Air locks
The most common cause of violations in heating is air pockets, which are formed due to leakage, rapid filling of the system or as a result of heating water. Especially often they appear in the apartments of the upper floors.
In order for cold radiators to become hot, you need to remove air from the system. Modern models are equipped with special exhaust valves located at the top of the batteries, which operate automatically. Also, a Mayevsky valve or a drain valve can be installed on the radiators, with the help of which the air is removed manually.
The Mayevsky crane is a cone-shaped threaded rod, when unscrewed, a through hole opens and the gas medium is removed from the coolant.
What to do if the heated towel rail is cold
Today, an indispensable household appliance in the bathroom is a heated towel rail, thanks to which, after water procedures, each person can use clean, warm and dry towels.
However, like all household appliances, a heated towel rail may not work.
The question arises: why is the heated towel rail cold? How to fix this problem, fix the breakage, prevent the formation of fungus on wet tissues?
What is a towel dryer?
Those who are not familiar with a heated towel rail may confuse it with the outer part of a heating or communication system. In fact, this device is nothing more than heating equipment that is installed in the bathroom and mounted against a free wall.
There are two types of heated towel rails:
- Water - a curved pipe inside which hot water circulates;
- Electrical - appliances that are in the shape of a rectangle, lattice or curved pipes and are installed near sockets. Often, experts recommend buying devices with a moisture protection function.
All heated towel rails have a different nature of heating, and therefore the service life of the equipment depends on the correct choice of them. To choose a reliable and safe heated towel rail, you need to consider a few basic recommendations:
- Availability of a passport and a warranty card indicating the manufacturer's data;
- Availability of a hygiene card;
- Correct appearance: the back side of high-quality devices is always smooth, there are no scratches, coating defects.
- Complete set (if it is an electric device): heated towel rail, fasteners, power cord.
If the price of a heated towel rail of one brand is underestimated, and in a similar model the cost is an order of magnitude higher, it is necessary to clarify the main differences.
Why is the heated towel rail cold: causes of failure
If you wondered why the heated towel rail is cold, then your appliance has broken down and needs to be repaired. However, before proceeding to the technical part, it is worth studying the reasons for the failure of the device.
Let's consider the main ones:
- Failure in the supply of water or electricity. Frequent power surges can damage the essential components of the heated towel rail. Or, due to water vapor, condensation has formed and the outlet has stopped working.
- A blockage in the supply to the appliance, which may be due to the low temperature in the bathroom.
- Insufficient fluid circulation caused by weak water pressure.
- The presence of plaque on the towel warmer fans.
- Airlock.
These are the most common reasons for the breakdown of a household heated towel rail.
How to fix a cold heated towel rail?
Once you have correctly identified the root cause of a cold towel warmer, you can begin troubleshooting.However, it is worth noting that each breakdown has its own solution methods.
The problem of blockage of an electrical appliance and its solution
It is necessary to turn off the water and electricity from the device and remove it from the wall. We unscrew the valve and clean the passage well with a metal wire. After performing this operation, it is necessary to clean the section of the pipe, which is located at the beginning of the dryer. Next, you can install the heated towel rail in place and check the quality of its work.
It is worth noting that another method of removing blockages in the heated towel rail is the use of concentrated hydrochloric acid. The liquid is poured into the pipes and allowed time for filtration and purification.
Clogged water heater and how to solve it
We turn off the water to the device, remove the heated towel rail from the wall. We unscrew the futorka, turn the device over and pour out all the water. We clean all areas of water drying with a thick metal cable. Then, under the pressure of water, we wash the device from debris and metal particles.
Air lock and its elimination
In order to eliminate the air lock, it is necessary to release air from the device. To do this, you need to partially dismantle the heated towel rail, since the valve with the air release bolt is usually located on the back wall of the dryer.
We take a flat screwdriver, tighten the bolt half a turn so that the air from the pipe can come out. If water begins to come out of the hole, then the plug has been removed. We twist the bolt back and check the operation of the heated towel rail.
To eliminate all other problems, you need to call a specialist, as you can damage the structure by incorrect actions. Therefore, if you are interested in the stable operation of your device, choose the right troubleshooting methods.
How to get rid of condensation on pipes
You need to start with the simplest - remove sources of high humidity in a particular room where condensation constantly occurs.
Avoid active evaporation when boiling water (use tight-fitting lids). If you do only this, then there will be much less reasons for the occurrence of condensate. For example, do not hang wet (washed) linen next to a ventilation or water pipe.
In the event that the usual precautions do not give positive results, it is necessary to come to grips with ventilation. In apartment buildings, it is provided for by the house construction project - ventilation shafts and pipes are laid
If there is not enough draft (there is no air movement) in the ventilation pipe (duct), then the communication is blocked (clogged) by some object, or simply by accumulated dust and it needs to be cleaned.
For complete confidence in the operability of the ventilation system, it is necessary to install fans specially designed to forcefully influence the movement of air flows.
For private houses, if there is no ventilation system for rooms with unforeseen high humidity. will have to install it.
Without such an addition, the humidity will remain at the same level.
Regarding stove and ventilation pipes. on which condensed moisture may also form, it is necessary to bring them into a working condition corresponding to the correct performance of their working functions.
So for a chimney (chimney), the temperature of the smoke passing through it is very important. If it is not high enough, moisture will form and accumulate, which will lead to the need to repair or replace the entire smoke extraction system.
That is, so that condensate does not occur, it is necessary to make the stove such that the temperature of the smoke coming out of it is high enough (230 degrees or more).
For ventilation systems, the opposite is true. There should already be enough cooled air. For this, kitchen hoods are installed directly above the stove.
They not only capture the smells of cooking food (many believe that this is their purpose), but, due to their large surface, they effectively take away the heat that the stove or oven gives.
What to do if condensation appears on the pipes of cold water supply?
There are times when everything is in order with ventilation, but in a room, for example, in a bathroom, a large temperature difference periodically occurs between the pipes and their environment.
This happens when there are lovers in the house to take a very hot shower. In this case, a large amount of steam is formed, which, in contact with the pipes, falls on them in the form of condensate.
This phenomenon can be overcome in only one way - to use heat-insulating materials. which it is necessary to close the pipes from contact with the environment.
There are several options for sale:
- mineral wool mats with an external coating of aluminum foil;
- tubes made of porous materials (rubber, polystyrene, polystyrene).
In the first case, the problematic pipe is wrapped with this material, followed by fixation. In the second, the tubes are cut lengthwise and put on a weeping pipe.
Their inner diameter is easy to choose for the desired section, as this is provided by manufacturers and almost all standard sizes are on sale.
Old methods of dealing with condensate, such as moisture-absorbing bags (silica gel), which are sent to dry as they get wet, or gauze with the free end lowered into a jar to collect water, are vitally outdated. They can only be used as a temporary solution to the problem.
The consequences of high humidity
Condensation is facilitated by high ambient humidity
The main reason that contributes to condensation is the increased humidity of the environment. That is why this process is typical for toilets and bathrooms, basements, boiler rooms, laundries, etc.
Surfaces damaged by condensation have an ugly appearance. In addition, its appearance carries other dangers. One of them is corrosion, which eventually destroys metal structures. And yet, constant humidity is very fond of mold fungus, which causes allergic and respiratory diseases. Both cannot be called something pleasant and useful.
Clogged heating system
The last battery is too long.
Why is one battery hot and the other cold. Experts call the following reasons for the occurrence of such a situation:
- airing the system;
- low quality of the coolant;
- low quality heating element.
Airing the system. Air can accumulate in individual elements of the heating system. This phenomenon is called circuit airing.
Air can get into the wiring:
- from an open expansion tank;
- if ordinary, tap water was used as a heat carrier. It contains a certain percentage of dissolved air;
- the aggressive medium of the coolant oxidizes the walls of aluminum radiators. As a result, oxygen is released. It accumulates inside, forming a cork.
It is easy to determine if there is an air lock inside the heating equipment. To do this, you need to turn off the taps on the supply pipe and the return pipe at the same time, and then open them in complete silence. If at the time of opening the tap inside the device there are extraneous noises and gurgling, there is an air lock. It is she who is the main reason why one battery is cold, the rest are hot.
Batteries are often cold due to deposits on the inner walls of the case. The reason for their appearance are various impurities in the composition of the coolant and the products of the interaction of hot water and metal. What to do in this case?
Radiators are cleaned in an apartment in several ways, each of which requires certain equipment and performance conditions.
If the battery is equipped with taps at the inlet and outlet of the coolant, then it can be washed even when the heating is running.To do this, the radiator is removed and the dirt is washed off with a strong jet of water. In case of failure, the sediment from the walls of the housing is removed using chemicals. After drying, the heater is installed in its place, and the joints are carefully sealed.
It is possible to remove deposits from the walls of the batteries without removing them. This is done using special equipment, using the following methods:
- Chemical. It is carried out using solutions of organic and mineral acids, alkali and other compounds. It is produced using special equipment, consisting of a pump, a container for cleaning fluid and hoses. The method is indispensable for steel pipes.
- Hydropneumatic. Used with equipment that can generate high pressure. Water is used as a cleaning fluid, due to which turbulent flows are formed that destroy deposits on the walls of pipes and radiators.
- Hydrodynamic. It is carried out with a jet of water under high pressure, the supply of liquid to hard-to-reach places is provided by various nozzles. The cleaning method is effective for cast iron heating elements and is expensive.
- Pneumohydropulse. It is used for batteries and pipes, the diameter of which is not more than 150 mm. Deposits are removed using a water pneumogun, which can act pointwise.
Why do droplets appear on the pipes in the toilet
This usually happens due to the difference in temperature between the surface of the pipeline and the air in the room. And if there is no ventilation in the room or it does not work well, then mini-drops are necessarily formed. Pipes also sweat due to high humidity in the room. Water actively settles on the risers of the pipeline, which conduct cold water. Each room has its own reasons for the formation of drops. Wet pipes in the bathroom become due to poor ventilation.
To understand that this is the case at home, try the following:
- Leave the toilet doors unlocked at night;
- If in the morning you find absolutely dry pipes, then something needs to be done to eliminate problems with the ventilation system.
Water droplets on the pipe may appear due to the fact that the temperature of the pipe differs from the temperature inside the room
Systematic leakage of water from the tank also provokes condensation. This problem is easy to solve by checking the health of the toilet and repairing the release valve and the faucet at the tank. Condensation also forms if the pipe leaks.
What to do if the bottom of the battery is colder than the top
This problem is solved in two ways. You can remove the air lock using a Mayevsky crane or a bleeder. First of all, shut off the coolant supply to the radiator and leave the return line open. Open the bleeder, wait for the air to escape, close the bleeder and open the coolant supply. As a rule, this is enough.
In the event that this method did not work, and we are talking about an apartment building, it is better to call a specialist. For private houses, there is another option. First you need to turn off the heating supply, open the drain at the highest point of the system and squeeze out all the air with back pressure.
Each heating system can have its own characteristics, and therefore there is a high probability of atypical problems. These include incorrectly selected pipe diameters, incorrect distribution of the coolant, poor throughput, lack of pressure, malfunctions of the circulation pump or expansion tank.
If, with the onset of cold weather and the heating season, heating was given to your house, and the batteries do not work, then the problem may be a technical malfunction or the functioning of the entire supply system.

And here it is important to understand the main causes and individual problems that will need to be eliminated in order for the batteries to give off the maximum amount of heat.Tip: if you called a plumber to your house, check if only one battery is cold, or if a similar problem has occurred in the entire apartment, riser or porch
To do this, interview neighbors so that it is easier for a specialist to determine the possible cause of problems and quickly repair the system.

To do this, interview your neighbors so that it is easier for a specialist to determine the possible cause of problems and repair the system faster.
We can identify the main factors in which the batteries remain cold:
- the presence of air pockets in the heating system;
- technical blockage of a single battery;
- incorrect connection of each of the elements and the entire system as a whole.
Let's consider each reason separately.
The heated towel rail has become cold, the heated towel rail in the bathroom does not work
It is very nice when you come to a cozy bathroom, take a shower and take a warm towel from the heated towel rail. But sometimes with this device there are problems that can spoil any impression of going to the shower. To answer the question why the heated towel rail became cold, the professionals of the Plumber Service company will help.
What is a good towel warmer
This heater is designed for installation in bathrooms and is responsible for drying and heating large and small towels. Therefore, when the heated towel rail does not heat, the comfort of the bathroom is out of the question.
In addition to towels, on this device it is convenient to dry and heat small items and linen to a comfortable temperature. It can also be used as a compensating loop, and this will not be the reason why the heated towel rail does not heat up.
With the onset of a cold winter, another useful function appears - additional heating. Therefore, if the heated towel rail is cold in cold weather, although there is hot water, staying in the bathroom may seem less comfortable.
A wide range of heated towel rails is divided into the following categories:
- water;
- electrical.
The first category is made in the form of a curved pipe with constantly circulating water. And electrical appliances are suitable not only for the bathroom, but also for any premises. The only condition is the presence of an outlet.
When making a purchase, no one will give you a guarantee, and the situation when the heated towel rail in the bathroom does not heat up can happen at any time. But unlike manufacturers, you can get a guaranteed quality of work from the specialists of the Plumber Service. Workers with a high skill level will not only answer the question why the heated towel rail is cold, but also solve it with ease.
Reasons for failure
A plumber with experience, before repairing or replacing, will definitely deal with the cause. This will help to avoid re-breakdown and save money. But before answering the question why the heated towel rail in the bathroom does not heat, the worker must determine its type.
It is logical that the electrical device does not work due to problems with the supply of electricity. When the heated towel rail does not heat up, it is difficult to decide what to do yourself. And experts know that high humidity, water and steam ingress form condensation that harms the outlet. In this case, the specialist recommends using for the bathroom, models made in a moisture-resistant version.
Checking the health of the outlet, presumably because of which the heated towel rail does not heat, is carried out using an extension cord. Other causes of malfunction may be possible blockages and breakdowns of the electrical part.
It is worth considering that if a heated towel rail does not work in the house, you cannot do without a master. An inexperienced person in this area can simply break the device or harm their health.
An indicator of a blockage in a faucet or pipe is that the heated towel rail is not heating and there is no water circulation.
Oddly enough, the pipeline in the neighboring apartment can also cause inconvenience.If it is not replaced correctly, the main flow starts in the opposite direction to that required.
When the heated towel rail in the bathroom does not work, the specialists of the Plumber Service company know what to do. If the established cause of poor heating is in an airlock, the master will immediately begin repairs.
The repair option depends on the type of device, namely:
- If the cold heated towel rail is of electric type, then it is necessary to turn it off and dismantle it. Next, the plumber unscrews the valve and cleans the possible blockage and mounts the device back. Now that the electric heated towel rail does not heat up, you know that calling the special service at 8 (495) 152-21-22 will solve the problem.
- If there is a blockage in the water version, it must be dismantled, and the remaining water is removed. Having removed the cold towel warmer, the plumber already knows what to do next. Armed with a thick metal cable, all areas of the dryer are thoroughly cleaned. To finally remove all the debris, the structure is shaken and washed with a powerful jet of water. In the case when there is no circulation at all in the heated towel rail, this manipulation is repeated more than once.
From all of the above, it is clear that this addition to the interior can have many causes of breakdowns. And when the heated towel rail fails or cools down, only the plumber knows what to do to fix the problem. Since each type of breakdown requires an individual approach and experience.
