Fan power consumption
On a PC or laptop, the dimensions and the design of the coolers are approximately the same, the difference is only in small details. There is no difference in the type of power, and when connected through the molecu, and directly to the motherboard using 3 PIN and 4 PIN, the electricity consumption will be almost the same.
The difference depends on the size of the impeller. if it is larger, then to promote it, you need a higher power electric motor. However, the difference is in this case meager. So, small fans with a diameter of 40, 80 or 92 mm on average consume about 3 watts. If a cooler is 120 or 140 mm in size, it consumes 4 watts.
Large.diameter fans are usually not used for cooling the housing, since there is no suitable seat. As much as indicated above, consumes the impeller that cools the central and graphic processor. Notice each. If there are 3 powerful fans on the video card, everyone will consume 3-4 watts.
How to calculate energy consumption
Knowing the current force that consumes the impeller, it is easy to calculate the final value in the watts by the method of multiplication by 12. Why 12? This is a current voltage that is used to power cooler. Who has not remembered yet, then I bring a formula from the school course of physics, p = IU.
For example, the cooler is designed for the current strength of 0.3 amperes. Multiplying, we get 3.6 watts. As a rule, the current force on which the impeller is designed is indicated on the nameplate glued on it.
Which affects the consumption of electricity by thermal talent?
How much electricity is consumed by the heat.cognrator, it is determined by several parameters:
How the energy area of the room affects the energy consumption?
Each model of the heat.rector is designed for heating the premises of a certain area. Not only the size of the heating element and its ability to heat transfer, but also the fan power, the structure of the case, the structure of the case, as well as other parameters depends on this. For Polaris models, the recommended heating area is 20 m2. They can be used in rooms of larger area, but then the device will work longer, with a large energy consumption. On the contrary, if you install it in a room of smaller area, you will need to turn on the device less often, and it will consume less electricity.
When calculating how much electricity the heat.cognrator consumes, it is more correct to take into account the area of the room, but its volume. To do this, take into account the height of the ceilings in the room. If it is average (2.5-2.7 m), the volume of the room is 50-55 m3, the area recommended for the Polaris devices (20 m2) is preserved. If the height of the ceilings is greater, the area is proportionally reduced so that the volume is the same 50-55 m3. With low ceilings, the area of the heated room can be slightly larger.
The value of heat loss is the main indicator
The more heat losses, the faster the room cools, and the more electricity it spends the heat cautifier to maintain a comfortable temperature. Heat loss depends on many parameters:
- the difference in air temperatures on the street and indoors;
- the effectiveness of insulation of external walls, ceilings, window openings;
- quantity, window area;
- the presence of drafts, direct ventilation exits to the street.
Heat loss can depend on the weather: in frost or with a strong wind, “blowing” heat, they will always be higher. In well.insulated houses, they contract. They will also be less if the window is insulated in the room, tightly closed.
As the characteristics of the thermal fanbox affect how much kW it consumes?
There are several ways to make the heat cautifier more economical:
The correct selection of the operating mode affects how much electricity the heating venture spends:
- If you need to quickly warm up the cold room, the device is turned on for a short time, but for maximum power;
- If warming up the air can be slow, or you need to maintain a certain temperature, the minimum or average power is set.
Thermostat allows you to automatically control the operation of the device. It works when the air temperature in the room drops below the given value, then the heating is turned on. When the air warms up enough, the thermostat turns off the device. With automatic control, even a 2000 watts heat.core consumes a little energy. The device works only when it is necessary, which provides greater savings.
If the heated air is distributed evenly, the room will warm up faster, and electricity consumption will decrease. Polaris’s home heating tanks have powerful fans and wide air supply holes. This helps distribute heat quickly and evenly.
How can you reduce electricity consumption?
So that any thermal core or heater (including ceramic or infrared), consumes less energy, you need:
- put the device as low as possible (preferably on the floor), since warm air rises from floor to ceiling;
- ensure uniform heat distribution: it is better to direct the device so that the flow of heated air passes through the entire room;
- Close the windows and doors tightly to reduce heat loss (but periodically ventilate to access fresh air);
- warm the cold room in maximum mode, and then reduce power.
These measures will help reduce electricity consumption during the operation of the thermal talent even in the coldest months.
The most energy.consuming household appliances
The life of a modern person is inconceivable without electrical appliances. We cook and warm up food, store foods, do cleaning, wash, iron, work at the computer, conduct leisure time, etc.D. All their lives, people interact with electrical appliances, using them to ensure a more comfortable and more effective life to themselves and their loved ones.
But did you think how much electricity consumes all these household appliances together and separately? After all, many of us often think about saving electricity. But how to achieve this if you do not calculate consumption? Let’s calculate how our comfortable, so.called civilized everyday life turns.
First of all, in order to calculate consumption, you need to know the power of each household appliance, that is, the number of watts consumed in the usual everyday mode of operation.
On any device, as a rule, there is a sign with its electrical characteristics. In extreme cases, they can be seen in the instructions. We are interested in the power designated VT or W, for example, the device can be clearly indicated. 40 W, or ampers “A” need to be multiplied by 230 in. Suppose that 230 in 0.17 A can be indicated on the fan. this is approximately 40 watts and t. D.
Of the most common and regularly used household electrical appliances, they consume the most: electric kettle. about 2 kW, air conditioning (or electric heater). 2 kW and microwave oven. 1 kW. We often use them every day, although the air conditioner and heater are more seasonal devices, but we will not ignore the attention and their. In order to determine the amount of kilowatt hours per month, it is enough to change the power and number of hours of operation of these devices per month. So, let’s get down.
If we assume that an electric kettle works for 20 minutes every day (4 times for 5 minutes), then it is 0.66 kWh per day and, respectively, 19.8 kWh per month.
Using the microwave 5 times a day for 3 minutes at full power, we get 0.25 kWh per day or 7.5 kWh per month.
The air conditioning (or heater) working 8 hours will wind us 16 kWh per day, and 480 kWh will be released in a month. Agree, this is quite a lot.
Now let’s pay attention to the refrigerator. It works around the clock. Typically, the refrigerator documentation indicates consumption for a whole year. These figures range from 150 to 460 kWh (per year!), which gives from 19 to 38 kWh per month. As a result, it turns out that the refrigerator wraps a minimum of the same amount as the kettle, and maybe twice as much.
And what about washing? Much depends on the washing mode, the loading volume and temperature to which the machine warms up the water. In general, during washing inside the washing machine, a engine, pump and heating. Approximately you can take average power during washing for 1.5 kW. If we assume that washing is steamed for 1.5 hours 3 times a week, then 27 kWh comes out in a month. This is the first place.
As a result: in the first place. Washing machine, on the second. a refrigerator, on the third. an electric kettle. We consider the air conditioning and the heater exceptions, since we will understand justice that they are used not always and not everywhere.
By the way, we forgot about the iron. Meanwhile, if the housewife strokes 3 times a week for 1 hour, then the consumption goes approximately the same as the electric kettle.
It is especially worth noting an electric warm floor. If you have it, then approximately 0.10 kW per 1 square meter of floor area is for sure. For example, take a bedroom area of 12.5 square meters.m. This is 1.25 kW. If the system works 16 hours per day, it turns out 600 kWh per month. The number of numbers is close to air conditioning or heater.
By the way, for a more accurate determination of the power of a particular consumer, you can use the household vattmeter or counter, about how to do this a separate article. How to measure the power consumed by home electrical appliances
With the help of a wattmeter, you can do without averaging and get maximum accuracy. Thus, you can take turns measuring the consumption of a computer, a TV, a fan, a table lamp, and even a charger. To obtain a result in money, it remains to change the resulting value in KWh to your electricity tariff.
Know Your Electricity Consumption of Pedestal Fan
How to calculate energy consumption
So, you looked into the instructions and found out the power of the multicooker. But how to calculate how much light it will be pulled? If you have an unit with a capacity of 1000 watts, then, in theory, in an hour of work, the slow cooker should spend 1 kW of electricity. If you use it twice a day for an hour, then 2 kW will burn in a day. Multiply this indicator by the tariff of your region and find out how much money you have to pay for the use of a kitchen assistant. This is theoretically, but in practice there will be completely different numbers, because the multicooker uses such an amount of electricity only in heating mode, and then simply maintains the desired temperature. Electricity consumption in this mode is 15–25% of the maximum power. So the real power consumption will be 250 watts per hour for a multicooker with a capacity of 1 kW or, for example, 200 W for a power of 800 W.
Having estimated how many times a day or a week you will use a slow cooker, you can calculate how many kW on the counter will be added in a month. If you turn on an hour with a capacity of 1 kW every day, then in a month it will wind up 7.5 kW of light in addition to your electricity consumptions.
This indicator may seem too large to you, but it is much lower than the consumption of light with an electric stove. Since the use of an electric stove or oven will cost 2.5 times more expensive. The microwave with electric kettle also consumes much more electricity.
Using a slow cooker, you will free yourself a bunch of free time, because it will be enough only to lay the necessary products, set the mode and return to the kitchen when the dinner is completely ready.
Energy saving tips
Although the slow cooker, as you already understood, does not take too much energy, nevertheless we want to give some tips for the most economical tips, how else you can reduce the electricity consumption of this kitchen machine:
- Choose models where the cooking occurs under pressure;
- Choose a program with the greatest automatic mode;
- Choose the mode of “stew” or “languor”;
- Do not use the “heating” mode after cooking the dish;
- Refuse to bake in electric breathing, switching to baking in a slow cooker.
Knowing your appetites and opportunities to cook at home, now you can easily calculate how much electricity will have to be spent on the use of a slow cooker. So it is easy to decide whether such an assistant in the kitchen is needed, or you will continue to be bent on an electric or gas stove, spending much more strength and energy to prepare dinner.
How much electricity is consumed
The heating canor consists of a small case, in which the fan and electric spiral are built. The process of work is very simple: the spiral heats up, and the fan spreads heat. Quite easy to handle and very quickly heats the room, due to the spraying of heat. But it has several disadvantages: a lot of oxygen is necessary, since the open spiral for heating burns oxygen; When working, the fan creates a lot of noise.
The fan can be turned off, but then the heating effect of the device is small. In addition, this will lead to rapid burning of the spiral, since it does not cool, which is dangerous.
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 the corresponding electricity consumption. Also, everything will be scored from the operating mode of the device, if it works in maximum mode, then the consumption is greater, if in minimum, then less.
Which affects the consumption of electricity by thermal talent
Thermal cores are one of the most popular types of heaters. This is affected by its compactness and what quickly heats the room. They are easily tolerated, easy to use and transport. You do not need special devices for their installation.
There are several types of thermal talents, which we will consider. Their consumption of electricity depends on both the model, capacity of the manufacturer, and purpose.
Based on species and design, they can be divided into species:
- thermal talents with a regulator;
- thermal talents with a regulator and armostat;
- Thermal talents for rapid heating of large rooms.
Thermal tanks with a regulator have several capacities and work depending on what is set. For example, in position 1 works with a power consumed by 500 W, in position 2–1000 W, and in position 3-1500 W. In modern models, there may be more power regulation provisions. The main disadvantage is a constant supervision of both the time to switch power, and then, so that it does not overheat. Nevertheless, it makes it possible to accurately calculate the energy consumption.
Thermal tanks with a regulator and thermostat represent a more complex design. It provides for the disconnection of the device from the network in case of overheating. Therefore, there is no need to constantly observe him. You can turn on and go about your business. The built.in thermostat allows you to turn off the heater, upon reaching the room in the room. To do this, just catch the moment of the temperature that we need and fix it on the thermostat. Its electricity consumption depends on various factors, primarily on the temperature to which the room should heat and then support this temperature. It is clear that the greater the difference between the initial temperature and the necessary, the more electricity will be needed. Allows you to choose several capacities, as well as several modes of operation fans.
Important! For the operation of thermal talents, normal air circulation is necessary! Therefore, you need to try to install the device in places where it is possible to do. Do not put close to the walls, furniture, desktop. In addition to the fact that with insufficient circulation of air, the heating of the room will be less, and therefore, the consumption of electricity is greater, this can lead to overheating of the spiral and its fire.
Thermal gun “heat gun” is used to quickly heat large rooms. For example, clubs, discos, conference rooms, rooms where people are not always gathered, and there is no need for constant heating.
When compared with the 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 consumes significantly the amount of electricity and is completely not suitable for household needs. Heating will be too expensive.
An example of calculating electricity consumption
Let’s try to calculate the maximum consumption of electricity. If the factory characteristics indicate that its capacity is 2000 watts, this means that in the maximum mode it consumes 2 kW in the maximum mode. In the winter, the approximate mode of operation is as follows: the hour works, and 2 is disconnected. Therefore, 8 hours will work per day.
28 and we get 16 kW of energy per day. If the average electricity price is 4, it turns out that the heating of the room within a day, you will cost 64 rubles. These are numbers for the maximum mode. In economic regimes, of course, the cost will be lower.
Thus, knowing the power of the heat.rector and the approximate time of operation, we calculate the cost of heating.
How to calculate the consumption?
To determine how much electricity the convector consumes, it is necessary to multiply the time of his work in the watch by power. The difficulty is that it is necessary to take into account only the time during which the heating element is included.
It will work continuously if the air in the room cools down at the same speed with which. This happens in the following cases:
- with a large difference in temperature. for example, if on the street.30 ° C, and in the room you need to support 25 °;
- if the room is poorly insulated;
- If the capacity is not enough (the area of the room is too large).
In normal mode, the convector works in short intervals, turns on for 15-20 minutes per hour to heat the air. In this case, in order to calculate the energy consumption per hour, the declared power must be divided into 3 (for 20 minutes of work) or by 4 (for 15 minutes of work). For a convector with a capacity of 1 kW/hour per 1 hour, it will be 0.333 kW or 0.25 kW. If the device is on constantly to get expense per day, this figure is multiplied by 24. To calculate the monthly consumption, the daily indicator is multiplied by the number of days in a month.
Consumption may vary depending on the air temperature on the street. In the cold, the convector will spend more energy.
How to reduce energy consumption by convector?
Several technologies are used for this. For example, some models (Polaris PCH 1094, Polaris PCH 1050 and others) have an aluminum heating element X-SHAPE, which provides effective warming up. Climate control functions, smooth temperature adjustment and the use of accurate thermostats in convectors Polaris PCH 2089D, Polaris PCH 1087D and others help to configure the optimal mode of operation: effective and economical.

An indispensable device that saves from communal workers with their preventive work. And it is not so voraciously. Convector devices consume up to 1.5 kW per hour. Oil. up to 1 kW. True, the latter are also terribly stinking, so saving is not always justified.
The owners of the boiler are not afraid of the repair of pipes in the summer. they will not wash in a basin. However, you have to pay for comfort. The average heater spends up to 2 kW per hour of his work. Catilers of a fluid type are even more voracious. they can spend from 3 to as many as 27 kW.
The most ordinary washer spends up to 2.5 kW in one hour of his work. over, most electricity is “eaten” at the time of boiling. So if you want to save electricity, it is better to turn on the machine in low.temperature modes.
The smallest, but surprisingly, one of the most gluttonous household appliances. For an hour of work, he is able to wind up to 3 kW of electricity! Steam devices are the most spent, because they need to get to the maximum temperature.
Electric plates are very popular among consumers. The number of electricity consumed by the device is influenced by the type of hob, which can be induction or het, the diameter of the firewood, the power and functionality of the device.
On a note! The induction surface consumes a smaller amount of electricity in comparison with the electric.
The power of the household appliance directly depends on the number of firewood and their diameter, which can be 14.5; 18 and 20. Accordingly, energy consumption is 1; 1.5 and 2 kW.
The capacity of the oven corresponds to 1.8-4 kW. The minimum power of energy consumption at one working burner is 1 kW. The maximum power of the electric stove is calculated taking into account the number of simultaneously working firewood, the operating mode of the oven. It can be 5-8.5 kW, as can be seen from the power table of household appliances and their power consumption.

To save electricity during the operation of an electric stove, some recommendations should be followed:
Elektracots are installed in houses for heating and heating water. However, behind the simplicity of the design and the ease of its operation hides a large consumption of electricity. The models of electric ships differ in power, design, the number of contours and the method of heating the coolant (heater, electrode or induction heating). Double.circuit boilers are used for heating and heating water. Boiler models are more economical than flowing.
The choice of the boiler is on the basis of the necessary power, which it must have in order to ensure the heating of the premises of a given area. When calculating, it should be borne in mind that KW is the minimum power of the device required for heating 10 kV.m.The area of the room. Additionally, climatic conditions, the presence of additional insulation, the condition of the doors, windows, floor and the presence of cracks in them, the thermal conductivity of the walls are taken into account.
note! The method of heating the coolant affects the final power of the electric boiler, while the electrode devices can heat a large area, while spending a smaller amount of electricity.
To determine the electricity consumption of the electric boiler, it is necessary to calculate the mode of its operation. It should be borne in mind that the device will operate at full power by half the season. The calculation is accepted the duration of his work per day. Thus, to determine the total consumption of electricity per day, it is necessary to multiply the number of hours by the power of the device.
To reduce the cost of energy consumption of the boiler, a two.phase counter should be set, according to which the calculation of electricity at night is carried out at a reduced tariff. Will also save the use of an automatic electrical appliance control device, which will control the operation of the device based on the time of day.
The correct location of the fan
It is very important to put the fan in the right place. For example, by placing it near windows or doors, you can significantly save electricity and money. The air coming from the openings will be well circulated, as it will be quickly picked up by the fan blades. You can turn on the device for an average or low speed (which was recommended above), but this will be enough for the maximum effect.
The choice of inverter fan
The inverter fan is slightly similar to an inverter air conditioner (also allowing saving electricity). By giving this purchase, you can count on saving thirty percent. However, it is worth taking into account the fact that the electric fan is quickly covered with dust, which settles on the blades. Such air can not only have an unpleasant odor, be ineffective for cooling, but also be dangerous to health.
Therefore, after the period specified in the operating manual, disassemble the fan. Rinse the front and back panels, as well as the impeller. Then collect the product and place it for a while in a cool place. After turning on, the effectiveness of cooling will be much more tangible.
