Mounting a heated towel rail is a completely simple task that absolutely any developer can handle. You don't even need the help of professional repairmen! The most important thing is to choose a convenient design, decide which mounting method you will use, and also choose the right size pipes for the heated towel rail.

The design of many heated towel rails is so concise that it looks great in any interior.

Systems and structures

To date, heated towel rails in the form of the Russian letters "M" and "P" have become the most popular. However, do not forget that in the markets and in specialized stores you can find the widest range corner models and various ladders. It's no secret that each of these models has its own characteristics, mounting methods, as well as price variations. When choosing a heated towel rail for your bathroom, there are many things to consider. various factors. After all, it is far from always possible to install exactly the model you like.

Most often, you have to mount what is most suitable for your conditions.

First of all, you need to consider the dimensions of your bathroom, and of course, the diameters of the pipes. For small bathrooms, U-shaped and M-shaped dryers are best suited. As for the large and spacious bathrooms, various ladders look great there, as well as rotary and sliding models. Moreover, they can be both quite large and quite small.

Towel dryer "Ladder".

Corner designs are also more suitable for small baths. Even considering the fact that heated towel rails are mounted in the corner of the room, they have enough free surface to perform their main function. Thanks to its unique design They are no worse than other models. They are just as effective, but at the same time cozy, compact and very attractive.

Remembering the attractiveness and beauty of the overall appearance, it is worth saying a few words about fittings for heated towel rails. The beauty of the overall appearance of the entire structure depends on the fittings. Pipes hidden in the wall look especially beautiful, in this case all fasteners (including fittings) are also hidden. However, this type of installation is more complex. It is much easier to mount the heated towel rail to external pipes. But in this case, the fittings will be visible.

Fittings and their types:

When installing the towel dryer Special attention it is necessary to pay attention not only to the choice of material for the structure itself, but also to the methods of its fastening. After all, not only beauty depends on them, but also the functionality and general practicality of the entire drying system. Moreover, if you can choose the right fittings for the dryer, the design can serve you much longer.

Those who are assembling the design of towel dryers for the first time may not know what fittings are. So,

fittings are small chrome elements that must be used during the assembly of the heated towel rail. The choice of fittings directly depends on the design you choose, as well as the material from which it is made.

The best option is when the entire structure (pipes and fittings) are made of the same materials. In stores you can find these types of fittings:

  1. Detachable extension. This type will help you adjust the distance from the heated towel rail to the wall to which it will be attached. They are used as a kind of support, for the connection of which at least two fasteners are required. Extension fittings are connected exclusively in front of pipe bends. This type of connector has one significant disadvantage- too long thread. However, dealing with this problem is very easy. Excess threads can easily be cut off or simply sharpened.

  2. Polymer winding. This type of fitting allows you to save yourself from the play that appears on the adjustment joints. If you manage to wind the winding correctly, it will be able to take the form that is required of it. You should also take into account the fact that this part will not be compacted over time.
  3. The crane is angular (corner). It is designed to directly connect the heated towel rail to the pipe central heating. Depending on the size of your pipes, you can choose either standard options for corners, or you can choose more convenient options. Angle fittings will help you change the direction of the pipes.
  4. Tee. This unpretentious connector will come to the rescue if you need to make several branches from central system, in different directions. This fitting can also directly connect the towel warmer and the riser. This also takes the bypass into account. The bypass allows you to turn off the heated towel rail as unnecessary and at the same time without creating obstacles to other heating grids.
  5. Cross fittings. With their help, you can branch the system in only two different directions.
  6. Fitting American. An American is a kind of crane with which you can dismantle the structure at any time. The convenience of this fitting is simply incommensurable, because you do not have to completely turn off the system. It will be enough just to turn off this valve, unscrew the nut and remove the structure. In this case, there are several main types of connection:
    a. nut-fitting;
    b. nut-nut (with an intermediate fitting);
    c. fitting-fitting (with an additional nut or coupling);

    Most specialists prefer "American".

  7. Coupling coupling. Performs almost the same functions as the American. The coupling helps to quickly disassemble and assemble all connections. This part has one feature - it has different diameters from different sides, which in turn helps to connect pipes various sizes. The turnbuckle can have both internal and external threads.
  8. Reflectors. This fitting does not allow moisture to penetrate to the mount.
  9. Plugs, caps, plugs. They completely seal the pipes.
    When buying chrome fittings for a heated towel rail, you need to pay attention to the quality of the thread. If the threads are uniform, then the quality of the fittings is high. It is also important to know that non-chrome metal joints are very easy to corrode. by the most the right option is the purchase of fittings together with a heated towel rail. So you can save yourself from searching for the right ones or exchanging those that already have, but inappropriate parts.

Fitting connection methods

Depending on the types of fittings, the following methods and methods of fastening can be distinguished:

  1. Threaded connection. This type is most often found when connecting pipes and other metal structures. A special advantage in this case is that the slicing process itself is completely uncomplicated. So, each developer will be able to make a threaded connection on their own, without anyone's help. As for the disadvantages, in the case of a threaded connection, this is poor tightness. It should also be noted that when the thread is exposed to sufficiently high temperatures, corrosion can develop, and this, in turn, affects problems during the dismantling of the structure.

    The threaded connection method can be called classic.

  2. Solder capillary. Used exclusively when mounting metal pipes. In this case, a wire is pulled between the fitting and the pipe. When heated, it straightens out, which allows you to completely fill the gap between the connecting elements. Capillary soldering is considered one of the most reliable and durable fastening methods. However, to do it yourself at home this method pretty complex.
  3. compression method. For fixing, a compression ring is used, which is fixed to the pipe with a fitting. The advantage of this method is that it can be used on pipes made of absolutely any material. It is also quite convenient in terms of accessibility to pipes (great even in cases where access to pipes is limited). But this method also has one significant drawback - it is very poor reliability.
  4. The pressing method differs from the compression method in that special pressing fittings are required for its implementation. In this case, a huge disadvantage is the factor that you have to use optional equipment. However, with regard to reliability, the pressing method is much higher than that of the compression method. The pressing method also has excellent advantages; it can be used for joints plastic pipes while soldering is completely unacceptable.
  5. Self-locking fittings. Such connecting elements have special rings on inner surface. When the pipes are connected to each other, due to the large number of teeth on the ring, fixation occurs. This mount is good and secure. It should also be noted that the design is assembled and disassembled quite easily.

    Their main advantage over other types of fittings is simply incredible installation speed.

Now, knowing the basic connection methods, you can choose the one that suits you exclusively. If you are going to install a heated towel rail yourself, you should not choose a connection method that you do not understand or do not know how to do. Better give your preference to more simple method but do it well and with quality.

One of the options for connecting a heated towel rail.

Pipe diameters and material selection

First of all, when selecting and purchasing accessories, you need to ensure that the diameter of the riser is in no case smaller than the diameter of the dryer in the connection area. AT the best option they should be at least equal. Situations are also allowed when the riser is larger than the towel dryer pipe. But in this case, it is necessary to make jumpers. As for the pipes themselves for heated towel rails, they can be of various sizes. The most common options are:

  1. For M-shaped and U-shaped dryers, pipes with a diameter of 0.25 cm (3/4) are usually used.
  2. Pipes 1 are also quite often used, the outer diameters of which are 0.32 cm. Such pipes are suitable for sufficiently a large number models, including even ladders and foxtrots.
  3. 0.4 cm diameter corresponds to a 1/4 pipe. It is used in the installation of foxtrots, as well as U-shaped dryers. It should be noted that among the variety of other models, such a pipe diameter does not occur at all. Since a pipe of this size is very difficult to bend into the desired shapes.

Pipes for heated towel rails are usually made of steel, stainless steel, and copper. Nowadays, stainless steel is increasingly being used for manufacturing. The thing is that it has enough access in terms of financial costs, and the polished surface helps to look attractive. Copper pipe models differ from stainless ones in high heat transfer. At the same time, copper pipes are the most expensive among a huge variety of models. As for steel, this material is practically not used in our time.

We hope that our article will help you choose a comfortable heated towel rail, as well as the best and highest quality fittings for mounting it. Good luck to you!

Fittings are devices necessary to connect individual parts of the pipeline into a single system. Different accessories are used for different pipelines. At the same time, for arranging one system, they can be of several types.

Properly selected fittings for the water supply of your home are a guarantee of reliable operation of the pipeline. And how to do this, the article will tell you.

Types of fittings

For the installation of water pipes, the following types of fittings are used:

  • Couplings are used to connect individual parts of the pipeline.
  • Corners are used to change the direction of pipe laying.
  • Tees and crosses are designed for branching the pipeline.
  • Sgons connect already laid pipes.
  • Adapters.

Tip: In places where the pipeline bends, you need to use flexible pipes, or special fittings.

The main types of elements for connection water pipes presented in the table:

Fitting type Purpose

They are installed when connecting various sections of the water supply system, sleeves, hoses, without changing the direction of pipe laying.

The diameters and material of the parts correspond to the diameters and materials of the pipes to be connected.

The main function of the element is to ensure a tight connection of even sections of the water supply.

Connects pipes that fit at right angles to each other, while changing the direction of their laying. The deflection angle can be 90° or 45°.

For connecting main and auxiliary pipes to each other at 90°, 67° and 45°.

It is used for branching 4 pipes in different directions. At the same time, one direction is the main one, the other two are auxiliary. The angle can be 90° or 45°.

Used for bends in the sewer system.

For their manufacture, steel, brass or ductile iron are used. Parts are used to connect metal-plastic and metal pipes. They are installed when connecting metal radiators to a polypropylene heating line. Units with such parts require periodic inspection: the nuts, over time, weaken, they must be tightened in a timely manner. For pipe diameters up to 40 mm, used threaded fittings. For larger diameters - flanged connections.

This is a type of threaded fitting. It consists of a split coupling and a union nut, which is tightened on the pipe after the fitting is in the required position, which ensures a strong connection of the elements. "American" quickly unwinds and allows you to dismantle a section of the pipeline without much difficulty.

These fittings are used for hot and cold water supply, in heating systems ah, and in pipelines with the presence of an aggressive working environment. They are installed on metal-plastic and metal pipes, using hydraulic press for crimping. Products cannot be used for polypropylene pipes; during installation, deformation of the latter is possible.

Are established in systems of heating, cold and hot water supply. They have high reliability, and the price is comparable to the price of press fittings. Require periodic control, are not used for closed installation.

Fitting materials

All connecting elements for the water supply network are classified according to the materials of manufacture.

They can be:

  • Copper fittings for water supply.

Benefits of using these products:

  1. When using copper products, the temperature range can be from (-200° C) to (+250° C).
  2. From exposure low temperatures The ductility and strength of copper do not decrease, but increase, unlike other materials.
  3. Resistance to formation of corrosion, harmful influence of an ultraviolet. Are not subject to destructive actions of many aggressive chemical compounds.
  4. Easy installation of copper elements.
  5. Low coefficient of roughness.
  6. Environmentally friendly material.
  7. Beautiful appearance allows you not to mask fittings, but to choose open gasket, making them design elements.

The disadvantages include:

  1. High cost.
  2. Incompatibility with other types of metals, for example: when connected to steel pipes, an electrolytic reaction occurs, which leads to corrosion of the metal.

Tip: To avoid corrosion, special adapters should be used.

  • Plastic.

Usage plastic productsbest option for plumbing system, especially if the fittings are compression.

Their advantages:

  1. Easy installation.
  2. Relatively low price.
  3. No corrosion occurs. React only to alkali and other aggressive chemical reagents.
  4. The most different options and modifications, including compression fittings that allow connection in knots at an angle.
  5. You can use plastic fittings for drinking water supply, heating, water drainage.

Detail flaws:

  1. Instability to ultraviolet rays.
  2. Low mechanical strength.
  3. Cancellation not always possible Wastewater, especially when the sewer is located in a cold climate.
  • From polyvinyl chloride - PVC.

  • Polyethylene - HDPE.

  • Polypropylene - PPR.

The use of PVC, polyethylene and polypropylene fittings is very practical solution, in which a reasonable ratio of quality and price, compared with products made from other materials.

Differ long term operation and environmental safety. Withstand high temperatures and large pressure drops within the system.

  • Brass.

They are most often used by home craftsmen when assembling a variety of pipelines with their own hands. The range of such products surpasses fitting sets from any other materials.

  • Cast iron - tees, turns, bends.

Such products are used quite rarely, but their relative cheapness keeps them on the market for pipeline parts. These are hard, but rather fragile parts, they are afraid of strong shock loads, especially in systems with the presence of water hammer - sudden pressure surges in pipelines with the presence of liquid in them.

  • Steel.

Their range is similar to cast iron parts, but more often products are made without thread, for welding, including for pipelines made of stainless steel.

Selection of fittings for the water supply system

Before purchasing accessories for water supply, it is worth getting acquainted with some recommendations of experts:

  • For joining polymer pipes, compression fittings are used: couplings, tees, adapters.
  • When installing threaded fittings on polymer pipes, it is necessary to provide easy access to them for fast elimination leaks.
  • Threaded fittings for polymer pipes should be selected so that they are put on the pipes with some force, which will prevent the system from leaking.
  • If it is not possible to avoid threaded connections in plastic pipes, it is better to use American fittings for reliability.
  • It is better to fasten metal-polymer pipes with metal or press fittings and reinforced combined threaded crimps.
  • Metal-polymer pipes are produced, the installation of which is carried out by welding. This improves the reliability of the connection and increases the resistance of the system to the perception of loads.
  • Metal pipes are connected by threaded metal fittings made of similar materials (see). However, there are exceptions. For example, brass fittings can be used on steel or cast iron pipes They are quite durable and do not deform or corrode. For copper pipes, only copper fittings- the elements of the system are connected by soldering.

Tip: B apartment buildings do not use homemade fittings. Possible hydraulic shocks that can pull even cast-iron plugs out of the batteries.

For private houses or country cottages such a solution is quite acceptable. Homemade primitive fitting is a segment of the usual polypropylene pipe, on which the thread is cut with a die.

This allows you to mount the part without using a soldering iron, like conventional brass threaded fittings. Pressure tests of such systems have shown that they can easily withstand a pressure of 16 atm. But such systems should not be loaded with pressure exceeding 4 atm, which is quite acceptable for a private house or summer cottage.

Connection of polyethylene pipes

High-quality connection of pipelines from PE is carried out in two ways:

  • Detachable. With this connection, the products are crimped with compression fittings, or using steel flanges. To perform the process correctly, there is a specially designed instruction.
  • one-piece. This process is performed by butt welding or socket welding. To connect parts to the pipeline, welded fittings are used, which are called segment, and they consist of separate sections. Welded fittings are used to connect pipes at their branching points. Pipelines with segment fittings are used to transport water, and other liquid and gaseous compositions.

Socket welding is performed with electrofusion fittings, a sample of which can be seen in the photo.

"Electrofusion" technology, which uses electrofusion fittings, the most common welding method polyethylene pipes. Electrofusion couplings are resistant to corrosion, harmful chemical substances, impact-resistant, have a long service life.

How to properly join pipes with an electrofusion fitting, shows the video in this article.

Connection of cast iron and polypropylene pipelines

Polypropylene pipes are great replacement cast iron and steel products in hot water supply systems cold water and heating.

Connections of PP products are performed in two ways:

  • With the use of compression fittings, which allow you to connect PP pipes without welding. Installation is carried out using a crimp and rubber sealing rings, which creates a high tightness of the connection of all nodes.
  • diffuse welding. This is done in a bell or butt, which is more efficient.

Cast iron accessories are made by casting in accordance with the relevant state standards, and are used to connect water and gas pipeline systems. Cast iron units are used in the installation of heating systems, household appliances. Cast-iron elements are connected by socket or socketless methods.

The organization of water supply in a private house begins with the selection of high-quality water pipes, and fittings for internal water supply are selected. Then work with them is carried out, gluing or welding, installation of water supply to ensure high-quality water supply.

Materials for the construction of the plumbing system should be chosen so that it is easier to handle them on your own.

for pipes (couplings, adapters). It is required to connect rigid pipes and elastic hoses, sleeves high pressure and other highways - and different fittings are used for all.
Usually, connecting elements are needed when laying or repairing engineering networks - in places of turns, pipe joints different diameter, branches. It is absolutely impossible to do without such connections during the operation of constantly dismantled structures, in systems with the need for dense overlapping of highways, etc.
The fittings themselves are made from different materials: steel, malleable iron, copper, brass, plastics.

Special titles
Straight fittings (connections of pipes of the same diameter) and transitional fittings (of different diameters) - a code name indicating the characteristics of the connected pipes, and not the design of the connection.
Accordingly, there are special names for fittings of all kinds. So, bends (corners) are designed to correct the direction of the pipe at a certain angle. To branch the line, tees and manifolds are used (if in one direction), or crosses (in different directions). Couplings connect straight pipes (adapters are also straight, but of different diameters). The plugs, respectively, tightly close the end of the pipe, and connect the hoses with fittings.
The design differences of the fittings are due not only to the features of the connection of the mains, but also to the material - there are special connectors for plastic and metal pipes, composite (metal-plastic), high-pressure hoses (HPR).

Fittings for metal pipes
For such lines, welded, crimp, threaded and flanged fittings are used. Connections with cylindrical thread they are sealed with special tapes, threads, etc. Steel and cast iron fittings are used for water and gas pipes, and they must be free of defects (and cast iron fittings with a special thickening at the edges).
Crimp connections for tightness are supplied with sealing rings, they are highly resistant to vibration - they are most in demand in high-pressure systems, for calibrated steel pipes.

Connectors for plastic pipes
Of all types of plastic, polypropylene is mainly used for the manufacture of pipes. They are connected by soldering (local heating), and adapters (threaded) are used at the joints with metal lines. By appointment, fittings for plastic pipes are similar to connectors for metal ones.

Fittings for metal-plastic pipes
Such pipes are joined by compression (with a split ring) collet and press fittings. Threaded adapters are used to connect metal-plastic and metal pipes. Due to reliability, a press connection is popular - crimping the sleeve around the fitting fitting, which requires special tool. And to install a compression fitting, you need two adjustable wrenches.

Fittings for high pressure hoses
Most often, steel fittings are used for elastic lines. Connections for extreme conditions operation must withstand heavy loads and have a protective coating (they are also used and made entirely of corrosion-resistant metals, alloys).
There are several classifications of fittings for high pressure hoses - according to the type of shank, the presence or absence of threads. Most often there are connections with a universal shank (herringbone), less often - especially strong Interlock and reusable repair. Among non-threaded, lock, ring, flange fittings are common. Threaded are classified according to numerous standards.

Fittings are elements of a pipeline system designed to connect a multitude of constituent parts pipelines between themselves, as well as for connecting pipeline fittings, water meters, heat meters and other instrumentation, as well as plumbing equipment in engineering systems Oh for various purposes. The main role of fittings is to provide reliable connection all parts of the pipeline in places of its branches, transitions and turns.

Pipe fittings are divided into straight ones, necessary for connecting pipes of the same diameter, and transition fittings, if pipes of different diameters are used. You can buy fittings for metal pipes, as well as for plastic and metal-plastic pipes. By appointment, the following types of fittings are distinguished:

  • bends and angles designed to change the direction of the pipeline from 45 to 120 degrees;
  • crosses, tees and manifolds are used to branch the pipeline network from the main line;
  • couplings are used to connect identical pipes to each other in a straight section of the pipeline;
  • various adapters (nipple, squeegee, fitting, futorka, etc.) are designed to connect pipes of various diameters, as well as to attach additional equipment;
  • plugs are used to cover the end sections of the pipeline.

Pipe Fittings

Depending on the method of connecting fittings with pipes, there are:

  • threaded fittings designed to connect cast iron and steel pipes, the ends of which are threaded. As a rule, threaded fittings are made of brass, cast iron, steel and copper;
  • capillary solder fittings are used only in systems with copper pipes. This type of connection is the most reliable. The principle of installation - the pipe is covered with a special paste, then the fitting is put on and the joint is heated until the solder melts and fills the entire space between the fitting and the pipe.
  • compression fittings are used in systems with copper and metal-plastic pipes. These fittings are equipped with a ferrule that is tightened special key. As a rule, compression fittings are made of brass, copper, plastic and steel;
  • press fittings are used to connect metal-plastic pipes of open and closed engineering systems, they consist of a body, a seal and a steel crimp sleeve. For the installation of this type of fitting, a special crimping tool is used, thanks to which the connection is reliable and durable.

Buy fittings cheap

To connect a water heated towel rail to a heating or water supply network, special fittings are used. They differ in design, method of attachment to the pipeline and the material used for the manufacture of connecting elements.

Types and purpose of fittings

Depending on the purpose and design nuances, fittings for connecting a heated towel rail are:

    Direct. They fix pipe segments of the same diameter.

    Corner. Such fittings are designed for bends and corners, and allow you to change the direction of the pipes. The adjustable angle is 45°, 90° and 120°.

In addition to the design features important parameter fittings for installing and connecting heated towel rails is a method of attaching pipes and individual elements sanitary equipment. The following types of fittings are on sale:

    flanged;

    welded;

    crimp;

    threaded.

The most popular are inexpensive fittings with threaded connection, which are easy to install and can be easily replaced if damaged with new fixing elements. To ensure the tightness of the attachment points, a sealing tape or a special thread is used.

Features of choice

What fittings and accessories are needed to install a heated towel rail in the bathroom? In order to correctly select and buy the right set of component parts of the connecting elements, you should consider:

    Connection method. Sanitary equipment for drying towels has a different configuration and installation features. For models in the form of a ladder, a diagonal connection is recommended, and for " M-shaped" or " U-shaped" - lateral.

    Manufacturing material. For the production of fittings, brass or stainless steel is usually used, which are then applied protective covering in the form of a layer of chromium. Chrome-plated connecting elements are resistant to corrosion, withstand impact high temperature and are distinguished by an attractive appearance due to the polished surface.
