Difference between convector and heater. How to choose an economical electric convector for heating

When choosing a home heating system, it is important to choose the right devices that quickly and efficiently heat indoor air. Modern electric heating convectors are devices aimed at maintaining a comfortable temperature in a house or apartment.

They greatly facilitate the operation of traditional heating systems, and in certain cases can even replace them completely.

The operation of the device is based on the process of convection, associated with a well-known physical phenomenon: when heated, the density of the air decreases, as a result of which it expands and rises.

The name convector comes from the Latin convectio - “transfer”. The process consists of constant movement of air flows: cold air settles down, and warm air rises to the ceiling

The design of all types of electric convectors is extremely elementary. The main parts of the device are the housing and the heating unit located in the lower part of the casing.

Cold air enters the holes, which are located at the bottom of the device. When passing next to the heater, the temperature of the air flow increases, due to which it rushes upward, where there are outlet holes made at a slight angle.

In addition to the main elements modern models convectors also have many additional elements (overheating sensor, thermostat) that ensure comfortable operation

Warm gas rises to the ceiling, and then, gradually cooling, is nailed back to the floor, after which the stages of the process are repeated again. The constant movement of the air mass allows you to heat the room efficiently and evenly.

Strengths and weaknesses of electric convectors

The devices have their advantages and disadvantages. The popularity of such devices is explained by their many advantages:

Easy to install and operate. The devices do not require special preparation for operation or additional assembly operations. You just need to release the convector from the box and plug in the device.
High rate of room heating. The device quickly reaches the required power, since it does not have to waste energy to heat the coolant.
Durability. Although the warranty period for convectors from well-known companies is on average 5 years, in practice they can work flawlessly for 10-25 years.
High ratio useful action . Electrical devices have the highest efficiency among heating devices. For new generation models this figure can reach up to 98%.
Mobility. The devices can be easily moved around the apartment, installing them anywhere where there is access to an outlet. There are also models on wheels and options that allow for mounting on walls.
Affordable price. Prices for electric convectors are quite affordable. In addition, such devices do not require servicing (removing fuel residues, cleaning parts), which also helps to save money.
Safety. Heating devices do not negatively affect the microclimate of the room: they do not require oxygen to operate and do not dry out the air. The temperature of the outer shell of the devices does not rise above +40-60 o C, so when using them there is no fear of burns.
Possibility of temperature control. Modern models often have a special heating regulator, thanks to which you can maintain the most comfortable temperature in the room without allowing it to rise excessively.
Various Setting Modes. Most convectors are equipped electronically controlled, thanks to which you can set a specific air heating program.

In addition to a large number of advantages, the devices also have some disadvantages. You should know that convectors require a stable supply of electricity to operate. In addition, there should be an outlet within reach, as experts recommend avoiding the use of extension cords.

Such devices consume enough large number electric current, which can become a problem given the high cost of this resource.

Most convector models operate completely silently. Only some devices may produce slight crackling or clicking noises during operation.

At the same time, the high cost of wasted electricity is to a certain extent offset by the use of a special economical mode, which is provided in many models, as well as by programming the device to turn off at certain hours.

What to look for when choosing a device

The problem of how to choose the best electric heating convector is quite acute, since dozens of similar models are presented in specialized stores. The following technical characteristics are particularly important.

Heating element type

Convectors use various types of heating devices. The main ones include tubular, needle-shaped and monolithic.

Needle-shaped. The heating element of devices of this class is a thin plate made of dielectric with a chrome-nickel heating wire placed on it. For insulation metal thread, forming loops on both sides, is varnished on top.

Designs with such a device are low in cost, but are not very reliable, since the chromium-nickel element is characterized by instantaneous rapid heating and cooling. In addition, the type of insulation provided does not guarantee good protection against water splashes, which is why these devices are not recommended for use in bathrooms.

Tubular heating element(TEN). The most common models are characterized by the use of a steel tube, where, surrounded by a heat-conducting insulating material passes nichrome thread. Aluminum fins located on the heating element enhance convection, providing efficient heat transfer.

The tubular heating element can be open or closed. Protected heating elements are more durable and durable, they are well suited for use in wet areas

Convectors with heating elements have better technical characteristics than their needle counterparts: the former are less subject to heating, which makes them durable. Many devices have effective moisture protection, which allows them to be used in bathrooms. The disadvantages include crackling, which can occur due to different rates of thermal expansion of parts made of metals different types.

Monolithic heating element. Blocks of a new generation, the action of which is due to the heating of a solid cast base. Thanks to this detail, the devices are characterized by silent operation and high efficiency.

Power of electric convectors

The main characteristic on which the amount of heat produced by a convector depends is its power. When selecting a device, you need to keep in mind that 1 kilowatt is designed to heat a room of 10-12 m2 (with standard height walls 2.7 meters), where there are no other heating sources. If available central heating, this power is enough to heat twice the area, that is, 20-24 m2.

The power of convectors to a certain extent depends on their size. As a rule, large models show the highest indicators. At the same time, other characteristics also affect the heat transfer of devices, primarily the type of heating element

To correctly calculate power, a number of other factors should also be taken into account. With the same area of intense heating they will require:

rooms with many windows;
rooms located in the corners and ends of the building;
apartments located above basements.

When selecting a convector, you should also take into account which room the device is intended for. For example, for a kitchen, a device with a lower power rating is sufficient than required for a bedroom of similar size.

Instrument Size and Configuration

Manufacturers' lines include models with a variety of dimensions: the height of miniature versions starts from 15 cm, while the largest convectors can reach 2-3 meters.

Some models of electric convectors are specifically designed for children's rooms. They have an ergonomic design with rounded corners and maximum safety design

The collections include devices of various shapes; in addition to the usual rectangular and square models, you can find round, oval and other non-standard options.

Varieties of installation methods

There are several types of electric convectors depending on how they are used indoors.

Mobile and built-in (stationary). Mobile devices can be easily moved around the room within reach of the cord. For ease of movement, models of this type are often equipped with wheels.

Built-in- these are variants of convectors that are mounted in walls. A variation of this category are built-in floor options used for laying a “warm floor” system. All installation work similar devices must be carried out by qualified personnel.

Wall-mounted (hanging) also refers to stationary. They are fixed to the walls using special connecting elements.

Universal - devices that allow both installation on the floor and hanging on vertical surfaces, that is, they are inherently mobile.

Principle of device control

Electric convectors are often equipped with power regulators that allow you to set the degree of heating of the room, which eliminates unnecessary electricity consumption.

Modern devices may also have special blocks for programming settings on long period with an increase or decrease in temperature at certain hours. Such models are more expensive, but they reduce energy consumption.

Electric convectors can be equipped with two types of thermostats. Mechanical ones require manual setting of the required temperature, electronic ones allow you to use automatic mode

There are also devices whose settings can be changed using the remote control remote control. In this case, you can control the operation of the device from afar, which is located, for example, in a children's room.

Special and additional features

Almost all models of modern heating devices have special overheat sensors. When the maximum temperature is reached, the device turns off. The further algorithm of actions may be different for different options. Some convectors turn on automatically after cooling, while others can only be turned on manually.

Mobile devices may have rollover sensor. If accidentally dropped, the device automatically stops functioning. This mechanism is especially in demand if there are pets or small children in the house.

Some models have a sensor that provides protection of walls from freezing. Similar function is especially in demand if the device is planned to be used in countries with harsh climates and in premises for non-permanent residence.

A useful device may be timer for shutdown, thanks to which the device will automatically turn off at the selected hour.

Modern convectors often have display, where the mode and set air temperature are indicated. This device makes it easy to monitor the operation of the device.

Safety rules when using EC

Any types electrical appliances require compliance with certain safety rules. There are some restrictions for the use of convectors.

In good condition electrical wiring Heating convectors can be left unattended for some time, especially if the models are equipped with overheating sensors

Safety rules:

Under no circumstances should the appliance be covered or used as a clothes dryer.
It is not recommended to place the convector near an electrical outlet: minimum distance, on which the device should be located, is 0.8 m.
For rooms with a high content of water vapor, device models marked IP 24, indicating a high degree of moisture protection, are suitable.

In general modern devices have high level reliability and fire safety.

In addition to objective indicators, when choosing, you must also take into account personal preferences and specific requirements.

If you have a limited budget, pay attention to convectors equipped with mechanical thermostats. Although they have fewer functions than automatic devices, their cost is much lower, and you don’t have to deal with programming instructions.

Each convector panel must have an autonomous power supply, and the cable cross-section is determined by the power consumption (up to 1.5 kW, this value is 1.5 sq. mm, above - 2.5 sq. mm)

Manufacturers' product lines include models with different characteristics and prices. To avoid overpaying, carefully study them and compare them with your requirements. For example, to heat a small room, you should not buy an overly powerful device.

If a model with many settings and high technical characteristics is sold at a cheap price, it is worth finding out the reliability of the manufacturer and carefully reading the documents so as not to purchase a fake.

Conclusions and useful video on the topic

The video contains material about the criteria according to which a high-quality electric heating convector is selected, and also provides information about the most popular brands.

Modern models of electric convectors allow us to solve the problem of maintaining a comfortable temperature in the rooms. A properly selected device combines fast heating time, high power and energy saving technologies, as well as ease of use.

For every family, a modern convector is a personal source of heat that can be used in chilly autumn or during a protracted spring. When management company I haven’t turned on the heating yet, and the apartment is already cool and damp, then a comfortable solution would be to turn on the heater.

Buyers often ask about a universal heating device such as a convector: what is it? The device has a presentable body and a heating element; a special space in the lower part of the convector serves to draw in cold air into the room. The air is heated by a heating element and passes out through top part housings. It is designed in the form of blinds. Warm air rises towards the ceiling, after a while it cools and falls down, where it again enters the convector heating element. The gradual air circulation is main principle operation of a convector from any manufacturer.

When considering how a convector works, you need to know that after heating the room to a set temperature, it turns off for a while until the air cools down. The temperature sensor measures the temperature at the entrance to the convector almost every minute and transmits a signal to the thermostat. If the air has heated up to a predetermined level, the thermostat temporarily stops the functioning of the heating element, which is important when careful use electricity. The electric convector will also stop working if a foreign object hits it and blocks the exhaust area. warm air.

The true statement about the convector is that it is absolutely safe when it operates unattended.

All convector housings are reliably protected from moisture. They can be placed in the bathroom next to the shower stall; this is especially convenient in country houses, or use a wall mount. During installation, it is important to take into account the small gap of free space on each side of the convector. It is more convenient to mount such a convector under the window above the baseboard. This way it will work more efficiently. You can read more about choosing an electric convector.

To do this, you should choose a wall convector with a thermostat; it comes in two types:

Convectors as a personal heating system

Using a thermostat, they create an entire heat control system in country houses. To do this, place it in every room required quantity heaters, each of which is connected to the head unit - this will be a heating convector, having one thermostat for the entire convector chain. The thermostat can be set to a specific plan for heating the room. It is convenient to control such a system via SMS, reducing or increasing the temperature in the house before arrival - that’s what heating convectors are modern type in our lives.

What determines the silent operation of a convector?

To quickly heat the room, there are convectors with built-in fans. They warm up the air much faster, but operate with noise. They are used to heat a cold room after a long absence. As a rule, they do not leave it overnight. A conventional heater is enough to heat an area of 19-22 sq.m.; a 2 kW convector placed in the center of the room will effectively cope with this task.

This is the most convenient convector in terms of power, which has a number of properties:

If we talk about the quiet operation of a heating device, then we need to take into account that it depends on the heating elements.

Types of heating elements:

What types of convectors are there?

A real multifunctional appliance - this is what a convector is in modern life. You can program it to maintain a comfortable temperature, control it remotely, or use a vitamin C filter to promote health. They differ in power level and size, have a rich model range in which everyone will find their own heat source.

Models in elegant sizes

A wise decision for owners of premises with panoramic windows there will be an Elegant mini convector, having a modest size and pleasant view. Its copper-aluminum heat exchanger has copper pipes and ribbed aluminum plates, due to which the service life of the convector is increased significantly. In addition, the heating device is not sensitive to corrosion and is capable of maintaining the set temperature for a long time. The grille for releasing warm air is located on top, which enhances the quality of heating.

Universal convectors

The Santekhprom convector, produced using Russian technology, has successfully found its place among heating devices installed both in residential premises and in public places. What makes them extremely reliable is the presence of electric-welded pipes through which water moves quickly. Due to the excellent water flow rate, there is no danger of contamination or icing of the devices.

Among the advantages of heating devices it should be noted:

low body temperature, which protects against burns;
increased wear resistance;
equal heat distribution in all parts of the room;
the intended installation of a regulator for temperature control.

Another universal convector, Atlantic, is also suitable for heating in industrial institutions, kindergartens and country houses. Distinctive feature convectors have safety sensors; they turn off instantly if any problem occurs. The heater gently heats the air without drying it out. With an outer casing temperature of 60°C, the air will always be comfortable and clean. When dust particles settle on the heating element, there is no characteristic odor due to the low temperature.

Convectors to protect your health

Everything you need for healthy life Convectors from the Electrolux company combine the same properties; they are one of the best heating devices. A distinctive feature of such a model as the convector Electrolux ECH AG 2000 EF are the following parameters:

Electrolux heating devices not only heat the room, but also act as orderlies. An important decision I will buy an Electrolux convector for my family. During the cold season, they will not only provide a comfortable temperature, but will also prevent you from getting sick.

Convector-ionizer

The elegant and economical Ballu convector operates so quietly that it will not be detected. Its heating element has two powers when heating the air, while oxygen is not burned. The Ballu Enzo BEC EZMR 1000 convector, for example, is made in the form of a monolithic structure. After a few hours of operation, the convector transforms the air, saturating it with ions.

The easy-to-use convector is equipped with only the most necessary functions, including:

Convectors operating with maximum heat transfer

The ultra-precise, stylish Zanussi convector is capable of making a room comfortable in the shortest possible time by heating it to a given temperature. During its development it was used latest technology, which increased the volume of air taken in by the convector. In addition, the heating device operates silently due to the monolithic heating device.

Optimal heating of air in a minimum time is the basis for the operation of these convectors.

The Timberg convector is interesting to use and the reviews about working with it are the most pleasant. It has a sensor that sends a signal to turn off the device if, for example, it falls. An ultra-precise thermostat is built into its one-piece body. It has a function with overheating protection, which allows you to leave the convector unattended and go about your business.

Heaters that mercilessly stole oxygen from the air are a thing of the distant past. A heating convector needed in everyday life, what is it for human life, many people ask this question. Heating convectors are the most advanced devices for creating heat. They can maintain the temperature in your home without supervision and help during cold and flu season. Convectors simultaneously warm and disinfect the air, making it healthy. These are invaluable helpers who keep your home comfortable and take care of your health.

First, let's decide what the difference is between a heater and a convector, because many people consider these concepts to be identical.

Heater - a device equipped with a heating element, a mechanical thermostat and, in some cases, a fan. The purpose of this technique is to simply heat the air in the room without distributing the heat. This is a simple and cheap option for home heating devices.

A convector is, as a rule, a wall-floor heater, the principle of which is based on natural air convection. Often, the design of a wall-mounted unit provides the possibility of attaching special legs for floor installation of the convector. Convectors are usually flat and rectangular in shape. Inside such a heater there is a heating element, passing through which the cold air heats up and goes out into the upper slots of the convector.

Advantages of convectors

We all know where the warmest place in the room is - next to the radiator. But in the case of convectors, warm air circulates and is distributed throughout the room without creating significant temperature changes. This quality alone makes one look at convector heating systems with interest.

In modern convectors, not ordinary tubular heating elements are used to heat air, but monolithic low-temperature heating elements made of a special alloy. Warming up of such a heating element occurs faster than in a minute, and heat almost immediately begins to flow into the room, since energy is not wasted on preheating the device itself. Such convectors have very high efficiency - more than 90%.
In addition, modern convectors operate silently, they do not burn oxygen and do not dry out the air in the room.
Electric convectors from the world's leading manufacturers are very reliable and safe in terms of their electrical protection. The fact is that they were initially created not as household electrical appliances, but as elements of the main heating system. Electric convectors have become widespread in France since the 50s of the last century; they were produced by many factories, and they were actively introduced into the housing stock.

One of the leaders in this area is the French company Noirot. All convectors of this company meet the second - highest - class of electrical protection. No live part is in contact with the housing. These devices do not even require grounding. Moreover, they are well protected from moisture and can be used even in wet areas such as swimming pools.

Convectors are insensitive to voltage surges - a sore spot in Russian power grids. They operate normally at mains voltages from 150 to 242 V and have a multi-stage protection system.

Through the use of low-temperature heating elements, invented, by the way, by Noirot engineers, it was possible to achieve a low heating temperature of the housing - no more than 55°C. These devices can be placed directly on wooden walls, without any additional equipment!

The temperature to which the heating element of the heater is heated is of great importance. In conventional heaters it can be from 60°C to 600–700°C. And the lower it is, the better, since at high heating temperatures oxygen is burned and thus the main advantage of the convector is lost. French convectors Noirot (“Noirot”) boast low heating temperatures and high convector safety. The low temperature of the heating elements is compensated not only by their increased area, but also by the heater body.

Everything is known by comparison

It is also interesting to compare a convector direct electric heating system with an indirect one, powered by an electric boiler and using a coolant - water or antifreeze.

An important difference is due to the fact that the electric boiler always operates at the same power. To regulate the temperature in the house, it turns on and off periodically. Convectors are equipped with their own thermostat. They may not turn on at full power; in a cold room they will turn on more often than in a warm room. Therefore, the peak load on the power grid is smoothed out. By the way, electronic thermostats, installed on Noiro convectors, allow you to maintain the set temperature in the room with an accuracy of 0.1°C.

Another difference is that the convector system can be installed and connected by anyone with minimal DIY skills. In this case, the convector system does not require any maintenance at all. Once you have installed, connected and programmed the system, you can forget about it. And it will serve for a long time. In addition, it is possible to combine all convectors into a single controlled heating system.

By connecting all convectors with a control cable and connecting it to the wall control panel or adding special device- programmer - into one of the convectors, which becomes the leading one, we get an automatic heating system with different modes operation: economical (night), anti-freeze mode (for dachas in which people do not live permanently), etc.

Modern technologies for transmitting signals over a radio channel make it possible to control an unlimited number of convectors. The radio system does not require laying a control cable; it can be easily upgraded when renovating a home. Also, the control system for a convector heating system can be integrated into the “ smart home».
The direct electric heating system based on convectors is today one of the most efficient, convenient and safe of all electric heating systems.

Electric heating is distinguished by its simplicity and efficiency. It can be made on the basis of an electric boiler and radiators connected to it. Another option is to install autonomous electric convectors in the house and get rid of extra costs. What is a convector and how does it work? How effective and safe is it for others? We will talk about this in our review.

We will also tell you:

about the advantages and disadvantages of electric convectors;
about their structure and operating principle;
about power calculations;
about the criteria for choosing electric convectors.

In conclusion, we will introduce you to user reviews that will help you evaluate electric convectors under real operating conditions.

What is a convector

Heating devices can operate on two principles - radiate heat, heating surrounding objects, and create convection, ensuring air circulation in heated rooms. Convection allows you to quickly create comfortable environment in the house, carefully taking in cold air and generating warm air instead. Not only conventional radiators for water systems, but also electric convectors are built on this principle.

An electric heating convector is a small heater that resembles appearance the most ordinary heating battery. It operates from the electrical network and does not require a coolant supply. This achieves some energy savings and reduces heat losses. In order for the convector to work, you need to connect it to the mains - the most ordinary outlet will do for this.

The process of convection consists in the fact that the air heated by the radiator tends to rise, and cold air comes in its place.

The electric convector operates in autonomous mode. It does not require pipes throughout the house, an electric boiler, expansion tank and other devices necessary for water heating. The convector is designed to warm up the air and ensure its continuous circulation throughout the heated rooms. The result is high-quality and almost uniform heating of all rooms in the house or apartment.

What are the advantages and disadvantages of electric heating convectors? Why are they better than other heating devices? First we'll look at positive qualities this equipment:

effective heating of the room ensures comfort at any point - natural convection allows you to deliver warm air to any place in the room, displacing cold air from there;
fully autonomous operation– you don’t need to create a whole heating system, just hang it in the rooms required quantity convectors;
almost uniform temperature at all points after complete heating - this is ensured by natural convection and the reduced heating intensity of heating elements in modern convectors, resulting in a more uniform heat distribution;
compactness is characteristic of many modern heating devices. Thanks to this, electric convectors look good in any room;
the possibility of use as main or auxiliary heating equipment - if your heating is often turned off, you can purchase an additional heat source in the form of an electric convector;
no significant effect on air humidity and oxygen content – electric heating convectors do not burn oxygen and do not dry the air, maintaining a healthy and beneficial microclimate in the house;
instant start and complete silent operation - convectors heat up very quickly, and natural circulation air provides immediate heating of living spaces;
Extreme ease of installation - just place a wall-mounted model on the wall or install a floor convector. After this, you can start the convector and enjoy the warmth.

In addition, electric heating convectors do not require maintenance, do not require permits for installation, are safe for others and are characterized by high efficiency.

If it is possible to connect your home to gas communications, then heating system with fuel in the form of gas it will be much more economical than heating with electric convectors.

There are also disadvantages, which are listed below:

together with warm air, radiators carry dust, distributing it throughout all heated rooms;
despite the high efficiency, heating costs will be high. Electric heating is the most expensive heat source;
the cost of heating large households is too high - if you have a large house, it is more profitable to create a water heating system.

There are not very many disadvantages, so electric heating convectors can be considered almost ideal heating equipment.

Electric convector heaters will become great solution for small one-room and two-room households, as well as for small-sized country houses. They are also useful as auxiliary equipment for apartments.

Design and principle of operation

How are electric heating convectors designed and how do they work? If we disassemble the convector, then inside we will find a heating module with a heating element built into it, as well as a control module with a thermostat. Voltage is applied to the heating element, it begins to work and heat up, transferring heat to the air in the internal volume. The heated air rushes upward, exiting through the top vents. Cold air is taken in from below, from the floor.

There is nothing complicated in the design of an electric converter: a heating element with a control unit hidden behind a protective screen.

During manufacturing, electric convectors are placed in thin metal casings. Their maximum heating temperature is +60-65 degrees, so getting burned on them is problematic. As for heat transfer from the case, it is practically absent. But if we put our hand to the top ventilation grille, we will feel warm air flowing upward. Circulating throughout the heated room, it warms the people in it.

What is the operating principle of this equipment based on? Everything is extremely simple - natural air convection works here. The heating element warms the air, causing it to rush upward (obeying the laws of physics) and exit through the top vents. At the same time, cold air is drawn in through the lower grille. That is, electric convectors pass through themselves almost all the air in the room.

Natural convection allows you to do without the use of fans - this ensures quiet operation and softer and more uniform heating.

How to choose an electric convector

We have already figured out the structure of electric convectors, found out what certain parts of these devices are responsible for, and also talked about the principles of operation. Now we just have to figure out the issues of choosing equipment. Electric convector – which one is better? Let's figure out how to choose convectors and what you need to pay attention to when purchasing. There is nothing complicated about it, and after reading the material you will have all the necessary knowledge.

Installation method, dimensions

Choosing a convector should begin by studying the varieties. They are:

wall-mounted;
floor;
universal.

Floor-standing electric convectors will help you stay warm on cold summer days or during transitional seasons when central heating is not yet working.

Wall models are heating devices for permanent placement. They are mounted on free sections of walls or under window openings, providing quick heating of the room. Due to the light weight (there is no coolant or thick steel here), there is no need for powerful fasteners, and you can handle the installation yourself, without outside help. Wall-mounted electric heating convectors are useful in homes where there is no heating system.

Does the heating often turn off in your home? Then portable floor models will come in handy. They are installed anywhere in living rooms, providing additional heat generation. Floor-standing electric convectors are equipped with four legs and have good stability. Many models have wheels on the legs to make the heater easier to move.

Floor-standing models will be an excellent solution for heating private homes - if necessary, they can be folded into a car and taken back to the city if you are afraid of their theft in your absence.

Universal heating convectors are distinguished by the presence of removable legs and the ability wall mounting. They are convenient for easy transportation to any place in the house. When the need arises, they can be mounted on the wall. Have you decided that a convector is no longer needed in this place? Found that its power is too high? Simply remove it from the wall, set it on legs and move it to a more suitable location.

Calculate the required power

If you want to create a comfortable atmosphere in your home, then when choosing electric convectors you need to correctly calculate the power. Here you will find standard calculations, based on a base power of 100 W per 1 sq. m heated area. For colder regions, it is recommended to base a base power of 150 W per 1 square meter. m.

A simple table with which you can select the power of an electric convector required to heat your room.

Power calculations begin with calculating the area of heated premises. For example, for a room of 20 square meters. we need convectors with total power 2 kW. Moreover, it is best to install not one convector here, but two at once - this way you can achieve more uniform heating. Thanks to the wide power range, you can always buy the right electric convector.

Some manufacturers claim that their convectors can heat a larger area than similar devices from other brands. For example, individual models with a power of 2 kW are designed to heat 25 sq. m of living space. Take this into account when choosing an electric convector, but remember that manufacturers tend to exaggerate some numbers and values.

Buying an electric convector of suitable power is not a problem. But if you want to create a more comfortable atmosphere in your home, you should take into account the following factors in your calculations - window design, availability additional insulation walls and ceilings, quantity external walls, climatic features this area and much more. For example, ordinary blinds can partially compensate for heat losses, which can be closed in extreme cold, protecting you from the cold emanating from the windows.

Methods for adjusting temperature

Are you planning to buy electric heating convectors and have already thoroughly studied the features of their choice? Don't rush to the store. Electric convectors should not only be efficient and economical, but also easy to use. Therefore, we will consider another selection criterion - the type of control.

Mechanical control is distinguished by its simplicity, so convectors with such control will cost less than those assembled with electronic modules. It is a combination of a simple mechanical thermostat and a simple timer (sometimes without one). The spread in accuracy of mechanical thermostats is very large, so it will not be possible to set the exact temperature. But there is practically nothing to break here.

Electronic control is more progressive, but also more complex. Here is just a short list of its capabilities:

precise temperature setting - the setting step is from 0.5 to 1 degree;
quick temperature selection using buttons - no need to fiddle with knobs;
the ability to control temperature using a built-in digital display (LCD or LED);
the ability to set a heating program (available in models with advanced software control);
possibility of working on a timer.

Electrical control is very precise, so it is preferred. But its presence leaves its mark on the cost of the equipment - electric convectors with similar controls are expensive.

Some models are equipped with remote controls, allowing you to change heating settings without leaving the sofa. It is also impossible not to note the fact that electronic control allows for savings in energy consumption.

Convector safety

Electric convectors are safe for children and animals, since their outer screen does not heat up to dangerous temperatures.

Electric convectors are safe for children, adults and animals. The outer surface of their housing does not heat up above +65 degrees, and the heating element installed inside is reliably protected from external attacks. In addition, some models are equipped with protection against water splashes, which opens up the possibility of their use in bathrooms or kitchens.

The cheapest electric convectors are equipped with simple mechanical control modules. Their disadvantage is the possibility of overheating in the event of equipment failure. Models with built-in overheating protection are safer for others– when a certain temperature is exceeded, they automatically turn off. Additional security Electric heating convectors provide automatic shutdown systems if they fall.

Designer models are often decorated with glass. It would seem that the use of glass is not safe. But manufacturers thought of everything ahead, using special high-strength glass - they are not afraid of accidental falls and impacts, do not crack due to thermal expansion and do not harm others. If there are children in the house and you want to purchase stylish designer convectors with a glass panel, pay attention to models with high-strength glass.

Which electric convector is better

We have talked enough about the criteria for choosing electric convectors - all that remains is to finalize the final results. So, if you plan to constantly heat your home using convectors, pay attention to wall-mounted or universal models. Do you want ease of use and savings? Then you will like models with electronic control - such convectors are produced trademarks Noirot and NOBO (some of them are complemented by remote control functionality).

Undoubted ease of use will be provided by the automatic start function after a power outage - the convectors remember the last set operating mode. Thanks to this, you will not freeze after a sudden power outage.

Are you planning to use electric convectors for temporary space heating? You can save money by looking at simple floor models with mechanical control - these are sold in any stores selling heating equipment, since this product is in demand. They will provide good heating with minimal cash costs for the equipment itself.

Exists large selection designer electric convectors for unusual interiors.

Do you want to make designer renovations in your home, but you are rightly afraid that ordinary electric convectors will not fit into the interior being created? Then we recommend purchasing designer-type electric convectors. They come with decorative glass panels various colors which give heating equipment stylish appearance.

Did you know that heating can be not only efficient or economical, but also healthy? This is true - electric convectors with built-in air ionizers are available for sale. They will make the air in your home healthier, remove allergens and dust, and saturate it with healthy ions that neutralize free radicals in the human body.

Prices for electric heating convectors vary widely. Models with a power of 500 W cost from 900 rubles, and with a power of 1 kW - from 1,500 rubles. For electric convectors with electronic control and a power of 1000 W you will have to pay from 1700 rubles. Similar designer models cost from 2,300 rubles, depending on the power and impudence of the seller.

When choosing electric heating convectors, be sure to pay attention to manufacturers - buy equipment from famous brands, trying to avoid products from little-known brands.

To ensure a comfortable indoor temperature during the cold season, devices such as convectors and heaters can be used. What are the specifics of both?

What is a convector?

Convector, or “convector-type heater”, is a device that heats air by passing it through itself and thus mixing heated air masses and cold ones present in the room.

The main advantages of the convector: lightness (allowing, in particular, to easily mount the device on walls), relatively low level noise, efficiency of heating the room, absence of unsafe burning elements on the body.

The main disadvantages of a convector: the consumption of very large amounts of electricity, as well as the need to keep the device constantly on, since without moving warm air in the room, the temperature in the room can quickly drop.

It is worth noting that modern convector models are usually equipped with thermostats that deactivate the device when it reaches optimal temperature premises and turn it on again if it decreases. This allows you to save some electricity consumption.

The main elements of the convector design are a fan, a chamber and a heating element. By means of a fan, air from the room is directed into the chamber, quickly warmed up, and then immediately discharged back into the room. In this case, the output blinds of the convector, as a rule, are directed hot air down so that it has time to heat the lower part of the room before rising to the ceiling (due to its greater lightness than the air present in the atmosphere of the room).

What is a heater (oil type device)?

Under the term " heater", which is traditionally opposed to a convector due to the difference in operating principles, is most often understood as an oil heater. What are its features?

The convector, as we noted above, heats the air by passing it through itself. In turn, the oil heater functions like a heating radiator - that is, providing gradual heating of the entire volume of air present in the room.

The design of the device in question contains an oil reservoir. It contains a heating element. Oil in in this case performs the function of a coolant. Its most important useful property- ability to retain heat for a long time after heating.

The main advantages of oil heaters: no need to keep the device constantly on (due to the fact that once heated oil is able to maintain its temperature and at the same time the surrounding air for a long time), the ability to place the device anywhere in the room - however, only on the floor surface.

The main disadvantages of oil heaters: high temperature surface of the case, a fairly large mass, a very long time to warm up the device, a high level of energy consumption, uneven heating of the air in different parts of the room. At the same time, it should be noted that oil heaters equipped with fans are brought to full readiness quite quickly.

Comparison

The main difference between a convector and an oil-type heater is the principle of operation. The first heats the air by passing it through itself. The second one works like a heating battery, gradually heating the entire volume of air present in the room. The key difference between the devices under consideration predetermines all the others - in the uniformity and intensity of air heating, in the design, in the features of use.

What is better - a convector or an oil-type heater? First of all, both devices can be called equally energy-consuming. The convector, which itself has considerable power, must be constantly turned on. The oil heater, despite the fact that it can, as we noted above, turn off at for a long time, warms up for quite a long time, while also consuming a very decent amount of electricity.

The convector objectively has advantages in terms of speed and uniformity of air heating in the room, safety, and ease of installation. However, from a price point of view, an oil heater has an advantage: when comparing the cost of devices designed to heat rooms with the same area and produced to the same extent famous brands, you can see that the convector will cost 1.5-2 times more.

In terms of manufacturability, a convector is preferable to a heater; in terms of price, the situation is different. Regarding energy consumption, it is difficult to give preference to any of the devices based on this criterion.

Having studied the difference between a convector and an oil-type heater, we will reflect the conclusions in the table.
