Power calculation and selection of ITT convector convector
This coefficient must be multiplied by the total thermal power, and the result is divided by the heat transfer of one part.
Thus, the calculation of heating by the area of special difficulties does not represent. It is enough to sit a little, figure it out and calmly count. With it, each owner of an apartment or house can easily determine the size of the radiator, which should be installed in the room, kitchen, bathroom or in any other place.
If you doubt your abilities and knowledge, trust the installation of the system to professionals. It is better to pay to professionals once than to make incorrectly, dismantle and re.start work. Or do not do anything at all.
Which convector to choose for a private house
When choosing a heater for a private house, you must navigate:
- for equipment capacity;
- to the brand;
- on the type of control;
- for additional functions;
- on design features.
The electronic control of the carpet will also help you save, and the remote control bullet will add convenience to use.
We have already talked about the capacity of equipment and reducing thermal losses. As for the brands, we recommend buying products of well.known brands. it is better to overpay a little than to suffer from constantly breaking convectors from little.known manufacturers.

It is also advisable to choose electronic control electric convectors. Mechanical control is not particularly accurate, which entails additional heating costs. As for electronics, it provides compliance with a given temperature regime with an accuracy of 0.5 degrees. Thanks to this, the cost of electricity will be reduced.
Additional functions are timers, remote controls, the presence of a built.in air humidifier, work on a given program and much more. All these options slightly increase the cost of equipment, but provide comfort when operating
If you plan to heat a suburban dwelling, we recommend paying attention to freezing protection. this function will save electricity on those days when you are not at home (for example, you live outside the city only on weekends)
Another recommendation. buy convectors with the possibility of flooring. Thus, you can adjust the heating zone on particularly cold days with severe frosts. For rooms with designer finishes, we recommend buying devices with an attractive design, for example, with a glass front panel.
How is it customary to heat houses and apartments, in addition to the classic central heating batteries?
There are various methods of heating the house. We list the most relevant and popular.
Oil heaters. They are heated for a long time, but when they “go out”, they work as an ordinary battery. Enter each heating rating for a private house. But there are many minuses of oil heater. Oil often flows from such models, it is dangerous for these Bandur, and it is dangerous to touch them, which is critical for families with children.
Thermal talents. They can quickly heat the room, but consume a lot of electricity, they make a lot of noise, dry the air and often lead to the appearance of the smell of “burned dust”.

ARDest heating venture
Infrared heaters. Another answer to the question of how to warm the house with electricity. But rather exotic. they do not heat the air, but the surrounding objects, which in turn warm the air. However, infrared models are not particularly effective if it is necessary to feel heat when coming from a cold street. And they work weakly in rooms where there are many partitions.
Quartz heaters. They are now actively advertised, calling the most economical. But it is important to understand that there are no miracles. If the heater has a power of 400 W (compare with an ordinary convector or oil battery-there is a power of 1500-2000 W), in principle it will not warm the room in size of the size of the toilet in Khrushchev-3-4 sq.m. Quartz models may seem inexpensive and economical, but as a result you will have to buy 4-5 heaters for a regular living room, and these are already very big amounts. And the heat capacity of quartz is exaggerated. In general, do not go to advertising. For example, here in detail and with visual calculations it is explained why statements like “consume no more than 2.5 kW per day with a heating of 15 m3” have nothing to do with reality.

Heating convectors. We will talk about them separately, since this topic is worthy of the closest attention. Questions often come across questions, perhaps stupid, but still. “which is better. a heater or convector?””. So, the convector is the heater. precisely, as we have already figured out, one of the types of heaters for houses, apartments, cottages. And, in our opinion, the most optimal. So, if you still do not know which heating is better for both a private house and an apartment now in details will tell.

How convector heaters are arranged?
The convector is based on, as it is easy to guess, the principle of convection (air circulation) is a physical phenomenon that everyone studied at school. The device has holes in the upper and lower parts. Cold air is more heavy and therefore located in the lower part of the room. And when it heats up, it rises up (therefore, balloons fly). Thus, through the lower holes, cold air enters the convector, then heats up with a heating element and exits through the holes in the upper part, creating a comfortable temperature in the room. It turns out the correct, natural heating of the house. in fact, the air cycle in the room, since the cooled air masses fall down again and so on. The heating of the room occurs evenly, comfortable for households.
There is nothing complicated in the device device, except that the size of the heating element should be large, so the convector for the house is not miniature. Although the models are narrow and flat, unlike massive oil heaters.
Energy saving recommendations
Our houses lose a lot of thermal energy. So as not to overpay for electricity, just get rid of heat loss.
Engaged in calculations for area or volume, and without taking into account thermal losses, you risk getting an insufficiently effective heating system. it will be cool in the premises. Worst of all, if severe frosts are not very characteristic of the area in winter. if the calculations were made incorrectly, the convectors cannot cope.
Next, we will tell you how to reduce thermal losses. To reduce them by 10-15% will help the banal lining of the household with an additional layer of brick and thermal insulation. Yes, the costs may be large, but you must remember that when using electric convectors, the cost of light can be giant. this is associated with large thermal losses (in fact, you are heating the air “on the street”).
- Single double.glazed windows require an increase in power by 10%;
- Double windows do not lead to any heat loss (already plus);
- Triple windows save up to 10%.
Theoretically, windows of three glasses can lead to solid savings, but other factors must be taken into account.
In the process of insulation, it is necessary to work on the attic. All things are that the presence of an unheated attic entails loss. Therefore, you need to lay a layer of effective thermal insulation on it. it is not very expensive, but you can save up to 10% of thermal energy. By the way, an indicator is 10%, based on the area of the house in 100 square meters. m, this is about 24 kW of heat per day. equivalent to cash costs in the amount of 100 /day or 3000 /month (approximately).
Pros and cons
Recently, not only apartments have been equipped with electrical convectors with electric convectors, but also:
Electronic display convectors working from electricity have a number of advantages that are that they are:
- Easy to install and operate.
- Do not need special maintenance.
- Have a high service life up to 20 years.
- Ergonomic and silent in work.
- Have a high efficiency level up to 95%.
- Within 30 seconds after turning on, the room is heated.
The negative characteristics of these devices include:
In addition, the flow of warm air from electric convectors helps to spread dust through the room, which can cause allergic reactions in dependent people, asthmatics.
Calculation of the capacity of the convector for the room
When the calculation of heating convectors by area is obvious that the full capacity of the convector will directly depend not only on the type of room, but also on its area. If you find it difficult to choose the type of your room, multiply the area by forty. If the room already has heating, it is necessary to reduce the resulting value by about 1.5-2 times.
For with standard ceilings (about 2.5-3 meters), the calculation apartments are carried out according to a simplified formula: 100 watts of power are taken per 1 square meter, and for use as additional heating equipment-70 W as an additional heating equipment.
For the most productive heating of several rooms, it is advisable to install several small convectors, one in each room. They should not be the same power: for the main rooms, more power is taken, and for the corner and for the hallway. less.
The new models are equipped with thermostats that turn off the convectors when heating the room to a certain temperature, so you should not be afraid of excessive heating-even powerful convectors will turn off as soon as your stay in the room is comfortable in the room.
Advantages and disadvantages of electric convectors
It should be remembered that electric heating units are a technique that does not tolerate violations of safety rules. Do not cover the device or dry the laundry on it. Overheating of the apparatus will occur, and, at best, protection will work.
The outlet should be located on the side of the unit (on top is prohibited) at a distance of at least 100 mm from the case.
Only with proper operation of the convector can a comfortable and cozy atmosphere in the house guarantee.
Requires calculation of power. this is a prerequisite for creating an effective heating system. A device of this type perfectly replaces radiators, while saving a place in the room. The device of the convector, in which most of the heat transfer occurs due to the movement of heated air, gives the effect of faster and uniform heating.

Electric heating of the premises can always come to the aid of the main heating system, replace it in the autumn or spring period of the offseason, and in special cases. even become the main source of heat in the winter season. It all depends on what thermal power the acquired electric heaters possess.
Calculator calculator of the required power of the electric heater
Despite the wide variety of modern electrical heating devices. convectors, thermal tires, oil radiators, infrared emitters and t.P., power parameter for any of them is a determining. It is he who shows the operational potential that is laid down by the manufacturer in this product. So, before going to the store for buying, it is necessary to clearly imagine with what criterion of the assessment to approach the choice of a particular model. Will help in this. calculator of calculating the required power of the electric heater.
Below are some necessary clarifications in the procedure for calculating.
Calculator calculator of the required power of the electric heater
The calculator program is based on the features of the room in which the use of an electric heater is supposed to.
- First of all, it is necessary to decide which mission will be assigned to the device. whether it will only “help” for heating, or it is necessary to provide an option when the heater will have to cope with the function of the main heat source.
- The area of the room is the initial value for calculations.
- External walls. the more there are, the higher the total number of thermal losses, requiring a certain compensation.
- The walls on the northern and eastern sides almost never receive a “sun charge”, unlike the southern and southwest.
- Walls located on the windward side are cooled much faster than others. this is taken into account in the calculation algorithm.
- When indicating the temperature level, it should not be indicated recordly low indicators. this should be the value that is common for the region of residence, in the coldest decade of winter. Thus, the calculator will already take into account the existing climatic features.
- The degree of wall insulation. If thermal insulation work was carried out fully, on the basis of the heat engineering calculations, then the walls can be attributed to the category of qualitatively insulated. A brick wall of approximately 400 ÷ 500 mm thick, and similar to it, can apply for an average degree of insulation. The walls without insulation, in theory, should not be considered at all, since in such a room even with an inadvertently large consumption of electricity, a comfortable microclimate still cannot be achieved. The acquisition of an electric heater in such conditions becomes a meaningless venture.
- Ceiling height. affects the total volume of the room.
- The next two input windows are the nature of the premises located above and below the room in question. Naturally, the amount of heat loss through the upper and lower overlap depends on their features.
- Next. a block of fields regarding windows in the room. First of all, it is necessary to indicate the type of window. the calculator will take into account their heat.saving capabilities. Further, after indicating the quantity and size of the windows, the program will calculate the glazing coefficient (relative to the area of the room) and will make the appropriate adjustment in the calculations.
- Finally, the room may have one or even several doors used to go outside or in unheated rooms. Naturally, with each opening of such a door, a considerable volume of chilled air enters the room, which will require additional thermal power consumption.
The result is given in watts and kilowatts. According to these parameters, it will already be possible to evaluate the electric heater model that attracted in the store.
How to choose the right electric heater?
In addition to power, there are many other criteria for evaluating such devices. dimensions, safety in operation, ease of use, mobility, degree of automation and others. Read more about the aspects of the choice of energy.saving electric heaters. in the special publication of our portal.
Calculation of the required convector power
For a detailed calculation of thermal power, professional methods are used. They are based on the calculation of the amount of thermal losses through the enclosing structures and the corresponding compensation for their thermal heating power. Methods are implemented both manually and in the software format.
To calculate the thermal power of the convectors, the methodology of enlarged calculation is also used (if unwilling to contact the designers). The capacity of convectors can be calculated by the size of the heated area and the volume of the room.
A generalized standard for heating the built.in room with one outer wall, the ceiling height of up to 2.7 meters and a single glazing of the window is 100 watts of heat per square meter of heated area.
In the case of the angular location of the room and the presence of two external walls, the correction factor 1 is used.1, increasing the calculated thermal capacity by 10%. With high.quality thermal insulation, triple window glazing, the calculated power is multiplied by a coefficient of 0.8.
Thus, the calculation of the thermal power of the convector is calculated by the area of the room. for heating a room with an area of 20 kV.m with standard heat loss indicators, you need a device with a capacity of at least 2.0 kW. With the angular arrangement of this room, the power will be from 2.2 kW. In a qualitatively insulated room of equal area, you can install a convector with a capacity of about 1.6. 1.7 kW. These calculations are true for rooms with a ceiling height up to 2.7 meters.
The premises with a higher ceiling height use the method of calculation by volume. The volume of the room is calculated (the work of the area to the height of the room), the estimated value is multiplied by a coefficient of 0.04. When moving, the thermal heating power is obtained.
Using convectors in large rooms
According to this method, a room with an area of 20 square meters.m and a height of 2.7 meters requires 2.16 kW of heat for heating, the same room with a ceiling height of three meters. 2.4 kW. With large volumes of premises and a significant height of the ceiling, the estimated capacity in area can increase to 30%.
Power of heating convectors
This section of the article provides a table of selection of capacities of convectors depending on the area of the heated room and volume.
|Heated area, sq.m, the height of the room. up to 2.7 meters||Thermal power of the convector, kW||Thermal power of the convector (ceiling height.2.8 m)||Thermal power of the convector (ceiling height.2.9 m)||Thermal power of the convector (ceiling height.3.0 m)|
From the given table, you can choose a convector for a heated area. Heights are given in 4 versions. standard (up to 2.7 meters), 2.8, 2.9 and 3.0 meters. With an angular configuration of the premises to the selected value, it is necessary to apply an increasing coefficient of 1.1, during construction with high.quality thermal insulation. lowering 0.8. At the height of the ceilings of more than three meters, a calculation is carried out according to the above methodology (by volume using the coefficient of 0.04).
After calculating thermal power, the selection of heating convectors is carried out. the quantity, geometric dimensions and the installation method. When selecting devices in the rooms of large area and volume, it is necessary to take into account the characteristic and power of each individual convector power. It is necessary to be guided by the principle of increased capacity of the convector installed in the obstruction zone of maximum heat losses. That is, the device installed along the glass window of the full profile should have a greater value of thermal performance than the convector placed at a small window or outer wall.
Ways to determine the consumption of electricity with home appliances and tools
The average electricity consumption in the apartments of citizens for a month consists of the total consumption of electricity by all electrical appliances used by its residents. Knowing the consumption of electricity for each of them will give an understanding how rationally they are used. Changing the operating mode can give significant energy savings.
Heat Transfer: Convection Over Cylinders, Part II (21 of 26)
The total amount of electricity consumed per month in the apartment or house is fixed by the counter. You can get data on individual devices in several ways.
A practical way to calculate the consumption of electricity according to the power of the electrical appliance
The average daily electricity consumption of any home equipment is calculated by the formula, it is enough to recall the main characteristics of electrical appliances. These are three parameters. current, power and voltage. The current is expressed in amperes (a), power. in watts (W) or kilowatts (kW), voltage. in volts (c). From the school physics course, we recall what the electricity is measured-this is a kilowatt-hour, it means the amount of electricity consumed per hour. All technique for the house is equipped with shortcuts on the cable or on the device itself, where the input voltage and the current consumed (for example, 220 V 1 A) are indicated. The same data is necessarily present in the product passport. By current and voltage, the power consumption is calculated. p = u × i, where
Electric Convection Heating Explained
Substitute numerical values and get 220 V × 1 A = 220 W.
Further, knowing the power of the device, we calculate its power consumption per unit time. For example, an ordinary liter electric kettle has a power of 1600 watts. On average, it works 30 minutes a day, that is, ½ hours. We multiply the power during work and get:
To calculate the costs in the monetary terms, the result is multiplied by the tariff, for example, 4 rubles per kW/h:
0.8 kW/h × 4 = 3.2 calculation of the average fee per month. 3.2 30 days = 90.6
In this way, calculations are made for each electrical appliance in the house.
Calculation of the consumed electricity using wattmeter
Calculations will give you an approximate result. It is much more reliable to use household wattmeter, or an energy meter. a device that measures the exact amount of energy consumed by any household device.
- frozen consumption power at the moment and for a certain period of time;
- froze and voltage;
- Calculation of the value of the consumed electricity at the tariffs you included.
The wattmeter is inserted into the outlet, the device that you are going to test is connected to it. On the display, the parameters of the electrical consumption are displayed.
Measure the current strength and determine the power consumed by the household device, without turning it out of the network, allows current measuring ticks. Any device (regardless of the manufacturer and modification) consists of a magnetic circuit with a movable opening bracket, display, voltage switch and readings fixation button.
- Set the desired measurement range.
- Unscrew the magnetic circuit by pressing the bracket, get it by the wire of the test device and closed it. The magnetic circuit should be located perpendicular to the power supply.
- Remove the screen readings.
If a multi.core cable is placed in the magnetic circuit, then zero will be displayed on the display. This is because the magnetic fields of the two conductors with the same current compensate each other. To get the necessary values, froze is carried out on only one wire. It is convenient to measure the energy consumption through an extension extension, where the cable is divided into separate cores.
Determining energy consumption by electric meter
The counter is another simple way to determine the power of the household device.
- Turn off in the apartment everything that works for electricity.
- Fix the readings.
- Include the desired device for 1 hour to the network.
- Disconnect it, take away the previous readings from the received numbers.
The resulting number will be an indicator of electricity consumption by a separate device.
The calculation of the power of the convector
When choosing such a device, the main operational characteristic is the power. It is determined based on the size and configuration of the room in which it is supposed to install the heater. There are several approaches when determining the required power.
Based on the area of the room
It is generally accepted that for a room with one door, one window and a stream high equal to 2.5 m, 1 kW per 10 m2 of area is required. This approach is approximate and is subject to adjustment through correction factors (k). For example, if the room is located in the corner of the building, t. e. The external walls surround it on both sides, then when calculating power, the amendment K = 1.1 is applicable.
If the room has good thermal insulation, you can use a lowering coefficient equal to 0.8 or 0.9.
Example 1. It is necessary to calculate the power of the convector for installation in a room with an area of 25 m2, with low ceilings (about 2.5 m), located in the corner of the building with walls that have double thermal insulation. The room has one window and one door.
Then the power P will be calculated by the formula: p = 1 kW (25 m2/10 m2) 1.1 0.8 = 2.2 kW.
By the volume of the room
This approach allows you to more accurately determine the power of the device, t. to. It takes into account the height of the heated space. The meaning is that for heating each cubic meter of air requires 40 W device power. To determine the final value, the same coefficients are applicable that are described in the previous case. It is also worth clarifying the power value if there is more than 1 window in the room. each subsequent requires an increase in the power of the device by 10%.
Example 2.You need to choose the power for the living room located in the middle part of the building with well.insulated walls. In the living room, 2 windows, the height of the room is 2.7 m, the length is 7 m, and the width is 4 m.
As an additional heating source
If the house has a central heating, the power of which is not enough to maintain a comfortable temperature, the convector can be used as an additional heat source.
In this case, a power of 40 ± 10 watts is required for each square meter of area or for each cubic meter. 15–20 W.
Heating convector capacity. heating system
On this site tab, we will be able to choose the necessary components of the installation for the right cottage. Any knot is undeniably important. Therefore, the choice of each element of the system must be carried out competently.
The installation of the cottage heating includes some devices.
The heating scheme has a thermoregulators, fasteners, the pumps increase the pumps, collectors, fabs, pipes, tank for expanding the boiler, and the connection system.
The power of the heating convector
To select the thermal power of the convector sufficient for each room, you can follow the simple rule:
- In the room with one outer wall and one window of one kilowatt (1 kW) of the thermal power of the convector is enough for heating 10 kV.m. living space;
- If the room has two outer walls and one window, then for heating 10 kV.m. It is required to add 20%, it turns out 1.2 kW of thermal power;
- If the room has two outer walls and two windows, for heating 10 kV.m. 1.3 kW of thermal power required.
There are more accurate calculations of the required capacity of radiators. who are guided by experts, but for a rough assessment of the proposed simple method, enough. In this case, the battery calculation method can turn out to be slightly higher than necessary, but the quality of the heating system will increase (a more accurate setup and low.temperature heating mode is possible).
To work the calculation program, it is necessary to resolve active contents for this page
The power of the heating convector
Electric convectors are used both by the main sources of the heating of the building, and as additional heating devices. This moment when calculating the necessary power of the device is taken into account primarily. often, the device is an addition to a centralized or autonomous system, if the main heating does not provide the necessary temperature regime in some rooms.
The calculation of the heater power for each case is carried out according to various initial data.
Electric heating convector device.
For a more accurate calculation of parameters, it is desirable to know the heat loss of buildings structures where heaters will be installed. But if these values are unknown, you can use the reference books on heating systems.
In a generalized form, the calculation of the heater power is made according to the following coefficients:
- for premises with high.quality thermal insulation (standards of Scandinavia and Canada countries). 20 W/m 3;
- for objects with medium.insulation (insulation of structures with polystyrene, the use of double.glazed windows, etc. D.). 30 W/m 3;
- poorly isolated objects (according to existing standards for enclosing structures). 40 W/m 3;
- objects with minimal heat protection (hangars, warehouses, production facilities, etc. P.). 50 W/m 3.
Based on these data, it is accepted that for heating each 1 m 3 of rooms required an average of 40 W convector power, as the main heat source. To use the device as additional heating, the calculation is made with the values of the coefficient of 25-30 W/m 3.
Thus, the power of the convector for heating the room in generalized calculus should be equal to its volume multiplied by 40. For example, for a room with an area of 10 m 2 and a height of 3 m, a heater with a capacity of 10x3x40 = 1200 W is required. If there is a main heating system in this room, a device with a capacity of 10x3x25 = 750 W is required as an additional heat source.
For apartments with standard ceilings height (2.4-3 m) the heater is selected by calculating the simplified formula. For each 1 m 2 area, the required power is taken equal to 100 W, for additional heating, respectively, 70 W, respectively.
For an effective electric heating of several rooms, it is better to purchase a device of lower performance, but for each room. For interior rooms with one outer wall, the calculated parameters can be slightly reduced. For angular premises, their value must be increased.
For hallways and utility rooms, the temperature regime can be less comfortable, so the convector is permissible to install with less performance. Modern electric heaters are equipped with thermostats that turn off the device when a certain temperature is reached.
The use of more powerful convectors for altitude does not threaten excessive heating of air.
If the building in which you are going to install heaters has an old aluminum wiring, it should be replaced. Regardless of the cross section of the aluminum wire may not withstand the load of heating devices. If you do not have the opportunity to change the wiring yet, conduct a separate fishing line for a trimmer to sockets to connect the heaters.
The cable cross section is necessary for powering heating devices to find out from the employees of the electric networks. This will avoid imposing fines on their part in the future.
If you solve this issue yourself, when making a calculation, it should be noted that the minimum cross section of the wire for the outlet is 2.5 mm 2. For consumers with a total capacity of 9 kW, this value is 4 mm 2 2. Having mounted the wiring with a section size of 6 mm 2.
You will ensure the reserve of its reliability in the case of the installation of additional electrical appliances in the future.
The power of the heating convector
With the advent of cold weather, many people think about the additional heating of their home, cabinet or other place. One of the common ways to provide yourself with warmth is the purchase and installation of the convector (on installation technology).
What is a convector? This is the last development in technology that allows you to heat air in the room based on the movement of air masses.
The principle of operation is based on the entire known law of heat exchange. According to this law, cold air masses fall down, and warm air masses are understood to the top, thus creating circulation. According to the passage of some time, the lower cold layers heat up, thereby create the optimum temperature in the room.
Read more about the principle of work here.
Calculation of the heater power
There is a wide variety of formulas, tables for calculating and selecting the power of heaters, but no calculation can accurately determine the necessary power for each specific case. All of them give approximate selection results for standard conditions in which the room is located. What is understood by standard conditions?
- Air temperature that should be maintained in the room. Usually 20s is accepted for calculations.
- Standard thermal insulation of the house or premises, which is calculated based on the average seasonal air temperature.
- The room has a ceiling height of not more than 2 meters 70 centimeters.
- The room is one.story.
Not many people will arrange the temperature of the supported air in the room 20s. It can be much higher.
The average seasonal outdoor temperature differs from everyday temperature and is often significantly lower than the average value. In this case, the amount of heat secreted by heaters does not compensate for the incoming cold into the room. This situation is deplorable not only at the moments of low temperatures, but also in the future, since the room is cooled, underput heat. In all subsequent days, the heaters will have to warm up the room, and this may not take one day, and all this time it will seem that the room is cold.
In private houses, cottages, the height of the ceilings is from 3 to 5 meters. The higher the ceiling, the more hot air rises up and remains there, and an adult assesses the air temperature at the level of his growth, on average. 175 cm, and air at this level is much colder.
Not all modern premises intended for heating are one.story. For multi.storey premises with a common communicating space, calculations are significantly complicated. Warm air from the lower floor rises up and, to a greater extent, heats not the lower floor, but the upper.
With any calculation of power consumption, errors are allowed, so the choice of the selection method is only behind the user himself. You can offer a quick and universal way of calculation when at 10 kV.m select 1000 watts. Given that the height of the ceiling is about 270 cm. All other parameters can be adjusted during the operation of the heating system. over, there is a false idea of the fact that the 20 square meters installed in the room. m one 2000 watts heater will work more economically than four for 500 watts. Most likely the opposite, since a larger number of heaters will be more evenly and, accordingly, heat the entire volume faster.
NOBO convectors manufacturer recommends using tabular data on the selection of its convectors.
|The area of the room||The power of the convector|
|up to 10 sq.m||500 watts|
|8-15 square meters.m||750 watts|
|10-18 sq.m||1000 watts|
|15-22 sq.m||1250 watts|
|18-25 sq.m||1500 watts|
|22-30 square meters.m||2000 watts|
However, there are also rules for the correct and rational placement of convectors for heated rooms. Neglecting them, all the calculations made will diverge greatly with the real picture of the distribution of air temperature flows by heated volume.
- Convectors must be installed in places of the greatest flow of cold air: under the windows, along the continuous walls, which borders directly on the outer air and exclude installation on draft.
- At the height of the ceiling above 3 meters per meter of height, it is worth adding 25-30% of the heater capacity.
- With a two-story placement of heated rooms, which have a common space with a free air exchange from one floor to another, for the first floor you should select 25-35% more power for the first floor, and for the second floor 25-35% less.
Nobo convectors can be used as heat heating heating or as an additional temporary heating. If the room already has any method of heating, then when calculating the power of convectors from the total calculated power, it is necessary to subtract the power of the main heating devices, and by the remaining power to select convectors. But in any case, the way to calculate you choose.
