The principle of operation of an electric convector

Electric convectors are a well-liked option for home heating since they offer convenient and effective warmth. These stylish appliances are a mainstay in many homes looking for dependable heating solutions because of their straightforward but efficient working principle. Making educated decisions about their heating needs can be facilitated by having a solid understanding of how electric convectors operate.

The heating element, which is usually composed of a conductive material like metal, is the central component of an electric convector. This element generates heat when electricity passes through it because of resistance. The room is then warmed by the dispersion of this heat into the surrounding air. Electric convectors generate heat exclusively using electric currents, as opposed to conventional radiators, which also use water circulation.

The capacity of electric convectors to heat a space quickly is one of their main advantages. Convectors produce warmth almost instantly due to their direct electrical heating mechanism, which enables them to provide comfort quickly when needed. This makes them especially helpful in rooms like living rooms, offices, and bedrooms that need to warm up quickly.

The accurate temperature control offered by electric convectors is another benefit. The majority of contemporary models have thermostats and movable settings, enabling users to precisely set the temperature they want. By avoiding overheating or needless energy use, this not only guarantees the highest level of comfort but also contributes to energy conservation.

Electric convectors work quietly and covertly, which makes them appropriate for a variety of living situations despite their efficacy. Convectors operate quietly and are simple to install on the floor or wall, saving valuable space in the home. This is in contrast to some heating systems that make loud noises or need complicated installations.

Electric convector heater – principle of operation and device

The models with convectors are unique among all electric heaters. They are highly sought after and are utilized to heat both residential and commercial spaces. Let’s attempt to comprehend the process of selecting a convector heater and identify the best model for supplementary home heating. Understanding how such a device works is essential to making the best choice.

Principle of operation

The natural circulation of air streams with varying temperatures is the foundation for the operation of electric convectors. Usually, the heating element is housed inside a small housing. Its surface has holes that allow air to circulate freely. Via the holes on the sides and bottom of the casing, cold air can enter. It leaves the heater through the apertures on the front side after being heated by the heating element’s energy.

Convectors operate differently from other thermal devices, such as well-known oil heaters, in that they rely on thermal radiation for their operation.

Kindly take note! Compared to other electric heaters, convectors heat a room significantly faster and more evenly because they use air flows to do the heating.

An alloy that can heat up quickly to a specific temperature is used as the heating element in electric convectors; this type of element is tubular in shape. As a result, depending on the starting temperature, the room gets warm within 30 to 60 minutes of plugging the device into the mains.

This kind of heater can operate at an extremely high efficiency of up to 90% thanks to the use of natural convection. The heat is released into the room immediately, which results in an increase in efficiency. As with the same oil models, there is no need to heat the radiator or coolant.

Dispelling Myths

Electric convectors have created a lot of myths during their time on the heating device market. One of them is that the gadget’s claimed TEN can burn through the oxygen in the space. This isn’t actually the case in reality. Special alloys are used to make the heating elements. Since they don’t get hotter than sixty degrees, burning out of oxygen is unlikely.

Airflow: Warm and Cold

Convectors with low operating temperatures also have the benefit of being able to be installed anywhere in the room. Because the device is fire-safe, placing it on a wooden wall is not a concern due to the heating element’s potential to catch fire.

We discuss the low operating temperature of the heating element and the high efficiency of convectors. Why is the air heated in this situation? Convectors have larger working surface area heating elements than other types of electric heaters. They effectively heat the room as a result, even at low temperatures. A single electric convector may be sufficient to heat an area up to thirty square meters, depending on its power.

Other usefulness

There are additional helpful "chips" in convectors. These are, to begin with, thermostats. Even the less expensive models have them installed. Maintaining a specific temperature is the thermostat’s primary function. Models with electronic thermostats provide the most accurate regulation. Generally, less accurate mechanical sensors are installed on simple, low-cost devices.

Models with a mechanical device are sufficient for home conditions because the temperature doesn’t need to be maintained within exacting parameters. Even an extremely cold room can be quickly warmed up by setting the thermostat to its highest power, after which it can be lowered.

Three different heating settings

In rooms where maintaining a specific temperature is essential, models featuring electronic thermostats are the better option. In this instance, the sensor will recognize the appropriate temperature mode on its own without the need for human input.

Another intriguing addition to the convector design is the voltage switch. Multiple heating elements can be found in high-power models, and you can adjust the number and power of heating elements at any given time using a switch. The heating elements’ separate switches have the same function. These models offer a significant benefit. The malfunctioning heating elements can keep working even if one of them fails. When one heating element burns out in a model that has a step switch, the heater will stop working.

Safe to operate

Because of the low operating temperature of the heating elements, electric convectors are guaranteed to be fire safe. Nevertheless, when installing the appliance, extra safety precautions need to be taken. For instance, there’s a chance the unit will topple over when mounted on the floor. The majority of models have extra sensors that, should the device topple over, cut off the power supply in order to reduce this risk.

Suitable for a child’s room

The sensor works on the principle that the contacts only stay closed when the convector is positioned vertically. The appliance works when the contacts are closed, energizing the heating element. The sensor opens the circuit and the heating element stops heating if the heater deviates from its vertical position in any way.

Remember that the presence of the required air convection is a prerequisite for the proper operation of convector-type heaters. This circulation is impeded by closed orifices, which means that the heater will stop working properly and may even break down entirely. The device’s openings should be kept open at all times to avoid such circumstances.

Advantages of convectors

Convectors are superior to other heating methods in a number of ways.

• Cost-effectiveness. The heating element has a low operating temperature, which minimizes energy consumption.
• Safety. Low operating temperature of heating elements makes the device fire-safe, and additional automation systems reduce any other risks arising from the operation of electrical appliances.
• Beautiful design. Convectors are compact, convenient, easy to fit into the interior and have a variety of ways of installation – wall or floor mounted.
• Easy installation. Unlike other electric heating devices, convectors do not require any special training from the person installing them. It is enough to place the device on the floor or fix it on the wall surface.
• Various modes of operation and the ability to precisely regulate temperature values.
• Absence of unpleasant odor and noise during operation.
• Providing constant air circulation in the room.
• Fast and uniform heating in minimum time.

Types of convectors

There are two types of models available on the market: liquid models and dry models. An immersed TEN is a characteristic of liquid units. Radiators are large because the heat is transferred to the liquid first from the heating element. They can even serve as a source of continuous heat. More often than not, dry electric convectors are utilized as an extra heating source in homes.

You can establish the ideal temperature regime in your home by selecting the correct kind and model of electric convector. The units are suitable for installation in any room, including the highly humid bathrooms and kitchens.

Conclusion

The primary benefits of these units stem from the convector heater’s operation principle, which is based on natural air circulation. They can be used to heat any kind of space, including ones where maintaining a steady temperature is required. They work well as a single or additional source of heat.

47. Design and principle of operation of a convector.

Convectors release the majority of their energy through convection. Its convective heat content is up to 80%; conduction and radiation account for the remaining heat transfer to the surroundings. This water heating system’s steel convector and electric convector are comparable. What kind of electric convector operates on what kind of principle, and how is it set up?

In understanding how an electric convector works, it"s like having a mini heating system right on your wall. When you switch it on, electricity flows through heating elements inside the convector, which then warms up. As the air around the convector gets warmer, it rises, creating a convection current. This warm air circulates around the room, gradually raising the overall temperature. The process is efficient because it doesn"t rely on moving parts or water pipes like traditional radiators, making it simple to install and operate. Plus, many modern convectors come with features like thermostats and timers, giving you control over your comfort and energy usage. So, whether it"s taking the chill out of a chilly room or maintaining a cozy temperature throughout your home, electric convectors offer a convenient and effective heating solution.

Device of the convector

The electric heating element and the casing are the two primary components of the electric convector. The most common type of finned heating element is the tubular electric heater. By increasing the surface area of the heater and lowering its surface temperature, plate-shaped ribs help to prolong the device’s lifespan. Certain manufacturers employ flexible heating wire in addition to ceramic and ceramic-metal elements as electric heaters.

The lower portion of the casing contains the heating element. The cover for passive convectors needs to be raised to a height of 200–400 mm in order to generate enough lifting force. Because the fan produces a significant density difference between the convector’s inlet and outlet, fan-assisted devices may be shorter in height. Windows for air intake and outflow are located on the top and bottom of the casing, respectively. Grilles cover the windows for reasons of ergonomics. In order to guarantee safety, convector designs typically include electrical isolation between the heating element and casing. As a result, the casing does not require earthing even with a steel convector.

Other elements may also be present in the convector. The convector can run at high power outputs thanks to the fan, which is four to five times more powerful than the passive device. A low temperature of the heater surface is attained as a result of the high-speed air stream that intensifies the heat exchange through the heating element.

A thermostat or programmer can be used to manually set the necessary heating power or to measure the ambient air temperature and set the convector power. Additionally, emergency sensors intended to guard against overheating and stop fires may be found in steel convectors. They frequently work in tandem with thermostats. Wheels are an option for floor convectors for convenient mobility. Convector installation is made easier with the brackets on the back of wall-mounted units.

Operating principle of convector

Convectors work on the following principle: cold air enters the casing through the lower window at floor level when the heating element is turned on. Heat exchange occurs as the air passes through the heating element and becomes heated. Warm air rises and escapes through the upper window, increasing the air density and heating the space. The same theory also applies to convectors that have a fan.

48. Device and principle of operation of the fan heater.

Contemporary heat fans are small and simple to install. Any interior can accommodate the heater with ease. To help designers better arrange furniture in the space, floor, wall, and tabletop heat fans are available from the manufacturers.

Not just during bitter frosts can a fan heater be useful. Apart from its primary purpose, the gadget can also function as a standard fan during the intense summer months.

When the heating element is in use, oxygen is burned and combustion elements contaminate the air. To address this serious drawback, heater manufacturers incorporate humidifiers into their products. By doing this, the room’s ideal microclimate is maintained.

You can control how much electricity costs when the heat fan is running thanks to modern devices.

49. Fireplace design and operation.

FIREPLACE: An improvement on the open hearth, the open room stove was invented. It can be fastened to or positioned within a capital wall’s recess. Κ. consists of an underfloor where the fuel is placed and a fuel box lined with cast iron plates or refractory bricks.

the principle of operation of any fireplace is based on energy conversion as a result of fuel combustion and transfer of heat into the room by convection. The combustion process is supported by oxygen, which enters the fireplace fuelbox together with the air. As a result, the sides " and the back wall of the firebox are heated by the flame energy and radiate a large amount of heat. At the same time, a significant part of the hot gases goes into the chimney, reducing the efficiency of the fireplace. To partially utilize this heat, the fireplace is designed to produce warm air. In this fireplace, cold streams are sucked in, pass into the cavities around the firebox and, heating up, go out into the room through special grates. Fireplace coal fireplace is possible in the presence of a powerful grate, so that the combustion zone from below air enters the zone. Coal is laid in a loose layer 5-6 cm thick on top of the burnt wood. The fireplace consists of a fuel box and a chimney without chimneys (turns). Inside the fireplace make a bent in the form of a knee gas threshold (pass, ledge, visor, tooth), which prevents the flight of sparks from the chimney, does not allow the difference in air currents, leading to the smoke of the fireplace, and the ingress of rain or snow water. The gas sill of the fireplace can be flat and trough-shaped. Often a tray is placed on it, and against it a cleaning, closed with a hermetic door. The width of the gas sill of the fireplace should be equal to the width of the chimney, and its projection should be on one straight line with the front wall (dotted line in the drawing) or even wider by 10-20 mm, which makes it possible to fully retain the falling soot. If the width of the threshold is narrower, it will not hold it back. In any design of gas fireplace sill, it should not narrow the chimney, thus preventing smoking. The draught of flue gases in the fireplace is weak, so over some fireplaces are arranged hoods or shafts in which the smoke is pre-collected and from the shaft it gradually goes out through the pipe outside. The pipe at the non-working fireplace should always be closed with a gate valve or a drum (rotary gate valve). It protects the fireplace from rapid cooling.

Household convector: principle of operation and installation

It is crucial to consider the heating system as a whole when furnishing a living area with all the conveniences, as the efficiency of the system’s operation is heavily reliant on the comfort of the occupants and the creation of a comfortable interior climate. Because this mechanism will enable dependable and even heating of the entire residential building, special attention should be paid to a modern and efficient device like a heating convector that runs on electricity.

Main differences between a traditional radiator and a convector

A standard heater is a device with three main parts: a thermostat for controlling the temperature, a heating element, and occasionally a fan. Such a device’s primary purpose is to heat the air in the space; however, the heat cannot be dispersed equally. For heating a small space in the room, this affordable and practical heater version will be useful.

To understand how the convector works, it should be noted that this equipment can be both floor and wall-mounted, and the principle of operation of the heating convector is in the natural convection of air, which is due to the name of this device.
Often such systems are equipped with special clamps, with the help of which the installation of heating convectors can be performed on the floor. The shape of convectors, as a rule, is rectangular. Answering the question of how the convector is organized, it should be noted that one of the key elements of its design is the heating part, through which the air passes and, heated, goes outside through the top of the device.

When comparing an oil radiator to a domestic convector, it’s crucial to remember that the radiator radiates heat while the convector creates a warm air flow inside that helps you heat the entire space efficiently and, most importantly, rapidly (see "What to choose convector or oil radiator").

Advantages of household convectors

Numerous factors contribute to the indisputable benefits of using convectors to heat homes and other residential spaces, making it possible to heat the desired area effectively and dependably.

The foundation of convector operation is the use of unique functional parts made of a unique alloy rather than the standard tubular electric heaters (TEN). One benefit of this device method is that there is no energy consumption for heating the device itself, meaning the room warms up quickly. Furthermore, these products have an extremely high coefficient of performance—more than 90%.

Convectors produce the least amount of noise while operating, and unlike conventional radiators, they do not dry out the air in the space or burn a lot of oxygen, disrupting the environment and fostering a pleasant microclimate.

High reliability and safety indicators are features of contemporary convector models, which are crucial given that the machinery depends on electricity to function. Because no part of an innovative mechanism comes into contact with the device’s body and no grounding is required for it to function, these mechanisms typically have the highest level of protection. Since these devices are dependable in their protection against moisture intrusion, you can use them in close proximity to bodies of water.

Convectors are also completely insensitive to periodic voltage fluctuations in the electrical network, so there’s no need to be concerned about them. They can operate at any voltage between 150 and 242 V, which is their natural voltage. The convector body itself heats up to no more than 55 ° thanks to the application of cutting-edge production technologies. As a result, these mechanisms can be installed in any room—including children’s rooms—without raising the possibility of a fire or overheating equipment.

When discussing the highest temperature that the heating element can reach while operating, it is important to note that contemporary convectors have this indication, which can range from 60 to 700 °. Naturally, a lower parameter is preferable. This is because burning oxygen is made easier by high temperatures, which goes against the fundamentals of convector operation.

Nevertheless, there is one major drawback to using household convectors: the equipment requires a lot of electricity to operate properly. At the same time, a number of factors (such as the room’s size, the presence of insulation, the kind of windows that are installed, and so forth) influence how much energy a standard mechanism uses.

To accurately determine the power at which the device will operate, the area of a given room must first be determined. It is reasonable to enlist the assistance of experts when performing computations. These experts can assist not only with equipment connections but are also prepared to offer a variety of convector photos and in-depth installation videos.

Where the convector should be installed

When choosing the best location for a heating convector installation, the following advice needs to be considered:

• the unit should be installed directly in the room to be heated;
• It is strictly forbidden to install the equipment in rooms with a lot of dust and those rooms with high fire hazard;
• thanks to the protection class of modern devices of this type, they can be placed in rooms with high humidity and near water, for example, in the bathroom, as the convector is not subject to damage in case of moisture;
• Do not install the convector under an electrical outlet;
• When installing the equipment, you should try to avoid placing it in a place with strong draughts, as temperature regulation in this case may be disturbed;
• special attention should be paid to the indents that must be observed when mounting the convector near any surfaces.

Installation process of the heating convector

The unit’s back panel features a unique fastening frame that needs to be taken off and fastened to the wall using four screws. Remember that there should be a minimum of 5 cm between the front of the unit and the closest object.

It is also crucial to remember that the indentation from the unit’s body, not its fixing frame, should be considered in any calculations. This frame has multiple unique holes drilled into its base for the installation of plastic brackets that can greatly ease the process of dust removal from the rear of the convector body.

Special norms of convectors operation

It is crucial to make sure that this heating equipment operates correctly when using it. This can be done by following these operating guidelines in addition to having the system installed correctly:

• the upper and lower grille of the convector should be cleaned from dust at least twice a year, and this can be done either with a brush or with an ordinary vacuum cleaner. The design of the appliance makes it easy to reach important functional parts and ensure that they are properly maintained;
• the unit"s body can be wiped with either a dry cloth or a cloth moistened in water, it is absolutely not necessary to use any special detergents.

Electric convectors are an easy-to-use yet efficient heating solution for buildings and homes. They function according to the convection principle, which deals with the transfer of heat via air movement. An electric heating element inside an electric convector warms the surrounding air, causing it to rise and generating a convection current. Warm air circulates continuously as cooler air is drawn in from below as the heated air rises.

The capacity of electric convectors to deliver rapid and reliable heat is one of their main advantages. In contrast to conventional radiators, which depend on the gradual heating of water, electric convectors have a high heat-up time, making temperature adjustments in a room possible almost immediately. This makes them especially helpful for rooms like living rooms, offices, and bedrooms that need heating on-demand.

Moreover, electric convectors give users exact control over temperature settings, enabling them to modify heat output to meet their needs for energy and personal preferences. With the thermostat and timer that many contemporary convectors have installed, users can set up heating schedules, maintain ideal comfort levels, and use less energy. This degree of control improves efficiency and reduces energy use in addition to improving comfort.

Electric convectors are not only convenient and efficient, but they are also reasonably simple to install and maintain. Convectors only need access to a power outlet and can be easily mounted on walls or placed on the floor, in contrast to central heating systems that call for intricate boiler setups and piping. They are a discrete heating solution that blends in seamlessly with any space thanks to their small size and elegant design.

To sum up, electric convectors provide a useful and effective heating option for both commercial and residential spaces. These devices are easy to install, offer precise temperature control, and produce fast, consistent heat by utilizing convection. Electric convectors are a flexible and affordable option for preserving a cozy interior atmosphere, whether they are utilized as a main heating source or as a backup option.
