How to connect the new heated towel rail correctly

One of the integral parts of the interior of the modern bath is a heated towel rail. This device in the form of a curved pipe not only allows drying towels and small items of clothing, linen, but also significantly affects the microclimate in the bathroom.


Without a towel in the bathroom can not do, it can dry towels and linen, as well as it significantly affects the microclimate in the bathroom.

How to connect the heated towel rail correctly, so that during operation it performs its functions and does not require additional attention? First of all, we need to determine a suitable place for a fairly large plumbing fixture on the wall. If the towel warmer has already been installed, but you need to replace it, you should pay attention to the way it is connected before you go to the store and choose a model with a bottom or side connection, depending on it. Together with the purchase of the device you need to purchase the necessary tools and a number of materials that will be required during the work.


To subsequently facilitate the repair or replacement of the heated towel rail, it is necessary, when installing it, to mount 2 valves that allow the water to be blocked in case of force majeure circumstances, and a system called bypass. It will allow not to sit without hot water during the repair of the heated towel rail. For this we need the following materials:

Connecting the coil

  • water stop valves (cranes) - 3 pcs .;
  • tee - 2 pieces;
  • short pipe sections for bypass;
  • fittings (adapters) straight or angled;
  • полотенчушитель;
  • sealant;
  • a Bulgarian or a hand hacksaw for metal;
  • lorka (plate) corresponding to the pipe diameter;
  • gas wrench.

The towel can be connected in two different ways:

  • in the heating system;
  • to pipes of hot water supply.

The first method is suitable for private households with autonomous heating. In a multi-storey city house, the side of the heating system can only be inspected with the permission of the housing administration or the relevant organization. It should be taken into account that such a device will function only during the winter season. Therefore, they often resort to the second method and connect towel warmers to the hot water pipe.

When replacing the coil in an apartment of old construction, one must take into account that the connection for the chosen model must necessarily be lower. This is dictated by the features of communications in these apartments. If there is a big repair in the bathroom and the pipes are mounted in the wall, then the model with a side connection (figure 1) will do. The main requirement for installation in this case will be a careful isolation of the connections to avoid leaks, the elimination of which will require violation of the integrity of the wall covering.

Mounting options

Options for connecting the heated towel rail.

Before buying a new heated towel rail, be sure to measure the distance between the ends of the pipe to which the equipment will be attached and select only the model corresponding to this size. This will help to avoid mistakes and save time on their elimination.

The diameter of the nozzles of the new device must correspond to or be less than the diameter of the pipe to which the connection is made. If the diameter of the towel heater's outlets is greater than the diameter of the pipe, the water pressure will be constantly increased in it, which will soon lead to a leak. With a difference in diameter, the device must be connected using adapters.

Stages of connection

Before you connect the heated towel rail, you need to visit the housing office or contact another responsible person in your home or place to live and coordinate with him the shutdown of hot water for the time of the alteration. During the shutdown you have to do a lot:

  • dismantle the old device;
  • install bypass and taps;
  • mount a new coil (or ladder);
  • visually check the installation quality.

After the water supply has been renewed, leaks on the connections of the device can be eliminated by closing the valves and bypassing. But the connections on the bypass itself must be faultless, otherwise a new shutdown of hot water in the system will be required.

Remove the old device in the following order:

  1. Turn off hot water supply. In a private house, no approval is required, but this step is mandatory in any case.
  2. If the heated towel rail was installed using a threaded connection, unscrew the nuts on the pipes with a gas wrench.
  3. A whole pipe or too old threaded joints can be cut off with a bulgarian or metal hacksaw. Remove the old coil. The length of the remaining lengths of the pipe must be sufficient to cut a new thread.

After dismantling, a new thread is cut on the pipe remnants with the help of a die (die), and it is possible to update the old thread, if any. In accordance with the scheme (Fig. 2), installation of tees, a tap and bypass pipes is carried out.

All threaded connections must be carefully insulated with sealant, FUM tape or a special thread.

The next step is to connect the heated towel rail. Depending on the type of connection (bottom or side), pipes are installed in series on the pipes (one for each branch), fittings and serpentine of the heated towel rail. All connections must also be sealed. When using the sealant, allow it to set for about 1 hour. After this, bring the valves at the inlet and outlet of the coil to the "open" position, and close the bypass valve. Make water connections, check for leaks at connection points.

The replacement of the heated towel rail is completed and it should start to heat up if everything is done correctly and its taps are open. Hot water must flow into all the cranes of the apartment, which are installed after the towel warmer, without obstacles.
