen placement is the simplicity of its design, which makes it possible not to carry out complex installation work. Installation of this kind of device will not take more than 10 minutes of your time.

The most radical way to limit the supply of heat to your apartment is to contact the office of the management company. Such treatment will reduce the thermal effect of the apartment battery by closing the corresponding common house valve. This method is not a panacea if you only need to limit the heat supply to the apartment. Using this option will also affect your housemates, who may not be hot.

The tap on the radiators in which direction to open

The valve for the radiator allows you to control the flow of the circulating coolant, including overlapping it in case of checking or flushing the batteries.

With this fixture you can turn off the radiators without pressure testing the main heating system.

It is directly related to the design features of this element and its installation. The crane is a ball with a through hole.

The operation of the crane is controlled by means of a handle fixed to the ball by a rod.

Important! For mounting the device you need to choose the location correctly so that turning the handle does not interfere with other devices of the heating system in the future.

Valve and pipe diameters must be identical.

Fixing the device must run in parallel as it is twisted using tow or a special tape. They provide the mechanism with additional protection against leaks. The correctness of the installation is further checked by supplying a water pressure.

Photo 1. The device of a ball valve for regulating the temperature in the heating radiator. Arrows indicate parts of the product.

Actuation of the handle facilitates the movement of the mechanism around its own axis. Rotation of the ball bore to fittings and pipe entries makes possible the circulation of the coolant through itotherwise the fluid flow will be blocked.

The ball in such mechanisms can be fixed and movable. In the first case, it is attached to the stem so that it remains completely static. The tightness of such a connection is ensured bolts or disc springs.

The movable ball is able to move depending on the degree of water pressure on it... Due to this possibility, this type of mechanism is more widespread than the first.

This is done to supply the maximum possible amount of coolant in order to provide the room with heat. To adjust the mechanism requires turn the handle parallel to its own axis and to the pipe.

For convenience, there are protrusions on the valve body that indicate restrictions on the degree of its opening. This is done counterclock-wise.

This action completely stops the circulation of the coolant. It is required to do this when it becomes necessary to reduce the temperature of the radiator to a minimum, for example, in summer.

The handle of the device is in the "closed" position should form an angle of 90 degrees with its axis and the pipeline. In accordance with the projections, the movement of the handle to stop the circulation of the liquid should be performed clockwise.

Reference. In both situations, in the absence of a handle, it is possible to determine the position of the crane undercut... If it is aligned with the pipeline and the mechanism itself, then its position is "open", otherwise the fluid flow is blocked.

Often this situation arises if periodically, as a preventive measure, do not change the position of the mechanism and do not develop it. Before taking any directed actions to repair the device, it's worth trying to do it with your hands.

Attention! It is necessary to know in advance what the crane is made of, since the use of additional mechanical tools can cause irreversible damage to the mechanism.

Renovation starts with unscrewing the fixing nut and removing the handle. The top of the stem is located under the handle.

Some device models have clamping sleeve for hexagonwhich puts pressure on the oil seal. If the rod turns only by applying force, then the fixation of the sleeve is made a little freer.

At the same time, education is quite common. small drips water at the top of the tap.

Then with using an adjustable wrench with slow movements from side to side, the stock is developed.

Important! It is dangerous to exert extra effort or to speed up recovery work. This can lead to to the process of complete deformation of the ball or the mechanism as a whole.

The final stage of the repair process is putting the handle back... A trial turn of it to the protrusions of the permitted degree of opening allows you to determine whether it is possible to fix the pressure sleeve. The final adjustment knob is installed in place only after a positive test result and checking the mechanism for leaks.

To avoid further unpleasant consequences in the form of a crane breakdown, you should not use a device made of silumin, with a wall thickness of its branch pipes less than 2.8 mm... At the same time, it is worth paying attention to products with a high level of quality, made by European or Turkish manufacturers.

Watch a video on how to regulate the temperature in a heating radiator using a tap.

Before putting it into operation, you must make sure the sealing is done high quality and reliable. This will avoid possible unpleasant moments, for example, a system crash or breakdown. The procedures for direct use of cranes and their repair are simple, you just need to choose the right timeso that the water temperature is not too high. This is due, first of all, to certain safety measures and additional convenience of the working conditions.

To create a functional and efficient heating system, attention must be paid to each element of the circuit - the boiler, radiators, pipelines, as well as battery taps. Broadly understood, a radiator faucet is a specific type of shut-off valve used to optimize the heating system of apartment buildings and private properties.

By installing a tap on a heating radiator, the property owner gets several practical advantages at once:

the ability to completely turn off the heater to change the configuration of the circuit or carry out repair work;
smooth adjustment of the level of coolant supply to the heater;
elimination of air congestion by air discharge;
the possibility of opening the circuit and regulating its patency;
achievement of optimal indicators of heat transfer of batteries.

Various taps for heating can have different purposes, therefore, the installation of devices is carried out in the areas provided for by the project. As a rule, in the heating scheme, clear recommendations are given as to which type of shut-off valves should complement the various types of radiators connected to the circuit.
Failure to follow the recommendations can result in a decrease in the performance of the heating system.

Therefore, it is better for the owner to buy a heating control valve provided by the project. A radiator-mounted bleeder valve helps prevent air from radiators and avoid cold spots.

When choosing a tap for a radiator, you need to know some of the operating parameters of the system. It will help you make the right choice of the diameter of the pipelines used for connecting the batteries, the operating pressure in the circuit and the desired method of mounting the device. As mentioned earlier, the installation of taps on heating batteries is carried out in accordance with the heating scheme, while the decision to install a certain type of crane in the circuit is made after the type of batteries and their location in the circuit have been determined.

The following types of cranes are currently in use:

Mayevsky crane;
ball valve;
flushing valve;
balancing crane;
faucet with thermal head, etc.

When replacing taps on heating batteries, a Mayevsky crane can be used instead of traditional shut-off valves. This element does not differ in high cost and complexity of the design, but it allows to significantly optimize the operation of the system - to eliminate the crackle in the radiators and release air from the circuit. Before the seasonal start-up of the system or during the elimination of airborne radiators, this type of shut-off valve allows you to quickly release air.
When buying a Mayevsky crane, you should take into account its specifics:

the device has a small bandwidth;
the crane has a long service life and is resistant to physical wear;
there are various taps designed for a screwdriver and for a special key;
in some taps, the stem can be completely unscrewed and provoke a coolant leak from the radiator.

This type of shut-off valve can open and close the flow of the coolant in the pipeline. The design of a brass or steel device provides for the presence of an absolutely smooth ball inside, which, turning 90 degrees, opens and closes the circuit. Inside, there may also be Teflon bushings to optimize the operation of the shut-off valves.

ease of use;
affordable cost;
minimum hydraulic resistance in the open position of the valve.

It is also worth understanding that the ball valve is a device for locking the circuit.He is not able to regulate the flow of the coolant and work in intermediate positions. The device is characterized by two operating positions - "open" and "closed", and attempts by the owners to leave the crane in an intermediate position will lead to the device losing its functionality and failing. This type of fittings is quite common in heating systems, so you can buy a tap at any specialized store. It has a fairly simple design, consisting of a durable stainless steel body, a stem and a dense rubber gasket. The appearance of the tap is aesthetically pleasing, so the device can be connected to the circuit without damaging the interior of the room. Such a tap is opened with pliers or a gas wrench, while it should be remembered that over time, the rubber gasket of the tap may lose its elasticity and it will be impossible to flush the batteries with this device. In this case, the owner will have to completely freeze the operation of the circuit and turn off the heating risers. A functional balancing valve in the heating system is used to regulate heat transfer. Unlike the cranes listed above, the device has a more complex design. This is a valve that is equipped with a special retainer, shutter indicator, nozzle and measuring diaphragm. It allows you to balance the distribution of heat so that each battery in the circuit receives the required amount of heated coolant.

operating temperature range from -20 to +120 degrees Celsius;
possibility of equipping with additional options (smooth / stepwise flow rate adjustment, drainage system, bypass valve, settings lock, temperature safety device);
easy installation;
accessible process of operation.

If the scheme provides for the installation of a thermal head on a heating radiator, then it is worth choosing an appropriate tap. It allows you to regulate the temperature of the batteries and helps to create an optimal microclimate in the house.
The crane is distinguished by its long service life, reliability and practicality.

It is mounted on the supply of hot coolant, placing the temperature-sensitive element in a special way. This is necessary so that there are no errors in the measurements of the thermal head associated with the ascent of the flow of hot masses from the radiator.

Other variations of valves for heating are available on the market (for example, a three-way valve for heating), so the owner of the house can choose the optimal type of shut-off valves for the circuit. It will help improve the performance of the heating system, make it more rational, practical and efficient.

The owner of a private house with an autonomous heating system has the ability to turn off the boiler at any time, in accordance with the weather outside or guided by other considerations.

Ball valves are required to shut off the heater

Those who live in houses with central heating, questions about how to turn off the heating battery usually arise in two cases:

if the weather is warm outside, and the central heating has not yet been turned off, since the heating season is not officially over;
if necessary, replace, repair or paint the radiator, repair the wall behind the battery.

In this case, one should take into account the following moment: a coolant is constantly inside the battery. It is drained only in case of repair work in the system. This is due to the fact that the bulk of the heating devices installed in old houses, as well as internal wiring, are made of steel.

The liquid inside the radiator contains a certain amount of oxygen in dissolved form, which over time completely reacts with the metal, as a result of which corrosion stops.

Do not leave the system or a separate heating device empty for a long time - moisture remains on the inner surface of the steel or cast-iron battery, which does not evaporate in a confined space for a long time, which significantly accelerates the corrosion process. Thus, the coolant is drained only in exceptional cases.

In principle, most of the inhabitants of city apartments do not switch off the batteries at the end of the heating season.

This happens for various reasons:

there is no possibility (below it will be described what conditions are needed for this operation);
do not see the need for it.

Why is it worth shutting off the water in the battery, especially if you have installed a new modern radiator? The fact is that at the end at the beginning of the heating season, as well as during test tests in preparing the system for a new winter, a coolant is pumped through the entire network under increased pressure. This means that it is clogged with mechanical impurities - particles of deposits that have had time to build up in old pipelines.

Do not forget to disconnect the device from the water supply after the heating season before the next one - this will keep it as new and reliable.

When contaminated liquid passes through the radiator, there is a risk of its clogging, and this will become clear only at the beginning of the heating season, when it will not be able to work at full capacity. It may need to be dismantled and cleaned. To avoid such problems, it is worth turning off the supply of coolant to the heating batteries.

If it is hot in the apartment or you need to disconnect the radiator without calling a plumber to shut off the entire heating pipe in the entrance, it is important that:

There was a vertical jumper between the supply pipe and the return pipe - a bypass, it is through it that the coolant flow will pass without getting into the installed battery after you close it. The absence of a bypass automatically means that you are shutting off the flow for the entire riser.
Ball valves with American women should be installed on the supply and return pipes between the bypass and the heating radiator. It is they who make it possible to disconnect.
Ideally, an air valve is installed at the radiator inlet.

Attention! Ball valves cannot be used to regulate the flow of the coolant if you want to reduce the heating of the batteries! This valve is a shut-off valve, its use for other purposes leads to the destruction of the valve and leaks.

Based on the foregoing, if there is no bypass, but ball valves are installed, the battery can be independently dismantled for repair or replacement, but not during the heating season.

Heater with installed bypass

The bypass (jumper) is mounted parallel to the radiator and is usually a pipe, the diameter of which is equal to the diameter of the supply pipes or one step less. If you plan to shut off the batteries after the heating season or install a radiator with a thermostat, be sure to take care of installing a bypass. Otherwise, by your actions, you will lower the temperature of the coolant and the neighbors.

Let's imagine that you turned off both taps while the coolant in the system is still hot.

Knowing the elementary laws of physics, one can easily understand that

When the water in the battery cools down, its volume will decrease;
This will lead to the formation of a vacuum in the enclosed space of the radiator;
As a result of the generated pressure, the battery is deformed or loses its tightness, it will need to be replaced.

So, in search of an answer to the question of how to turn off the battery, if it gets hot in the apartment, you already know that this should never be done by closing both taps! Now it remains to figure out whether it is worth using both taps after the heating season, when the coolant has already cooled down.

As we already know, the central heating system is full all year round.In some areas, the coolant is drained if repair work is required, and then refilled. Thus, there is liquid inside your radiator.

If you turn off both the upper and lower valves, the following occurs

Various chemical processes take place in the liquid inside the battery, since the coolant cannot be chemically pure;
As a result of these processes, gas formation occurs;
Since the gases have no possibility of escape, the radiator can be depressurized due to the increased pressure.

Thus, if an air vent (Mayevsky valve) is not installed on the battery, it is categorically not recommended to shut off both stopcocks, even if the coolant temperature is room temperature.

The answer to the question of how to turn off the heating battery is extremely simple - it is enough to close one tap, leaving the second open. But which tap should you turn off?

As we understand it, water is supplied to the heating riser from the bottom.

The upper valve is closed and the lower one is open. If repair work is carried out at neighbors below or in the basement, or on a branch supplying the house, the coolant will be drained and your radiator will be empty. If it is steel or cast iron, it will provoke corrosion.
The lower valve is closed and the upper one is open. Regardless of any repairs, the radiator will be full.

So, we learned how to shut off the battery for the summer season: to do this, close only the lower ball valve.

In case of cold weather, follow the announcements at the entrance about the beginning of the heating season. Then close both ball valves so that debris does not get into the radiator - let it all go through the bypass. In this case, a battery rupture with closed taps does not threaten you - in one or two days, sufficient pressure cannot form inside the radiator. During this time, the apartment will also not have time to freeze, especially since the room will be slightly heated from the riser.

How to turn on the radiator? This is not difficult - just open both ball valves, and the coolant will begin normal circulation through the included radiator.

On the first day of turning on the heating, when you hear the murmur of water in the system, do not rush to open the ball valves. The next day, you can open them using the Mayevsky cock for air release. Attention! If you live on the upper floor, an air vent must be installed on the radiator. This will avoid the formation of air pockets, due to which the heating device does not perform its functions.

Knowing how to close the heating battery, you can decide how to prepare for the new heating season in the summer.

The work of installing the bypass and ball valves should be done by professionals with the involvement of a plumber who will shut off the water in the riser. Note that welding and related equipment will be required.

Emergency replacement of the heating battery

Ball valves and bypass are an opportunity

ensure the safety of their batteries from corrosion and pollution;
do not suffer from heat during sudden warming during the heating period;
ensure safety in the event of an emergency - if the radiator fails, it can be disconnected from the system, while the neighbors will not suffer either from a flood or from a lack of heat;
at any convenient time, independently replace the old radiator with a new one;
remove batteries for flushing or painting.
successfully use modern radiators with a thermostat without disturbing your neighbors.

A competent approach to the organization of apartment heating is a concern for comfort and safety.

How to properly shut off the radiator?

Repair work, heat in the apartment, replacement of the radiator - all this requires disconnecting the batteries. In this article we will tell you how to properly shut off the radiator.

If you need to shut off the heating battery for the summer or turn it off because of the heat, this is easy to do if there are shut-off valves on the heating battery - ball valves. Turn the handle of the valves on the inlet and outlet pipes all the way. This will block the flow of the coolant.

In the photo, the taps are open. In the closed state, the valves of the valves are located perpendicular to the pipe.

Often there is a special adjustment valve on the inlet pipe. It can also be used to shut off the pipe. However, its main function is to maintain a certain temperature regime in the room.

Overlapping the radiator without dismantling it is carried out in the following cases:

Battery painting is required (during the heating season).
Battery flush required.
Replace gaskets and nipples.
It is necessary to shut off the heating battery for the summer.

It is optimal to carry out work related to the removal of the radiator after the end of the heating season. If work needs to be done during the heating season, a number of nuances must be taken into account. If you have a one-pipe heating system and vertical wiring, you can remove the battery only if there is a bypass.

Such a system can be identified by pipes, one of which goes from the ceiling and connects to the radiator, while the other comes out of the radiator and disappears into the floor. The bypass is a jumper that connects the inlet and outlet pipes. This pipe is about the same or slightly smaller diameter than the main pipes. The principle of operation of the bypass is as follows: if the radiator is turned off, water begins to flow along the riser, passing through the bypass, without passing through the battery. In this case, the riser works, the heating in the neighboring apartments is not turned off.

If the system is two-pipe, if there are taps, it is enough to close them, after which the battery can be removed.

The battery is filled with liquid throughout the year. The water is drained only for a short time in the process of centralized repair work. Therefore, if you plan to replace the battery, simply turning it off is not enough - you need to drain the water. Why is the system constantly filled with coolant? It is highly undesirable for oxygen to enter the heating system. When the water is drained, air with water vapor takes its place. This leads to active oxidation - that is, the appearance of rust on the surface of steel and bimetallic batteries. Oxygen dissolved in the coolant does not destroy the metal, i.e. does not lead to corrosion. Therefore, in order for the heating system to serve for a long time, it is always full.

Using a heat shield

The heat from the hot battery is transferred in different directions and directions, creating a comfortable atmosphere in the apartment. The use of a special heat shield will allow not only to effectively reduce the excessive temperature of the battery, but also to avoid heat leakage, reaching up to 20 percent. A battery placed in a niche gives off heat not only to the apartment, but also to the outer wall, actually heating the street.

The device of the heat shield can be carried out using a special heat-insulating material placed between the wall and the heating radiator.

Such a "life hack" will give the heating system several extremely positive qualities:

providing thermal insulation of walls;
prevention of excessive heat transfer arising from differences in outdoor and room temperatures;
providing an effect in which the heat from the heating device is reflected into the depth of the room;
achieving uniform distribution of heat transfer, protection against overheating of the battery.

Various thermal insulation materials used to create screens have a foil backing. A special combination of materials such as polystyrene or foamed polyethylene with foil can shield thermal energy by virtue of its good thermal insulation properties.The foil present in this device reflects about 90 percent of the heat, eliminates its loss and helps it evenly distribute throughout the room.

Heat shield materials

Foil-clad styrofoam is typically found in retail stores as short rolls. The thickness of the material layer in this case is up to 3 millimeters, and for foamed polyethylene - up to 4 millimeters. The thermal insulation properties of these materials are comparable to the properties of a 100 mm layer of mineral wool insulation.

When placing a screen that reflects heat, it is possible and necessary to take into account such an important factor as the minimum distance between the edge of the radiator section of the battery and the inner wall, which is 4 mm. If you change this distance to a smaller side, it will impede or disrupt the circulation of warm air and, as a result, the convection of heat transfer and the efficiency of the radiator.

Particular cases of placing the heating battery on the wall do not allow the installation of a full-fledged screen that reflects heat. A way out of this situation would be to mount aluminum foil on the wall, with its shiny surface perfectly coping with heat reflection. One sheet of such material, placed on a standard brick wall (if its thickness is 51 centimeters), will reduce the heat transfer loss of the battery by up to 35 percent.

The various ways to eliminate excess thermal energy from the battery discussed above can be noted as effective methods that have been proven in practice. If it gets too hot in the apartment, use the voiced one to make it as comfortable as possible in your home.
