How to turn off the heating battery where to twist

The position of the open crane on the battery

Those who live in houses with central heating have questions on how to block the heating battery usually arise in two cases:

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

At the same time, this moment should be taken into account: the coolant is constantly inside the battery. It is drained only in the case of repair work in the system

This is due to the fact that the bulk of the heating devices installed in the houses of the old building, as well as the intra.House wiring are made of steel.

The fluid inside the heating battery contains a certain amount of oxygen in a dissolved form, which eventually completely reacts with the metal, as a result of which corrosion ceases.

It is impossible for a long time to leave a system or a separate heating device is incomplete. On the inner surface of a steel or cast.Iron battery there remains moisture that does not evaporate in a closed space for a long time.This significantly accelerates corrosion processes. Thus, the heat carrier merges only in exceptional cases.

Types of radiator cranes

As a rule, before entering the battery (radiator), taps of various types and structures are installed. This is done so that in the event of an unexpected radiator leak, not to block the entire system, but to stop supplying water to a specific damaged area. And also eliminate the flow of liquid from batteries with central heating. Over, the taps are installed both at the entrance, and on the “return” (2 pcs obtained. On one battery). It is recommended to use the same type of taps, the same design. The main design options are as follows:

Each type of crane has its advantages and disadvantages. As well as radically different designs and preferred installation places. But they have one purpose, stop or ensure the supply of working fluid into the radiator. The use of various types of locking reinforcement depends on the scheme of the heating system itself, the type of radiators, installation sites.

Overlapping the heating riser

The heating riser is a common property, and only a service organization can work with it. Zhek, DEZ, Daewoo, etc. To do this, you need to come to the organization and write a statement. It indicates the time for which the valve will be blocked. The riser’s shutdown service will cost about a thousand, the exact amount varies in different organizations and cities.

It is not recommended to independently perform manipulations with a riser without the knowledge of the management company. Even if you manage to agree with your neighbors, these actions will be illegal. If the fact of unauthorized access becomes known to the company, then it can go to court to recover a significant fine. In addition, find the required valve in the basement may be problematic.

How to disable the radiator

Before you remove the battery, you need to block the water supply to it. To do this, both taps turn 90 degrees clockwise so that the “flags” stand across the pipelines. If the valves are installed, we tighten their lambs to the stop clockwise. Which tank is the first to close, and which second does not matter.

The sequence of opening and closing shut.Off valves on the radiator matters when starting heating (if water was drained).

With a centralized launch

In apartment buildings, the coolant is drained for washing the system. If you were warned about such work, open all the valves on the battery in advance (including thermogol). Everything else will be done in the thermal point of the plumber of the house management.

With a local shutdown

Suppose you disconnected only your radiator from heating or did not manage to open it at the time of the general filling of the system with water. In this case, there is a risk of getting a hydraulicum if it is incorrect launch. The risk is minimal, but it is better to play it safe.

In what sequence to open the taps on the battery:

• Open the descent (Maevsky crane) and substitute the container under it.
• Slightly open the valve on the feed.
• We are waiting for the radiator to be fully filled with water.
• Completely pull the air through the descent.
• We completely open both taps.

Wiring heating systems can be different. To understand which of the taps is on the presentation, pay attention to the arrow that is located on its case. On the supply valve, the arrow indicates in the direction of the radiator.

Now you know which way to unscrew the taps and valves on the battery and in what sequence to do this so as not to damage the heating system.

How to make a house warmer without heating appliances?

The situation such as the rapid cooling of the apartment due to lowering atmospheric air is repeated annually. The owners should think about how to increase the heat efficiency of the dwelling. How to make the apartment cool more precisely, preserving the warmth over the summer longer?

You need to take care of the insulation of the house in advance. Experts say that through the glass it disappears up to 14% heat. Another 30 percent of thermal energy exits through the cracks in the windows and doors. 15% of warm air seeps out of the house through the entrance opening or a broken window in the entrance.

Heating has not yet been turned on, and blankets and rugs no longer save? There are several ways to help solve the problem.

Lawyer Old window frames. This is one of the main ways to eliminate heat leakage. Such work is not complicated, it takes a small amount of time. And its cost is minimal. As a result, drafts in the apartment will disappear.

Lay the gaps in the doorbells. This method will reduce the account for electricity by 15 percent. It is recommended to do the same with the front door in the vestibule.

Reference information: Similar measures increase heat efficiency by 20%!

Get out the outer walls of the apartment with polystyrene or mineral wool. If you have enough funds, you can think about such insulation of the apartment too, this technique gives a tangible effect. Just do not forget about the sealing of the interpanel seams of the building.

How to open a crane (valve) in a heating battery?

This is done to supply the maximum possible amount of coolant in order to ensure the premises with heat. To adjust the mechanism, it is necessary to turn the handle parallel to its own axis and pipe. For convenience, there are protrusions on the crane housing indicating restrictions on the degree of opening. This is done counterclockwise.

In this case, the circulation of the coolant completely stops. This is required to do this when it becomes necessary to reduce the temperature of the radiator to a minimum, for example, in the summer. The device’s handle in the “blocked” position should form an angle of 90 degrees with its axis and pipeline. In accordance with the protrusions, the movement of the handle to stop the circulation of the liquid should be closed clockwise.

Principle of operation

Bypas’s work consists in a complete or partial direction of the coolant bypassing the main pipeline. The bypass canal is needed in two cases:

Despite the general principal device, in each case, the bypass has a different purpose. For the radiator, it serves as a thermostat, directing excess water bypassing the heating device. When installing the circulation pump, the bypass is included in the operation in the absence of power supply as a binding. In both of the above cases, it provides an additional function. Allows you to dismantle the device without stopping the entire system, which may be needed for repair or if it is planned to replace the pump or radiator.

Main functions

The diameter of bypass installed between the radiator pipe at the input and at the output is less than the diameter of the supply pipe. It is such an installation that allows, in the process of repair and replacement of components and parts, as well as for their cleaning, to leave a system of efficient.

The bypass also accelerates the supply of the coolant when filling out the system or in the process of emptying. Use a bypass in single.Pipe heating systems, installing it as close as possible to the heating battery, but as far away from the riser as possible. In this case, it becomes possible to adjust the water temperature in the radiator, changing the intensity of its supply. A adjusting valve or thermoregulator is installed between the bypass and the radiator.

Signs of high quality

High.Quality certified bypass will have the following characteristics:

The correct procedure

Bypass is a small branch from a common riser in the form of a connecting jumper between the pipes. The presence of bypas will guarantee that you are blocking the battery only in your apartment, and not at the whole house. If your heating system is connected exactly as in the figures above, then in order to block the battery you need to use the taps. The question arises: the upper or lower tap should use?

You need to know right away that you do not need to close two taps! As we already know, hot water is walking through the pipes in winter, heating the heater. If both taps are blocked, then the water temperature inside will drop sharply. It would seem that we need it! But at the same time, the volume of water filling the radiator will decrease. And empty space will fill a vacuum that creates pressure inside.

As a result of excess pressure, the battery may crack or even burst! To blame heating painlessly, if you are hot, you just need to close the lower tap. The upper one remains open so that the heater is full and the vacuum and air traffic jams are not created.

That is, your procedure consists of 3 points:

Briefly about the main thing

You can block the radiator in an apartment building in the winter if it warms hard. This is done with the help of shut.Off valves and if there is bypas. In summer, the equipment does not completely close, since the absence of a heat supply fluid inside it harms it. The exception is cases when new equipment is installed. If the shutdown must be performed in the winter in the absence of bypass and locking devices, then the process is carried out on risers in the basement, but only after coordination with the HUE, the management company, etc. D. Now radiators are connected to heating pipes through a special locking reinforcement with a ball mechanism. It also lies in the principle of regulating the temperature of their work. Devices are mounted on feed and return. They also allow us to conveniently use bypass, mount the temperature controller, use the drain and gas removal devices.

What do you think. Whether it is necessary to install the third ball crane in the middle of the bypas so that it can be completely blocked?
