Connecting a heated towel rail to a hot water riser: diagram

Connecting a heated towel rail in the bathroom is necessary to ensure quick drying of small items, as well as maintaining the required level of heat in the bathroom. Instead of simple curved pipes, elegant designs with a spectacular design are now installed. They can be seen in numerous photos and videos on the Internet. Previously, horizontal designs in the form of coils prevailed, but now vertical ones have come into fashion - a ladder with jumpers.

Options for connecting a heated towel rail

Towel dryers must function continuously to create the optimal microclimate in the bathroom. For their installation, you can invite experts or install a heated towel rail with your own hands. How to connect a heated towel rail?

1. To the hot water system.
2. To the heating system.
3. To the electric heater.
4. Combined connection method.

The first method is most common, since hot water is supplied year-round. Heating systems only work in the cold season, and this is not entirely convenient. In addition, repair and replacement of a heated towel rail in winter requires a shutdown of the riser, which can lead to its freezing. The output may be the installation of a bypass bypass. Connecting the device to the heating system requires the use of seamless pipes that withstand water shocks.

Electric heated models provide a system independent of hot water. The disadvantage is the cost of electricity consumption. When deciding how to install a heated towel rail in the bathroom, some owners choose the combined option when you can selectively use water or electric heating. The method is especially convenient with frequent shutdowns of the water supply. Such a modification is more expensive than analogues, but over time it pays off due to increased comfort. In this case, cyclic operation does not lead to a significant consumption of electricity.

Features of installing a heated towel rail

Before starting the installation, you need to consider some important points:

• In a multi-storey building, the installation of a device connected to a centralized hot water supply (DHW) system has its own characteristics. Incorrect connection of the heated towel rail to the riser can create problems in the whole entrance.
• Choosing a spectacular imported heated towel rail, you should find out whether it is possible to connect to the domestic hot water system. Usually, domestic production models made according to GOST and corresponding SNiP are recommended.

In pursuit of fashion, apartment owners use devices with parts made of dissimilar metals, which leads to electrochemical corrosion. Now widely used plastic pipesconnected to devices from any metals.

• To connect a heated towel rail to the apartment heating system, it is recommended to choose a combined type of product.

• It is not recommended to install a heated towel rail in the bathroom with a bottom connection: its capacity is reduced by 10%. It is recommended to connect devices of the "step ladder" type diagonally, with lateral or vertical connection to the water supply. The center distance is 500 mm.
• The heated towel rail is selected exactly according to the size and geometry of the pipe layout.
• For pipes of different diameters, adapters are used at the connection points. It is not allowed to use pipes with a diameter smaller than in the system on the device. In places of narrowing, the pressure rises, which can lead to an accident.
• Installation of a heated towel rail to a riser of hot water is carried out using bends, detachable pipe joints and taps. It should be borne in mind that they do not regulate the flow of water and must be open or closed completely. If a change in fluid flow rate is required, you can replace one towel rail faucet with an adjustable valve containing a valve with a seat.

At the junction of the pipes, a bypass is equipped - a jumper that allows you to turn off any device without blocking the water supply through the riser. It is not necessary to install a bypass, but it can be very useful for repair work when there are problems with blocking the water in the pipe.

DIY installation of a water heated towel rail

To install a new device, first of all, a heated towel rail connection diagram is required indicating the dimensions of each section and the location of the fittings, then the assembly will be more accurate.

Do-it-yourself installation of a heated towel rail in the bathroom now requires a soldering iron for plastic pipe welding. The kit should have nozzles of standard sizes. If you follow all the instructions correctly, the welding process is easy to master on your own. It’s useful to watch a training video on this topic in order not to miss important points of the technology.

You can extend the pipes to any place where the device will be installed. Do not just hang a heated towel rail over the bathroom. There are several reasons for this:

1. Dryers are never placed where there is excess moisture.
2. The ingress of water on hot pipes will provoke increased humidity and the precipitation of calcium salts on them.
3. Uncomfortable to take a shower and reach for things on the pipes through the bath.

Pipe preparation

Progress will be as follows:

• Pieces of plastic pipes of the required size are cut with a pipe cutter. At the ends, a chamfer with a slope of 150 and a length of 2-3 mm is removed. Burrs and crumbs are removed from the cut edges to produce quality joints.
• It is necessary to shut off the valve for supplying hot water to the riser and cut off the old heated towel rail from the pipes.

Important! The issue of installing the device should first be agreed with the Housing Office.

• The riser can be worn out, then it is advisable to replace it partially or put a whole new one. It is advisable not to leave the old pipes in the ceilings, and the connection points of the new ones should be available for repair. The work of replacing the riser and installing bends from it should be entrusted to specialists.
• The next step is the installation of ball valves and bypass - a section of the pipeline with fittings.

Fixing the heated towel rail to the wall

How to hang a heated towel rail in the bathroom? For this, brackets are used. First they are screwed to the device, then they are aligned with a level and marks are made on the wall.

In the bathroom you have to drill holes in the tiles, for which a special drill is used. Fix the device to the wall with plastic dowels.

It is important to decide at what height the heated towel rail should be hung, and choose the right clearance. The distance from the wall to the axis of the towel rail pipe is normal:

• from 5 to 5.5 cm with a diameter of up to 2 ″;
• 3.5 cm in diameter up to 1 ″.

The fastening can be fixed or with an adjustable gap due to the stud screwed into the bracket. So you can create the necessary air circulation, providing quick drying of linen. It is not recommended to set up too often because the pipes are constantly under pressure. They work reliably when constantly fixed.

The device should not be fixed rigidly, so that when the pipe deforms thermally, the load-bearing sections of the wall are not loaded.

How to install a heated towel rail for ease of use? The standard provides that the height of the heated towel rail according to the rules is 120 cm. If the size cannot be maintained, the permissible lower limit is 95 cm, and the upper limit is 170 cm.

Before connecting the heated towel rail, you should choose suitable fittings. The thread is sealed by winding from flax, and the tightening is done carefully so as not to damage the threaded connections.

Pipe connection

Polypropylene pipes are welded to the couplings with a soldering iron. The pipes of the required length are cut. At the ends, the chamfer is removed and the edges are cleaned. The pipe is inserted into the sleeve, and the coupling is mounted on the pin, after which they are heated. Warm-up time is determined by the table.

Additional control: an element is considered heated if it can be easily turned and removed from the nozzle.

After removing from the soldering iron, the heated parts are immediately connected. They are positioned exactly relative to each other with a slight pressure. After 3-5 seconds, the pipe joint sets.

Mount the device so that water passes through it from top to bottom. To do this, the water heated towel rail is first connected to the riser by the upper inlet socket. By connecting and fixing the device, the system is checked for leaks, for which they open the taps and turn on the hot water supply. Installed devices should not have leaks.

Conclusion

Installation of a heated towel rail in the bathroom is a complex list of operations that affect the reliability of the device in the future. High-quality installation is usually carried out by specialists, but with the skills to work with water supply, it is possible to install a heated towel rail with your own hands.
