How to regulate radiators. Self-regulation of the heating system: review of devices and techniques How to properly regulate heating by flow or return

In apartments or private houses, residents often encounter the phenomenon uneven heating of radiators heating in different parts of the home. Such situations are typical in cases where the premises are connected to autonomous heating systems.

How optimize the system heating (CO), stop overpaying and how installing a heat regulator for batteries will help - we’ll look at it further.

Why do you need heat regulation in an apartment?

For what reasons do citizens more often adjust the heat in their residential premises:

1. Arises the need to create the most comfortable conditions in the house for life.
2. Should get rid of excess air in batteries, achieve efficient heat transfer into interior spaces.
3. Timely installation of regulators allows refrain from frequent ventilation when the air overheats using open windows.
4. Properly selected heating regulators and their proper use will allow reduce the amount of payments for this service by a quarter.

Important! Manipulations to install the CO regulator should be carried out before the beginning heating season. In the midst of frost, such a procedure will require shutting off not only the heating in own apartment, but also in neighboring ones, which will create certain inconveniences.

Setting the return and supply temperatures in an apartment building

Regulator installation heating system will depend on its general structure. If the CO is installed individually for a specific room, the improvement process takes place due to the following factors:

• system works from an individual boiler;
• installed special three-way valve;
• coolant pumping is happening forcibly.

In general, for all COs, power adjustment work will consist of installing a special valve on the battery itself.

With its help you can not only adjust heat level in the right premises, but also eliminate the heating process altogether in areas that are poorly used or do not function.

Exist the following nuances When adjusting the heat level:

1. Systems central heating, which are installed in multi-storey buildings, are often based on coolants, where feeding occurs strictly vertically from top to bottom. In such houses, it is hot on the upper floors and cold on the lower floors, so it will not be possible to adjust the heating level accordingly.
2. If used in homes single-pipe network, then heat from the central riser is supplied to each battery and returned back, which ensures uniform heat on all floors of the building. In such cases, it is easier to install heat control valves - installation takes place on the supply pipe and the heat continues to spread evenly.
3. For two pipe system There are already two risers installed - heat is supplied to the radiator and in the opposite direction, accordingly the adjustment valve can be install in two places - on each of the batteries.

Types of Battery Control Valves

Modern technologies are far from standing still and make it possible to install for each heating radiator high quality and reliable crane, which will control the heat and heating levels. It connects to the battery special pipes, which will not take much time.

By type of adjustment I distinguish two types of valves:

1. Conventional thermostats with direct action. Installed next to the radiator, it is a small cylinder, inside of which the siphon based on liquid or gas, which quickly and competently responds to any temperature changes. If the temperature of the battery rises, the liquid or gas in such a valve expands, causing pressure to valve stem heat regulator, which will move and block the flow. Accordingly, if the temperature drops, the process will be reversed.

1. Thermostats based on electronic sensors. The principle of operation is similar to conventional regulators, only the settings differ - everything can be done not manually, but electronically - set the functions in advance, with a possible time delay and temperature control.

How to adjust heating radiators

Standard process for regulating the temperature of heating radiators consists of four stages— bleeding air, adjusting pressure, opening valves and pumping coolant.

1. Bleeding air. Each radiator has special valve, by opening which you can release excess air and steam that interferes with the heating of the battery. Within half an hour after such a procedure, the required heating temperature must be achieved.
2. Pressure adjustment. To distribute the pressure in the CO evenly, you can turn shut-off valves different batteries attached to one heating boiler for different numbers of revolutions. This adjustment of the radiators will allow you to heat the room as quickly as possible.
3. Opening valves. Installation of special three way valves on radiators will allow you to remove heat in unused rooms or limit heating, for example, while you are away from the apartment during the day. It is enough to simply close the valve completely or partially.

Photo 2. Three-way valve with thermostat, allowing you to easily adjust the temperature of the heating radiator.

1. Coolant pumping. If the CO is forced, the coolant is pumped using control valves, with the help of which a certain amount of water is drained to give the heating radiator the opportunity to heat up.

Adjusting heating in a private house

In private homes, it is necessary to pay attention to heating systems even at the time of design, you should choose a high-quality boiler or other heating equipment.

You can regulate the heating in your home using special technical devices two types:

• regulating— installed both in individual sections of the network and for the entire CO, they help control and regulate the pressure level in the system, increase or decrease it;
• controlling- various sensors and thermometers, with the help of which information is obtained about the pressure level and other parameters of the heating system and there is the possibility of adjusting them in one direction or another.

To timely monitor the operation of the CO in the house, you need provide for the installation of pressure gauges and thermometers in areas before and after the heating boiler, at the lower and upper points of the heating system, installation expansion tank, safety valves, air vents. If the heating system is working correctly, the water in it should not heat above 90 °C, and the pressure will not exceed 1.5-3 atmospheres.

A common situation is that one radiator is hotter than the other, which should not be the case. Or it’s cool in one part of the house and hot in another. This means that the heating system needs to be somehow adjusted, as experts say – balanced. It is possible that for this you do not need to call a plumber at all, and you can adjust the heating yourself.

To do this, control taps and/or balancing valves must be installed on each radiator or between the arms of the system.

But in some cases the system needs to be redone. Read more about possible heating problems and balancing rules below.

If there is not enough radiator power

It also happens that it is difficult to balance the heating system, since the distribution of radiator power does not at all correspond to the heat loss of the rooms.

Recommendations for the selection of radiators are as follows: for 10 sq. m. area - 1 kW, but this value is multiplied by 1.2 if the room has one window, 1.3 if the window is large, 1.4 if there are two windows and the room is corner, 1.5 if there are already 3 windows or a large glazing area.

In addition, the radiator power is indicated for a temperature of 90 degrees, but we are going to heat it at a maximum of 70 degrees, aren’t we? This means we multiply the heat loss by another 1.3. And if low-temperature heating is used - no more than 50 degrees, then multiply by 1.3 again.
Why is low-temperature heating the most comfortable and economical?

The power of one section of an aluminum, bimetallic radiator (approximately 80 mm thick and wide), or cast iron radiator (old MS-140 type) is approximately 170 - 180 W. A set of 7 sections is considered to be no less than a kilowatt.

In addition, radiators must be installed in characteristic locations to create thermal curtain source of cold. Typically - under the windows, near the door.

It is better to distribute the number of battery sections (sizes) in accordance with heat loss and the characteristics of the heating system than to balance and cover the flow of liquid.

Simple causes of heating system problems

It is possible that there is air in the heating system and for this reason the coolant does not flow well to one or more heating devices.

In the highest places in the pipeline, air valves (Mayevsky valves) are installed that can be opened manually. Or automatic air vents. Mayevsky taps are usually installed on each radiator. Walk through the system, open the taps, bleed the air.

Another reason bad work– clogging, first of all, of the filter element. Unscrew the filter and clean it.
Before any balancing of the heating system, clean the filter.

In improperly assembled systems, in addition, there may be clogging at the lower points at differences in the pipeline level, and airing at the upper points, for example, the pipeline is wrapped around a door without an air vent.

Balancing the system using valve regulators

It is possible that the very design of the system requires balancing. For example, one long arm is used and the other is short.

Or the arm length of the dead-end pattern is too long. Or a beam scheme is used, which requires initial configuration. And it happens that they make archaic one-pipe systems with shortcomings. In either case, the result is significant uneven heating.

So, balancing valves are installed on the radiators; all that remains is to ensure that the temperature of all radiators is approximately the same.

The principle of balancing is the simplest - do not close (open as much as possible) the taps on the coldest ones and “tighten” the hottest ones a little. As a result, more coolant will flow to the cold ones, less to the hot ones, and their temperature will equalize.

An example of how to adjust heating in a one-story house

A typical example is that it was not possible to make two arms of a dead-end circuit, since the pipes were being laid in the way of a door, so they made one arm and put “as many” 7 radiators on it.

As a result, the temperature of the latter in the shoulder is 9 degrees less than that closest to the boiler. You can do the following: on the last 3 radiators, leave the taps completely open. On the first, open the balancing valve from the fully closed position by 1.5 turns, on the second - by 2 turns, on 3 and 4 by 2.5 turns.

It is implied that the total balancing valve adjustable by 4.5 turns, and the length of the pipelines is within small house. But there are regulators different designs, the lengths are different, so in each case there is a different number of turns.

After balancing, you need to wait 20 minutes, then measure the temperature of the incoming radiator pipe again, you may have to additionally adjust something by a quarter turn...

Adjustment principles

Significant closures cannot be created.
The basic principle of balancing is to open the path for coolant movement as much as possible. Closure is a forced measure.

Therefore, achieve in in this example the same temperature is not worth it. It is correct to agree that the first one will be hotter by 3 - 4 degrees at a coolant temperature of 80 degrees and by a couple of degrees with low-temperature heating of 50 degrees.

How to measure it? Professionals would look at each radiator through a thermal imager and take a thermal photo. But you can get by with contact thermometers - special devices for heater installers. But in everyday life, they often measure simply with their hands and judge by how they feel. The earlobe is sensitive in this regard - but is it worth rubbing your ear on the radiators...

Example for a two-story house

More typical example, when the designers and installers managed to design the heating system in such a way that they installed approximately equal power radiators on both the first and second floors (the areas are approximately equal), and they forgot to solder the balancing of the floors relative to each other.

As a result, it is still cold on the first floor, but it is already hot on the second floor.

Again, balancers installed directly on the radiators will help out. On the second floor we simply turn off the taps by 2 turns instead of the full 4.5, thus reducing the fluid flow by 30 percent. By reducing the energy output, we equalize temperature regime, if necessary, we close more...

Commissioning according to the project

With normal proper installation modern system For heating, balancing is not needed at all; the circuit is designed in such a way that all radiators heat optimally. In addition, they are often automated with thermal heads, with which you can set the temperature in a separate room.

Designers and design data introduce a little confusion into the issues of heating adjustment. The project includes the amount of coolant passing through and the balancing of each radiator - how many revolutions each balancing valve of a certain type should be turned.

This achieves a certain accuracy in the implementation of design decisions. But for the user this practically does not matter, since adherence to design accuracy has very little effect on the final result. A large values balancing (as in the examples above) cannot be included in the project. Therefore, very precise regulation according to the design can be ignored.

Noisy radiator

Another point that needs to be addressed is that a large number of coolant passing through the radiator. At the same time, the radiator makes noise and this is unpleasant. Reasons: incorrect heating scheme, unbalanced (closed) other radiators, too powerful pump in the system. All this needs to be eliminated.

An overly powerful pump is a problem with homemade heating systems, because home craftsmen “seem” that they can’t spoil the porridge with oil. But what happens here is something else - a lot of money wasted and noise in the radiators.
A noisy radiator requires balancing the system or reworking it.

System diagram with regulators

Each heating season brings its own surprises with difficulties in heating rooms, both for residents of multi-storey buildings and private cottages. The quality of uniform heating of all rooms of the house depends on how the temperature of the heating radiators is adjusted.

Why do you need to make adjustments?

Settings optimal temperature heating batteries allows you to create maximum indoor comfortable conditions stay. In addition, adjustment allows:

1. Remove the effect of air in the batteries, allow the coolant to move freely through the pipeline of the heating system, effectively giving off its heat internal space premises.
2. Reduce heat consumption costs by up to 25%.
3. Don't hold it all the time open windows, with excessive overheating of the air in the room.

It is advisable to set up heating and adjust batteries before the start of the heating season. This is necessary so that later you do not experience discomfort in the apartment and do not adjust the heating temperature of the batteries in emergency mode. Before setting up and adjusting the radiators, initially in the summer you need to thermally insulate all windows. In addition, you need to take into account the specific location of the apartment:

• In the middle or corner of the house.
• Lower or upper floor.

After analyzing the situation, it is advisable to use energy-saving technologies to maximize heat conservation inside the apartment:

• Insulate walls, corners, floors.
• Carry out hydro and thermal insulation of the seams between the concrete joints of the panel house.

Without this work, it will be useless to regulate the temperature of the radiators, since the lion's share of the heat will heat the street.

Types of heating systems and the principle of adjusting radiators

To correctly adjust the temperature of radiators, you need to know general device heating systems and coolant pipe distribution.

• When individual heating, adjustment is easier when:

1. The system is powered by a powerful boiler.
2. Each battery is equipped with a three-way valve.
3. Forced pumping of coolant has been installed.

At the stage installation work For individual heating, it is necessary to take into account the minimum number of bends in the system. This is necessary in order to reduce heat loss and not reduce the pressure of the coolant supplied to the radiators.

For even heating and rational use heat, a valve is mounted on each battery. With it you can reduce the water supply or turn it off common system heating in an unused room.

• In the central heating system of multi-storey buildings, equipped with a vertical supply of coolant through a pipeline from top to bottom, it is impossible to adjust the radiators. In this situation, the upper floors open the windows due to the heat, and the rooms on the lower floors are cold, since the radiators there are barely warm.
• A more advanced one-pipe network. Here the coolant is supplied to each battery and then returned to central riser. Therefore, there is no noticeable temperature difference in the apartments on the upper and lower floors of these buildings. In this case, the supply pipe of each radiator is equipped with a control valve.
• A two-pipe system, where two risers are mounted, ensures the supply of coolant to the heating radiator and back. To increase or decrease the coolant flow, each battery is equipped with a separate valve with a manual or automatic thermostat.

Types of control valves

Existing modern technologies heating systems make it possible to install a special tap on each radiator that controls the quality of heat. This control valve is a heat exchanger of shut-off valves, which is connected via pipes to a heating radiator.

According to the principle of their operation, these cranes are:

• Ball, which serve primarily as 100% protection against emergency situations. These shut-off devices are a structure that can be rotated 90 degrees and can allow water to pass through or prevent the passage of coolant.

The ball valve must not be left in a half-open state, as this may cause damage. sealing ring and a leak will form.

• Standard, where there is no temperature scale. They are represented by traditional budget valves. They do not provide absolute accuracy of adjustment. By partially blocking the access of coolant to the radiator, they change the temperature in the apartment to an indefinite value.
• With a thermal head that allows you to adjust and control the parameters of the heating system. Such thermostats are automatic and mechanical.

Conventional direct-acting thermostat

Thermostat direct action is a simple device for monitoring the temperature in a heating radiator, which is installed near it. By its design, it is a sealed cylinder into which a siphon is inserted with a special liquid or gas that clearly reacts to changes in the temperature of the coolant.

As it increases, the liquid or gas expands. This leads to increased pressure on the rod in the thermostat valve. It, in turn, moving, blocks the flow of coolant. When the radiator cools, the reverse process occurs.

Thermostat with electronic sensor

This device is no different in operating principle from the previous version, the only difference is in the settings. If in a conventional thermostat they are performed manually, then an electronic sensor does not need this.

Here the temperature is set in advance, and the sensor monitors its maintenance within the specified limits. The electronic thermostatic sensor regulates the control parameters of the air temperature within the range from 6 to 26 degrees.

Step-by-step instructions for adjusting temperature

To ensure comfortable living conditions in the room, you need to perform some basic steps.

1. Initially, it is necessary to bleed the air on each battery until water flows from the tap in a trickle.
2. Then you need to adjust the pressure in the batteries.
3. To do this, in the first battery from the boiler you need to open the valve by two turns, on the second - by three, and then according to the same scheme, increasing the number of turns of the valve being opened on each radiator. Thus, the coolant pressure will be evenly distributed over all radiators. This will ensure its normal passage through the pipes and better heating of the batteries.
4. IN forced system heating, pumping coolant, monitoring rational heat consumption will help to implement control valves.
5. In a flow-through system, the temperature is well regulated by thermostats built into each battery.
6. In a two-pipe heating system, you can control not only the temperature of the coolant, but also its quantity in the batteries using both manual and automatic systems management.

What causes the pressure difference in heating and water supply systems? What is it for? How to regulate the difference? For what reasons does the pressure drop in the heating system? In this article we will try to answer these questions.

Functions

First, let's find out why the difference is created. His main function– ensuring coolant circulation. Water will always move from a point with more pressure to a point with less pressure. How more difference- the higher the speed.

Useful: the limiting factor is the hydraulic resistance that increases with increasing flow velocity.

In addition, a difference is artificially created between the circulation connections of hot water supply into one thread (supply or return).

Circulation in in this case performs two functions:

1. Provides consistently high temperature heated towel rails, which are in all modern houses open one of the hot water supply risers connected in pairs.
2. Guarantees fast delivery hot water to the mixer regardless of the time of day and water supply through the riser. In old houses without circulation taps, the water has to be drained for a long time in the morning before it is heated.

Finally, the difference is created by modern water and heat consumption meters.

How and why? To answer this question, the reader must be referred to Bernoulli's law, according to which the static pressure of a flow is inversely proportional to the speed of its movement.

This gives us the opportunity to design a device that records water flow without the use of unreliable impellers:

• We pass the flow through the section transition.
• We record the pressure in the narrow part of the meter and in the main pipe.

Knowing the pressures and diameters, using electronics it is possible to calculate in real time the flow rate and water consumption; when using temperature sensors at the inlet and outlet of the heating circuit, it is easy to calculate the amount of heat remaining in the heating system. At the same time, the consumption of hot water is calculated based on the difference in flow rates in the supply and return pipelines.

Creating a drop

How is pressure difference created?

Elevator

The main element of the heating system apartment building– elevator unit. Its heart is the elevator itself - a nondescript cast-iron tube with three flanges and a nozzle inside. Before explaining the principle of operation of the elevator, it is worth mentioning one of the problems of central heating.

There is such a thing as a temperature graph - a table of the dependence of the temperatures of the supply and return routes on weather conditions. Let's give a short excerpt from it.

Deviations from the schedule up and down are equally undesirable. In the first case, it will be cold in the apartments, in the second, energy costs at the thermal power plant or boiler house will increase sharply.

At the same time, as is easy to see, the spread between the supply and return pipelines is quite large. With circulation slow enough for such a temperature delta, the temperature heating devices will be unevenly distributed. Residents of apartments whose radiators are connected to the supply risers will suffer from the heat, and owners of return radiators will freeze.

The elevator provides partial recirculation of the coolant from the return pipeline. By injecting a fast stream of hot water through the nozzle, in full compliance with Bernoulli's law, it creates a fast flow with low static pressure, which draws additional mass of water through the suction.

The temperature of the mixture is noticeably lower than that of the supply and slightly higher than that of the return pipeline. The circulation speed is high, and the temperature difference between the batteries is minimal.

Support washer

This simple device is a steel disk at least a millimeter thick with a hole drilled in it. It is placed on the flange of the elevator unit between the circulation taps. Washers are placed on both the supply and return pipelines.

Important: for normal operation elevator unit, the diameter of the holes in the retaining washers must be larger than the diameter of the nozzle.
Usually the difference is 1-2 millimeters.

Circulation pump

IN autonomous systems heating pressure is created by one or more (according to the number of independent circuits) circulation pumps. The most common devices are with wet rotor– are a design with a common shaft for the impeller and electric motor rotor. The coolant performs the functions of cooling and lubrication of bearings.

Values

What is the pressure difference between different sections of the heating system?

• Between the supply and return lines of the heating main it is approximately 20 - 30 meters, or 2 - 3 kgf/cm2.

Reference: overpressure in one atmosphere the water column rises to a height of 10 meters.

• The difference between the mixture after the elevator and the return pipeline is only 2 meters, or 0.2 kgf/cm2.
• The difference on the retaining washer between the circulation taps of the elevator unit rarely exceeds 1 meter.
• Pressure created circulation pump with a wet rotor, usually varies from 2 to 6 meters (0.2 - 0.6 kgf/cm2).

Adjustment

How to adjust the pressure in the elevator unit?

Support washer

To be precise, in the case of a retaining washer, it is not necessary to adjust the pressure, but to periodically replace the washer with a similar one due to abrasive wear of a thin steel sheet in technical water. How to replace the washer with your own hands?

The instructions are generally quite simple:

1. All gates or valves in the elevator are closed.
2. One drain valve is opened on the return and supply to drain the unit.
3. The bolts on the flange are loosened.
4. Instead of the old washer, a new one is installed, equipped with a pair of gaskets - one on each side.

Tip: in the absence of paronite, washers are cut from an old car inner tube.
Don't forget to cut an eyelet that will allow the washer to fit into the flange groove.

1. The bolts are tightened in pairs, crosswise. After the gaskets are pressed, the nuts are tightened until they stop, no more than half a turn at a time. If you rush, uneven compression will sooner or later lead to the gasket being torn out by the pressure on one side of the flange.

Heating system

The difference between the mixture and the return flow is normally regulated only by replacing, welding or drilling out the nozzle. However, sometimes it becomes necessary to remove the difference without stopping the heating (usually in case of serious deviations from temperature chart during the peak of cold weather).

This is done by adjusting the inlet valve on the return pipeline; Thus, we remove the difference between the forward and reverse threads and, accordingly, between the mixture and the return.

1. We measure the supply pressure after the inlet valve.
2. Switch the hot water supply to the supply thread.
3. We screw the pressure gauge into the vent on the return line.
4. We completely close the input check valve and then gradually open it until the difference decreases from the original by 0.2 kgf/cm2. Manipulation with the closing and subsequent opening of the valve is necessary to ensure that its cheeks are lowered as much as possible on the stem. If you simply close the valve, the cheeks may sag in the future; the price of ridiculous time savings is at least defrosted access heating.
5. The return pipe temperature is monitored at daily intervals. If it is necessary to further reduce it, the difference is removed 0.2 atmospheres at a time.

Pressure in the autonomous circuit

The immediate meaning of the word “difference” is a change in level, a fall. In the article we will touch on it too. So, why does the pressure drop in the heating system if it is a closed loop?

First, let's remember: water is practically incompressible.

Excessive pressure in the circuit is created due to two factors:

• The presence in the system of a membrane expansion tank with its air cushion.

• Elasticity. Their elasticity tends to zero, but with a significant area of ​​the inner surface of the circuit, this factor also affects the internal pressure.

WITH practical side this means that the pressure drop in the heating system recorded by the pressure gauge is usually caused by an extremely slight change in the volume of the circuit or a decrease in the amount of coolant.

Here's a possible list of both:

• When heated, polypropylene expands more than water. When starting a heating system assembled from polypropylene, the pressure in it may drop slightly.
• Many materials (including aluminum) are sufficiently plastic to change shape under prolonged exposure to moderate pressure. Aluminum radiators can simply swell over time.
• Gases dissolved in water gradually leave the circuit through the air vent, affecting the actual volume of water in it.
• Significant heating of the coolant when set too low can trigger the safety valve.

  In the photo there is an intersectional leak on cast iron radiator. Often it can only be noticed by traces of rust.

  Conclusion

  We hope that we were able to answer the reader’s questions. The video attached to the article, as usual, will offer additional thematic materials to his attention. Good luck!

This page is dedicated to such an important topic as adjusting heating radiators in an apartment: how to adjust the system in apartment building, how to set up a radiator using a Mayevsky tap, methods for regulating heat supply.

More and more residents of apartment buildings are thinking about how to regulate heating radiators in an apartment.

This is due both to the desire to save heat in order to reduce payments for it, and to the ability to control its quality.

As life shows in its examples, often the heating season and cold weather come suddenly, when the services in charge of heat are not ready for them.

Temperature standards in the room

Surely, every resident would like to have a heating regulator in the apartment in an apartment building in order to use it to create comfortable living conditions for themselves in winter period. In fact, not everyone knows what it is and why adjusting the heating in an apartment is needed.

In fact, it allows you to:

1. The wearer can move freely through the heating circuit pipes, avoiding airiness. This allows it to fully transfer heat to the room, creating a pleasant microclimate.
2. Makes it possible to reduce costs by up to 20-25%, reducing the heating of radiators. As practice shows, lowering indoor air heating by just 1 degree results in savings of up to 6%.
3. Adjusting the temperature of the heating battery in the apartment allows you to increase the heat supply, if it is not enough.

Any work on adjusting or setting up the heating system is best done before the start of the heating season.

To determine how much to raise or lower the temperature in the system, you need to know what is considered normal. If you turn to SNiP, it says that for corner rooms it is +20-22, and for the rest - +18 degrees.

Based on these data, the consumer knows that adjusting the temperature of the heating radiators in the apartment helped him save money if he cooled it himself, or vice versa.

Unfortunately, not all residential buildings can be equipped with heat regulators:

1. If in multi-storey building vertical top piping, then installation of control valves is impossible. This means that the supply of coolant starts from the upper floors, so in any frost there, “Africa” and residents are forced to open the windows, while on the lower floors the radiators are lukewarm.
2. If there is a single-pipe system in the building, there is no such problem, since the carrier, having passed through all the batteries, returns back to the central riser. This allows heat to be evenly distributed throughout all rooms, regardless of their number of floors, and control valves are installed on the supply pipe of all heating radiators.
3. The two-pipe system, although considered somewhat more expensive, is nevertheless the best in both heat supply and heat regulation. It has separate pipes for supplying the media and returning it to the system. In this scheme, adjustment of the heating radiator in the apartment is carried out separately in each room, since they are all equipped with special valves or automatic devices.

As practice shows, those who have heat supply regulators in their apartments can be called lucky. This allows them to create comfortable living conditions for themselves and optimize costs.

Heat control methods

The main task of regulation is to achieve a certain heating of the air in the room.

This can be done using the following methods:

1. Quantitative is a method in which the rate of coolant supply to the system is changed using a locking mechanism or circulation pump. The amount of carrier decreases as it slows down, and much less of it passes per unit of time.
2. If you change the quality of the media by affecting its heating, you get qualitative method heating system adjustments.

If high-quality equipment is installed in an apartment building, then these 2 methods are carried out simultaneously.

Adjusting the heating in an apartment building using the first method is considered simple if it is done using a circulation pump. When it gets cold, it “drives” the coolant through the system at high speed. It gets hot, its work slows down, and the medium flows at a minimal pace.

Such mechanisms are equipped with automatic equipment that allows you to set a saving mode, for example, at night or when no one is in the apartment.

U this method there is a drawback. The temperature drops equally in all rooms, which is not entirely acceptable, for example, for a children's room or bath.

The best option for regulating heating is the one where each radiator is individually equipped with a special device. This is how you can install comfortable temperature in any room, for example, lowering it in the kitchen, where hot radiators are not needed, or raising it in the bedroom.

Types of control devices

The ability to truly influence the air temperature in the room depends largely on the quality of these devices.

There are several types of control valves for heating an apartment building:

1. How to turn off the heating radiator in an apartment? In fact, control valve- This is the heat exchanger of the shut-off device, which is attached to the radiator. One such device is Ball Valves, the main function of which is to protect the system from emergency situations, and their ability to rotate 90 degrees allows you to block access to the coolant or open its path through the pipes. It would be a stretch to call them regulatory, since their purpose is protection.

   The ball valve must be either open or closed. In a half-baked state, the seal becomes damaged over time and it leaks.

2. Standard valves are budget option control devices, and the benefit from them is the same. Since they do not have a temperature scale, one can only assume how much the conditions in the apartment will change when they are opened or closed.
3. How to regulate heating in an apartment? Adjusting the heating system of an apartment building using device equipped with a thermal head, makes it possible to control the level of heating and cooling of the heating system.

The last type of thermostats comes in two types:

1. Direct acting device, which is based on a siphon with gas or a special liquid that reacts to any temperature changes coolant. If it heats up, the carrier inside the siphon, sealed in the body, will expand and put pressure on a special valve. It, moving under pressure, blocks access to the heating system coolant. When the temperature decreases, the reverse process occurs.
2. A better, but also more expensive option is regulator with electronic sensor . Having given it the necessary parameters, the automation will independently monitor any violations of the parameters in one direction or another.

How to adjust heating in an apartment building? To really know how to set up radiators in an apartment, it is better to purchase a high-quality thermostat, set it with the necessary parameters, and be sure that everything is under its constant control. This device, by regulating the supply of media to the system, will help save on heat costs, thus justifying its profitability.

Adjusting heating radiators in an apartment: increasing heat transfer

It happens that the quality of services provided by management companies is not always at the proper level and people experience discomfort in their homes. In this case, they wonder what to do if the heating in the apartment is weak? The answer may be to find the cause of cold indoors. Either these are defects in the system, or an increase in the heat transfer of the radiators is required.

Batteries are cold for several reasons:

1. The system is airy and the media will need to be drained to remove air from the pipes.
2. Errors were made during connection, for example, due to the bypass remaining in open position, the circulation of the carrier is disrupted.
3. Initially incorrect system calculations, for example, by the quantity and quality of radiators or pipe diameter.
4. Heating systems tend to become clogged over long periods of use., which extremely interferes with the normal movement of the carrier through the pipes, and as a result, the batteries are slightly warm.

Other defects are possible, but it is better to entrust their search to specialists.

If you just need to increase the efficiency of the batteries, this can be done in the following way:

1. If there is not enough thermal power due to incorrect calculations, then it is enough to connect additional sections to the battery to make the room warmer.
2. Sometimes it is worth checking the efficiency of the battery connection. For example, if reverse side was used, this reduces the efficiency of the radiator by 20-25%. If the heating system allows you to change the connection, then, after agreeing with the employees, management company, you need to do this.

Sometimes it happens that residents are dissatisfied with the heat rather than the cold, then they wonder how to turn down the heating in the apartment. This can only be done with the help of a thermostat, but not by shutting off the batteries. As experts note, sometimes the system needs to be balanced so that it works flawlessly, and this can be done with your own hands.

Why is it cold in the apartment?

When it turns out that one part of the system is hot and the other is not, then you should find out how to adjust the heating radiator in the apartment. Sometimes this is easy to do if it has thermostats installed. Otherwise, you will have to seek help from specialists.

Causes of cold batteries:

1. Before the start of the season, the system must be purged by heating network technicians.
2. Operational adjustments are carried out during the heating season in order to see the results of reconfiguring the system. For this purpose, control devices are used.
3. Sometimes it is necessary to change the location of the batteries or their location relative to the floor and windowsill. Incorrectly mounted, they do not allow warm air circulate freely throughout the room, hence the cold.
4. If the heating circuit is outdated, then balancing the heating system in an apartment building will not help, since a complete replacement of radiators and risers is required.

Sometimes a sudden imbalance of batteries and cold in the apartment are caused by the fact that neighbors installed new batteries after removing the thermostats. In this case, the issue can also be resolved by replacing the radiators.

Additional regulation methods

When dissatisfaction with the quality of services from the heating network becomes large, people begin to look for opportunities, ways to regulate the heating system in an apartment building, how to correct the situation, and what to install to make the apartment warm and pay less for it. In this case, errors are possible that can lead to a breakdown of the entire home network.

For example, adjusting the heating system of an apartment building using valves is strictly prohibited.

They belong to the category of shut-off valves, therefore they can operate only in two positions: “open” and “closed”. Residents, not knowing this, try to leave the valves ajar, which disables them.

A weather control system for heating in an apartment building will be useful if a common building meter is installed in it. Only in this case, such a device saves up to 35% of heat consumption. At the heart of the weather heating controller for an apartment building is a sensor that detects temperature changes outside and reacts to them by changing the temperature in the network. Such a device, together with installation, will cost residents of the house more than 500,000 rubles.

Adjusting heating radiators using Mayevsky cranes helps with airiness in the system, which is sometimes enough to make the batteries warm.

Drawing conclusions, we can say that today the question of who regulates the heating temperature in an apartment building is especially relevant. Residents want to participate in this process, and if the heating system allows it, they contact the management office with applications to install thermostats on their radiators.

The choice of devices for this is quite large on the domestic market and their installation does not take much time, but gives tangible results, both in terms of heat quality and its savings. Therefore, it is worth studying the principles of operation of thermostats, applying for its installation, and then enjoying comfortable warmth in his apartment.
