An electric heated towel rail is a device used for quick and comfortable drying of towels. In addition, in the bathroom it can also be used as a heating device. Before purchasing such equipment, it is recommended to find out how many watts an electric heated towel rail consumes and which model is best to choose.
Are there GOST standards regulating energy consumption of equipment?
According to GOST R 51617-2000, during the heating season the temperature in the bathroom should be +25°C. If the room is small, then a heated towel rail with an electric water heater can handle its heating. When choosing it, it is necessary to take into account that the power corresponds to the area of the heated room.
In order for this device to heat a room, a minimum of 100 W is needed per 1 m². Taking into account the fact that the equipment should not work to wear out, i.e. at its maximum capabilities, it is recommended to take its power into account with a reserve. 140 W per 1 m² is considered optimal.
In this case, the device will be able to heat the bathroom well, while the electricity consumption will be small.
Why do you need a thermostat?
Manufacturers of heated towel rails today offer several model options: from simple budget ones to those equipped with additional options for more convenient operation and saving energy consumption. The simplest option is when the unit operates at a constant temperature, that is, it heats up stably and operates in the same temperature range.
More structurally complex heated towel rails are equipped with special sensors that, when a certain temperature is reached, switch the devices into an energy-saving mode. Models of this type are quite expensive.
Complete set of electric heated towel rail with thermostat
An alternative option is an electric heated towel rail with a thermostat, which allows the user to independently set the temperature range. If you urgently need to dry your laundry or the room gets cold, you just need to set the device to maximum.
The rest of the time, the equipment will operate at minimum power, thereby significantly saving energy. An electric model with a thermostat will generally cost 5-10% more than a simple standard electric heated towel rail without additional options, but the difference in price will quickly pay for itself in ongoing savings on electricity bills.
Design features of electric dryers
The design of a modern heated towel rail will depend on the type of heating mechanism used in it. Depending on this, such equipment is:
- liquid;
- dry;
- hybrid.
Any electric heated towel rail consists of a body, a heating element and a power cord. In the liquid version, great importance is given to sealing the housing, because There is a coolant inside (oil or antifreeze). If heating occurs due to the cable, then it is placed in a graphite gasket.
The best option is a 2-circuit design. Here, one circuit of the device is powered by electricity, and the second by a hot water supply system. During the heating season, the heated towel rail operates using hot water supply, and in the warm season - from the mains.
Constructions
All heated towel rails can be divided into three large groups:
- classic shape;
- ladder;
- designer
An electric heated towel rail with a classic shape - not too complex designs such as C-shaped, U- and M-shaped, S-shaped, snake or zigzag. Such forms appeared first; they were made by bending the riser pipe. Modern designers combine them to create interesting models. But even the simplest in shape - just racks of one or two pipes - look very non-trivial in a suitable interior.
Even traditional shapes can be interesting
Ladders are a more complex design of heated towel rails. They consist of one or more racks, which are connected by a number of jumpers. The jumpers can be hollow inside (tubes), a cable can be laid in them, and coolant (water, oil) can flow. But they are also made simply from metal plates - increasing the heat transfer area.
You can always find something interesting
Designer models of electric heated towel rails can be very unusual. Some build a mirror into them, some make them in the form of a variety of shapes. You can even find them in the form of animals, fish, flowers. This is primarily a decoration. It is unlikely that you will dry your clothes on such a device.
What affects electricity consumption
The energy consumption of a heated towel rail mainly depends on the type of heating element used. In addition, the dimensions of the device are also important; the larger they are, the more powerful the equipment and the more electricity it consumes.
The thermal cord ensures rapid heating of the device and consumes less energy, but after disconnecting from the network, the heated towel rail quickly cools down. The heating element has more power, therefore the energy consumption is higher. The device takes a long time to heat up, but after switching off it retains heat well.
It is also important that the device contains a thermostat, which allows you to set the required heating temperature, as well as a timer, with which you can set the operating mode.
Device with heating element
Depending on the model, the power of the heating element or insulated heating cable ranges from 300 W to 2 kW. Such devices use a coolant liquid:
- distilled water;
- antifreeze;
- mineral oil.
The last option provides maximum heat capacity; such heated towel rails heat up more slowly, but take a long time to cool down. The type and volume of coolant matter. This indicator directly affects the characteristics of the device.
The installation of such a device is carried out so that the heating element is at the bottom. Switching on and off the equipment is controlled by thermal sensors, so the main energy consumption occurs during warm-up. After this, the set temperature is only maintained, so electricity consumption is small.
Heated towel rail with cable
The principle of operation of such equipment is similar to how a “warm floor” works. A heating cable placed in a graphite sheath is installed inside the body of the heated towel rail, and when current passes through it, the device heats up. Thanks to this, almost instantaneous heating of the entire surface of the device occurs, but after the power supply stops, the heated towel rail quickly cools down.
Devices with a cable last longer than liquid models. This is due to the fact that the heating element operates in a dry environment and the thermal cord can heat up to +90°C, and the heating temperature of the heated towel rail is limited to +60°C.
Such devices have a power ranging from 30-165 W. This ensures their higher efficiency, but their heat transfer will be lower. Devices with a heating cord are suitable for drying towels or underwear, but it is irrational to use them to heat a room.
What is the body made of?
An electric heated towel rail can be made from a square/rectangular, oval or round pipe. In order for the “towel” to serve for a long time, the thickness of the pipe wall must be at least 2 mm. Then the welds will be reliable.
If we talk about appearance, then products made from profiled pipes (rectangular or square cross-section) look more decorative and unusual. Models in a modern style are made from this material; they are also suitable for interiors in the style of minimalism and hi-tech. In such cases, the place for them is chosen “in plain sight”, and they serve more for decoration.
Various styles and options
You don’t always want to attract attention to a heated towel rail. In this case, round pipes are ideal, and even painted in a neutral color (white, gray) or the color of the walls. Most often, ordinary steel is painted, but many manufacturers can also paint stainless steel to order. There are practically no painted brass or copper models. They are a decoration in themselves. And they buy them precisely for their bright and memorable appearance.
An electric heated towel rail can be made from:
- black (structural) steel;
- of stainless steel;
- copper and its alloys - brass, bronze.
The most inexpensive option is structural steel. The inside is coated with an anti-corrosion compound, and paint or a layer of spraying (chrome plating, nickel plating) is applied on top. Such models are mainly made of the “dry” type - with a cable or a dry heating element. But there is also a liquid type.
More traditional forms - different types of “ladders”
Stainless steel products are more durable. They can last 10 years or more. But subject to mandatory grounding (to eliminate the possibility of electrocorrosion). Some manufacturers suggest covering the inside of the pipes with a layer of polymer (Sunerzha) to prevent corrosion. A good solution, but it raises the price significantly. But the service life is longer.
Some consider copper or brass electric heated towel rails to be the most decorative. One can argue here, but there really are interesting models. True, the price is completely immodest. If we talk about practical aspects - caring for a heated towel rail - then it is the copper and brass ones that require the greatest and most careful care. Their surface must be polished regularly using special products. Otherwise, in conditions of high humidity, it becomes very unsightly.
Official energy consumption ratio
Energy consumption coefficient is the ratio of the entire period of operation of the device to the time of its active heating, when maximum energy is consumed. This indicator is close to the concept of efficiency. The better the device retains and longer releases the heat obtained by heating with electricity, the less energy it consumes and the lower the coefficient.
For household heated towel rails, this figure ranges from 0.4 (24 minutes of energy consumption) to 0.16 (10 minutes). It is influenced by the design of the appliance, as well as how much laundry is dried and how wet it is.
If the device is also used to heat the room, then the value also depends on the proportion of the equipment’s power to the air exchange of the ventilation system.
Advantages of an electrical device
Here's what a person will benefit from after purchasing an electric heated towel rail for a room:
- eliminate leaks: if water models can leak, then the likelihood of such an outcome in an electric type is completely excluded;
- save: energy consumption is minimal and several times less if batteries or heaters were used;
- gain independence from utility systems: if you choose a water-based model, you can become dependent on utilities, which can change the water supply pressure.
However, you should not blindly follow all the advantages, because for some they actually are not such. First of all, you need to analyze the general position of the space and what is really needed for it. After all, if the bathroom already has a battery, then buying such a “dryer” is pointless.
How to calculate monthly consumption rate
To calculate the electricity consumption of a heated towel rail per month, the value of its power and the demand factor are taken from the device’s passport (for such devices it is taken equal to 0.4).
The calculation is performed using the following formula: EE = P * K * T, where:
- EE—electricity costs;
- P—device power;
- T is the time it works during the day.
If a heated towel rail with a power of 500 W is installed and it works for 4 hours per day, then 500x0.4x4 = 800 W, i.e. per month you get 24 kW.
In 2011, a study was conducted in which heated towel rails with a power of 300 and 600 W were tested. Both devices were set to maintain a surface temperature of +45°C for 3 days. The result was:
- A 300-watt device consumed 9.6 kW;
- 600-watt - 6.9 kW.
Such indicators are explained by the fact that less powerful equipment for heating the coolant to a given temperature worked at maximum load, and therefore spent more energy.
A more powerful heating element quickly heated the heated towel rail to the desired temperature, and then only turned on periodically to maintain it within the specified limits.

Margaroli Vento 500 530x630 box in the interior.
Parameters and connection. The device is designed for a hidden connection to a 220 volt AC network. A power consumption of 100 W is enough to heat the circulating coolant to a temperature of 70°C. There is an automatic shut-off to prevent overheating.
What power of heated towel rail should you choose for your needs?
If the device will only be used for drying towels and clothes, then its power of 35 W/m² is sufficient. If it is also used for heating a bathroom, you will need 140 W/m². This will be enough to maintain a room temperature of +25°C during the heating season.
If you install a heated towel rail with a lower power, it will not be able to heat the air to the required temperature and, at the same time, the electricity consumption will be greater. A device that is too powerful should not be installed. Due to the thermostat, electricity consumption will not increase, but turning it on/off frequently will lead to a reduction in service life.
Calculation example
In most multi-storey buildings, the bathroom area is from 3 to 5 m², although in private buildings it can be up to 10 m² or more. When choosing a heated towel rail, the best option is 140 W per m², i.e. for a bathroom with an area of 4 m² you will need a 560 W device.
You can always choose a model whose power corresponds to the area of the room. A deviation of the power indicator by 20-30 W is considered insignificant and does not affect the operation of the device.
When choosing a heated towel rail only for drying clothes, the given parameters are not followed. In this case, the main attention is paid to the dimensions of the device so that the towels of all family members fit on it.
Comparison with a water heated towel rail
Water models are connected to a heating or hot water system. Hot water circulates inside them, thereby heating the surface of the device. When choosing such models, pay attention to its dimensions, as well as the pressure for which it is designed, the optimal indicator is 7-10 atm.
The main disadvantage of a water appliance is that it only functions when hot water is supplied. If it is turned off in the summer, then the heated towel rail does not work either. If the temperature of the water model cannot be adjusted, then many electric options have the ability to set its value.

Tips for reducing energy costs
To reduce energy costs as much as possible, you need to purchase equipment that has energy-saving components.
Installing a thermostat
Many models have a temperature sensor and regulator installed at once. They are installed only on liquid models with heating elements. Cable heated towel rails do not have a thermostat, because... their maximum heating temperature is +60°C.
Using models with a timer
It is convenient when such a device is additionally equipped with a timer. With its help, you set the time to turn on the device, and it will automatically turn on and off. This allows additional energy savings.
External signs of normal quality
Something else worth paying attention to is the quality of the seams. The first sign of a high-quality seam is that it is smooth and uniform. Without cavities, strong protrusions and depressions. If you pre-select a manufacturer, find information about exactly how, on what equipment, and in what environment welding takes place. This is especially critical for stainless steel. It must be cooked in a protective (usually argon) environment so that the alloying metals do not burn out. If you weld stainless steel using the usual method, in an atmosphere with oxygen, the “stainless” properties in the weld area are not preserved. Then it is the seam that begins to rust and leak. Therefore, manufacturers usually indicate exactly how stainless steel is welded.
There are models with folding parts
It is also worth paying attention to the quality of painting, chrome plating, and nickel plating. There should be no defects, unpainted areas, or foreign inclusions. Only if all these conditions are met can you think about buying.
Should you use a heated towel rail to heat your bathroom?
A heated towel rail can be the main source of heat in the bathroom of a multi-storey building. Here this room is surrounded on all sides by other warm rooms, so the power of such a device is sufficient for heating. In private homes, the bathroom walls are often external, so heat loss is greater. In such cases, only a heated towel rail for heating may not be enough, then it is used as an additional source of heat.
If this device will be the main source of heat in the bathroom, then its thermal power should be in the range of 100-140 W/m², then it will cope with the task.
