Towel dryer - a device that not only provides comfort, allowing you to conveniently place and quickly dry towels and underwear. It is also an important sanitary device: it prevents the development of fungus on the tissue. Therefore, the value of a heated design is difficult to overestimate. It remains to find out its power consumption.
How much electricity does an electric heated towel rail consume
The range of electricity consumption is quite extensive. This is due to both the variety of bathrooms and the expected number of visitors, as well as the size of the devices themselves.
What affects energy consumption
- The main factor, first of all, is the engineering and technical layout, what type of electric dryers are:
- Liquid. All models are quite powerful: from 1000 to 300 watts. The main component providing transportation and storage of heat is oil or water. And it consumes electricity and produces heating - TEN. Its inclusion and shutdown occurs with the help of sensors. In the simplest case, when reaching the maximum and minimum temperature limits. The main current consumption falls on the initial heating period, and then the heater only supports the specified mode.
- Cable. Relate to medium and small devices: from 30 to 165 watts. Heating is carried out using a special cable. These devices are less voracious, but their heat transfer is much less. If the task is to only dry, but not heat the room - these models can be a very reasonable and balanced solution.
- Combined. Combine the advantages of the two previous types. They have a significant drawback - they are significantly more expensive.
- Additionally, within the model range, the characteristics of heat transfer come to the fore (the higher it is, the more usually the device is more voracious). Moreover, the presence of a thermostat and / or timer provides tangible savings. A heated towel rail, the heating element of which works all the time, will consume electricity much more intensively than the one that is turned on by the timer from time to time. A device capable of working only at any one temperature will yield in energy efficiency to a flexibly adjustable one that has a thermostat.
- Cable heated towel rails should not be used for heating, as they have insignificant power characteristics, a high coefficient of energy consumption and are intended only for drying.
Power factor
This parameter is not indicated in the passport of the heated towel rail, mainly because it depends on many nuances. And he expresses the ratio of the total time of heating and drying to the time of active heating with current consumption and is close to the concept of efficiency. The better the design retains heat, and the longer it gives off to the surrounding space, and the less it consumes electricity, the lower the coefficient.
For electric heated towel rails, this indicator ranges from 0.4 (the most common option and corresponds to 24 minutes of consumption) to 0.16 (the most energy-efficient - only 10 minutes). Moreover, it depends not only on the design features of the device, but also on how wet and linen and how much is dried. And taking into account the related task of heating - how much its power is proportional to the air exchange of the room ventilation system (for the bathroom - 25 m³, for the combined bathroom - 50 m³), as well as humidity and the amount of drying clothes.
Calculation of electricity consumption
It is not difficult to calculate the monthly power consumption of a heated towel rail if its power is known. In extreme cases, you can look into his passport, which will necessarily indicate the desired number.
Important! The formula for the calculations is simple: the power of the device must be multiplied by the number of hours of its operation in one day and by 30 - the average number of days in a month.
For example, a household appliance with a power of 100 W, working 5 hours a day, is calculated as follows:
50 W x 5 hours x 30 = 7500 W / h
These are approximate calculations. They are based on the assumption that the temperature in the room of the apartment is not lower than 20 ° C, and a certain average volume is chosen.
There is a more rigorous technical formula that takes into account almost all factors by including an additional factor - the energy consumption coefficient. The easiest way is to find out this parameter empirically (experimenting with an existing device): from the difference in the energy consumption of the apartment for the same period of time, with a working and non-working heated towel rail. The result will be energy consumption for a test number of hours.
In conclusion, I would like to note some nuances that may be useful when choosing a suitable model.
For the usual and most common bathroom with an area of 3 m³ - 5 m³, a dryer of 30-40 watts is absolutely enough.
Cable towel rails rarely have a temperature controller in their device, this is the prerogative of liquid devices.
For a small family, rotary devices are ideal. Their shelves are small and rotate 180 degrees in the horizontal plane.
Electric heated towel rail is a profitable and useful purchase. It is durable (average service life of about 30 years), helps to reduce dampness in the room, makes hygienic procedures not only pleasant, but also protects the tissue from mold and fungus. Hopefully the article was helpful. Especially for those who are going to purchase this installation in the near future.
