How to open a tap on a heating battery

Although turning on the tap on a heating radiator may seem like a straightforward chore, it’s an essential part of making sure your house is comfortable and efficiently heated. You can control the temperature in various rooms, increase energy efficiency, and avoid potential problems like uneven heating or noisy radiators by knowing how to open a tap on a heating battery correctly. We’ll show you how to properly open a tap on a heating radiator in this guide.

First and foremost, it’s critical to understand the function of the tap on a heating radiator. The hot water flow into the radiator is managed by these taps, which are also referred to as control valves or radiator valves. You can control the amount of hot water that enters the radiator and, consequently, the temperature of the room by adjusting the tap. This straightforward system is essential for preserving a cozy interior environment and maximizing energy efficiency.

It’s useful to find the tap on the radiator before you begin to open it. The inlet valve, located at the bottom of most radiators, and the outlet valve, located at the top, are the two taps. The outlet valve permits water to return to the central heating system, while the inlet valve regulates the flow of hot water into the radiator. Turning the tap clockwise will usually open it, but it’s important to check the exact type of valve you have as some may work differently.

After locating the tap, it’s time to move it to the appropriate location. To raise the temperature in the space, gradually rotate the tap in a clockwise direction until a faint hissing sound, signifying an open valve, is heard. Avoid forcing the tap as much as possible as this can harm the valve or result in leaks. On the other hand, slowly rotate the tap counterclockwise until it stops if you wish to reduce the heat or turn off the radiator entirely.

It’s important to check the room’s temperature after turning on the tap and make any necessary adjustments. Remember that completely opening the tap could cause the radiator to get too hot, and completely closing it would stop any heat from entering the space. A number of variables, including the outside weather, your home’s insulation, and your own comfort preferences, will determine the ideal balance.

To sum up, being able to open the tap on a heating radiator is an easy yet essential skill for keeping your home cozy and energy-efficient. Through comprehension of the tap’s function, placement on the radiator, and precise adjustment, you can efficiently control the temperature in various rooms while maximizing energy efficiency. To guarantee the best possible heating performance throughout your house, always handle the faucets with gentleness and keep an eye on the temperature.

Installation of locking reinforcement in different areas of the circuit

Since different heating cranes may serve distinct purposes, the devices are installed in the areas designated by the project. Generally, the heating scheme provides explicit guidance on what kind of locking reinforcement to add to different kinds of radiators that are attached to the contour.

The heating system’s performance may deteriorate if recommendations are ignored.

Thus, purchasing a heating control valve from the project is preferable for the owner. The shame of radiators and the emergence of cold spots can be avoided with the installation of a crane on the battery to lower the air from the heating system.

Types of heating taps

You must be aware of a few system operating parameters before selecting a heating crane. It will assist in selecting the appropriate working pressure in the circuit, the diameter of the pipelines used to strap batteries, and the preferred installation technique for the device. As previously stated, cranes are installed on the heating battery in line with the heating scheme; however, the choice to install a particular type in the crane contour is made subsequent to the determination of the type of batteries and whereabouts in the circuit.

Right now, the following kinds of cranes are in use:

  1. Maevsky crane;
  2. ball crane;
  3. flushing valve;
  4. Balancing crane;
  5. Thermogram tap.

Maevsky crane

Оогда замена кранов на батареях отопления осуществляется, кран Маевского может использоваться вместо традиционной запорной арматуры. This component is identical to the others in terms of cost and design intricacy, but it makes significant improvements to the system’s functionality by removing air from the contour and preventing cracks in heating batteries. This kind of locking reinforcement lets you quickly lower the air before the system launches for the season or when the radiators are removed.

When purchasing a Mayevsky crane, it is important to consider its details:

  • the device has a small throughput;
  • The crane has a long service life and is resistant to physical wear;
  • There are various cranes designed for a screwdriver and a special key;
  • In some taps, the rod can get out completely and provoke a heat carrier leak from the radiator.

Ball crane

The coolant flow in the pipeline can overlap and open with this kind of locking reinforcement. A perfectly smooth ball that rotates 90 degrees and opens and closes the outline is part of the design of a brass or steel device. It may also contain Teflon bushings that maximize locking valve performance.

  1. simplicity of operation;
  2. affordable cost;
  3. Minimum hydraulic resistance in the open position of the crane.

It should be recognized that the ball crane functions as a circuit-locking device. He is unable to operate in intermediate positions and control the coolant’s heat flow. The two work provisions of the device are "openly" and "closed," and the owners’ attempts to leave the crane in an in-between position will cause the device to malfunction and lose its functionality.

Flushing taps

Since heating systems frequently use this kind of reinforcement, you can buy a crane from any specialty retailer. Its construction is quite straightforward, with a sturdy stainless steel rod, a dense rubber gasket, and stainless steel. Because of the crane’s attractive appearance, the interior of the room won’t be harmed when the device is attached to the contour.

When opening a crane of this type with pliers or a gas key, keep in mind that the rubber covering of the crane may eventually become less elastic, making it impossible to flush the batteries with this tool. In this scenario, the owner will need to disable the heating risers and freeze the contour entirely.

Balancing crane

Heat transfer in the heating system is controlled by a functional balancing crane. The device has a more intricate design than the cranes mentioned above. This valve has a pipe, a measuring aperture, a shutter indication, and a unique lock. It enables you to distribute heat evenly so that the circuit’s batteries all get the necessary quantity of heated coolant.

  • the temperature range of work is from -20 to +120 degrees Celsius;
  • the possibility of equipment with additional options (smooth/stepped consumption setting, drainage system, bypass valve, blocking of settings, temperature fuse);
  • simple installation;
  • Available operation process.

The tap with a thermogol

You should select the appropriate valve if the plan calls for installing a thermal gun on a heating radiator. It helps create the ideal microclimate in the house and lets you change the temperature of the batteries.

The crane stands out for its extended service life, dependability, and usefulness.

It is installed specifically with the thermally sensitive element on the hot coolant supply. This is required to ensure that measurements of thermograms related to the rise in hot mass flow from the radiator are accurate.

The owner of the home can select the best kind of locking reinforcement for the contour from the various heating crane variations that are on the market, such as a three-way tap for heating. It will contribute to the heating system’s improved operation by making it more sensible, useful, and efficient.

Correct disconnection of heating batteries

The owner of a private residence with an autonomous heating system is free to disconnect the boiler whenever the street’s weather warrants it or for other reasons.

In order to prevent the heating device from operating, ball valves must exist.

For those who reside in homes with central heating, there are typically two scenarios in which inquiries about blocking the heating battery come up:

  • If warm weather has been installed on the street, and the central heating has not yet been disconnected, since the officially heating season is not completed;
  • If necessary, replace, repair or paint the radiator, repair the wall behind the battery.

It’s important to remember that coolant is continuously present inside the battery at this point. It is only emptied when system repairs are necessary. This is because the majority of the heating equipment that was installed in the old building’s homes, along with the wiring within each individual home, are composed of steel.

A certain amount of dissolved oxygen is present in the fluid inside the heating battery. This oxygen eventually reacts with the metal completely, stopping corrosion.

A steel or cast-iron battery’s inner surface has moisture that does not evaporate over time in a closed space, making it impossible for the system to remain empty for an extended period of time or for a separate heating device to be fully functional.Corrosion processes are accelerated dramatically by this. As a result, the heat carrier only merges in rare circumstances.

Is it worth it to block the heating devices?

At the end of the heating season, most city apartment residents don’t, in theory, overlap batteries.

This occurs for a number of reasons:

  • there is no way (below it will be told what conditions are needed for this operation);
  • They do not see the need for this.

In particular, if you have installed a new, contemporary radiator, why is it worthwhile to block water in the battery? The coolant is actually pumped under high pressure through the entire network at the end of the heating season and during test runs in preparation for the upcoming New Winter. This indicates that it contains mechanical impurities, or deposit fragments that have grown inside of outdated pipelines.

Remember to disconnect the device from the water supply at the end of the heating season before using it again. This will keep it using the same brand-new, dependable

There is a chance of clogging when the tainted fluid goes through the radiator; this won’t be evident until the heating season starts and the radiator is unable to operate at maximum capacity. It might need to be disassembled and cleaned. It is worthwhile to cut off the heating battery’s coolant supply in order to prevent such issues.

What is required to overlap heating devices?

The following should be done if the apartment is overheated or if you need to disconnect the radiator without calling the plumbers to block the entire heating riser in the entrance:

  • There was a vertical jumper between the pipe of the feed and the return – bypass, it is on it that the flow of the coolant will pass, without falling into the installed battery after you block it. Lack of bypass automatically means that you are blocking the flow for the entire riser.
  • On the pipes of the feed and the return between the bypass and the heating radiator, ball valves with Americans should be installed. It is they who make it possible to make a shutdown.
  • Ideally, at the entrance, an air valve is installed into the radiator.

Take note! It is not possible to lower the heating of the batteries by adjusting the coolant flow with ball cranes! This reinforcement is turned off; its haphazard use causes leaks and the crane to be destroyed.

In light of the aforementioned, the battery may be separately disassembled for maintenance or replacement if ball valves are installed but there is no bypass; however, this cannot be done during the heating season.

A heating appliance with a bypas installed

Installed parallel to the radiator, a bypass (jumper) typically symbolizes a pipe whose diameter is one step less than or equal to the eyeliner’s diameter. Make sure to install a bypass if you intend to install a radiator with a thermostat or block the batteries after the heating season. If not, you will cause the neighbors’ and the coolant’s temperature to drop.

Is it possible to make a shutdown by blocking both taps?

Assume that while the system’s coolant was still hot, you simultaneously closed both of the taps.

With a basic understanding of physics, we can readily comprehend that:

  1. When water cooling in the battery, its volume will decrease;
  2. This will lead to the formation of a vacuum in a closed space of the radiator;
  3. As a result of the resulting pressure, the battery is deformed or lost tightness, it will need to replace it.

Thus, if you’re wondering how to block the battery when the apartment is hot, you already know that shutting off both taps won’t work in this situation! The only thing left to do is determine if it makes sense to use both taps once the heating season is over and the coolant has cooled.

The cost of the central heating system is yearly, as we already know. In certain places, if repairs are necessary, the coolant is drained and then refilled. That means your radiator is filled with a liquid.

The following happens if you block the upper and lower valves simultaneously:

  1. A variety of chemical processes occur in the liquid inside the battery, since the coolant cannot be chemically clean;
  2. As a result of these processes, gas formation occurs;
  3. Since gases do not have the possibility of exit, due to increased pressure, the radiator can be depressurized.

Therefore, even though the coolant temperature is indoors, it is strongly not advised to block both shut-off taps if the battery is not installed on the battery (Maevsky crane).

How to block the battery correctly?

It is incredibly easy to disable the heating battery; all you need to do is close one crane while keeping the other open. But an overlap of cranes?

As far as we can tell, the heating riser gets its water supply from below.

  • The upper crane is closed, and the bottom is open. If repair work is carried out from the neighbors from below or in the basement, or on a branch that feeds the house, the coolant will merge, and your radiator will be devastated. If it is steel or cast -iron, this will provoke corrosion.
  • The lower crane is closed and the upper is open. Regardless of any repairs, the radiator will be filled.

Consequently, we discovered how to block the battery for the summer by simply closing the lower ball crane.

When the cold weather arrives, pay attention to the advertisements at the entrance regarding the start of the heating season. Next, redraw both ball valves to allow the trash to pass through the bypass rather than into the radiator. In this scenario, a battery rupture with closed cranes does not pose a threat to you because the radiator will not be able to build up enough pressure within one or two days. Additionally, the apartment does not have time to freeze during this period; in particular, a small amount of heating will come from the riser.

How can the heating battery be turned on? This is a simple process that only requires opening both ball valves to initiate normal coolant circulation through the radiator.

When you hear the sound of water murmuring in the system on the first day of heating, do not hurry to open ball valves. You can use the Maevsky crane to open them the following day in order to release air. Take note! You need to have an air vent on your radiator if you live on the top floor. By doing this, the creation of air plugs—which prevent the heating device from working—will be prevented.


You can choose how to get ready for the upcoming summer heating season by knowing how to shut off the heating battery.

This is going to be necessary:

Plumbing that will obstruct the riser’s water supply should be involved in the professional installation of bypas and ball valves. Remember that welding and the necessary tools are needed.

Heating battery replacement on demand

Ball cranes and bypass present a chance:

  • ensure the safety of their batteries from corrosion and pollution;
  • Do not suffer from the heat with sharp warming during the heating period;
  • ensure security in the event of an emergency – if the radiator fails, it can be turned off from the system, while the neighbors will not suffer from the flood or the lack of heat;
  • At any convenient time, replace the old radiator yourself with a new one;
  • Remove batteries for flushing or coloring.
  • Successfully use modern radiators with a thermostat without interfering with neighbors.

Comfort and security are important considerations when organizing apartment heating.

How do I properly block the heating battery?

All of the following require turning off the batteries: fixing the radiator, heating the apartment, and repair work. We’ll explain how to properly block the heating battery in this article.

If you need to block the radiator without removing it

If there is a heating battery on the shut-off valves—ball valves—it is not difficult to block it in case you need to turn it off for the summer because of the heat. Turn the incoming and outgoing pipes’ crane handles all the way to the end. As a result, the coolant flow overlaps.

The taps are open in this picture. The cranes in the overpan’s cut valves are positioned perpendicular to the pipe.

An incoming pipe frequently has a unique adjustment valve. It can also be used to obstruct the pipe. But maintaining the room’s temperature within a certain range is its primary duty.

The following situations involve overlapping the radiator without disassembling it:

  • Battery painting is required (in the heating season).
  • Rinse of the battery is required.
  • It is necessary to replace the gaskets and nipples.
  • It is necessary to block the heating battery for the summer.

In order to maintain a warm and comfortable home throughout the winter, it’s critical to comprehend the fundamentals of heating systems. Understanding how to open a battery or heating radiator tap is one essential skill. This easy but important task makes sure that heat is distributed throughout the house in an efficient manner. In essence, by turning the tap counterclockwise, hot water can enter the radiator and warm it up, warming the room around it. On the other hand, to control the temperature, turn the tap clockwise to close it and stop the hot water flow. Ensuring comfort and energy efficiency in our living spaces throughout the winter months is a small action that makes a big difference.

If you need to block and remove the radiator

The best time to complete radiator removal work is after the heating season has ended. There are several considerations to make if work needs to be done during the heating season. You can only remove the battery in a single-pipe heating system with vertical wiring if there is a bypass.

Pipes indicate such a system; one originates from the ceiling and joins the radiator, while the other exits the radiator and vanishes into the floor. A jumper that connects the input and output pipes is called a bypass. This pipe is either slightly smaller or about the same diameter as the main pipes. The idea behind bypass is this: when the radiator is unplugged, water starts to move along the riser and through the bypass instead of the battery. In this instance, the riser is operational, and the heating in the apartments next door remains on.

In the event that the system consists of two pipes, shutting off the taps is sufficient before removing the battery.

Remember that the battery is always filled with water

The battery is filled with liquid throughout the year. Water drainage is carried out only for a short time in the process of centralized repair work. Therefore, if it is planned to replace the battery, just turn off it is not enough – you need to drain the water. Why the system is constantly filled with the coolant? It is extremely undesirable for oxygen to fall into the heating system. When the water merges, its place takes air with water vapor. 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, t.e. does not lead to corrosion. Therefore, for the heating system to serve for a long time, it is always filled.

Step 1: Locate the valve on the heating pipe connected to the radiator.
Step 2: Turn the valve clockwise to open it.

Although turning on a heating radiator’s tap may seem simple, doing it correctly is essential to ensuring effective heating and preventing problems. You can efficiently control the temperature in your house and keep your living space comfortable by taking a few easy precautions.

Finding the tap on the heating radiator is crucial first. Usually located on the left or right side of the radiator, this valve is located at the bottom. It looks like a tiny lever or knob that can be used to adjust how much hot water enters the radiator. Before continuing, take a moment to become familiar with where the tap is located.

Once you’ve located the tap, open it by carefully rotating it counterclockwise. To begin, slowly turn on the tap to let hot water trickle into the radiator. This guarantees uniform heating throughout the space and lessens the chance of unexpected temperature swings. Refrain from opening the tap too quickly as this may cause leaks or harm to the valve.

There might be a slight hissing sound when you open the tap; this is normal and means that air that has been trapped inside the radiator is being released. By removing air pockets that may be preventing hot water from circulating efficiently, this procedure, also referred to as "bleeding the radiator," helps to increase heating efficiency. After the water starts to flow consistently, keep the tap open and shut it firmly to keep the desired temperature.

It’s crucial to routinely inspect the radiator to make sure the tap is always open and clear of obstructions. The flow of hot water can be disturbed by a partially closed or blocked tap, which can lead to inconsistent heating or decreased efficiency. In addition, keep an eye out for any drips or leaks near the tap and fix them right away to avoid water damage and preserve the integrity of your heating system.

You can open the tap on your heating radiator with confidence and maximize comfort and energy savings by adhering to these easy guidelines. Always use caution when handling the tap, and if you have any questions or concerns about your heating system, get professional help.
