The maximum power consumed when operating an electric towel rail (or combined model when operating from an electrical grid; see «Type»). As a rule, this value corresponds to the operating thermal capacity of the electric heater, so that it is possible to estimate the overall efficiency of such devices from the power consumption. In addition, energy consumption and network load depend on this indicator.
As a rule, manufacturers select the power consumption depending on the size of the towel bar - to ensure it is sufficient for heating and effective drying. This requires relatively little energy. But in the role of a heater for the bathroom is more convenient to use water heaters - they are easier to achieve high power (and such heating is cheaper). Therefore, electric heaters in modern models have low power - the devices
more than 150 W are rare, and the most low-power devices do not reach
and 50 W.
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.
The location of the cable on the towel rail housing allows you to choose the right model, so as not to invent with the connection of the device to the socket.
— Left. The electrical wire is placed on
left side of the body, which allows a neat and concise installation of the towel rail on the wall, on the right side of the plug.
— Right. The power cable is removed via
right side of the housing. This wiring arrangement is advisable to choose when the towel rail will be mounted to the left of the outlet.
— Hidden.
Hidden cable liner involves connecting to the power grid behind the false wall or by means of electrical communications hidden in the wall. In this case, the heater terminal box itself is most often placed closer to the center of the housing. As a rule, the towel rail with the option of a hidden connection has a short wire without a plug at the end. But there are models that are not normally equipped with a connecting wiring - in this case, it is necessary to connect the end of the cable hidden in the wall to the terminal box heater. Also on the market there are models that support both connection options: both hidden and classic (using a conventional power plug), which allows the user to determine which option will be the best for him.
Certification of the towel rail for dust and water protection according to IP (Ingress Protection) standards. The specific degree of such protection may vary: for example, some models remain fully operational under the influence of water spray from any directions, others allow only the entry of individual drops of water in the vertical plane. These points are usually indicated in the instructions, they must be taken into account before installing the towel rail.
