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

They make the job much easier. traditional systems heating, and in certain cases can even completely replace them.

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

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

The design of all types of electric convectors is extremely elementary. The main parts of the device are the body 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 rises, due to which it rushes upwards, where there are outlet holes made at a slight slope.

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

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

Strengths and weaknesses of electric convectors

The devices have their advantages and disadvantages. The popularity of such devices is due to their numerous advantages:

• Ease of installation and operation. The devices do not require special preparation for operation or additional assembly operations. It is enough just to release the convector from the box and plug the device into the network.
• High space heating rate. The device quickly reaches the required power, since it does not have to spend energy to heat the coolant.
• Durability. Although the warranty period of convectors from well-known companies is on average 5 years, in practice they can work flawlessly for 10-25 years.
• High efficiency. Electrical devices have the highest efficiency among heating appliances. For new generation models, this figure can reach up to 98%.
• Mobility. Devices can be easily carried around the apartment, installing them anywhere where there is access to a power outlet. There are also models on wheels and options that provide the possibility of mounting on the walls.
• Affordable cost. Prices for electric convectors are quite budgetary. In addition, such devices do not require maintenance (removal of fuel residues, cleaning of parts), which also contributes to cost savings.
• Safety. Heating devices do not negatively affect the microclimate of the room: they do not need oxygen for their operation, they do not dry the air. The temperature of the outer shell of the devices does not rise above + 40-60 ° C, so when using them, you can not be afraid of burns.
• Temperature control capability. In modern models, there is often a special heating controller, thanks to which it is possible to maintain maximum temperature in the room. comfortable temperature without allowing it to increase too much.
• Various setting modes. Most of the convectors are equipped electronic control, thanks to which you can set a specific heating program.

Apart from a large number advantages, devices have some disadvantages. You should know that a stable supply of electricity is necessary for the operation of convectors. In addition, there should be an outlet within reach, as experts recommend avoiding the use of extension cords.

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

Most models of convectors work completely silently. Only a few devices may make slight crackling or clicking noises during operation.

At the same time, the high cost of electricity consumed 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 specifications are of particular importance.

Heating element type

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

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

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

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

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

Convectors with heating elements have better technical characteristics than needle counterparts: the former are less exposed to heat, due to which they are durable. Many devices have effective moisture protection, which allows them to be used in bathrooms. The disadvantages include cracking, which may occur due to various indicators thermal expansion parts made from different types of metals.

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

Power of electric convectors

The main characteristic on which the amount of heat produced by the convector depends is its power. When choosing a device, you need to keep in mind that 1 kilowatt is designed for heating a room of 10-12 m 2 (with standard height walls 2.7 meters), where there are no other sources of heating. If there is centralized heating, this power will be enough to heat twice the area, that is, 20-24 m 2.

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

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

• rooms with a large number of windows;
• rooms located in the corners and ends of the building;
• apartments located above the basement.

When choosing a convector, you should also consider which room the device is intended for. For example, for a kitchen, a device with a lower power rating is enough than is required for a bedroom of the same size.

Instrument size and configuration

In the lines of manufacturers, models are presented that have a variety of dimensions: the height of miniature options starts from 15 cm, while the largest convectors can reach 2-3 meters.

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

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 mounting methods

There are several types of electric convectors according to the way they are used indoors.

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

Embedded- these are variants of convectors that are mounted in the walls. A variation of this category are floor built-in options used for laying the "warm floor" system. All work on the installation of such devices must be carried out by qualified specialists.

Wall (suspended) also refer to stationary. They are fixed on the walls with the help of special connecting elements.

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

Instrument control principle

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 for a 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 require manual installation required temperature, electronic - allow you to use the automatic mode

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

Special and additional features

Almost all models of modern heating devices have special overheating sensors. Upon reaching maximum temperature the device turns off. Further algorithm of actions different options may be different. Some convectors automatically turn on after cooling, while others can only be turned on manually.

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

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

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

Modern convectors often have display, where the mode and the set air temperature are indicated. Such a device contributes to convenient control over the operation of the device.

Safety rules when using CI

All types of electrical appliances require compliance with certain safety rules. There are some restrictions on 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 regulations:

• Under no circumstances should the appliance be covered or used as a clothes dryer.
• It is not recommended to place the convector next to 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 with an IP 24 marking are suitable, indicating a high degree moisture protection.

On the whole modern devices have high level reliability and fire safety.

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

If you have a limited budget, pay attention to convectors equipped with mechanical thermostats. Although they have fewer features than automatic devices, however, their cost is much lower, and besides, you do not have to deal with programming instructions.

Each panel of the convector must be self-powered, while the cable cross-section is determined by the power consumption (up to 1.5 kW, this value is 1.5 sq. mm, over - 2.5 sq. mm)

In the lines of manufacturers, models of various characteristics and price are presented. In order not to overpay, carefully study them and compare them with your requirements. So, for example, to heat a small room, you should not buy an overly powerful device.

If a model with many settings and high technical specifications is sold at a cheap price, you should find out the reliability of the manufacturer and carefully read 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, as well as information about the most popular brands.

Modern models of electric convectors allow you to solve the problem of maintaining a comfortable temperature in the rooms. The right device combines fast time heating, 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 a chilly autumn or a long spring. When Management Company has not yet turned on the heating, and the apartment is already cool and damp, then a comfortable solution would be to turn on the heater.

About a universal heating device such as a convector, what is it - buyers often ask a question. The device has a presentable body and a heating element, a special space in the lower part of the convector is used to take cold air into the room. The air is heated by a heating element and enters the outside through upper part corps. It is framed in the form of blinds. Warm air rises towards the ceiling, after a while it cools down and falls down, where it again enters the heating element of the convector. The gradual circulation of air is main principle operation of a convector of any manufacturer.

Considering the question of how the convector works, you need to know that after heating the room to a predetermined 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 is heated to a predetermined level, the thermostat temporarily stops the operation of the heating element, which is important for the careful use of electricity. The electric convector will also stop working if a foreign object gets on it, blocking the outlet area warm air.

The true statement about the convector is that it is absolutely safe when it works without supervision.

All cases of convectors are reliably protected from moisture. They can be placed in the bathroom next to the shower, this is especially convenient in country houses, or you can use a wall mount. During installation, it is important to take into account the small clearance of free space on each side of the convector. It is more convenient to mount such a convector under the window above the plinth. So he 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 can be of two types:

Convectors as a personal heating system

With the help of a thermostat, they create a whole heat management system in country houses. To do this, place the required number of heaters in each room, each of which is connected to the head unit - this will be the heating convector, which has 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 - this is what heating convectors are modern type in our life.

What determines the silent operation of the convector

For the speedy heating of the room, there are convectors in which fans are built-in. They warm up the air much faster, but they work with noise. They are used to heat a cold room after a long absence. At night, as a rule, do not leave. An ordinary heater is enough to heat an area of ​​19-22 sq.m., a 2 kW convector located 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 the heater, then it must be borne in mind that it depends on the heating elements.

Types of heating elements:

What are convectors

A real multifunctional technique - that's 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. differ in power level and size, have a rich model range where everyone will find their own source of heat.

Models of elegant sizes

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

Universal convectors

Produced by Russian technology The Santekhprom convector has successfully found its place among the heating devices installed both in residential premises and in public places. Extremely reliable makes them the presence of electric-welded pipes, through which there is a rapid movement of water. There is no danger of contamination and icing of the instruments due to the excellent water flow rate.

Among the advantages of heating devices should be noted:

1. low body temperature, which protects against burns;
2. increased wear resistance;
3. equal distribution of heat in all parts of the room;
4. the intended setting of the regulator for temperature control purposes.

Another universal convector Atlantic is also suitable for heating in industrial facilities, kindergartens and country houses. hallmark convectors are safety sensors, they instantly turn off in the event of any malfunction. The heater gently heats the air without drying it. 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 smell due to the low temperature.

Convectors on guard of health

All the properties necessary for a healthy life are combined in Electrolux convectors, these are one of the best heating devices. A distinctive feature of such a model as the Electrolux ECH AG 2000 EF convector are the following parameters:

Heating appliances Electrolux not only heat the room, but also act as orderlies. An important decision to buy an Electrolux convector for a family will be. In the cold season, they will not only give a comfortable temperature, but also prevent you from getting sick.

Convector - ionizer

Elegant and economical convector Ballu works so quietly that he can't find himself in anything. Its heating element has two capacities for heating the air, while oxygen is not burned. The convector Ballu Enzo BEC EZMR 1000, 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.

Easy to operate, the convector is equipped with only the most desired functions, among which:

Convectors operating with maximum heat output

The ultra-precise stylish Zanussi convector is able to make the room comfortable in the shortest possible time by heating it to the desired temperature. During its development, the latest technology was used, which increased the amount of air taken in by the convector. In addition, the heater operates silently due to the monolithic heater.

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

The Timberg convector is interesting in operation. Reviews about working with it are the most pleasant. It has a sensor that gives a signal to turn off the device if, for example, it has fallen. An ultra-precise thermostat is mounted in its one-piece body. He has a function with overheating protection, which allows you to leave the convector unattended and go about your business.

Gone are the heaters that mercilessly stole oxygen from the air. A heating convector necessary 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 keep the temperature in the house unattended, help during the cold and flu season. Convectors simultaneously warm and disinfect the air, they make it useful. These are invaluable helpers who keep comfort in the house and take care of health.

A convector is a heating device in which thermal energy is transferred from a heating element or coolant to a heated room using convection. The essence of natural convection is that, from contact with a coolant or heating element, air rushes up - since it is lighter, heavier masses of cold streams take up the vacated space. Thus, constant air circulation is ensured, which is enhanced by the design of the convector, without additional mechanical devices.

In modern conditions, the length of an average family, a convector is a device that allows you to warm up an apartment in cold weather during the off-season (early autumn and late spring). When the heating season has already ended or has not yet begun, and the temperature has already become too low, an individual heater such as a convector will be an ideal choice. According to customer reviews, the convector is preferable.

This equipment is versatile, but not everyone knows about its incredible efficiency. The convector is equipped with a heating element and an attractive housing, and the area at the bottom of the device is designed to take cool air from the room.

To heat the air in the convector, a heating element is used, and then heated, it goes out through the top of the housing, which looks like blinds.

The heated air soars up to the ceiling, and after a certain period of time it cools and descends downward, where it is again sucked in by the equipment. The phased circulation of air is the basic principle of the operation of each electric convector, regardless of the manufacturer. The gas convector works in the same way.

The principle of operation of the electric convector

Convector and safety issues

The operation of the device is quite simple: after the room has warmed up to the temperature set by the user, the convector is turned off for a certain period - until the surrounding air cools down again. It has a temperature sensor that measures the temperature almost every minute and sends command signals to the thermostat.

As soon as the air warms up to the set level, the thermostat stops the heating element for a while, which reduces energy consumption and saves on electricity bills. A complete cessation of the convector's operation occurs only in a situation where a foreign object enters it, covering the outlet area of ​​heated air.

The convector can be safely left switched on unattended.

The casing of the convector has excellent protection against water penetration, so the device can be installed even in the bathroom, which is extremely convenient in country cottages, or mounted on the wall. During installation, small gaps should be left on both sides of the appliance. Most convenient option convector fastenings - under the window sill above the plinth. This will increase the efficiency of his work.

Wall convectors equipped with a thermostat are divided into 2 types:

• With electronic thermostat. The main advantage is the quiet operation. Disadvantages - high cost, sensitivity to power surges.
• With electromechanical thermostat. The advantage is immunity to voltage drops, the only drawback is a large error in temperature measurement.

Individual heating with a convector

The presence of a thermostat allows you to create a complete heating system in a country cottage. To do this, the required number of heaters is installed in all rooms and connected to the main device - a convector, which has the only thermostat in such a circuit. Further, if desired, the thermostat is adjusted to a specific mode of heating the house.

To control such a system, you can send SMS from your phone to lower or raise the temperature in the premises before the arrival of residents. And this is not all the possibilities of convectors produced today.

Convector control via app or SMS messages

Factors affecting the noiselessness of the convector

Equipment with built-in fans is designed to quickly warm up the house. They heat up the interior much faster, but their work is accompanied by noise. They are used to warm up the building after a long absence, but at night they are most often turned off. An ordinary convector with a power of 2 kW, located in the middle of the room, is enough to warm up 19–22 m 2.

This is the most practical option electric convector, which has a number of advantages:

• it is impossible to burn yourself about it, so it is safe for children;
• it can be left on unattended, because at the slightest failure it instantly turns off;
• can work in the mode of maintaining the temperature level selected by the user;
• has an attractive appearance, suitable for any interior;
• some models function completely silently.

The noise level of the heating convector is determined by the specifics of its heating components.

There are the following types of heating elements:

• Needle - looks like a plate of dielectric material, on which a heating thread is applied, forming loops from each edge of the plate. These loops can instantly warm up and cool down. This is a rather dangerous variety, since the loops are not protected from water. Similar convectors are used in industrial enterprises. They are inexpensive, but break pretty quickly.

• Tubular - equipped metal tube with a nichrome thread attached inside. The area between the tube and the thread is filled with insulating material. Heat exchange is carried out thanks to aluminum fins attached to the tube. This type of convector is distinguished by noisy operation, accompanied by erratic clicks due to different thermal expansion at the fins and the tube. However, such equipment can be installed in the kitchen or bathroom, as it is equipped with water protection.

• Monolithic - is installed in electric convectors, which are distinguished by complete noiselessness of operation and, as a result, are very popular with consumers. This heating element minimizes heat loss and guarantees maximum heating efficiency.

Varieties of convectors

At domestic use the convector can show itself as a truly versatile piece of equipment. It can be programmed to maintain a certain temperature level and is suitable for remote control. You can also install a filter containing vitamin C for healing.

Today manufacturers produce wide range of, differing in terms of power and dimensions. Also, a gas convector is suitable for installation in a country house.

Small models

Owners of apartments with panoramic windows should install "Elegant Mini", which has small dimensions and a presentable appearance. It is equipped with a copper-aluminum heat exchanger containing copper pipes and aluminum finned plates, which greatly increases the service life. uninterrupted operation equipment.

Such a convector is not subject to rust and can maintain the desired temperature level for a long time. The heated air outlet grill is located at the top, which increases the heating efficiency.

A large niche in the heating equipment market is occupied by convection household heaters - reliable and constantly improving units, differing in design, but united common characteristic- use of convection for space heating.

Let us consider in more detail convector heating, the most common types of convector heaters , their pros and cons, including in terms of the effectiveness of the application for heating housing.

The phenomenon of convection

One of the conditions for the comfort of staying in the room is the temperature regime corresponding to the purpose of the room. If it's about winter period, then it implies the need to warm the air in the housing to a certain temperature value, which is achieved with the help of household heaters.

From existing ways heating air in residential premises are those that do not have a negative effect on humans and do not create a fire or explosion hazard. For example, heating a living room with the heat of an open flame of a fire is not acceptable for obvious reasons, but the same fire in a fireplace or stove will heat the walls of the furnace, which will give off heat to the air in the room, and this method of heating a home is widespread.

To increase the temperature in the room, it is necessary to contact the air with a hotter object than it, which will transfer heat to it - heat exchange. This is achieved in two ways:

• an object (a heat exchanger in the design of a heating device) is heated by converting the energy of the coolant into heat - burning fuel or passing electric current through a conductor with high resistance;
• objects and enclosing structures in the room are heated by the radiation of infrared heaters and become heat exchangers - heat sources.

In both cases, so-called convective currents, causing convector heating. Air, in contact with hot objects, heats up and increases in volume. Since the heated air has a lower density value, it rushes up, being replaced by cold air.

When stable high temperature heat exchanger, this process occurs continuously and is called convection.

What is convection in heating. Heated air moves from the radiator-heat exchanger or objects heated by infrared radiation upwards, and cold (cooling hot) downwards. Liquids behave similarly when in contact with a heat exchanger, therefore their circulation during heating is also called convection.

Types of heating convectors

Any convector-type heater has a long list of characteristics, primary and secondary:

• type of energy carrier used to heat the heat exchanger;
• heat dissipation power;
• degree of automation equipment;
• security class;
• design execution at the place of installation;
• mobility;
• dimensions;
• decoration class.

According to this list, heating convectors can, if desired, be divided into many subspecies, but for practical application no such breakdown is necessary.

Since it is not easy to choose a convector heater among dozens of types offered by manufacturers, we will consider the main groups of these units that combine equipment according to the main parameter - the type of energy carrier.

Water convector heaters

Heating convectors using water as a heat carrier are popular due to their safety and ease of operation - no substances are released during the operation of these units, and their use does not require special knowledge and skills from the consumer. The most common example of such devices is water heating radiators connected to a central or autonomous heating system.

Water convector heaters are a radiator-heat exchanger with water (antifreeze), smooth or finned - to increase the heat transfer area. There is no heating element in its design - hot water circulates through the radiator, which is an element of the heating circuit, and heats its body. The air masses in contact with the body heat up and rise upwards, forming convection currents.

Such water heating convectors can be represented by familiar cast iron radiators or similar in size, but more advanced bimetallic devices with a double case.

A cast-iron prefabricated sectional radiator is reliable and durable, but inferior to bimetallic convectors in terms of efficiency and aesthetics.

Important! Cast iron radiators are also made of high-class artistic performance, but their price is ten times higher than the cost of standard models.

Bimetal water convectors are a steel tank placed in an aluminum shell.

The inner steel tank can withstand the coolant pressure well, and the outer shell and aluminum fins provide better heat transfer.

More compact heating appliances convective action are skirting board water convectors, which are modern devices based on copper pipes with fins made of aluminum plates mounted on a supporting base and decorated with a decorative outer panel.

Despite the compactness, the dimensions are still disproportionate more sizes skirting boards, so they owe their name, rather, to the place of installation - along the walls at a short distance from the floor.

The improved baseboard-type water convector radiators are equipped with a fan that accelerates natural convection.

Water convectors also used for heating of premises of significant dimensions - industrial, utility and auxiliary, but these are units of much higher power, in which the level of decorative performance fades into the background.

The power of water convectors for the possibility of heating rooms of a large area is increased by increasing the dimensions of the radiator, including the diameter and length (configuration) of heat conductors, and the area of ​​​​finning.

Important! In the heating system of seasonal residences, antifreeze is used as a coolant to avoid defrosting of the circuit. The use of water obliges to empty the system before the onset of frost.

Electric convection heating units

In second place in terms of prevalence of application are electric convector household heaters. Their popularity is also justified - the operation of electric convectors is not accompanied by factors harmful to humans, does not require fuel procurement, as well as additional room equipment with a chimney and exhaust hood.

By and large, these units include oil coolers, and wall-mounted monolithic decorative stone-like panels, and picture heaters, and many more devices that run on electricity and initiate the occurrence of convective flows in the room. These devices have individual characteristics, and therefore each of them needs to be considered separately.

In this article, we will consider the type of electrical appliances, which is most often called a heater in everyday life. -electro convector.

The main differences between the models of such electric convectors are the power and the degree of mobility (installation method). Wall-mounted and built-in devices have brackets for static attachment to the base, floor devices have support stands or wheels for ease of movement, skirting boards have brackets or stands (depending on mobility).

Device

Heating electric convectors consist of a metal case, called a convection chamber, and a heating element installed in it. The heating element is mounted without contact with the body, so there is no need to ground the heater.

For safety reasons, between the heating element and the walls of the housing there is a heat-shielding shell made of heat-resistant plastic, which reduces the surface temperature of the device to safe values. The room is heated by natural convection initiated by the heater - there is no fan in the design of the device in order to ensure its noiseless operation.

1 - front panel, 2 - deflector (static or adjustable) for the removal of heated air, 3 - switch, 4 - temperature controller control, 5 - thermostat electronic board, 6 - heating element closed type, 7 — temperature sensor.

Temperature control methods

The convectors are equipped with thermostats (mechanical or electronic), which turn the heater on/off according to the signals from the temperature sensors.

Mechanical thermostats work in tandem with a temperature sensor on the case, which monitors only the heating of the device, without reference to the air temperature in the room.

Advanced models of convectors are completed electronic thermostats, tracking, in addition to heating the case, and the temperature regime in the room - according to the signals of the sensors installed in the room. Such devices allow you to maintain the temperature manually set by the consumer in the room with fluctuations in magnitude of no more than 1 degree. If there are several such convectors in the room, a common electronic control unit is installed that regulates the temperature regime according to the signals of the temperature sensors by turning on / off and adjusting the power of all heaters.

The mechanical thermostat allows you to set the temperature in the room by trial setting values ​​on the regulator, increasing or decreasing the intensity of heating. The electronic thermostat sets the numerical value of the air temperature.

Depending on the performance class, electric convectors can be equipped with other useful options that increase the convenience of controlling the device and the characteristics of the air environment:

• a timer that automatically turns the heater on and off at the time specified by the consumer;
• a device for humidifying the air in the room to neutralize the operation of the heating element;
• remote control system with wireless remote control;
• light indication of working devices.

Advantages and disadvantages of electric convectors

Convector heating with electric units is widespread due to the predominance of the advantages of these devices over the negative characteristics.

Pros:

• ease of alerting and operation - plugging the cord into a power outlet;
• minimum participation of the consumer in the heating process;
• no need for special maintenance and preventive maintenance;
• noiselessness in work;
• durability - 10 years or more;
• availability of the price range;

Minuses:

• the significance of the energy consumption of all models;
• use as the main means of heating is possible only with the thoughtful installation of several heaters;
• combustion of dust on open heating elements is accompanied by an unpleasant odor.

Important! thick layer dust accumulated on the heater when the heater is turned on can cause a fire.

The described electric heaters of convective action are not pure convectors. The heating element, in contact with the air, initiates the movement of convective currents in the room, but at the same time it also heats the body of the unit. Any hot object is a source infrared radiation, the intensity of which depends only on the temperature of the emitter, so electric convectors are, to some extent, infrared heaters, heating objects by exposure to infrared radiation, but the participation of these rays in the heating process is very small.

Convective infrared heaters

These advanced electric convectors are units whose efficiency has been increased by increasing the proportion of heating provided by infrared radiation.

So convectively infrared electro a heater is a unit for combined heating of a room, that is, with the excitation of convection and the simultaneous use of infrared radiation.

The main "highlight" of convective infrared devices is the presence of two heating elements in the heater. It can be two identical heaters with a special coating that enhances the intensity of infrared radiation, or a pair of devices different principle actions - heating element and radiating panel.

The unit with two identical heaters has a perforated front panel for maximum IR penetration. In convectors with heaters different type The source of infrared waves is a radiating panel under a black decorative cladding - to enhance the radiation intensity.
1 - electronic control unit; 2 - all-metal cast heating element that initiates air convection; 3 - shock-resistant front panel with plate emitters of IR waves.

Advantages and disadvantages of a convective infrared heater

Pros:

• durability and functionality - if one of the heater fails, the device, albeit with less efficiency, can continue to be used;
• higher efficiency than conventional electric convectors
• rapid heating of rooms.

Minus:

• relatively high cost - from 5 thousand rubles.

Gas convector heaters

A convector-type gas heater is a device for space heating, the principle of which is based on heating the air flow when it passes through a recuperative heat exchanger heated by combustion products of gas, liquefied or natural.

Convector heating with a gas heater is carried out as follows - gas is supplied to the burner in a closed-type combustion chamber and ignited from a burning igniter, which, in turn, must first be ignited by pressing the button of the piezoelectric device.

The heater is equipped with a coaxial chimney - a pipe in a pipe, through which two gas streams move towards each other - air from the street to the burner, and gas combustion products out.

Wall-mounted gas convectors are mounted on inner surface the outer wall in the room planned for heating - over the previously made hole for the coaxial chimney.

Convectors for heating with gas are produced in two types of convection - natural and forced.

In units with forced convection, air is blown into the heat exchanger for heating by a fan, with natural convection flows are formed without consumer intervention.

The price of a gas convector depends on the class of its execution. The most expensive units are class C1 devices - with closed camera combustion and forced convection, heaters of class B11 (natural convection and connection to a conventional chimney) are much cheaper.

Conclusion

Classifying only some types of household heaters as convectors is very conditional - there are no heating devices whose operation would not entail the formation of convective flows. But when choosing a means of heating, one should take into account the size of the convection component in the efficiency of the unit.

Heating of small rooms is quite within the power of units with natural convection; in rooms of significant dimensions (industrial purposes) one cannot do without several such devices or heat guns - devices with forced convection.

The main essence of the article

1. To talk about the convector Oh, need to know, what's happened convection, and how it helps heating.
2. Although the principle of operation all convectors is based on the formation of convective flows, in everyday life only a few types of heating devices are called convector heaters.
3. Water convectors - reliable devices, improved over several decades of operation to heating units of high efficiency and safety.
4. Electrical convection heaters- modern equipment that is not tied to fuel reserves and does not require special knowledge from the consumer.
5. Convective-infrared heaters are combined heating units that use the phenomenon of convection in parallel with infrared radiation.
6. Gas convectors are heaters that are economical only in terms of the cost of the energy carrier. In fact, heat loss through coaxial chimney with products of gas combustion are significant.
7. When choosing heating equipment, you should consider the pros and cons various kinds convector heaters. At the same time, it must be remembered that convector heating units that are not equipped with forced air injection into the heat exchanger are inferior in efficiency to heating devices with fans, and the difference in price of these devices is fully justified.

The electric convector significantly outperforms its competitors - central heating radiators. Convectors do not "get confused" underfoot, as is often the case with mobile electric radiators. Aesthetic and easy to handle.

Why do we need electric convectors?

Electric convectors are needed to create a comfortable indoor climate during the cold season with poor central heating in apartments, and are also needed where there is no alternative way heat the premises - cottages, houses, stalls, pavilions. Depending on the ambient temperature, it is possible to regulate the temperature manually, or set the desired mode using the program controller.

How does an electric convector work?

The convector is an electric heater. Represents the metal case in which heating elements controlled by the thermostat are built in.

The heating element itself (heating element) consists of a high-resistance conductor placed in a ceramic sheath and hermetically sealed in a steel or aluminum case in the form of a radiator. This design greatly increases the area of ​​interaction with air. The temperature of the working surface of the heating element in the on state ranges from 60 to 100 C. The convector does not dry out the air and does not burn oxygen.

Scheme of the device of the electric convector

How does an electric convector work?

Convection(from lat. convectio- "transfer"). The principle of operation of the convector is simple. According to the laws of physics, cold air goes down and enters the lower grill of the convector. Moving, the air passes through the heating elements. During convection, the lower layers of air heat up, become lighter andrise to the upper layers. The upper layers cool down, become heavier and sink down, after which the process is repeated again and again. The constant movement of air allows you to create a comfortable temperature in the room.

Where is the electric convector installed?

Mostly installed under windows, but this is not important. Can be placed on the wall, where it is convenient.

Convectors are: wall and floor.

Wall convectors are usually quite high (height 40-45 centimeters). As for floor convectors, they are narrow and oblong (their height usually does not exceed 20 centimeters). It should be noted: despite the fact that wall convectors have a higher power of the heating element, it is floor convectors that heat the air in the room as quickly and evenly as possible. However, please note that the installation of a floor convector is more complicated than a wall convector.

Advantages of an electric heating convector

• Does not require supervision.
• Quick heating of the room, no drafts.
• The built-in electronic thermostat allows you to control the temperature in the room, significantly saving energy.
• The built-in thermostat prevents the heating elements from overheating and creating a fire hazard. This protection allows you to install the convector on surfaces made of various materials.
• Possibility of use in damp rooms.
• Everything modern convectors, unlike other heating appliances, are protected from splashes and moisture and therefore, they can be easily used even in rather damp rooms

• The protective metal case of the convector heats up to 45-65 0 C, at which it is impossible to get burned. The ergonomic design eliminates sharp corners, minimizing the risk of injury. Such characteristics allow the installation of a convector in children's rooms.

The convector does not burn oxygen, does not dry, but heats. The air stays fresh and odorless.

• The convector does not contain a fan for forced air supply, which ensures the complete absence of noise during operation.
• Ease of installation. Convectors can be mounted on almost any surface.

Selecting the power of the electric convector

• Ceiling height 3 meters.
• t 0 C comfort +19 0 C.

Wiring for an electric convector. We connect the convector!

The main rule for connecting a convector is to provide autonomous power for each individual panel. The cross section of the wire depending on the power consumption: up to one and a half kilowatts - a conductor cross section of 1.5 mm 2, more than one and a half kilowatts - a conductor cross section of 2.5 mm 2. The circuit is protected by an RCD with a setting of 30 mA. The conductor is laid directly from the switchboard and connected to a separate circuit breaker.
