Convector heaters. Pros and Cons

There are a number of heating options to take into consideration in order to maintain a warm and comfortable home. Convector heaters are a well-liked option for effectively heating areas. These stylish gadgets heat up cold air by drawing it into their heating element and then releasing it back into the space. However, they have benefits and drawbacks of their own, just like any heating solution.

The rapid and uniform heat distribution of convector heaters is one of their main benefits. In contrast to conventional radiators, which warm up slowly and often produce hot spots, convectors heat up a space quickly and evenly by moving air around. They are perfect for chilly mornings or evenings because you won’t have to wait long for your space to reach a comfortable temperature.

Convector heaters also have the advantage of being comparatively small and stylish. Convectors, as opposed to large, obtrusive radiators or space heaters, are frequently thin and discreetly placeable on the floor or wall. They are therefore a fantastic choice for people who like a more minimalist aesthetic or for rooms with limited space.

Convector heaters are also frequently complimented for their energy efficiency. They can be more effective than other heating techniques that depend on heating objects or surfaces because they heat the air and then circulate it throughout the space. Your energy bills may decrease as a result, particularly if you use them wisely in well-insulated areas.

It’s important to take into account convector heater disadvantages as well, though. Their dependence on convection currents, which implies they might not work as well in spaces with high ceilings or inadequate insulation, is one frequent source of worry. In these situations, the convector’s heat may dissipate quickly, making the room feel cold.

Convector heaters’ fan noise is another issue that some users find bothersome, particularly if they use them in bedrooms or other quiet areas where noise levels are important. It’s something to consider if you’re sensitive to noise or would prefer a completely silent heating solution, even though newer models might operate more quietly.

To sum up, convector heaters are a practical and effective way to heat your house, offering advantages like rapid heat distribution, compact design, and energy economy. They might not be appropriate for every space, especially ones with inadequate insulation or those where noise levels are an issue. You can decide whether a convector heater is the best option for your heating needs by being aware of the benefits and drawbacks.

Pros and cons of the equipment

Among convectors’ benefits are:

• Noiselessness. The absence of a fan ensures quiet operation of the equipment;
• A wide range of installation options: floor, wall, baseboard;
• Compactness and aesthetics. The equipment will not spoil the appearance of the room;
• Do not burn oxygen;
• Durability. Manufacturers give a warranty service life of up to 10 years;
• Safety of operation. The body does not heat up above 50-60 degrees. Most models are equipped with temperature sensors, eliminating overheating of the equipment;
• Easy to operate, temperature adjustable;
• If there is a thermostat, you can maintain a certain temperature in the room;
• Large power range – from 0.25 to 2.5 kW;
• There are models with additional options: remote maintenance, moisture protection, timer, etc.;
• Low price of equipment.

Convector heaters have drawbacks in addition to their many benefits, as attested to by user reviews:

• The absence of a fan causes slow heating of the room;
• Cheap devices can emit an unpleasant odor when the body is strongly heated;
• Air circulation leads to the movement of dust in the air, which negatively affects allergy sufferers, children;
• The temperature difference between the ceiling and the floor, sometimes significant;
• The device dehumidifies the air;
• The need for regular maintenance, cleaning the internal device from dust. In the event of a breakdown of the heating coil, a complex and expensive repair is required;
• Over time, the efficiency of convectors of the electric type decreases, which is due to the wear of the heating coil.

Some drawbacks, though, are excludable. For instance, certain Electrolux AirGate models with an X-shaped profile on the heating element are available for purchase. They hardly ever get dust accumulation on them. As a result, the Electrolux heater operates more efficiently and doesn’t require cleaning.

One should also consider the high power consumption of electric convectors as a drawback. However, the implementation of energy-efficient models mitigated even these operational drawbacks.

There are two types of these devices:

Devices with microprocessor control are available for purchase, enabling you to alter the operating mode. A convector, for instance, will operate more vigorously when someone is home; in their absence, the device either operates at a low power or not at all.

Additionally, new liquid convectors with reduced energy consumption were developed, allowing for operational savings. Though there is an extra container inside the device that holds coolant, the device operates on a similar principle to conventional models. You can use less electricity because the element serves as a mediator between the air and the heating element. These gadgets are more expensive, though.

How to choose for home and dacha

There are many different types of convectors available on the market today. When their features diverge significantly, it can be difficult for the uninitiated user to decide which electric heating convectors to use. You can make the best decision by following a few easy suggestions.

Power of the device

The amount of heat in your house determines how powerful the convector should be. In addition, selecting the best device is not too difficult. A room that is 10–12 m2 in size can be adequately heated with about 1 kW of power, assuming that the room does not have central heating. This convector power will be sufficient for a room twice as big if it is (and functions). In other words, with a 20–24 m2 area.

But, you should also consider the room’s purpose when selecting electric heating convectors for this or that room. For instance, a more potent appliance might be needed in a living room and bedroom of equal size than in a kitchen of comparable size.

Installation

There are two varieties of 220v convector heaters: portable and stationary. As long as the cord is reachable, you can move the device anywhere in the first scenario. However, wall-mounted stationary electric convectors are the best option.

Controls

Even the most basic electric ceramic heating convectors have a unique power regulator that allows you to constantly change the room’s temperature.

Convectors can also be programmed, meaning that certain models can be set to automatically turn on and off at specific times to raise or lower the temperature to a predetermined level.

These convectors are naturally a little more costly, but they will enable you to set the most comfortable temperature. In this instance, setting the program just once is sufficient to regulate the device’s heating instead of doing so on a regular basis.

Modernization of the best electric heating convectors available today is possible. Specifically, you can purchase an extra unit and use a specialized remote control to operate the convector from a distance. If the convector is placed, say, in a child’s room, this is very practical. The temperature can be changed without going inside the space.

Safety

Convectors are now available in waterproof models, which are ideal for high-humidity rooms. Installing a convector like this in the bathroom allows you to install it without worrying about unanticipated events.

Furthermore, nearly every convector model has a dedicated overheating sensor. That is, the gadget will automatically shut off if it reaches its maximum temperature. Additionally, turning on can be done manually or automatically, depending on the model.

Dimensions

Convectors come in a wide variety on the market. As seen in the picture, they can have a variety of shapes (square, rectangular), thicknesses, and even colors. You can select the gadget that you require the most.

Tips

Any electrical appliance used in a home must be used strictly in accordance with safety regulations. This also applies to electric convectors. As reviews and suggestions demonstrate, there are a few warnings that must be considered:

• The appliance must not be covered under any circumstances. Some housewives can use an electric convector as a clothes dryer. But it is strictly forbidden to do this.
• Do not install the convector in close proximity to an electrical outlet. The distance should be at least 0.8 m.
• In rooms with high humidity, you can only use convectors with appropriate protection against moisture. All of them are labeled with the mark "IP 24".

Make an effort to purchase only high-quality appliances from reputable producers. Too-cheap devices might end up being of poor quality, and you’ll quickly regret buying them.

Temperature difference

You won’t find this drawback to be the most significant if you have poor perception of air temperature. However, the convector heater design will not appeal to you if you feel that the temperature is changing literally by a degree. This is because there will be a noticeable temperature difference between the upper and lower portions of the room, which is a glaring drawback. The most basic sense of the difference is that people’s feet become cold.

We suggest that you purchase convector heaters because they offer more even heating and have outlet holes on the front wall rather than the upper end.

Low heating speed

A fan-equipped electric convector heats the space considerably quicker.

A noticeable drawback, but one that will only be apparent during startup and temperature adjustments on the regulators, is that convector heaters have a sluggish rate of heating. However, convector heaters with integrated forced convection fans can be purchased to get around this drawback. Since the fans are interchangeable, there won’t be any discomfort at night.

Low efficiency at high ceilings

Not the biggest drawback, as most homes have ceiling heights of three meters, or less frequently, three meters. Convectors become less effective at higher ceilings because it is harder to create convection and the temperature differential between the top and bottom is too great. Higher power infrared devices work best in these kinds of rooms. Purchasing convectors would be a waste of money.

Convectors are dusty

While models with built-in filters are less dusty, they still require routine cleaning.

You should expect dust to circulate throughout the rooms if you install convector heaters in your house. Although it is not necessary for healthy individuals, it is preferable to remove dust. Small children and allergy sufferers should avoid the dusty environment. If you choose to use convector heaters for heating, be sure to give the equipment regular damp cleaning and dust removal.

Additionally, keep an eye out for models that have integrated dust filters.

Other disadvantages

Finally, let’s talk about a few more minor drawbacks:

• When convector heaters work, weak drafts are formed – they are noticed by some sensitive people;
• Convectors can crackle – this is the effect of thermal expansion of materials, but it is not noticeable in all appliances;
• There may be an unpleasant odor – most often it is noticeable when first switched on. If the odor is constantly heard, the problem lies in the cheapness of materials from which the equipment is assembled – do not save on heating.

Rational solution gas convector

Gas convectors operate with either liquefied (cylinder) or natural (mains) gas. A power source is not necessary for them, unless the model has a fan to enhance air circulation. However, these gadgets function silently even in the absence of electricity; the fan merely stops rotating. Although they can have an auxiliary function, the units are typically used as the primary heating devices.

Gas convectors are typically used in small-to medium-sized private homes or outbuildings. This is the best option for a vacation home.

Advantages and disadvantages of the equipment

It is worthwhile to emphasize the following benefits of gas convector heaters in addition to "electrical independence":

• These devices are not afraid of frost and can be safely left in unheated houses;

The products are safe because, in an emergency, the gas supply is automatically cut off.

The device’s simplicity is a major benefit, as it contributes to the appliances’ high efficiency rate and dependability.

Accessibility in terms of cost and technology

Financial benefits of installation and purchase

Device for quickly heating the space

The apparatus has certain drawbacks:

• despite the small size, gas convectors are usually difficult to successfully fit into the interior;
• it is necessary to "chisel" the wall for coaxial gas outlet.

The fact that the gas unit cannot be easily "moved" to a different location is a major drawback.

Gas convector design

The parts of the gas heater are as follows:

1. Metal housing. It is covered with heat-resistant paint. The bottom and top of the design is open for air circulation.
2. Ribbed heat exchanger. Heats the air. The larger it is, the faster the room temperature rises.
3. Burner. This is where the gas is burned.
4. Combination valve. Responsible for regulating the gas flow into the burner.
5. Chimney. Diverts smoke away from the device. Not all manufacturers include a chimney in the delivery set – it is worth paying attention to this when choosing the equipment.
6. Thermostat. Element for controlling the operation of the combination valve.
7. Automation. Shut off the gas supply in abnormal situations.

Additionally, more expensive models of gas convectors can come with a fan and remote control.

It is only appropriate to discuss the economy of gas convectors when discussing the installation of one or two units within the home. The way the equipment is installed in each room is a complete mess.

Recommendations on the choice of devices

It is imperative that the product is adjusted to the pressure within your gas system. The well-known formula is used to determine the necessary power for the gas convector: one kW of heat is needed for every ten square meters of space. It is not unnecessary to add 1 kW to the obtained value in the case of old windows or subpar insulation.

Devices can be floor or wall mounted, depending on how they are attached. Since the first ones are more portable, lightweight, and powerful enough, choosing them is typically advised.

The material used to make a gas heater’s heat exchanger is a crucial consideration when making your selection. It might be:

A cast-iron heat exchanger can function for fifty years, heats up uniformly, and has a high enough efficiency. However, because cast iron is a brittle material, it may burst in specific circumstances (such as a significant temperature difference). A design like that also weighs a lot.

Heat exchangers made of aluminum have a low heat resistance despite having good thermal conductivity. The devices that are fitted with them are expensive.

The best option is a steel heat exchanger. In many aspects, it is unquestionably less than the "competitors." However, it is affordable, lightweight, and strong.

The inclusion of a fan in a gas convector’s design is a nice bonus. Although the risk of burning the heat exchanger is decreased and the room takes less time to heat, the equipment cost goes up.

Because of the fan’s increased air flow to and from the heat exchanger, the heater produces a significant amount more heat.

How to choose a heater

You must determine the power consumption, heating area, and your own needs and capabilities before selecting convectors. The following are the primary standards used in the selection of the devices:

1. If you want to save money, you can buy a convector with a mechanical temperature regulator, it has fewer options than the automatic, but the cost is much lower, there is no need to deal with settings and instructions;
2. Each series of any manufacture has its own peculiarities, be careful not to overpay, but at the same time to meet your needs;
3. Installation is very important. The best options for the bathroom are wall-mounted hinged models, for kitchens or large areas – stationary models that are placed directly on the floor. If you plan to make a warm floor, you can install skirting or "hidden radiators;
   Photo – Convector in the bathtub
4. Often inexpensive models have fewer settings, they have lower power, carefully read the documentation, make sure that the sale is from an official dealer;
5. Calculate the power correctly. For example, a 6 kW heater is quite enough for 40-50 square meters. For example, a 10-square-foot heater can be used for 70 square meters, while a 10-square-foot heater can be used for 70 square meters or more. But this indicator varies from manufacturer to manufacturer.

The principle of convector heater operation is to maintain a stable temperature

The electric current is temporarily turned off if the temperature of the cold air entering the heater is high enough. An electronic watch is kept on this process. The body is equipped with a temperature sensor, which transmits data to an automated device that controls the electric current supply. The air in the room cannot overheat thanks to this system. A digital indicator that displays the room’s temperature is included with some heater types.

How convector heater works in fall and winter?

The convector heater’s maximum power is 2 kW. In a room no larger than twenty square meters, it is sufficient to keep the temperature comfortable as long as the outside temperature doesn’t fall below zero. During the fall temperature dip, such a heater works well.

The 2 kW power is insufficient to heat the room during winter frosts. Convector heaters can be used as an extra source of heat during frosts, but they won’t take the place of central heating.

For this kind of heater, the volume of circulating air is just as important as capacity. It’s important to keep in mind how the convector heater operates: for the room to circulate air, air must pass through it. It is widely acknowledged that one kW of heater capacity is needed for every ten square meters. One heater is insufficient in a room larger than twenty square meters; two heaters should be present.

Is it feasible to install doors and windows that close tightly to improve heating efficiency? In actuality, heating the air will become more efficient, but air composition hygienic standards may be broken. The issue is that ventilation is necessary because a certain amount of air cannot remain in the living area continuously. 20 square meters of floor space necessitates an hourly air exchange of 20 cubic meters. People won’t experience a sudden drop in temperature in the room if the air entering it goes through the convector.

Construction and design of convector heaters

Convector heaters are designed with flat panels. Their thickness is small and their side surface is large. These gadgets are split structurally into floor-mounted and wall-mounted sections.

The wall-mounted model conserves room. The heater blends in more seamlessly with the interior thanks to the pleasant light coloring of the casing. One benefit of the floor plan is that the heating panel is mobile, allowing for easy room movement.

water convectors for in-floor heating

Apartments, homes, car dealerships, entertainment centers, hospitals, shops, and other establishments all have built-in floor convectors. An in-floor convector will be the best option for heating rooms with a lot of glass, such as swimming pools, greenhouses, airport buildings, and the terraces of country homes and cottages.

An in-floor water convector’s cost is determined by its manufacturer, size, type, design elements, and technical specifications.

Design

A heat exchanger housed in a unique casing is an in-floor convector for water heating. Connected to the water heating system, the heat exchanger is a copper-aluminum heating element with exceptional resistance to corrosion.

In the event of a leak, the built-in convector’s casing, which is typically composed of thick sheets of stainless or galvanized steel, reliably protects the floor covering.

The heat exchanger casing is inserted into a pre-made floor niche or straight into the cement screed. It is covered with an aesthetically pleasing grille that conceals and shields the interior of the recessed in-floor heating radiators.

Stated differently, the visible portion of the built-in convector is a decorative grate that is situated at the same level as the floor covering. It can be constructed from a variety of materials with a broad range of textures, shapes, and colors, and it can also be painted the client’s preferred color.

Types of in-floor convectors

Two types of in-floor convectors are distinguished:

• convectors with natural convection;
• convectors with forced convection, with built-in tangential fan, which contributes to a more intensive heat exchange.

Typically, fan convectors serve as a room’s primary heating source.

Natural convection convectors are supplemental heaters. They are utilized with underfloor or radiator heating systems and are intended to insulate large windows and doorways from cold air.

Any kind of in-floor convector can be linked to the regulation system.

Advantages

• space saving, due to the fact that the radiators are located in the floor;
• attractive appearance, which does not disturb the overall aesthetics of the interior and can fit into the design of any direction;
• a wide variety of sizes, allowing the heating device to be matched to the parameters of the room, providing the required heat output;
• reliability, efficiency and durability of the devices, provided by the use of corrosion-resistant materials of high quality.

Varieties of heaters

There are many various space heating devices available on the market today. Popular in addition to convector are:

• Oil. A metal casing with oil inside. The tubular electric heater heats the oil, the heat from it is transferred to the body and then to the air in the room. The devices are characterized by high durability, have a long service life, are compact and quiet, are inexpensive, but can be installed only on the floor. To heat a large room with their help, it will take a long time (more than half an hour). Some models are equipped with a special design that allows drying laundry.
• Infrared. Their design also consists of a metal enameled casing and a heating element. The principle of operation is based on the conversion of electrical energy into heat energy. Infrared rays heat all objects in the room. Thanks to this, the amount of oxygen is not reduced and the air is not dried out. The devices quickly heat large rooms, can be mounted on the ceiling, walls or installed on the floor. Built-in thermoregulators allow you to set the optimal temperature mode and save energy. The main disadvantages are the negative impact on health during prolonged operation, high cost and impossibility of use in rooms with ceilings below 2.5 meters.

The degree of safety involved in using any heating apparatus is a crucial component. Appliances that run on oil, infrared, or convector have dependable fire and breakdown protection. The only way to guarantee a high degree of safety is if clear If you adhere to the heaters’ operating guidelines:

1. When connecting, make sure that the voltage in the network corresponds to that specified in the instructions.
2. The switched on device must not be installed near sources of fire and easily ignitable objects, touch or place things and foreign objects on it.
3. Damaged housing is prohibited to repair independently. Should be handled by specialists.

Heaters that run on oil, infrared, or convection can only be used indoors. It is not permitted to operate outside.

Advantages of convectors

1. Easy installation, operation and removal. There are no special installation requirements, in most cases this is limited to simply mounting on the wall and plugging into a socket (unless piping is required). There will be no problems with management, many instructions explain step by step the installation, principles of operation and rules;
2. Durability. Each modern electric convector such firms as Electrolux, Atlantic, Dantex, Aeroheat, Siemens, Sensei, Glamox, Stiebel, Etalon, Dimplex and others work from 10 to 25 years;
3. Accessibility. This is the key difference between electric heating appliances and solid fuel or gas heating appliances. At a relatively low cost, they can heat the same room as similar expensive solid fuel boilers;
4. The most important advantage is that they can be installed in a room with children and pets. Open fan heaters tend to dry the air, destroy oxygen, which often causes dryness in the nasopharynx, it is difficult to breathe and sleep, thanks to oil radiators this problem is solved. Also the working surface is most often cold, for example with ceramic heaters;
5. Conventional radiators can not be set to maintain the specified temperature, and almost all modern convectors have a built-in thermostat that allows you to control the temperature to a degree;
6. Electric household convectors for a house, apartment or cottage are very economical, many manufacturers have characteristics of the device allow them to be installed for hourly heating, to save heating of certain parts of the apartment, etc.д.
7. Complete silence of operation is also an undoubted advantage among other heating devices. They can work in complete silence, which is great for heating a child"s room, will not cause discomfort in sleep and adults. The only part that makes sounds is the automatic switch. Convector thermostat periodically switches modes, clicks can be heard;
8. The highest efficiency index among all heating devices – from 95% to 98%.
9. Convector does not spend time on "acceleration", heating of working parts and draught, so it starts to heat immediately, which is very noticeable, especially in winter.

Price overview

The primary factors influencing the price of electric convectors are their technical attributes, power output, and heating capacity. It is important to note that local producers in Russia, Belarus, and Ukraine frequently offer their convectors at a lower price than those made in France, Germany, or Norway. For instance, compared to Finnish Evub or Ensto, Russian Atlantic is significantly less expensive.

Which is better oil or convector heater

We have previously discussed the working principle, benefits, and drawbacks of convectors; let’s now become acquainted with the primary technical features of the oil radiator. These gadgets are typically used to heat the air in homes, dachas, or apartments in cities. The device must be plugged in to power and have the thermostat adjusted to the desired temperature before it can function.

Cooler for oil

A radiator-shaped metal housing makes up this type of heater. The middle of the container is filled with mineral oil, which absorbs heat from the heating element. A rheostat built into the device enables you to switch it off when a predetermined temperature is reached.

The heater is designed to prevent unintentional overturning. The heating element is disconnected in this instance.

The following are some benefits of oil radiators:

• Noiselessness;
• Low cost;
• Ability to move the device around the apartment to warm up the desired room.

The power of the device is a factor to consider when selecting a radiator heater in the store. In this instance, a room with a 10 m2 usable area is intended to use 1 kW of electricity.

One to 2.5 kW is the range of power consumption. A timer on some models lets you set the ideal temperature for the room.

Different types of oil heaters

Let’s now become acquainted with the features that these two heaters have in common:

• The first important nuance of the choice is economy. Here it is necessary to give advantage to convectors, because they consume 25% less electricity;
• The second parameter – heating time. When switching on the convector heats the air immediately, its efficiency can exceed 95%. In the second device first heats the heating element, then the oil, the metal body and finally the air in the room;
• The next important characteristic is the ease of operation (movement). Convectors have small overall dimensions, they can not only be placed on the floor, but also hung on the wall. Oil radiators are massive, their weight can reach up to 25 kilograms, they are unsuitable for installation on the wall. The unit has wheels for more comfortable movement, and if you need to bring the unit to the 9th floor in a house with a non-working elevator;
• Operation period. According to the technical specifications, the convector can last at least 5 years, but in practice it is more than that. Quality oil radiators also have a huge motor resource, but cheap Chinese models can give cracks in the metal, which leads to oil leaking from the body;
• And the last characteristic is the price of the device. Here the undoubted leader will be oil heaters.

The ideal choice over an oil radiator is a convector.In conclusion, convectors should be preferred when comparing these two heaters.

Advantages over other types

Other popular types of heaters are oil, infrared, and heat fans, in addition to convectors.

Oil

A basic mechanism underpins the oil heater’s operation. Technical oil fills a metal hermetic case, submerging heating components in the fluid. The oil emits a great deal of heat when heated, and the space warms up fairly quickly. Oil radiators are beneficial because they heat the air for a while even after being disconnected from the network because they are reasonably priced, use little energy, and hold heat for a long period. Since the majority of these heaters are floor-format models, they are sufficiently small and lightweight to be utilized in nearly any space.

The one exception is that oil radiators shouldn’t be installed in kid’s rooms because they can burn small hands because of their extremely high operating temperature. The high temperature can also cause adjacent surfaces and objects to become darker. The air is heated by the device in an extremely uneven manner; it is too cold in the distance and too hot when one is close to it.

Oil heaters are slightly less expensive to purchase and run than convector heaters, but because convector heaters heat the air more rapidly and evenly, they are safer, greener, and more convenient.

Infrared

A room’s designated area can be heated with an infrared heater. The infrared lamp’s heating capacity and the reflective surface that focuses the heat streams on the intended area serve as the device’s foundation.

The ideal settings for this kind of heater are offices and other spaces where people spend a lot of time together. The air outside the workspace will still be very cold, even though an infrared lamp will quickly heat it and the worker.

In addition to using less energy, being durable, and not consuming oxygen, infrared lamps are a more effective option when it comes to heating a specific area quickly and effectively. They have no harmful effects on the human body and are completely safe. Apart from serving as work spaces, they are frequently employed for heating balconies or pergolas; however, they are highly inconvenient in residential buildings and apartments.

Fan heaters

The least expensive type of heating device is a heat fan. Nevertheless, it uses a lot of electricity quickly and has a relatively high energy consumption level. The entire device will need to be replaced if the heating coil breaks because it can no longer be repaired. The heat fan burns oxygen in the space while it is operating, producing a loud, monotonous noise. Some copies may also release an unpleasant burning smell.

It’s important to know the benefits and drawbacks of convector heaters when it comes to insulation and heating your home. Convector heaters heat a space quickly and effectively, dispersing heat equally over the space. They’re a practical choice for additional heating because they’re frequently portable and reasonably simple to install. But, because they depend on convection currents, they might not be the best option for rooms with high ceilings or larger spaces. Furthermore, even though they produce heat right away, they might not hold heat as well as other heating techniques. Convector heaters continue to be a popular option for many homeowners despite these disadvantages because of their affordability and adaptability.

Overview of quality characteristics of electric convectors

It’s important to become familiar with the key features of the models available on the market before selecting a convector heater. Power outputs range from 250 to 3000 watts. Models with the highest wattage can be used as the primary heating source, while those with the lowest wattage are used as an additional heating source. The range of the heated area is 1 to 35 square meters. It can be quite challenging to heat a room that is too large.

Only after learning what kind of heating element is installed inside can you make a decision. It can be a heating element in addition to a monolithic or ribbon element. It is advised by experts to lean towards selecting a monolithic heating element. Selecting a heating convector? Reviews and the fundamentals of operation should all be researched beforehand.

But it’s also critical to consider the installation type, which can be either floor- or wall-mounted. When choosing an installation method for equipment that will only be used in a single room, the wall-mounted option is recommended.

This will preserve the room’s open area.

Control, specifically touch, mechanical, or electronic control, can have an impact on the price. Although the first kind is more expensive than the others, it is quite rare. It’s advisable to choose the electronic thermostat over the mechanical one if you’re still undecided. The equipment operates on the principle of moving air masses. The quicker the appliance is lowered, the quicker the room will warm up. The maximum value of this indicator is 65 centimeters.

Convection phenomenon

A temperature schedule that fits the room’s intended use is one requirement for a comfortable stay. When we discuss the winter season, we imply that the air inside the house must be warmed to a specific temperature, which is accomplished with the use of domestic heaters.

The ones that don’t harm people or put people in danger of fire or explosion are the ones that are currently in use for heating the air in living rooms. For obvious reasons, it is inappropriate, for instance, to heat a living room with an open fire; however, the same fire in a fireplace or stove will heat the walls of the firebox, which will heat the air in the room. This kind of housing heating is commonly used.

Heat exchange, or the transfer of heat from air to an object that is hotter than it, is what raises the temperature in a room. attained in two methods:

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

Convector heating is conditioned in both situations by the so-called convective flows. When air comes into contact with something hot, it gets heated and expands in volume. Because heated air is less dense than cold air, it rushes upward and gets replaced.

Convection is the term for this continuous process that takes place at a constant high heat exchanger temperature.

What does heating convection mean? Cool air (cooling hot air) travels downward and heated air (from the heat exchanger radiator or infrared-heated objects) moves upward. Since liquids behave similarly when they come into contact with a heat exchanger, convection circulation is another name for the circulation that occurs during heating.

How to choose for the dacha

The following factors should be taken into consideration when selecting the heater that will be used in the dacha:

• Safety of using the appliance;
• Durability performance;
• Cost;
• Economical use of electricity or other heat carriers.

Within the space, a convector heater

The fact that the device will be used must be considered when deciding between floor-mounted and wall-mounted versions. Many varieties of electric convectors are mounted to the wall; in the event that the heater needs to be moved, extra hardware will need to be bought (wheels, protection against heating during accidental tipping).

Floor convectors are long and narrow with a maximum height of 20 centimeters. Models that are wall mounted have a height of 50 centimeters. Since heated air moves from the top to the bottom, experts say that devices with the highest efficiency are those that are as close to the floor as possible. In this sense, it is preferable to install wall-mounted devices as close to the floor as possible or to avoid purchasing wall-mounted equipment altogether.

It is vital to pay close attention to the housing’s overall dimensions, design, and material and manufacturing quality when purchasing such devices. Here, the housing height is important to consider because a higher housing height will result in a higher air flow rate or greater convector qualities from the heater.

Because plinth convectors are large, with a height of up to 20 centimeters and a length of up to 2.5 meters, they effectively warm the air. A taller heating device (up to 60 centimeters) with faster airflow will be more compact.

Installing the convector nearer the floor is preferable.Note: It’s a good idea to read user reviews of this or that model before making a convector purchase. Individuals who have utilized these heating devices typically list both their benefits and drawbacks.

Characteristics of convector heaters

Rectangles are the primary shape in which these devices are manufactured.

Convector heaters are based on a design solution, which means that nearly all models are the same. The device’s height is the only variable that can change.

When selecting a heater, keep in mind that the lower the device, the faster air will pass through it, causing the room to warm up considerably quicker.

The following categories of heaters use convection:

• Electric;
• gas;
• convector-infrared;
• water;
• film.

Electric vehicles are reasonably priced. They are simple to use and install. However, it should be kept in mind that using electricity for heating is far more expensive than any other method (such as using coal, gas, wood, etc.). No exception applies to convector devices. Should you decide against purchasing such a device, be ready for a multiple-exposure increase in the cost of electricity. These models are not ideal for large areas, and the power and heating speed may eventually drop. An appliance that has automatic overheating protection is regarded as fire-safe.

Water serves as the heat carrier in water models. The apparatus may have an in-floor design or resemble a traditional radiator. The gadget is mounted on the wall and linked to the central heating system in the first instance. It uses not a lot of electricity. It is lightweight and suitable for mounting on plasterboard walls.

Gas models are particularly cost-effective since they run on the most fuel that is available. The apparatus has two mounting options: wall or floor. Link it to a primary gas cylinder or supply

The absence of a chimney, high cost, need for special care during operation, and connection are the drawbacks of gas heaters.

Cinema models are a new concept. One such gadget is a two-layer film that acts as an electrical insulator and contains heating components. It is simple to hang on the wall, doesn’t detract from the room’s aesthetic, and can be rolled up and stored away after use.

Two technologies are combined in vector-infrared models. Despite its effectiveness, this device is too expensive.

The heart of the convector is the heating element

The following characteristics of the heating element (TEN) design determine the convector heater’s performance:

1. durability;
2. efficiency;
3. energy consumption level;
4. cost.

An open coil, a simple heating element, is installed inside devices that are inexpensive. The convector models listed above are made by both domestic and European producers. Open spiral devices have a low protection class IP and should not be used to heat rooms with high humidity levels. The open coil operates at a high temperature of 500 degrees Celsius; the burning dust will produce an offensive stench, scorch oxygen, and serve as a fire focus when large flammable objects fall to the surface.

Convector electric heaters with closed-type heaters will operate safer and more dependably. The filament is inserted into a steel tube to form the heating elements. The closed heating element operates at a low temperature of no more than +100 degrees Celsius. The steel tube has an aluminum heat sink installed to improve heat transfer. Aluminum has a high heat conductivity, so the radiator heats the circulating air quickly.

Steel heating elements with aluminum radiators have a few drawbacks. Over time, the density of contact between the steel tube’s surface and the radiator breaks down due to variations in the coefficients of thermal expansion of different materials. The device’s efficiency declines as a consequence. The heating element may overheat locally, which is the worst case scenario. will cause the heating element to burn out, creating a fire hazard.

The most expensive and contemporary electric convector models come with a monoblock heater. Radiator and heating element are single-piece assemblies. TENS are dependable in their operation; their product has a 20-year service life. The heating filament of solid-cast heating elements is immersed in a unique filling made of small quartz crystals and other materials. The housing is constructed from aluminum alloys. For instance, molded siluminous TENS is a feature of Noirot brand convector heaters in France.

The models that combine the best heating performance and lowest energy consumption are those that work well together, like convective infrared heaters. Apart from the heating component, an infrared panel is also fitted. The convective infrared heater’s perforated front panel allows IR radiation to flow freely, illuminating the room and setting it apart from a conventional convector.

Working principle

There are apertures on the top and bottom of the casing of a convector heater. Via the lower apertures, cold air enters the equipment, is heated by heating elements within the housing, and then rises to the top of the space. Without the use of fans, circulation occurs naturally. Despite the fact that certain models use forced air circulation.

Thermostats on contemporary equipment let you adjust the necessary heating temperature.

It is advised to place the convector heater above the windows for uniform heating. The heated interior draws in cold air through the equipment. A sort of heat curtain is produced in this manner. As a result, installing modestly powerful devices over each window is preferable to installing a powerful device over a single opening.

Working principle of electric convector heaters

The basic physical principle underlying the convector radiator’s operation is that hot air rises and cold air descends. The air moves normally through space.

The appliance’s lower half houses the heating element. Flat fins on the heat exchanger increase heating efficiency. The heater’s entire structure is covered in a casing with holes for both hot and cold air. Compared to other kinds of radiators, the case does not get as hot.

Various convector types:

• gas;
• electric;
• water.

Their primary distinctions are in the kind of energy used and, consequently, in the characteristics of the construction.

An electric heater and a gas heater operate in the same manner. It has a gas burner inside the heat exchanger in place of a heating element. Heat energy is released when gas is burned, and this energy is then transferred to the heat exchanger to heat the cold air that is coming in.

However, there is a big drawback to such a convector: the fuel’s combustion products have to be released into the chimney. Consequently, it is not possible to relocate the gas radiator from one room to another. Considering that they have a 2–6 kW productive capacity, these can serve as the primary heat source.

Water, oil, or antifreeze-based liquid coolants are the source of energy in water heaters. A heater is a liquid-moving metal pipe with welded ribs. One example of a convector is a basic central heating radiator. Water heaters use convection only; no thermal radiation is used, so the body is essentially not heated.

These radiators are as follows:

• steel (the entire construction of the appliance is made of steel);
• bimetallic (tube – of copper, fins – of aluminum).

The least expensive option is steel. Although two-metal convectors are more costly, they are more efficient, long-lasting, and resistant to corrosion.

Electric heaters are among the most widely used battery types. They are convenient to use and simple to install. You only need to place the plug into the socket in order to connect the appliance. However, because they only have a power of less than 2 kW, these heating elements can only be used to provide extra heating for the space.

The electric radiator’s heating components are:

• open coil;
• closed coil (TEN);
• monoblock.

The least expensive converters are those with an open coil, but they have drawbacks:

• heating up to 150 degrees;
• burns oxygen from the air;
• unpleasant odor when dust gets on the coil;
• should not be used in places with high humidity.

Characteristics of TEN-based designs

• they can be heated up to 100 degrees Celsius;
• do not burn oxygen;
• do not emit unpleasant odors, t. к. they do not get dust on them;
• TENS may overheat – even burn out – due to the different thermal expansion of aluminum and steel parts of the device.

Monoblock heating elements are a feature of the best electric convector heaters. These devices are much more expensive, but they are also very dependable and have a long service life.

Minuses of convector heaters

Though they are far less common than the pros, these are still fairly important:

• high power consumption;
• decreasing efficiency over time;
• the presence of noise during heating.

Due to their high performance, the majority of the devices in this category use a sizable amount of electricity from the network. The majority of models, even the most basic ones, seldom use less than 1.5–2 kWh. Electricity bills from these operating parameters are impressive. They frequently have a big impact on the pocket, particularly during the winter.

The tubular electric heating element loses efficiency with time. The heating coil and the metal casing get farther apart as a result of continuous exposure to temperature variations (Fig. 5), which releases heat into the surrounding atmosphere directly.

Figure 5

When heating up or cooling down, a great deal of models make noise. This is caused by thermal expansion and the ensuing reversal process. Although these noises are normally imperceptible, they may disrupt a peaceful night’s sleep if the device is left on overnight.

One of the drawbacks of the TEN is that its coils cannot be repaired; once they burn out, they need to be replaced. It is essential to have specialized and highly sophisticated equipment because it is just not possible to properly connect the tungsten filament and insulate the inner part of the tube at home (Fig. 6).

Figure 6

Convector heaters have received mostly favorable reviews. They are popular with dacha owners and with homeowners who don’t have autonomous or central heating. These kinds of devices offer a wide range of benefits.

Convector heaters are the best option when the room can only be heated by electricity; the benefits and drawbacks of these heaters are readily learned from the technical documentation that comes with them. You can effortlessly maintain the desired temperature thanks to high efficiency.

Device and principle of operation

What is the structure and operation of electric heating convectors? When the convector is disassembled, two modules are found inside: a control module with a thermostat and a heating module with an integrated heating element. When the heating element receives a voltage, it begins to function and heats up, distributing heat to the air inside the volume. Via the top vents, the heated air rushes upward and out. The intake of cold air comes from below, through the floor.

The electric converter is a simple device consisting of a heating element and control unit concealed behind a protective screen.

Thin metal casings are used in the manufacture of electric convectors. It is not advisable to burn oneself on them because the heating element’s maximum temperature is between +60 and +65 degrees. Heat transfer from the casing is essentially nonexistent in this regard. Warm air will, however, be felt rising if we place our hand up against the upper ventilation grille. It warms the people inside by moving around the heated space.

What is the foundation for this equipment’s operation principle? Everything is very basic here; convection of air occurs naturally. The air is heated by the heating element, which causes it to defy gravity and shoot upward, out the upper ventilation openings. The lower grille allows cold air to enter at the same time. In other words, nearly all of the air in the space is let through by electric convectors.

Without the need for fans, you can achieve quiet operation and softer, more even heating because of natural convection.

Like any heating system, convector heaters have advantages and disadvantages of their own. Nevertheless, they provide a practical and effective way to heat your house.

The quick and effective heating that convector heaters provide is one of their main benefits. Through the use of an electric element, they draw in cool air from the bottom, heat it up, and then release the heated air from the top. Convector heaters can swiftly increase a room’s temperature thanks to this process, which makes them perfect for providing on-demand heat.

The capacity of convector heaters to distribute warmth evenly throughout a space is another advantage. Convector heaters evenly distribute heat, making sure that every corner of the room is heated to the same degree, in contrast to some other types of heaters that could cause hot spots or uneven heating.

Additionally portable and reasonably small, convector heaters are simple to move from room to room as needed. This flexibility spares you from having to buy multiple heating systems by enabling you to target different areas of your home for heating.

Convector heaters do, however, have a few disadvantages to take into account. Their reliance on electricity is one common worry, as it can result in higher energy bills than other heating options, particularly if used frequently or for longer periods of time.

Furthermore, because they might find it difficult to sufficiently heat a larger space or a room with a high ceiling, convector heaters can be less effective in these situations. To guarantee the best level of comfort in these situations, additional heating sources or alternative heating systems might be required.

In conclusion, convector heaters are a popular option for many homeowners because they provide quick, effective, and reliable heating for smaller to medium-sized rooms. When determining whether they are the best heating option for your house, you should take into account their dependence on electricity and their inability to adequately heat larger areas.
