How to connect the heated towel rail

The towel rail is a convenient and useful element of the bathroom. With it, the desired temperature is maintained, you can quickly dry out any thing. The only thing that can cause difficulty is the connection of the heated towel rail.


The towel heater in the bathroom is necessary to maintain the microclimate from the excess moisture of the room.

On sale you can find different models of such devices. The installation is also facilitated by the availability of the necessary connecting parts. It is important to understand their purpose and make the connection yourself.


Towel dryers can be water, electric or combined. The greatest use is for water devices, where the temperature is maintained by hot water. Usually the heated towel heater is connected to a centralized hot water supply system (except for some private buildings where hot water is provided by heating devices).

The device of the heated towel rail

The device of a towel warmer.

Constructively, the heated towel rail is a curved pipe or pipe system. The simplest design is a U-shaped heated towel rail, which has one 180 ° bend over a sufficiently large radius.

A simple M-shaped design, involving three bends and a mutually opposite direction of the pipe after bending, refers to a simple one. A similar design (but with a large number of bends) has a "snake" type model. These structures include one curved pipe.

Towel-type "ladder" is widely used among the proposed standard devices.

It consists of two pipes connected by a bridge and forming a rectangular contour. Inside the circuit, several pipes are connected to them, arranged in parallel. Thus, the form of the ladder is formed. A more complex design implies a checkered appearance.

The method of connection with a hot water supply system is largely determined by the location and size of the supply water pipe. The most common option is when the supply pipe is laid on top of the wall. In this case, a direct tapping into the water supply system is carried out. Sometimes in the bathrooms are made two terminals on the dryer directly from the wall. This gives only one option of connection - the lateral (bending of the ends of the pipe of the heated towel rail towards the wall).

The connection itself can be carried out in parallel or in series. When connected in series, the entire flow of hot water passes through the heated towel rail. With parallel connection, the ends of the dryer tube cut into the passing water pipe at two different points. There is a separation of the flow of water (direct flow through the water pipe and parallel flow through the heated towel rail). By the location of the connection, you can select the bottom horizontal, upper horizontal and side vertical. The lowest connection is considered to be the optimal temperature distribution for the dryer.

Finally, the connection can be directly to the water supply pipe or using additional pipes. They are carried from the main pipe to the location of the desired location of the heated towel rail.

Preparing for installation

Before connecting the coil, it is necessary to prepare the place for its installation. As a rule, there is an old dryer in the bathrooms, which must be dismantled.

If it was fixed on the thread, then the question is solved very simply: with the help of the gas (sanitary) key, the coupling is loosened, the old dryer is removed. If the former dryer is welded to the pipe, then it must be cut using a grinder, and so that the remaining length of the end of the pipe allows threading.

A scheme for the location of the new heated towel rail is made. The marking of the fixing points is made. The brackets on which the dryer is attached are removed from the wall. If this is difficult, they are cut off by the Bulgarian. Ideal case - coincidence of attachment points. Then the brackets are saved. When planning the placement of a new device, the following conditions must be taken into account. The towel heater should not be located more than 2 m from the water supply pipe. The distance from the outer wall covering to the dryer tube depends on the diameter of the pipe: with a diameter of up to 23 mm, the distance must be at least 35 mm, with a diameter of 50 mm - not less than 50 mm (Fig.

The installation of the heated towel rail is only possible after the wall has been finished. Therefore, if necessary, the extraction places are shpatlyuyutsya and restoring the outer covering of the wall. Prior to this, new brackets are installed (if necessary). For this purpose, holes in the wall are made by a perforator or electric drill, brackets are fixed in them.

Reliability of the device depends on how to connect the heated towel rail to the water supply system. For connection it is better to use standard connecting elements. The connection to the main pipe is provided by means of split threaded couplings.

They need to be selected strictly according to the size of the water pipe and the dryer tube. In addition, the couplings are of different designs, so you need to choose the ones that are suitable for the selected towel warmer. When inserting into the pipe, a tee-coupling is required. Connecting with a bend provides a corner adapter.

To ensure that the device is switched on independently, stop valves should be purchased. To eliminate air congestion in the system, it is expedient to install the Mayevsky crane. In addition, when installing the dryer, you can not do without a set of gaskets, as well as compression and nuts.

Connection with a jumper

In order to connect the heated towel rail, it must be connected correctly and reliably to the hot water supply system. If the system maintains a water temperature of 60-70 ° C on average, then it is sufficient to use a serial device connection scheme. However, in order to hedge against accidents, it is better to use a parallel or combined scheme, i.e., allowing if necessary to switch off the dryer and provide a direct flow of water.

A parallel scheme involves inserting directly into a straight pipe or connecting an additional straight section, i.e., jumpers (if the integrity of the water pipe is broken earlier). The combined system provides a stopcock in this additional piece of pipe (Figure 2).

The bridge (bypass) is made of a pipe with a diameter equal to the diameter of the supply water pipe, the length equal to the length of the pipe rupture. Threads are cut at the ends of the bypass. Connection to the water pipe is carried out with the help of a threaded coupling-tee, the free outlet of which is designed to connect the pipe of the heated towel rail. If necessary, the bypass is connected to the pipe via a ball valve.

After mounting the jumper, the heated towel rail is mounted on the brackets and fixed in them. Then a direct connection to the water supply is made. At the inlet end of the dryer a check valve is wound. Then, with the help of connecting fittings (straight or angled adapter), the input and output of the device are connected in a tee with a water pipe and a jumper.

At the same time, the connection of the inlet pipe is carried out through the shut-off valve, which ensures independent activation (deactivation) of the towel dryer. At the other end of the device, the Mayevsky valve is installed via the coupling-tee. The dryer tube is passed through the horizontal holes of the tee, and the Mayevsky valve is mounted on the vertical terminal through the adapter, which is fixed by the union nut.

Special requirements

How to connect a heated towel depends on the risk of flooding the room, the temperature regime, etc. When connecting, you must fulfill a number of mandatory conditions.

First of all, the installation and connection of a new device must take into account the features of laying water pipes and do not create obstacles for the flow of water.

Installing an electric heated towel rail

Installing an electric heated towel rail.

It is forbidden to use pipes with a smaller diameter than the diameter of the supply water pipe in dryers, so as not to create excessive pressure in the dryer. All threaded connections (fittings, couplings, adapters, etc.) should be carried out through gaskets (rubber or fluoroplastic).

The hot water stream in the heated towel rail must be directed from the top down. Adjustment of shut-off valves (especially ball valves) must be carried out smoothly, without effort. Must be provided for the possibility of emergency shutdown of water entering the heated towel rail. Installation of a heated towel rail, if not provided for by the project, must be agreed upon in the appropriate authorities.


To install and connect a heated towel heater you will need:

  • Bulgarian;
  • electric drill;
  • perforator;
  • metal cutter;
  • gas key (sanitary);
  • Adjustable wrench;
  • set of wrenches;
  • screwdriver;
  • pliers;
  • scissors;
