Design
The design of the towel rail determines primarily its appearance, but can affect more practical aspects - for example, the installation features. The most popular modern designs include
serpents (incl.
M-shaped and
P-shaped a/href and" (including volumetric), protrusions in the direction of, and angular constructions. In addition, there are original designer solutions. They are all described below.
— P-shaped coil. Type of coils described above, in which the main (leading) pipes are bent in the form of the letter «P». Most often, between the «legs» of this letter there is an additional coil from pipes of a smaller diameter - thus, with small dimensions the towel rail provides many «seats». However, there are also maximally simple models, without additional coil.
— M-shaped coil. Coils (see above), in shape resembling the letter M, laid to the side. In essence, it is a version of the classical S-shaped coils, having three bends: two to one side and one, between them, to the other.
— Ladder. The design of such towel rail is based on two vertical elements (tubes or bars), between which are located horizontal jumpers-crossbars, on the manner of steps of the usual stairs (hence the name). Modern models - «ladders» are very diverse, ca...n have different width and height, differ in the number of crossbars, equipped with additional shelves for drying (more about all this see below), etc. At the same time, the price of such devices is quite low. Of the drawbacks of the ladder it is worth noting that the towel hung on this design is likely to close several bars under itself - this makes it difficult to simultaneously dry several towels (although it increases the speed of the process by contacting the tissue at once with several heated bars).
— Volumetric ladder. Type of ladder (cf. above), in which the jumpers are not located directly between the vertical tubes, but are displaced relative to them forward and/or backward. The simplest variant of the three-dimensional ladder is one row of crossbars moved forward; this slightly increases their useful length at the same width of the entire structure, but on this the key differences with the normal ladder end. There are more complicated variants, with the arrangement of the jumpers in two vertical rows - for example, one row is directly between the tubes, and the other is forward or one is offset forward and the other is backward. These towel warmers are very useful if you need to dry several towels at the same time, but they are usually quite expensive.
— Side protrusions. This design can be called «one-way ladder»: it also combines vertical elements and horizontal jumpers, but the jumpers are fastened only on one side - the second is located «on weight». This gives the towel warmer an original look. However, in water models of this design is quite difficult to ensure efficient water circulation, so the «protruding» design did not get widespread.
— Corner. As the name suggests, models of this type were originally designed to be installed in the corner of the bathroom. This requires appropriate design features; they can be different in different models. Note that there are options for both «normal», internal angle, and external, protruding.
— Designer. This category includes all towel warmers with original appearance and not belonging to any of the above categories. An indispensable element of their design is only the presence of horizontal jumpers (so that, actually, there was where to hang towels), but the options for their mutual arrangement, connecting each other and with a support, etc. are limited only by the imagination of designers.
Thermal power
The working capacity of the towel warmer - simply put, the amount of heat it receives when working normally. This parameter is only relevant for water models (and for water-based combination devices). For electric heaters, the power consumption is given (see below) with a similar value.
The thermal power is important in light of the fact that the towel rail often plays the role not only of the dryer, but also of the heater for the bathroom. If the ceiling height in such a room is standard 2.5 - 3 m, you can use such a formula to evaluate the effectiveness: on 1 m2 of area at least 100 watts of thermal power is needed. For example, the smallest modern models give out
less than 300 W, this is enough only for the smallest bathrooms (or for use as an auxiliary heating source). The indicator in
300 - 600 W is considered relatively low,
600 - 900 W - average,
- 1200 Wat can exceed the largest thermal power models, greater than larger ones"/list/88/pr-11658/">1200 W.
When choosing on this indicator should take into account two points. Firstly, the thermal power is specified for a certain water temperature (usually of the order of 60 °C or 75 °C); if the temperature is different, the actual capacity of the towel heater will differ from the declared. Therefore, it is worth choosing a device with a certain reserve in power. Secondly,
...in combined models (cf. «Type») the power of the electric heater is added to the thermal power of the water heater, and the overall efficiency of the device will be determined by the sum of these capacities.Max. operating t
The highest operating temperature of the towel bar. The features of this parameter depend on the type of device (see above). For water models, the maximum water temperature (or other coolant) is specified here, at which the device can be guaranteed to operate indefinitely for a long time without risk of damage. Usually this value is not less than 95 °C, and in some models may exceed the boiling point of the water and reach 105...110 C. This is usually more than enough for rooms with central heating and hot water supply, but if the heating is provided autonomously, It is necessary to specify separately the range of operating temperatures in the contours and make sure that the selected towel rail will fit them.
In the case of an electrical model, maximum operating temperature means the highest temperature to which the device can heat up. Usually, when it is achieved, the heating is automatically switched off and turned on only when the temperature is significantly lower. In this case, the usual values are 60...70°C, which is comparable to the standard water temperature in the district hot water supply systems - this temperature ensures efficient drying and at the same time does not create a risk of being burned by accidental touch.
Centre distance
The distance between the axes of the main pipes connecting the towel rail. This parameter is critical in the selection of water towel rail and its frames into existing pipes. To ensure a neat design after installation, the spacing between the towel rail and the pipe in the wall must be the same. If the figures match, you will not need to use accessories in the manner of plumbing knees, adapters, adapters, etc. The classical dimensions for the interaxial distance are
400 mm,
500 mm and
600 mm.
Operating pressure
This term usually means the highest heat carrier pressure that the towel rail is able to bear without consequences for an unlimited time. Higher values are allowed for a short time, but the regular working pressure in the system should not exceed the characteristics of the device - otherwise there is a high probability of damage to the product, with a «flood» and other related troubles. In general, it is believed that this indicator should be at least 2 bar higher than the actual working pressure in the system - this will give an additional safety margin in case of emergencies.
Number of jumpers
Number of jumpers - horizontal elements - provided in the design of the towel rail. It is on them are placed towels and other things designed to dry; however, there are models in which not every jumper is suitable for this. The fact is that horizontal elements can be placed in groups, inside which the distance between them is so small that it is very difficult, if not impossible, to place a towel there. In such groups, only the upper bridge supports, and the rest play the role of additional heating elements, increasing the heating area and, accordingly, the efficiency of drying the fabric. This feature is quite common in models with more than 10 jumpers.
It can be said that, in theory, the more jumpers - the more things can be hung on the towel rail; however, in practice, this moment largely depends on the design of a particular model, And the more horizontal elements there are, the more likely they are to be grouped. Also, it is worth paying attention to the width of the towel rail, according to this criterion you can conventionally divide them into
broad and
narrow.
Manufacturer's warranty
The warranty period declared by the manufacturer for this model - that is, the period during which the manufacturer guarantees normal operation. It can be
5 years,
10 years and even more. The specific terms of the warranty may vary, but as a rule it applies to factory defects and faults caused by the manufacturer/seller and detected in normal use, without violating the rules.
The longer the warranty period - the more reliable is the towel rail, the higher its overall quality, other things being equal, but the more expensive it will be in comparison with analogues.
