The heated towel rail is a very convenient device, with which the rapid drying of towels and diverse linen is ensured. After a certain time of operation, the device may come into disrepair or you may have the need to install another product, so you need to know how to change the heated towel rail to save on the services of a professional wizard.
The feature of the installation of the water heated towel rail is that it should crash into the overall water supply system.
Preparing for the disable of the heated towel rail in the bathroom
To correctly change the heated towel rail, it is necessary to prepare to replace accordingly.First of all, you need to choose the right to choose a new bathroom towel rail. The main criterion at this stage is the area of the room.
The larger the size of the bathroom, the greater the knees should have a heated towel rail. An important part of the sewing for the bathroom is the material and diameter of the pipe. The diameter of the pipes of the product and pipes of the water supply highway must coincide. This will allow changing the device faster and easier.
It is necessary to turn off the old heated towel in the bathroom from the water line. This work can be performed both independently and with the help of housing and communal services. In the event of a call for special services, you will have to spend too much time and money, so if you are confident in your abilities, it is more profitable and more advantageous to change the heated towel rail.
Since you have already decided to change the old heated towel in the bathroom, it is better to put a bypass (jumper) and install ball valves. If the jumper is already installed, then you do not have to ask for water supply all over the riser. You simply overlap the ball valve and calmly install a new towel rail in the bathroom.
If you set a towel rail to a new place and the distance to the riser will increase, it is best to install a stainless steel device with a crane of Maevsky. This product is a trigger required to remove air jams from the coil.
When using threadar, consider in advance that the thread will be at a distance from the surface of 6 cm.
The shortcomings are best done until the old heated towel rail is dismantled, because Their cutting is quite a lot of time. To prepare a place to boost or cut the threads under the screwdriver to the transition to the plastic pipe, it is also necessary to destroy the concrete slab in the place where it includes a pipe.
Threaded metal compounds are also packaged, the sealing of which must be performed carefully and carefully, because The repacking of the compound may require re-draining water from the highway, cutting the piece of pipe, etc. The tightness of the compound can be checked only by setting water and feed pressure.

Dismantling of an old heated towel rail
Methods for connecting a water heated towel rail.
Before connecting a new towel in the bathroom, you need to dismantle the old one. First of all, you need to overlap the hot water supply to the pipe to which the old heated towel rail is connected. To do this, you can contact the housing and public utilities or to do it yourself, having previously coordinated with the responsible person.
Side connecting coils and any heated towel rails, which are an integral part of hot water pipes are dismantled by unscrewing threaded connections. In the event that the thread "baked" or the product is simply welded to the pipe, it must be trimmed with a grinder.
In the process of dismantling the old heated towel rail, the trimming should be carried out with the calculation of the pipe area to be sufficient to cut the thread. The heated towel rail is removed from the brackets.

As you know, the correctly installed heated towel rail prevents the formation of condensate on the walls and pipes. In addition, these heating devices also perfectly cope with dampness.
The heated towel rail can be connected to the heating system or the hot water supply system. Connection to the heating system is inappropriate, because In this case, the device will be warm only in the heating season. That is why heated towel rails are most often connected to hot water systems. Water in the pipes is able to quickly destroy the product from the inside, so when buying this equipment, it is necessary to ask the seller, whether the pipes have a corresponding anti-corrosion coating and whether the model visited you for use in Russian conditions has been calculated.
The heated towel rail is attached to the wall using brackets. The most convenient to use adjustable brackets. The eyeliner to the water coil can be hidden (closed in the wall).
Pay attention to such an important characteristic as the location distance of the product. There will be no difficulties if you make overhaul, i.e. Fully change the pipeline and other communications. You just install new pipes and bring a snake to them. However, if you change only a heated towel rail, you need to measure the distance between the discharges and only after that go to the store or market for the new heating device.
The wiring to the bypass is better to do from stainless pipes.

Be sure to note that the diameter of the nozzles of the new device coincides with the diameter of the hot water pipes. If it does not match, you will have to additionally buy special adapters, they are sold in any plumbing store. Experts recommend using for connecting a coil with riser pipes of the so-called. "American" - detachable connections with a cape nut.
To inside the unit, air traffic jams are not formed, it is necessary, as already mentioned, additionally install a special shore valve (Maevsky's crane). It must be installed at the upper point of the heated towel rail. This part allows you to avoid various unpleasant situations that may occur when you first start and further use the equipment.
Do not save on the purchase of ball valves installed on hot water pipes. In addition, you will need to make a jumper (bypass). This jumper is very convenient, because It allows not to overlap water throughout the drain, but only stop the water supply to the heated towel rail. It is necessary, for example, when the laying failed to be replaced. So, with a ball with a ball crane, water will not fall into the heated towel, but the system will circulate in normal mode.
If you purchased a model with a rotary mount, which can be rotated 180 degrees, then when installing, you will need to use rubber gaskets. Be prepared for the fact that such gaskets quickly fail, after which they require urgent replacement. The exit from this situation will be the installation of special rotating brackets - hooks over a heated towel rail. In addition, in the market of modern heating equipment, you can find models with hanging crossbars. Such devices are more preferred.
The procedure for installing a new heated towel rail
Installing the angular connection G 3/4 ".
Connect the device to central heating or hot water supply in parallel highways. If the heated towel rail is designed for less pressure than in the system, its connection is performed through a special gearbox that allows you to adjust the pressure.
First of all, it is necessary to overlap water. If you have the opportunity to do it separately in your apartment, wonderful. Otherwise, it will have to overlap the flow of water throughout the riser, which is necessary to warn the neighbors.
Before installing a serpentker, a jumper is made, which, as already mentioned, is a pipe along which hot water will circulate when overlapping water supply to the heated towel rail. Powerboard to the bypass is made using stainless steel pipes. The jumper is equipped with 3 valves: 2 of them are installed in the place of connection of the coil with a jumper, and the 3rd overlaps the water in the jumper itself.

Next to the heating device you need to fasten the existing brackets (if they are not included with the device, they will have to be purchased separately). The heated towel rail is attached to the place of the future installation. With the help of the pencil, markers are made under the mounting holes. The product must be installed using a construction level, so that at this stage you will need an assistant.
Holes in the wall decorated with tiles are made using a drill with a special drill for a tile. After that, the drill changes to winning and fastening holes are reserved to the desired depth. In the holes, plastic dowels should be inserted, to attach a heated towel to the wall and attach it to it with screws, using a screwdriver or a screwdriver for this.
After that, you will need to attach a coil to the valves on the bypass, using special fittings for this.
If the connection to the heating system or hot water supply is associated with great difficulties or if you periodically turn off the hot water supply, modern electric heated towel rails will solve the problem. Among the indisputable advantages of these devices, you can mark the ease of installation, the ability to regulate the schedule and compactness. Modern models are often equipped with a control panel or daily timer to set the operation mode for a certain time. The power of electrical appliances is different and ranges from 130 to 1000 W. Connecting such devices requires compliance with a number of rules.
Nuances Installation of electrical and combined models
The electric heated towel rail is enough to connect to a normal outlet to 220 V. The specifics of the installation of such devices lies in the mandatory supply of electrical safety, because The bath is a room with high levels of humidity, and water, as you know, perfectly conducts electricity. The socket must be internal type, with a special lid to protect against splashes. It is better if you can hold a wire of the heated towel rail to the outlet in another room. The protective shutdown device is installed.
In the event that the socket and the power cord do not fit into the interior of the room, the supply electrical cable can be hidden in the wall. In this case, the device via a protective shutdown device is connected from the distribution panel. Power cord is dismantled.
The combined heated towel rail is the same water device, but with built-in electric ten. Such alignment allows the device to work from the DHW system or heating, and if necessary, go to work from the electrical network. When installing the heated towel rails of this type, requirements and work are performed both for water and electric models.
