Why does not the heated towel rail in the bathroom

Cold and damp walls in the bathroom create discomfort and a deterioration in the appearance of the room. This happens when the heated towel rail stops working. It is associated with hot water supply and creates the necessary microclimate in the room. When the landlord begins to understand why the heated towel rail is cold, his unskilled interference with the work of a hot water supply can lead to an accident, for which you have to answer, therefore, it is necessary to approach this issue with all responsibility.

To answer the question why the heated towel rail in the bathroom does not heat up and solve the problem, you should first deal with the scheme for supplying hot water through it. Options heated towel rail (PS) may be different. In new houses, they are supplied with water from the same risers as for hot water supply. In the secondary housing stock, towel warmers are connected for the most part to a separate recirculation circuit for hot water supply or operate from a central heating system.

The reasons for the cooling of the heated towel rail

The heated towel rail may cool or not heat up at all for various reasons. Let's consider each of them separately.

Water system device

The water supply system can be either circulating or dead-end. In the first case, hot water enters through the supply riser, and leaves through the return. In this case, the pipes always remain hot. In a dead-end system, the temperature in the heated towel rail depends on water consumption: if the taps are closed, it starts to cool. This usually happens at night when water consumption drops sharply. In this case, the landlord can integrate the substation into the heating system, but then in the warm season it will be turned off.

Another option is to install a combined device, when along with water heating there is also an electric one. The energy consumption here will be small, since the cooling of the pipes does not occur so often.

Pipe clogging

Often the heated towel rail in the bathroom remains cold due to the formation of clogging and plugs in the pipes, which is associated with the low quality of the water coolant containing impurities of salts and mechanical particles. To clean them, the area is overlapped and cleaned with a soft wire ruff. Salt deposits form strong joints with the inner surface of the pipes, and they will have to be tapped by washing with water. Solid precipitates are removed with a solution of hydrochloric acid.

Outdated pipes in the water system can also clog. At the same time, water consumption is reduced, and it may not enter the heated towel rail because of the high resistance. Cleaning of these pipes is carried out by specialists from the housing office. They should be asked to restore normal circulation.

Airiness

The reason why the heated towel rail installed in the bathroom is not warming can be the formation of an air jam. After the installation and commissioning of the new device, air may remain in it, which prevents the passage of hot water, which is removed using the installed air vent valve.

If the heated towel rail is connected to the heating system, air can collect in any other place. It will require comprehensive measures to remove air congestion from the entire circuit. To do this, air vents on each battery are opened in turn, starting with the boiler or input line. Under the pressure of the water stream, the air itself enters the outlet.

The design and features of connecting a heated towel rail

The reasons for the cooling of PS can be in its design. If a heated towel rail it is connected from below and at the same time it is significantly elongated in height, pressure may not be enough for water to go up to the heat exchanger. This usually applies to handicraft devices. Factory-made models are balanced and should work reliably.

The nozzles to the PS are most often smaller in diameter, but usually only one step. Then hot water easily overcomes resistance and normal circulation occurs. If the diameter of the nozzle is too small, the liquid will go along the path of least resistance, i.e. past the contour with a heated towel rail.

Important! Periodically check the functionality of the towel rail shutoff valves, due to a malfunction of which the water supply may be shut off.

Other reasons

If all of the above measures are taken, and the PS did not start to warm up, you need to look for reasons outside of your apartment. They may be as follows:

1. When replacing the heated towel rail, the neighbors changed the connection diagram and blocked the riser.
2. Switching to summer mode and turning off the heating system.
3. The diameters of the bends from the riser to the PS are selected incorrectly.

A feature of the use of a heated towel rail is the need to circulate water through it through the return flow of the DHW system. The circuit of the highway passes through several apartments, and there should not be any obstacles to the water.

A bad example of interference with a circuit is the unauthorized removal of drying. As a result of this, the water circulation stops and the remaining PSs cool down. The circulation must be restored bypassing this apartment. This requires that a bypass with ball valves be installed or a jumper must be connected instead of the heated towel rail through which circulation must take place. Bypass is needed in any case, since the seals through which the PS is connected to the pipes wear out over time and require replacement.

If the drying in the apartment is not heated due to the fault of the neighbors, you need to write a statement to the operating company in the prescribed form, not paying attention to the assurances that they are all right. Also, the ZhEK itself can change the water supply scheme, because of which the return in the domestic hot water system is turned off and the heated towel rails stop working not only in one, but in several apartments at once. The housing office is obliged to take note of the complaint and restore the normal operation of the circuit.

Faulty electric towel warmers

In addition to the water substation installed under the project, there is an electric one, which the owner of the apartment can install on his own. Towel dryers can be combined, with a choice of heating method: either water or electricity. Such a device has become the most popular at the present time, since it does not depend on interruptions in water supply.

Electric PS can be installed separately. Towel dryer samples:

• cable;
• based on heating elements.

Cable constructions are completely replaced upon failure. The second type of heated towel rail can be repaired, because it works by heating the heat transfer fluid with a heating element located at the bottom of the device. There, water or antifreeze is heated and gives off heat to the metal pipe.

The electric heated towel rail stops heating for the following reasons:

• burnout of the heater due to the lack of fluid in the system;
• running out of heater life;
• loss of electrical contact;
• malfunction of the temperature controller or timer.

It is easy to replace TEN with a new one by screwing it into a heat exchanger. Maintenance of the electrical substation must be done in accordance with the attached instructions. The reason for its shutdown may be hidden in improper setup and operation, for example, when the thermostat is set to the “off” position.

Important! Electrical PS installation and sockets for its connection must be made in accordance with all electrical safety rules. All electrical equipment in the bathroom is connected via an RCD with a trip current of no higher than 10 mA.

Conclusion

The water heated towel rail in the bathroom is not heated for the following main reasons: cessation of fluid circulation, clogged pipes, air congestion in the system, incorrect wiring diagram, installation of a makeshift device production. Simple malfunctions are resolved independently, and in case of failure, you should seek the help of specialists.
