Good day! What is so necessary in the winter when the batteries are off, or when they do not heat well - right, heaters. It is the heaters that help us maintain a comfortable room temperature in winter.
Sometimes the heating of batteries is simply not enough, or heaters are used where there is no heating system, these are garages, summer cottages, pavilions, kiosks, etc. Before using the heater, you should first calculate how much electricity the heating devices consume, and how much you will have to pay for electricity. Let's try to figure it out today.
So, the most popular heaters are of the following types:
Fan heater
Fan heater - is a small gun, inside there is a spiral that heats up and a fan that quickly accelerates heat, this is the cheapest and most affordable option for heating the room for everyone. The combustion of air by this device is the strongest, unlike others, therefore its use assumes periodicity, i.e. switching on with short interruptions. Another disadvantage of this type is the noise of the fan, there is no noise in other heaters.
Long-wave infrared heaters: how the device works
Reviews of these devices are good, especially among those who use this equipment in industry. A distinctive feature of these models is their high power. Accordingly, the area of the heated room can be quite large.
There are many models on the market with different mounts. They are ceiling and wall mounted. They have an anodized panel as a heating element.
Before using an infrared heater, you must familiarize yourself with the principle of operation of the device.
The power supply in these heaters is a network with a voltage of 220 V. The limiting oscillation frequency must be maintained within 45 Hz. Of the advantages, many note the rather rapid heating of objects and air in the room. However, it is not recommended for a person to be under such a device for a long time. The dimensions of these types of heaters are large, so many face difficulties when installing them. For the price, they are also not quite affordable for ordinary people.
Convection heater
Convection heater - is considered one of the safest heaters, the principle of operation of a convection heater is mixing and circulation of air layers, at the bottom of the convector there is a grate through which air enters, from above, already heated air comes out through the holes. The convector provides protection against overturning, against overheating, this type of heater can be hung on the wall for convenience, it has a flat shape and small size.
What affects the electricity consumption of the heater?
The main characteristic by which you can determine how much the heater will wind is the power consumption of the device. The higher it is, the correspondingly greater will be the consumption of electricity. It should also be noted that consumption depends on the mode in which it operates.
Convection heaters generally have an energy consumption of 750 W, 1 kilowatt, 1500 W, 2 kW, maybe more. For fan heaters, consumption is 1500-2000 W per hour. For oil also the limits are from 1000 to 2000 W / h.
Let's calculate how much electricity the heater will spend if it operates at full power of 2000 watts. In total, we get 2 kW per hour.If we take that in winter the heater heats up 2 hours rests, we get 8 hours of work.
2 * 8 = 16 kW per day, and if we take the average price for 1 kW of electricity 4 rubles, then we get 16 * 4 = 64 rubles. in a day. The numbers may be less if you initially use a couple of hours to the full and then use a less consumption mode to maintain the temperature.
Based on the data obtained in the calculations, it is possible to calculate how much electricity the heater will consume in 1 month and for the entire cold period.
Thus, in order to determine how much electricity a heater consumes, it is enough to know its power consumption in the absence of operating modes, and if there are heating modes, know how much electricity each consumes.
There are 4 types of heaters:
- Convection,
- Fan heaters,
- Oil radiators,
- Infrared heaters.
Shortwave and longwave infrared heaters: types of devices
The main thing that distinguishes infrared devices is the heating temperature of the tungsten coil and the material around it. The second criterion is the level of power consumed by the device and electricity consumption.
In properly working heaters, the spiral heats up to a temperature of over 700 ° C.
Infrared heaters are usually divided into the following categories:
- Longwave;
- Shortwave.
There are a huge number of infrared heaters, the types of which can be found on the Internet or in specialized stores.
In order to determine whether a device belongs to one of the groups, it is necessary to carefully look at it, even with the naked eye. Shortwave new infrared heaters in the dark release waves that can be seen by the human eye. But we cannot see long-wave streams.
Typical representatives of this group are incandescent lamps or conventional gas emitters. During their operation, objects located close are heated. It is due to the absorption of a large part of the emitted waves by the internal environment that a person has the opportunity to see something.

Electricity consumption calculations for household appliances
Before figuring out how much the heater consumes electricity, consider the consumption of other household appliances. All appliances that require electrical energy to operate consume this energy in accordance with their capacity. However, not all such devices work in the same way and, accordingly, electricity consumption is not the same. Appliances such as an electric kettle, TV, various types of lighting devices, when turned on, begin to consume the maximum amount of energy. This amount of energy is indicated in the technical characteristics of each device and is called power.
Let's say a kettle with a power of 2000 W was turned on to heat the water and worked for 10 minutes. Then we divide 2000 W by 60 minutes (1 hour) and it turns out 33.33 W - this is how much the kettle consumes in one minute of operation. In our case, the kettle worked for 10 minutes. Then we multiply 33.33 W by 10 minutes and we get the power that the kettle has consumed during its operation, i.e. 333.3 W and it is for this consumed power that you have to pay.
The work of a refrigerator, an electric stove and an electric convector takes place in a slightly different way.
How can you save money?
It is, of course, unreasonable to completely abandon the benefits of modern life, but in order to save money, you can pay attention to energy-saving refrigerators, because this device will work all year round, regardless of weather conditions. If you calculate how much energy a TV and a computer consume per month, you can completely influence this amount by choosing one working device.A monitor that is often turned on works all day without benefit, and a working TV becomes the background under which we carry out our daily activities. Getting rid of these habits is not easy, but after a month it will result in a reduced electricity bill.
Other methods of saving electricity:
- Replace all lighting fixtures with new energy saving or LED bulbs. The initial investment will pay off a hundredfold with serious savings and a long service life.
- If you use an electric kettle often, always pour just as much water as needed, not in reserve. Unfortunately, no energy-saving kettles have been invented yet, but it is entirely within your power to adjust the mode of use.
- Place your computer in Comfort Sleep mode. In this case, it turns off automatically if a certain time passes in inactivity. When turned on, it will accordingly consume less energy, which is also important.
- Defrosting the refrigerator and freezer on time is also part of the family's savings. When a significant amount of ice forms on the walls, energy consumption increases, so be sure to eliminate this factor.
- The use of heat-reflecting screens will help make heaters and convectors work more efficiently.
- Replacing the wiring and organizing local lighting in the kitchen or recreation area will also significantly reduce costs.
- The use of adapters and extension cords increases power consumption.
- When purchasing new electrical appliances, it is better to give preference to the economy class of consumption. The main positions are shown in the table.
One of the uncommon ways to save electricity is the installation of multi-tariff meters. This will allow some appliances to be turned on at night when electricity is cheaper. This practice has shown itself well in foreign countries, but unfortunately, has not yet taken root in our country.
It is probably impossible to completely abandon the use of electrical devices in the modern world. Even a gas boiler and a heating convector must consume a certain amount of energy for their functioning. If we are talking about a welding machine, boiler or air conditioner, the consumption is significant even with short use. Despite this, the consumer is buying more and more various electrical appliances, so it is useful to find out the main culprit of electricity bills, as well as proven methods of reasonable savings that will help to reduce costs.
Heater Electricity Consumption Calculations
Let's consider a case with a 2000 W convector. To begin with, on such a heater, it is necessary to set the air temperature that the convector must maintain, for example, 25 C. After supplying electricity to the heater, it will work for heating in full power mode, i.e. 2000 W., and in this mode the convector will work up to then (let's say 20 minutes), until the air temperature, which was initially set, is reached, in our case it is 25C. After that, the temperature control system will work and the supply of electricity to the heating element will stop, which means that the consumption of electricity will stop.
Unaccounted electricity costs
air conditioner - consumption in summer 100-150 kWh per month
Of course, in the previous calculation it is necessary to add one more item characterizing unforeseen costs. This is not only about using a coffee machine and other small household appliances, without which we can no longer imagine a comfortable life. Depending on the living conditions, a water supply station, a circulation pump in the heating system, electrical equipment of a gas boiler and a convector, as well as a water heater, heating boiler, electric stove or oven, welding can be used.The list can be enumerated for a long time, because in modern life, many household appliances are powered through the mains.
Electricity consumption in this case "pulls" and the electrical appliance is in "standby" mode when the wire is connected to the network. In fact, this is a trifle, but if you calculate the costs per month, year ...
oil heater - 150-300 kW / h in winter
Owners of air conditioners also have to pay extra for the possibility of a comfortable rest from the hot temperatures. In winter, consumption increases due to the use of a gas boiler, convectors and heaters. The consumption of electricity by an air conditioner, even with the smallest use, will cost about 100 - 120 kW per month, which can significantly increase your costs. The power of household heating appliances is also enough to "wind up" the same amount in cold weather, so before buying such equipment, it is necessary to calculate the appropriateness of its use.
Advantages of the Nobo heater when calculating electricity consumption
Heaters of the Nobo brand are considered to be the highest quality and most economical heaters today. Tests carried out at a manufacturing plant in Norway have shown that Nobo convectors heat up a room as quickly as a fan heater.
Indoor temperature 9.5 sq. meters rises by 10 degrees Celsius in 2 hours and 42 minutes - it takes 2290 W, and the convector goes into operating mode a little more than in 7 minutes. If the temperature is maintained further for 3 hours, the convector consumes 680 W / h.
Comparison with other heating appliances
The heating cable consumes approximately 2.1 kW of power per hour. A convector of electricity consumes an average of 1 kW over the same period of time, an electric boiler - 3 kW. The oil radiator heats up the room slowly, using 1-2 kW.
Among many heaters, an infrared heat source has the highest efficiency (approximately 90%). Therefore, at a power consumption of 1-1.5 kW, it quickly creates comfortable air in the room and then automatically turns off using a thermostat.
