How much electricity does a fan heater consume?
The fan heater consists of a small housing in which a fan and an electric coil are built-in. The operating process is very simple: the coil heats up and the fan distributes the heat. Quite easy to use and very quickly heats the room due to heat atomization. But it has several disadvantages: a lot of oxygen is required, since an open heating coil burns oxygen; When operating, the fan creates a lot of noise.
How much electricity does a 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 coil, since it is not cooled, which is dangerous due to 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 there will be a corresponding electricity consumption. Also, everything will depend on the operating mode of the device; if it operates in maximum mode, then the consumption is greater, if in minimum mode, then less.
What affects the electricity consumption of a fan heater?
Fan heaters are one of the most popular types of heaters. This is influenced by its compactness and the fact that it quickly heats the room. They are easy to carry, easy to use and transport. No special tools are required for their installation.
There are several types of fan heaters, which we will consider. Their electricity consumption depends on the model, manufacturer’s power, and purpose.
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 quickly heating large rooms.
Fan heaters with a regulator have several powers and operate depending on the one set. For example, in position 1 it works with a power consumption of 500 W, in position 2–1000 W, and in position 3–1500 W. Modern models may have more power control positions. The main disadvantage is that constant supervision is required both over the time it takes to switch power, and so that it does not overheat. Nevertheless, it makes it possible to accurately calculate energy consumption.
Fan heaters with a regulator and thermostat are 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 record it on the thermostat. Its energy consumption depends on various factors, primarily on the temperature to which the room must be heated and then maintained at this temperature. It is clear that the greater the difference between the initial temperature and the required one, the more electricity will be needed. Allows you to select several powers, as well as several fan operating modes.
Important! Fan heaters require normal air circulation to operate! Therefore, you should try to install the device in places where this can be done. Do not place close to walls, furniture, or work tables. In addition to the fact that if there is insufficient air circulation, the heating of the room will be less, and therefore the electricity consumption will be greater, this can lead to overheating of the coil and its fire.
The heat gun fan heater 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.
If compared with a convector of the same power, the convector will heat 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 cost too much.
Example of calculating electricity consumption
Let's try to calculate the maximum electricity consumption of the device. If the factory specifications indicate that its power is 2000 W, this means that it will consume 2 kW per hour of operation in maximum mode. In winter, the approximate operating mode is as follows: an hour is on, and 2 is off. Therefore, there will be 8 hours of work per day.
2*8 and we get 16 kW of energy per day. If the average price for electricity is 4 rubles, then it turns out that heating the room for a day will cost you 64 rubles. These are the numbers for the 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.
