Methods for connecting panel radiators. Connecting a heating radiator

The heating system is one of the most important elements home improvement. Heating a house directly depends on the selected heating system and the way in which it was connected. Unfortunately, not everyone knows how best to connect a heating radiator with their own hands.

But first, it’s worth understanding the types of heating systems. This is necessary, since the connection may have its own characteristics depending on the selected system.

Types of heating systems

Depending on the connection principle, there are one-pipe and two-pipe heating systems.

Single-pipe system is the most common, as it is installed in most apartment buildings. It is a looped pipe to which heating elements are connected in series.

So called because only one pipe is used to supply water to the radiators and return it to the boiler. This connection method has a number of positive features and disadvantages.

Advantages of such a system:

cost-effectiveness in terms of required materials;
small time costs during installation;

Its disadvantages are:

There is no possibility of top connection;
Due to the series connection, the heat output of the first heating element is much higher than that of the last one in the system;
Heat transfer cannot exceed the rate calculated during installation;

Two-pipe system - differs from the previous one in that independent pipes are responsible for the supply and return of water. Also, when using this model, radiators are connected in parallel.

Advantages of this connection method:

the ability to regulate the coolant supply by installing a tap in front of the radiator;
uniform heating of all elements;

The disadvantages are greater consumption of materials and a more labor-intensive installation process.

At the moment, there are various schemes and methods for connecting radiators. But there are several generally accepted features that are recommended to be taken into account, regardless of the installation method.

The main place to install radiators is the area under the windows. This is done to keep cold air away from the glass into the house and also prevents condensation from occurring.

In this case, the length of the device should not exceed 70% of the window width, otherwise the windows will periodically fog up. Also, for optimal heat circulation, the radiator should be located from 8 to 12 cm from the floor, and from 3 to 1 cm from the wall.

Before installation, check the heat supply system, since depending on it, different types of radiators may be needed.

Connecting a radiator at home

Before direct installation, you should make sure that all the elements necessary for installation are available. If a single-pipe connection method was chosen, it is recommended to purchase a bypass, which will allow you to remove the radiator being installed without having to shut off the entire system.

Also, according to the size and connection method, connecting elements are selected if they are not included in the radiator kit. This also includes shut-off valves and squeegees, which are also selected by size.

It is highly advisable to install a Mayevsky valve in the structure, which will periodically bleed accumulated air from the system.

There are a large number of photos on the Internet demonstrating the connections of heating radiators, for choosing the optimal configuration of components.

It is worth noting that when installing any types of radiators with the exception of cast iron, you should not remove the packaging until the installation work is completed.

Instructions for correctly connecting the radiator

One of the fundamental operations is marking and installing brackets. It is recommended to do this in accordance with the above instructions, or according to the radiator manufacturer's instructions.

It is important not to allow too much distortion, as this can lead to undesirable consequences in the form of stagnation. After installation, the device should rest tightly on all fasteners.

Next, you should unscrew all the plugs from the radiator. If a single-pipe method is used, first of all a bypass is connected to the radiator, which is pre-equipped with a valve. Otherwise, a control valve is connected to the device using a squeegee.

Using drives, heating element connected to the heating system. To ensure sealing, it is recommended to use tow or a similar sealant if necessary.

The installation of the radiator into the system is completed, but for its full operation the device will still require pressure testing. To carry out this procedure, it is recommended to contact a plumber, as professional equipment will be required.

Photo of the process of connecting heating radiators

What does it look like correct connection heating radiator? We will analyze the connection diagrams used in private houses and city apartments, and the pipes, fittings and elements of shut-off and control valves used for this purpose. In addition, we will find out what mistakes can be made during design and installation heating system.

Circuit diagrams

If in a city apartment the layout of the heating system as a whole or its individual loop does not depend on our efforts, then in a private house the circuit is designed from scratch.

Two fundamentally different schemes can be distinguished:

Single-pipe, which is the only bottling around the perimeter of the heated building. Heating devices are installed parallel to the filling.

Note: sequential installation of batteries is also practiced; it is inconvenient because it does not allow independent adjustment of the devices.

Two-pipe— independent feed and return bottling. Each radiator acts as a jumper between them.

The advantages of a single-pipe scheme are low cost, ease of installation and exceptional fault tolerance. Disadvantages are a significant temperature difference between the first and last heating device, as well as the difficulty of laying around the perimeter of the house in the presence of high openings and panoramic windows.

The two-pipe scheme is devoid of these disadvantages, but under certain conditions it can create much more serious problems for the owner. The batteries closest to the boiler dampen the difference between pours, which slows down the circulation in distant devices. That is why the two-pipe requires mandatory balancing - throttling the connections and adjusting them bandwidth to equalize temperatures.

This problem is elegantly avoided in a passing two-pipe system - the Tichelman circuit, all of whose loops are of equal length.

Radiator insertion

What are the possible ways to connect heating radiators to bottlings and risers?

Name	Description	Peculiarities
Lateral one-sided	The connections are connected to the upper and lower collectors on one side of the heater	With a small number of sections it ensures maximum heat transfer. If the number of sections is more than ten, the edge of the radiator farthest from the connections will cool down. Silt accumulates in the outer sections over time
From bottom to bottom	The connections are connected to both plugs of the lower manifold	The heat transfer of the device is slightly reduced due to slow circulation through the upper collector. The radiator does not require flushing: sections do not silt
Diagonal	The connections are connected to the top plug on one side of the radiator and the bottom plug on the other side	Heat transfer is maximum at any radiator length. The bottom of the sections from the side of the blind bottom plug is silted

Please note: in a closed autonomous heating system, you can forget about the problem of silting of batteries.
A small amount of suspended matter contained in the coolant quickly collects in the mud pan and does not create problems in the future.
Accordingly, it makes sense to choose those types of heating radiator connections that will ensure maximum heat transfer.

Errors

Incorrect connection of heating radiators can lead to malfunctions of the central heating system, autonomous circuit, or seriously reduce the heat transfer of the device.

What mistakes can you make when installing batteries?

Inserting your radiator between the supply and return risers on any floor except the top one will make your neighbors on the riser freeze. The coolant will circulate through a small ring - through your battery, but the heat transfer of all devices above the improvised jumper will drop sharply.
Insertion of a radiator with any shut-off or throttling valves on the connections without a jumper in front of the valves or throttles. In this case, turning off your tap will stop circulation throughout the entire riser.

The side connection of a multi-section radiator, as already mentioned, will lead to a decrease in the heat transfer of the outer sections.
The connection will also lead to a drop in thermal power relative to the nominal heating radiators undersized eyeliner. The norm is a pipe DN15 (1/2 inch) with a number of sections up to seven and DN20 (3/4 inch) with a larger number of sections.

Selection of materials

The choice of pipes, batteries and fittings affects the efficiency and safety of the heating system at least as much as its design. What materials should be preferred in different cases?

Central heating

The standard operating parameters of the central heating system (4-6 kgf/cm2, 40-95 C) seem to allow the use of any modern pipes, batteries and fittings.

However, practice shows that it is better to refuse some of their types:

The calculated value of the coolant temperature is often exceeded in severe frosts. When there are widespread complaints about the cold in apartments, it is sometimes practiced to operate elevator units without a nozzle, with the suction muffled. In this mode, the batteries can heat up to 130 - 140 C.
Abrupt closing of any element shut-off valves due to the incompetence of the mechanic or a breakdown will lead to water hammer with a short-term increase in pressure to 20-25 atmospheres.

Cast iron radiators are designed for a pressure of 9 - 15 atmospheres and can be destroyed by water hammer.

It is the likelihood of emergency situations that leaves its mark on the choice of equipment for central heating.

Pipes

For installation of liners the following can be used:

Steel VGP (water and gas) pipe with welded joints;
Galvanized VGP pipe with threads. Welds are contraindicated for its anti-corrosion coating: when high temperatures zinc burns out;
Corrugated stainless pipe on compression fittings.

The latter option is attractive because it can be easily installed with your own hands using the simplest tool - a pair of adjustable wrenches. Price corrugated pipe with a diameter of 1/2 inch it is about 200 rubles per linear meter.

Radiators

The following are used in central heating systems:

, which are a coil of pipe with fins that increase heat transfer;
Bimetallic radiators. The steel core makes them resistant to pressure surges up to 25 - 40 kgf/cm2;
In rooms where aesthetics do not play a decisive role, the practice is to install homemade all-welded tubular radiators (registers). As a rule, connecting steel heating radiators is done with black steel pipe on welded joints.

Autonomous heating

Pipes

Fully controlled parameters of autonomous circuits allow the use of inexpensive and durable polypropylene and metal-plastic pipes.

There are a couple of subtleties associated with their installation:

For metal-plastic, press fittings are preferred rather than compression fittings, which better withstand numerous heating and cooling cycles;
For polypropylene, it is desirable to have reinforcement that reduces the elongation of pipes when heated.

Radiators

Everything is simple here: our choice is cheap, aesthetically pleasing aluminum batteries with high heat dissipation.

Aluminum sectional batteries are an excellent choice for an autonomous circuit.

Fittings

For connecting the heating device to taps and connections recent years American fittings with a union nut are widely used, making it possible to make the connection quick-release.

The following can be used as control and shut-off valves:

Ball valves;
Cone valves (throttles) that allow you to regulate heat transfer manually;
Thermostatic valves with thermal heads allowing automatic maintenance set air temperature.

On upper floors apartment buildings and in cases where the upper radiator collector is the top point of a separate circuit loop, the radiator plug is equipped with a Mayevsky tap - a simple device for bleeding air jams.

Conclusion

We hope that our review of connection diagrams and materials used in heating systems will help the reader accept right decision when planning own repairs or construction. The video in this article will offer additional thematic information to his attention. Good luck!

Without a high-quality heating system, no home will be as comfortable and cozy as possible. Especially if it is located in Russia - after all, our country does not have a mild climate. When planning a heating system in own home and what kind of heating radiator connection system there will be, we try to make sure that it heats the house or apartment well, is of high quality and works without failures.

But many owners add one more requirement, which, it should be noted, is quite logical. The heating system must also be economical. That is, its acquisition, installation, and further exploitation, and which connection of heating radiators is better should not cost the owner a pretty penny, as they say.

One of the most common ways to save on a heating system is to purchase and install it without the involvement of specialists.

And it should be noted that even those who have never dealt with heating systems before cope with this task perfectly. Of course, in order to do everything correctly, you need to familiarize yourself with some information, including heating radiator connection diagrams. Let's look at ways to connect heating radiators and how best to connect a heating radiator for you.

The principle of connecting radiators

Heating devices can be connected to the system in different ways. Let's look at examples of connecting heating radiators. In many ways, the choice of radiator type depends on its size and location relative to other radiators in the system, as well as the type of the system itself.

There are the following methods for connecting heating radiators: lateral, diagonal, heating radiators with bottom connections, series connection of heating radiators and parallel.

The most common include side connection and heating radiators with bottom connections. Let's take a closer look at these types:

side connection. This method is characterized by connecting the inlet pipe to the upper pipe, and the outlet pipe to the lower one. That is, both pipes - both the supply and the outflow of the coolant - are located on one side of the radiator. This method is quite common for the reason that it allows you to achieve maximum heating of the radiator, and, accordingly, maximum heat transfer. However, heating radiators with side connections should not be used for a large number of sections - in this case, the latter may not be warmed up enough. However, if there is no other connection method, then to fix the problem you should use a water flow extension.
heating radiators with bottom connection. This option is used if heating radiators with bottom wiring pass under the baseboards or floor. The bottom connection is called the most beautiful - heating batteries with a bottom connection and coolant supply and outflow are hidden under the floor and connected to the radiator using pipes directed to the floor.

Types of heating systems

Today there are quite a large number of types of heating systems. Each of them has its own characteristics for connecting radiators. Undoubtedly, if you decide to hire a specialist to install the batteries, he knows all this. But if you plan to install radiators yourself, then you need to distinguish between the types of connection of heating radiators - after all, you need to know which system will function in your home.

Single pipe system

This type of heating is common in multi-storey buildings. Easy planning and installation, as well as minimum quantity The materials used make it very profitable.

But single-pipe connection of heating radiators has a significant drawback - there is no possibility of adjusting the heat supply (degree of heating of the batteries). And in some cases this is a significant minus.

In this case, the heat transfer of the system is calculated when creating a heating project, and subsequently fully corresponds to the specified parameter.

The operating principle of this heating system is simple - heated coolant is supplied to the battery through one circuit. And the outflow of the cooled coolant is carried out through a different circuit. All heating devices in the system are connected in parallel. A significant advantage of a two-pipe heating system is that it is possible to control and, if necessary, adjust the heating level. To do this, special valves are installed on a separate radiator for two-pipe connection of heating radiators. It is important to remember that when connecting radiators, you must strictly follow all the rules specified in SNiP 3.05.01-85.

Where is the best place to install a radiator?

Heating radiators installed in any room, in addition to the heating function, have another, no less important – protective function. That is, the flow warm air, coming from the heating device, creates a kind of shield that protects the room from the penetration of cold air. And, in this case, it does not matter how the radiators are connected - parallel connection heating radiators or is it serial connection heating radiators.

It is the creation of such a barrier from the cold that forces us to install radiators where cold air can leak in - in the niche under the windows.

Therefore, whether parallel or serial connection of heating batteries will be in this case does not matter.

In order for the room to be maximally protected from the cold, before proceeding directly to the installation of radiators, it is necessary to correctly determine the places where they will be located. This is not an extra precaution - after all, it will not be possible to change anything in the future.

One more important feature- you should not only know where exactly to place the batteries, but also how to do it correctly, and in the future - what the connection diagram for the heating radiators will be.

In particular, there are several rules regarding at what distance from surfaces the heating device should be installed:

from the bottom point of the window sill to the top point of the radiator there should be at least 10 cm;
from the floor surface to the bottom point of the radiator should be at least 12 cm;
there should be at least 2 cm from the back of the radiator to the wall.

Types of coolant circulation and connection options

The coolant, which in most cases is water, can circulate in the heating system in two ways - forced and natural. Forced circulation implies the presence of a special pump in the heating system, through which the coolant is moved. The pump can be an element heating boiler(that is, it is built inside) or it is installed directly in front of the heating boiler - on the return pipe. When developing a connection diagram for heating batteries, the location for the pump must be correctly determined in advance.

A system with natural circulation of the medium is an excellent solution for those homes that often experience power outages. The movement of the coolant is based on elementary laws of physics. In such a system, the boiler is non-volatile.

In many ways, the types of connections for heating radiators depend not only on the type of coolant circulation. In addition, it is also necessary to take into account the duration of the system pipes and the peculiarities of their location.

This type of radiator connection assumes that both the hot coolant supply pipe and the return pipe will be connected to one side of the battery. Using this connection principle is the most rational for one-story houses. It is especially suitable if you plan to connect fairly long radiators - up to 14-15 sections. However, if the number of sections is more than 15, the heating efficiency may decrease - that is, the last sections of the radiator will be colder than those closer to the pipes. Therefore, in this case, you should choose other options for connecting heating radiators.

Saddle and bottom connection

This connection is suitable for those systems whose pipes are installed under the floor surface. In this case, there will be only a small section of pipe above the surface, which is connected to the lower pipe. In this case, the inlet pipe is mounted on one side of the radiator, and the outlet pipe on the other. The disadvantage of this connection method is significant (up to 15%) heat loss. In the upper part, the radiator may not warm up completely.

Diagonal connection of heating radiators is best used for radiators with a large number of sections. The design of the radiator allows the coolant to be distributed within the sections as evenly as possible - this makes it possible to obtain maximum heat transfer. The essence of the connection is simple - the heated coolant supply pipe is connected to the upper branch pipe. And a return pipe is connected to the lower pipe on the other side of the radiator. The advantage of this type of connection is minimal heat loss - it is only 2%.

The quality of heating the room will depend on how correctly you determine how to connect radiators to your heating system. The proposed options for connecting heating batteries are extremely simple and of the highest quality.

Connecting heating radiators

When building a house or just when major renovation In a private estate or apartment, the installation of heating radiators should be done after elements such as doors and windows have already been installed. In this case, you must determine in advance which connection of heating radiators you will use, and in addition, of course, prepare necessary materials and tools.

How to properly connect a heating battery? The process of installing the radiator itself does not take much time and effort. First of all, you need to install the battery mounts. Their number and location directly depends on the number of radiator sections. Next, we connect the pipes, install the radiator itself and connect everything. Let's look at an example of how to connect a heating radiator using polypropylene pipes.

Heating system options

The most common and popular are single-pipe and two-pipe heating systems. Let's take a closer look at each of them and the correct connection of heating batteries in each case.

The single-pipe heating system is used today mainly for multi-storey buildings.

The hot coolant spreads through the pipes from top to bottom, evenly distributed throughout all heating devices. Such a system is quite easy to install and requires a relatively small amount of materials. But at the same time, it also has a number of disadvantages:

there is no possibility of adjusting the degree of heating of individual radiators;
on the lower floors the temperature of the radiators can be significantly lower than on the upper floors, since the coolant reaches them already cooled down;
in the event of a breakdown on any floor, the entire riser is switched off;
It is quite difficult to disconnect from the system to install autonomous heating.

A two-pipe heating system is most often used to create heating in private houses and cottages. It involves connecting two pipes to the radiator at once: one carries hot coolant to the battery, and the other drains cooled water. It is important to take into account that all radiators in a two-pipe system are connected only in parallel.

A two-pipe heating system has several significant advantages. First of all, the temperature of all radiators will always be equal, no matter how far from the boiler they are installed.

In addition, with this type of system, it is possible to adjust the degree of heating of each individual radiator - this allows you to create the most comfortable temperature in each room.

A heating system of this type includes the following elements:

radiator with a valve at the top and a plug at the bottom;
radiator plugs;
valve with thermostat;
bypass;
shank;
stopcock;
couplings and locknuts;
heating pipes (metal, polypropylene).

It should be noted that the same set of components, with the exception of a valve with a thermostat and a bypass, is suitable for installing a one-pipe heating system.

Types of connection of pipes and radiators

Connecting heating batteries can be:

lateral - this connection of the battery to the heating system is the most common. With this type of connection, the pipe with the hot coolant is supplied to the upper branch pipe, and the return pipe is connected to the lower one. That is, both pipes are located on the same side of the radiator. This connection of heating batteries is the most productive - it results in the least heat loss. However, you should not use such a connection for heating radiators, the number of sections of which is more than 15.
diagonal connection heating batteries – used for fairly long batteries. With this type, the hot coolant pipe is connected to the upper radiator pipe on one side, and the cooled coolant outflow pipe is connected to the lower pipe on the other side. This connection of the heating radiator allows the coolant to spread throughout the radiator as evenly as possible. It is important to consider that if you choose a diagonal connection of heating radiators among themselves, but at the same time the supply hot water is carried out through the lower pipe, and the outflow through the upper, the efficiency of the system will decrease by about 10%.
bottom connection heating radiators. It is used only when the heating pipes are hidden under the floor. The efficiency of radiators connected in this way is approximately 10% lower than those connected by the side method.

Types of radiators for piping

Before you start creating a heating system and before connecting the radiators, you need to determine what types of radiators you want to use. Today there are a huge number of types of batteries. They may differ in:

material;
the principle of how to connect a heating battery;
wall mounting method.

Today the most common types of radiators are:

– are a relatively thin panel of flat steel plates. How to properly connect a heating radiator of this type? Radiators of this type are connected from the side or bottom.

Steel panel batteries

sectional radiators. Lightweight sectional model made of aluminum (there are also bimetallic radiators of this type). How to properly connect the heating batteries in this case? Such batteries can be connected in several sections or one at a time. For such radiators, it is best to use polypropylene pipes, the connection type is lateral.

About connecting bimetal in the article: Connecting bimetallic heating radiators.

It is noteworthy that recently in apartments with central heating bimetallic batteries are increasingly being installed, abandoning cast iron ones. The reason for this change is due to a number of reasons. First of all, cast iron radiators are heavier and bulkier. Moreover, due to poor quality water, used as the coolant of the heating system, sediment quickly forms in such radiators, sand and rust appear - and these factors significantly contribute to a decrease in the heat transfer of radiators. WITH bimetallic radiators no such problems arise.

For a private home, you can choose panel radiators. They can be either aluminum or steel - it all depends on the customer’s wishes.

The main thing is to comply with all rules during installation. It is important to remember - if you have a copper pipeline, then both steel and aluminum radiators. And if the pipeline is made of ordinary pipes, only aluminum batteries are allowed to be installed.

What is needed to connect radiators

Creating a heating system is enough complex process. Meanwhile, by following all the rules and a clear sequence of work, even a beginner can handle it. How to connect a heating battery correctly? The main thing is attention. For high-quality installation and connecting radiators, some components are required. In particular:

adapters with right and left threads (fittings);
tools for high-quality screwing of adapters;
plugs, manual air vent, key for bleeding air, adapters;
shut-off valves, ball valves, valves;
pipes.

Tying with polypropylene pipes - implementation principle

Recently, polypropylene pipes have become increasingly popular. Of course, the correct connection of heating radiators and piping can be done with any other pipes, but most professionals still recommend choosing these.

For piping, it is most rational to use polypropylene corner ball valves - they are much easier to install, and their cost is relatively low.

Tying with polypropylene pipes is carried out as follows:

a coupling with a union nut is inserted into the multiflex, connecting to any output;
Pipes are fixed to the wall using pre-attached brackets. It is important that they do not touch the wall, but are 2-3 cm from its surface.

The advantage of polypropylene pipes is that they can be laid in the wall itself, and the edge of the pipe required for piping is brought out in close proximity to the radiator. A variety of fasteners can be used to secure batteries. Most often, professionals use a pin connection for this purpose, fixed to the wall surface. If you want to hang radiators, use regular brackets for this. A small clarification - panel batteries are (mostly) sold complete with fasteners. But for sectional radiators Mount must be purchased separately

We already practically know how to properly connect a heating radiator. The taps are connected as follows:

initially the crane must be disassembled;
a fitting with a union nut is screwed into the radiator;
Using a special wrench, tighten the nut.

To properly perform such a simple, and at the same time, quite important action, you will need to use a special wrench - without it you will not be able to tighten the “American” properly.

In addition to this key, during installation and piping of radiators, as well as during how to connect two heating batteries, you will also need:

seals;
set of keys;
tow;
thread paste;
threads for carving.

Features of radiator installation

When installing heating radiators and when connecting a heating radiator, the requirements specified in SNiP must be strictly observed. In particular, this applies to keeping required distance between the radiator and the wall, floor and window sill:

the distance from the top of the radiator to the window sill must be at least 10 cm. If the specified gap is lower, this may impede the movement of heat flow - thus, the room will not warm up as well;
the distance from the bottom of the radiator to the floor should be at least 12 cm. If it is smaller, there is a risk of a significant increase in the temperature difference at different heights of the room;
the distance from the rear wall of the radiator to the wall must be at least 2 cm. Otherwise, the heat transfer of the radiator will be impaired.

It is also important to take into account that the installation method and how to correctly connect heating radiators also affect the quality of heating the room. So, possible options for installing radiators:

V open form under the windowsill - maximum efficiency heating systems – 96%-97%;
in an open form in a niche – the efficiency is slightly lower – 93%;
in part closed– there is a decrease in efficiency to 88%;
completely closed – heating efficiency is only 75%-80%.

Tying a heating radiator and how to properly connect a heating battery can be done using various types pipes The main thing is strict compliance with all specified requirements and rules. If the radiator connection is made without errors, the heating system will not require repairs for many years. Now we know how best to connect heating radiators - but it’s even better to ask professionals about this.

From experts you can hear the opinion that the single-pipe heating system is a relic of the past, however, it still stands among effective ways heating of private and multi-storey buildings.

One has only to slightly modify the well-deserved classic, and all the advantages of a single-pipe connection will appear when installing heating systems: comfort, coziness in the home and the possibility of local repair of the heating system without turning off the heat supply.

And also - saving money when the power supply to the area is turned off.

Single-pipe system: “highlights” of connection and real benefits during installation

Initially, the single-pipe heating connection system was the only profitable one: heating radiators were connected according to physical parameters « serial connection» .

The choice was based on economical pricing:

Costs halved on the purchase of conductors for coolant in comparison with two-pipe system.
Savings achieved when purchasing footers, fittings, taps.
Radiators of all existing brands were suitable for this system: from cast iron classics to “advanced” bimetal.

There were also some negative aspects: The radiators, sequentially looped, heated unevenly, the last one in the chain did not correspond to the specified (expected) temperature parameters. This was the case until experts discovered the principle of a “bypass pipe”, known as a bypass.

Pros of bypass

It is sometimes difficult for a homeowner to make a decision based on the recommendation of specialists when installing a single-pipe heating system about installing a bypass. The principle is simple: a bypass pipe is included in the design (this is the bypass), which will save material resources, and allows for local radiator repairs without shutting down the entire system. The latter is relevant for owners of private houses and for residents of standard high-rise buildings of the last century.

Photo 1. Radiator connected to the heating system. The arrows indicate the location of the bypass and ball valves.

For owners of a large living space with a single-pipe heating system, it will be advisable connecting the "stroke". It is a piece of pipe that is installed in close proximity to the radiator. Pipe diameter one position lower than the cross-section of the main pipeline. This is explained by the fact that when a carrier is supplied, water prefers to rush through channels of larger diameter. Thus, it becomes possible to painlessly begin repairing leaking radiator components for heating the house.

A gravity-fed system does not provide a comfortable (and adjustable) temperature in living spaces, which is where a bypass is needed. Craftsmen install a bypass pipe with a circulation pump and temperature sensors. It doesn’t matter if the power supply is interrupted - the bypass will direct water flows according to the “gravity” principle and in emergency mode. The bypass pipe brings savings to the homeowner up to 25% electricity bills, alternating between gravity and forced circulation coolant.

Attention! Install the circulation pump in the bypass pipe, adhering to the rule of “curvilinearity”: The more bends, the lower the thermal conductivity of the heating system.

The bypass is “surrounded” on both sides by ball valves to protect the water supply to a certain radiator.

Correct installation of the structure without a bypass pipe

This scheme will not require parallel pipe laying based on welding or fastening using adapters and fittings.

Primitivism in installation and some cost savings will subsequently bring a lot of problems to the homeowner. The most expensive item is shutting down the system due to local leaks in the pipeline or radiator.

Tools

To organize heat supply, you do not need to purchase special sets of tools - they will handle the task plumbing fixtures and those keys that are available home handyman. Add only specific tools to your home kit:

special keys for connecting American women;
tools for screwing on adapters;
torque wrenches for “delicate” parts.

Reference. Professionals advise not to purchase expensive equipment for attaching parts with a union nut. Copes with the task open-end (or adjustable) wrench with pliers. The first one holds, the other twists.

Connection diagrams and methods

With a single-pipe scheme for connecting heat supply to housing Several schemes for obtaining energy from a heat source are used.

Diagonal connection is an effective method. The pipes alternate with upper and lower connections within the border of one radiator: the heat input is at the top pipe, the output is at the bottom of the battery. This system has proven itself to be excellent when connecting radiators. over 10 links, the batteries warm up evenly.

Photo 2. Connecting a heating radiator in a diagonal pattern. Hot coolant is indicated in red, cold coolant in blue.

Bottom harness, according to experts, is less efficient in thermal conductivity, but is used in closed heating systems, when the pipes run horizontally from the boiler and are hidden under the floor.
Vertical connection based on the installation of a riser in the boiler area, the remaining elements are connected to it heating structure. The advantage of this method is the absence of air pockets when water flows by gravity.
Upper wiring (incoming and outgoing pipes are installed at the top on different sides) is used in radiators of a special design, where forward flow is excluded. The carrier descends down the first section and passes through the remaining links.

How to connect radiators correctly

When installing a heating system, it is important to install the radiators correctly, securing them to the wall under window openings. According to the standards, it is impossible for the distance from the floor and window to the battery to be less than 10 centimeters. The allowed gap from the wall is twice as small.

To secure these elements use 3 brackets for each unit: two are attached at the top points, one at the bottom.

Level the surface of the battery vertically; A slight lowering is allowed horizontally so that air does not accumulate in the upper part.

Achieve such a level that the radiator plugs directly fit the location of the pipes. Screw onto each battery Mayevsky crane(at the top point), install the plug down. If necessary, install heat controls.

With the help of adapters (futures) transitions are provided from right to left threads, from pipes of different diameters. To connect batteries to the pipeline, sold sets with fittings, adapters, couplings and taps. The kit is supplemented with gaskets that do not require additional waterproofing. Sometimes when threaded connection Gaskets do not save pipes and adapters, then use flax soaked in drying oil.

Important! Start screwing on the adapters by cleaning the pipes and joints: No paint is allowed at the joints. Sand until bare metal. Otherwise, the paint will peel off over time and the connection will leak.

At self-installation systems do not skimp on installing faucets— otherwise, minor repairs will have to be made when the system is turned off and the pipeline is cut.
