The fan heater consists of a small housing in which a fan and an electric spiral are integrated. The process is very simple: the spiral heats up, and the fan distributes heat. It is quite easy to use and very quickly heats the room, due to the dispersion of heat. But it has several drawbacks: a lot of oxygen is needed, since an open coil for heating burns oxygen; during operation, the fan creates a lot of noise.
How much electricity does the fan heater consume?
The fan can be turned off, but then the heating effect of the device is small. In addition, this will lead to rapid burnout of the spiral, since it does not cool, which is dangerous by fire.
In order to understand how much electricity your heater will consume, first of all, you need to pay attention to the factory characteristics, depending on the power consumption and there will be an appropriate electricity consumption. Also, everything will depend on the mode of operation of the device, if it works in maximum mode, then the flow is greater, if in the minimum - then less.
What affects the consumption of electricity by a fan heater
Fan heaters are one of the most popular types of heaters. This is affected by its compactness and the fact that it quickly heats the room. They are easy to carry, easy to use and transport. For their installation does not need special devices.
There are several types of fan heaters, which we will consider. Their electricity consumption depends on both the model, the capacity of the manufacturer, and the destination.
Based on the types and design, they can be divided into types:
- fan heaters with regulator;
- fan heaters with regulator and thermostat;
- fan heaters for fast heating of large rooms.
Fan heaters with a regulator have several capacities and work depending on which one is set. For example, in position 1 it works with a power consumption of 500 watts, in position 2-1000 watts, and in position 3-1500 watts. In modern models, there may be more power control provisions. The main disadvantage is that you need constant supervision over the time for switching power, and then, so as not to overheat. Nevertheless, it makes it possible to accurately calculate the energy consumption.
Fan heaters with a regulator and thermostat represent a more complex design. It provides for disconnecting the device from the network in case of overheating. Therefore, there is no need to constantly monitor him. You can turn it on and go about your business. The built-in thermostat allows you to turn off the heater when the desired temperature is reached in the room. To do this, it is enough to catch the moment of the temperature that we need and fix it on the thermostat. Its energy consumption depends on various factors, primarily on the temperature to which the room should heat and then maintain this temperature. It is clear that the greater the difference between the initial temperature and the required, the more electricity will be needed. Allows you to select several capacities, as well as several modes of operation of fans.
Important! For operation, fan heaters require normal air circulation! Therefore, you should try to install the device in places where it is possible to do. Do not put close to walls, furniture, work desks. In addition, with insufficient air circulation, the heating of the room will be less, and consequently, the electricity consumption will be more, this can lead to overheating of the spiral and its ignition.
Fan heater "heat gun" is used to quickly heat large rooms. For example, clubs, discos, conference rooms, such rooms where people do not always gather, and there is no need for constant heating.
When compared with a convector of the same power, the convector heats the room in 30 minutes, and such a fan in 10. The difference is three times. But it consumes a significant amount of electricity and is completely unsuitable for domestic needs. Heating will be too expensive.
Example of calculating electricity consumption
Let's try to calculate the maximum electricity consumption by the device. If the factory specifications indicate that its power is 2000 watts, it means that in an hour of operation in maximum mode it will consume 2 kW. In winter, the approximate mode of operation is as follows: the hour works, and 2 is turned off. Therefore, 8 hours will work per day.
2 * 8 and get 16 kW of energy per day. If the average price for electricity is 4 rubles, then it turns out that heating the room during the day will cost you 64 rubles. These are the numbers for maximum mode. In economic regimes, of course, the cost will be lower.
Thus, knowing the power of the fan heater and the approximate operating time, we calculate the cost of heating.
