A brief overview of the micathermal heater: advantages and disadvantages as they are

What is a mikathermic heater

These devices can be considered a novelty in the market of heaters. They appeared thanks to developments in the field of space technology. The basis of the mikathermic device was an innovative heating element. Its feature is the use of mica, so this equipment is also called mica.

To date, there are two varieties of such a heating element, respectively, and two types of heaters.

The micathermal heater uses an innovative synthetic mica heating element. This allows you to significantly increase the efficiency of the device.

Initially, the device was a nickel heating plate, covered on both sides with layers of mica. The latter performed two functions at once: they isolated the heating element and transferred heat. To increase the efficiency of the device, additional ones made of a special alloy were subsequently added to the main heating element. Thus, devices of the second generation have a multilayer structure.

In them, between the mica plates and the nickel heating element, the inner and outer additional layers are placed. The function of the first is the reflection of heat. Due to this, the most complete return of infrared radiation to the surrounding space is achieved. The second layer provides an increase in thermal flows. The result is a more efficient heating element.

The action of mikathermic devices designed for space heating is directed at surrounding objects, which then transfer heat to the air mass.

Equipped with a mica heating element, the device transmits the most favorable radiation for people into the room, does not dry the air, does not burn dust

In 15 - 20 minutes after switching on, the heater reaches its operating temperature, electricity is consumed by almost three times less than oil heaters

The mikathermic heating device can be safely located not far from furniture made of natural wood, plastic trim, musical instruments that are sensitive to high temperatures.

Arguments in favor of heaters with a mica element

High speed of reaching operating temperature

Environment-friendly temperature range

The principle of operation of the device is very simple. When the device is turned on, the nickel plate begins to heat up. It transfers heat to the mica plates. The latter, in turn, evenly distribute energy and transmit it in the form of infrared radiation to all nearby objects that begin to heat up. The process is very fast. After turning on the device, the effect of its operation begins to be felt after a few minutes.

A feature of mycatemic heaters is that they transmit most of the thermal energy, about 80% of the generated energy, in the form of infrared radiation. The remaining 20% ​​is accounted for by heating the air around the device. The latter value is quite small, so mica heaters can be safely attributed to devices that work by means of infrared radiation.

Micathermal heaters of the latest generation are characterized by a multilayer heating element. Additional layers located in front of the mica enhance the reflection of infrared rays and distribute them extremely evenly

Micathermal heater or convector - which is better

Everyone decides for himself which heating equipment suits him.

Micathermal heaters delight consumers with fast warm-up and high efficiency. But when choosing equipment, many people begin to doubt what to choose - a convector or an infrared heater. We recommend relying on your own feelings. Convectors heat the air, thereby contributing to the appearance of an unpleasant sensation - for some it may seem “burnt” or dry. As for infrared devices, they often cause headaches and a sensation of a cotton head.

Both devices have every right to exist.Convectors do not worsen well-being, working like classic radiators. But the heating is extremely long, its first results become noticeable after at least an hour, depending on the area of ​​\u200b\u200bthe room. Micathermic mica heaters work noticeably faster, but can cause some discomfort.

If possible, we recommend that you purchase two devices at once and compare their effect, and then make the right choice.

Why Choose Mica Heaters?

The advantages of using mikathermic equipment are obvious. These include:

• Ecological safety. During operation, the device emits electromagnetic and infrared waves that are in a range that is safe for humans. The synthetic mica covering the heating element does not emit toxic substances.
• High heating rate. In the room processed by the device the set temperature is reached extremely quickly. This literally takes a matter of minutes.
• Profitability. The heating efficiency of the device, when compared with traditional appliances, is much higher with the same power, therefore, the equipment consumes 30% less electrical energy.
• Safety of use. Even with prolonged operation of the device, its body does not warm up above 60C. Therefore, it is impossible to get burned by accidentally touching it.
• Versatility. The device can be used indoors and outdoors. An example of the latter is a terrace, balcony or veranda. It can be used as a system that prevents the appearance of glaciation on the staircase.
• Silent operation.The manufacturer selects the thickness of the mica plates so that their thermal expansion coincides with the thermal expansion of the core. In this case, unpleasant clicks, which are inevitable during the operation of other electric heaters, are completely excluded.
• Light weight. This quality allows us to produce not only mobile floor models, but also wall models of various sizes.
• A variety of additional options available. These can be built-in thermostats, various timers and air ionizers. Convenient models equipped with shelves or folding dryers for clothes or shoes.
• Directed heating. The possibility of selective heating of individual sections of the room.

With a large number of advantages, mikathermic devices, unfortunately, are not ideal. They also have disadvantages. Directional heating is one of them. This means that the device heats only the area to which it is directed.

The farther from the heater, the less its work is felt. This disadvantage is especially noticeable for devices with a small area, which are able to heat only small sectors of the room.

Mica heaters are very efficient. With the same power as other heaters, they emit more heat, which saves about 30% of electricity

Despite the fact that mica does not attract dust, the latter still accumulates on the device. This is especially unpleasant for models with a large number of holes. When you turn it on for the first time after a long break, the dust begins to burn out and an unpleasant smell spreads around the room.

Another nuance is the heating of the case. The maximum temperature of its heating is small, but in some cases it can be dangerous.Some synthetic fabrics may melt and ignite if they come into contact with the body of the heater.

There is a possibility that certain types of furniture can also "respond" to the proximity of a heat source. Melting or ignition of PVC film and various plastics is not excluded. Therefore, such flammable items must be kept at least one meter away from the appliance.

Despite the fact that the case of mikathermic devices does not heat up much, for safety reasons, do not install the device close to flammable materials or hang clothes made of synthetic fabrics on its body.

What is better - a convector or a microthermal heater?

High-quality convectors are also sold at high price tags, so it is not advisable to raise the issue of cost in comparison. This equipment transfers up to 90% of thermal energy to the surrounding space, first the air volume is heated, and within a few hours the temperature equalizes between the objects and the gaseous medium. Micathermal heaters, on the other hand, act directly on objects that fall into the coverage area, the air remains cool. In both cases, heat exchange takes 2-5 hours.

The convector weighs more than a mica unit, but is also equipped with wheels or hung, that is, there is no need to carry it by hand. During the time it takes to fully warm up the room, both options consume approximately the same amount of electricity. They may also have identical additional options:

• display,
• thermostat,
• drying rack,
• smooth or step power adjustment,
• rollover protection,
• display.

Micathermic heater heats up the room faster

If you need fast heating, it is better to purchase a mikathermic apparatus, and for constant heating, a convector is more convenient.

Advantages and disadvantages of ceramic heaters

Even the most perfect design has its advantages and disadvantages. Ceramic heaters are no exception. Along with undeniable advantages, the devices have a number of significant disadvantages.

pros

The most significant advantages of ceramic heaters include:

• environmental safety. Ceramic plates are made from natural materials, therefore, even at a temperature of 800-1000C, they do not emit toxic compounds into the air. The use of ceramic heating devices does not pose a danger to humans and pets;
• high efficiency rates. For high-quality heaters, it ranges from 90 to 98%. This minimizes energy consumption;
• inertia of working elements. Details of devices do not oxidize and do not give in to corrosion, which increases the period of operation of heaters;
• the presence of a fan in many models. Forced air circulation promotes intensive heating of the room. Conventional fan heaters have the same advantages, but their efficiency is lower than that of ceramic heaters;
• high heat capacity of ceramics. The material is able to retain heat for a long time, which significantly reduces energy costs. Practice has shown that ceramic heaters are more economical than all existing analogues;
• compactness and ease of installation. Lightweight portable models can be used in different rooms as needed. Wall modifications are equipped with special mounting brackets that make it easy to install the device anywhere in the apartment;
• fast warm-up. This is achieved through a combination of infrared radiation and convection. Other types of heaters heat rooms more slowly;
• high aesthetic characteristics. In addition to their primary purpose, most ceramic heaters can serve as decorative items. Embossed or 3D-patterned faceplates add personality and style to any interior;

Minuses

There are few disadvantages of ceramic heaters, and yet they are:

• increased noise level. This applies only to heaters with a fan. The disadvantage can be considered conditional, since in high-quality models, the fan runs almost silently;
• energy intensity. Although ceramic appliances consume less electricity than other types of heaters, the electricity bill when using a ceramic heater increases markedly;
• low maintainability. The cost of repairing a failed device is quite high. In some cases, it is better to replace the product.

Against the background of the advantages listed above, the disadvantages of ceramic heaters can be considered insignificant. Customer reviews published on the Internet fully confirm this.

Pros and cons of a mikathermal heater

Let's turn to the advantages and disadvantages of mikathermic heaters for the full picture.

As for the pluses:

1. Profitability. The traditional type of heater consumes 30% more electricity, which significantly affects the owner's expenses.
2. Safety. The maximum heating temperature of the body of the device is about sixty degrees, which eliminates the possibility of burns.
3. Preservation of the microclimate in the room. Due to the principle of operation of the device, there is no combustion of oxygen at home. No matter how much the room warms up, there will be no lack of oxygen.
4. Noiselessness.The device can be installed in the bedroom, office, nursery. During operation, the device does not emit excessive noise.

What can be attributed to the minuses:

1. Heating only a certain area. The directional zone will heat up, but as it moves away from the heating device, the heat becomes insufficient. Away from the unit, there is almost no effect from the operation of the heater.
2. Radiating plates have several holes that get clogged with dust. Because of this, turning on the device may be accompanied by the smell of burnt fine particles.

Device and principle of operation

The principle of operation is based on infrared radiation and air convection

The heat source in the unit is a plate, which evenly distributes infrared rays. It consists of numerous metallic and non-metallic layers with mica coating on each side. Some layers serve to isolate, others to concentrate heat and reflect it. The plate radiates heat waves to the surrounding objects, heating them. As such, there is no coolant in the device, so there will be no problem with its burnout.

The layered element is enclosed in a metal case and equipped with gratings through which heat waves are distributed in two directions. There are models that direct heat only in one direction. They are hinged and convenient in that they save space. The third variety are cylindrical devices that have a circular IR radiation zone. They can be mounted to the ceiling or to the walls, depending on the characteristics of the room.

The devices are equipped with control units with a thermostat that allows you to adjust the temperature.There are models equipped with ionizers, shelves for drying items, as well as a water protection function that prevents the risk of damage to the device or a short circuit when moisture enters.

The principle of operation of the device is based not only on infrared radiation. A fifth of the performance is achieved by air convection due to the temperature difference.

The device is able to heat any surrounding objects - furniture, walls, people, animals. At the same time, inanimate objects themselves become a kind of heating pads - they transfer the accumulated heat to the surrounding air.

It turns out that the device heats the surrounding objects and air currents at a distance. This allows you to quickly heat the cold room in comparison with water, gas or electric convectors. Such heaters are able to heat only the air in contact with the coolant. However, in the case of the MC device, the heat flux density becomes smaller with increasing distance between the device and the object.

Manufacturers of innovative devices

Micathermal heaters are among the technical innovations, their release is still engaged in a relatively small number of companies. AiC, Poliaris, Bimatec and VES stand out among them.

AiC is an Italian brand that has located the production of its equipment in China. It produces heaters of medium power, with additional protection systems, a timer and a thermostat, which can operate in two heating modes.

The Israeli brand Polaris has also located its assembly plants in China. Its mikathermic equipment is characterized by high power.

In the line there are models that can heat rooms whose area exceeds 20 square meters. m.Devices of this brand are equipped with touch control panels, electronic thermostats, additional protection systems and have two operating modes.

Products under the Spanish brand VES are produced in the same China. Its distinctive feature is democratic prices. The line has interesting models that combine a mikathermal heater and a convector. Such a symbiosis significantly increases the efficiency of space heating. Most of the devices are produced in a waterproof case, have an average power and additional protection systems.

It must be admitted that companies that produce micathermic heaters produce devices with similar characteristics and functionality. The only significant difference is the case design.

The Bimatek brand is Russian, but production is located in Turkey and China. It produces high-quality equipment of medium power, capable of operating in three modes, with the possibility of programming and functional protection.

It is difficult to say which of the brands of mikathermic heaters is better. They differ little from each other in terms of functionality and quality. The main difference is in the hardware design.

Manufacturers overview

It is appropriate to start a review of micathermal heaters from the budget segment. And here the VES MX 1 deservedly takes the first place. It is recommended for work in production workshops and garages. The heater has a compact body. The distribution of thermal impulses occurs 360 degrees, that is, all areas of the room are covered. Since production was moved to Asia, it was possible to reduce the cost of the product to 3,800 rubles.

The diode indicator helps to control the current state of the device. Wide legs provide proper stability.Feedback on this device is positive. The manufacturer claims that the automation will immediately turn off the system if it is tilted or dropped.

A good alternative to the device described above is the DeLonghi HMP 1000. The proprietary automation is designed to turn on the device if the air is cooled to +5 degrees. It is provided, as in the previous model, to stop work in the event of a fall. Consumers have the opportunity to choose the type of installation: hanging on the wall or placing on a movable wheel frame. The largest allowable area of ​​​​the premises is 30 square meters. m. Thanks to the thermostat, the desired temperature is maintained autonomously. The mass of the device reaches 4 kg.

It is worth taking a closer look at the Polaris PMH 2005 mikathermic heater. Judging by the reviews, this device fully warms up the house in severe frosts. There are 2 modes, one of which allows you to cope with a slight cold. The wheels will help move the heater to the right place. The thermostat works reliably and stably.

The technical characteristics of the device are as follows:

• current consumption - 2 kW;

• heating power - 1500 or 2000 W;

• maximum heated area - 30 sq. m;

• implemented shutdown in case of excessive heating;

• device weight - 4.5 kg;

• floor placement.

According to experts, the DeLonghi HMP 1500 is better suited for additional heating of the bedroom in winter.

An important feature of this device is the black frame and medium-sized grille. These elements allow you to fit the heater into any stylistic direction. The device can be hung on the wall or on legs with wheels

Switches are conveniently located

The device can be hung on the wall or on legs with wheels. The switches are located quite conveniently.

Both the housing and the heating block are assembled very well. The power of the device allows you to both warm up a large room and save electricity. The designers have taken care that the grate is not pressed tightly against the heating part. An anti-freeze function has also been implemented.

The weaknesses of this model should also be kept in mind:

• when installed in the center of the room, the back panel will spoil the interior;

• no protection against overheating;

• no dust filter.

For the office segment, VES MX 5 is considered an ideal choice. This heater has a thin body and a strict, concise design. Thanks to the thoughtful design of the legs, a stable position of the device is guaranteed. The start button is located on the top. The front panel has a fine perforation and reliably protects the internal parts.

With a mass of 7 kg, this causes a lot of inconvenience. Also, this model does not have a thermostat.

If these parameters do not suit you, you need to pay attention to versions from the "expensive" segment. They are characterized by high power and more sophisticated functionality.

An expressive example is the Aic DF-HT6305P. This heater will allow you to enjoy comfort even in a spacious living room. Its characteristic feature is a presentable appearance (resembling a high black rack). The heater is controlled by sensors. The power of 2000 W is enough even to work in extreme cold.

Other advantages of the model are:

• adaptation of the resistance of the heating element to the conditions in the room;

• absolute fire safety;

• very long working life;

• purification of incoming air from dust;

• timer and protection systems against overheating;

• remote control.

For limited (25 sqm or less) space, the Polaris PMH 2095 is better suited. The production of this model is deployed in Germany. There are 4 plates hidden under the black case. A feature of the PMH 2095 is a fairly stable platform and wheels located on the sides. The design of the device is perfect for any room. The flow of current is recognized by the signals of the light indicator. It is possible to set the desired temperature through the panel.

It has three disadvantages:

• rather high price (at least 6000 rubles);

• a short power cord, forcing the usual use of carrying;

• clicking thermostat (interferes at night).

Harm of infrared waves for the body - a myth?

Infrared waves are traditional electromagnetic radiation, similar in structure to the sun's rays. The harm and benefits of infrared radiation are determined by the depth of penetration of these waves into the skin.

There are 3 types of heaters depending on from the wavelength and incandescent temperature of the heating element:

• devices with maximum heating up to 300 degrees and a wavelength of 50-200 microns;
• devices that heat up to 600 degrees, and with a wavelength of 2.5-50 microns;
• heaters with heating up to 800 degrees and a wavelength of 0.7-2.5 microns.

Those. the higher the incandescent temperature of the device, the more short waves will be emitted. For an ordinary healthy person, heat waves with a length of about 9.6 microns are safe. Manufacturers in technical device passport indicate the range of infrared radiation.

Information about the range of infrared radiation can be found in the accompanying documentation for heaters or on the product box. The absence of this information indicates significant violations on the part of the manufacturer.

Usually it varies between 2-10 microns. In this case, the intensity of IR radiation depends on the characteristics of the heated surface (especially its emissivity). The most powerful radiation comes from a heated black object.

Any prolonged targeted infrared radiation has a bad effect on the human body, which is expressed in:

• drying of the skin;
• decreased vision (with prolonged exposure, the risk of developing cataracts increases);
• violation of the structure of cell membranes (typical for short infrared waves), etc.

It is especially dangerous to install a powerful ceiling heater in a room with low ceilings. In this case, infrared rays will constantly heat the human head and can lead to the development of all kinds of diseases.

But these infrared heaters can bring real harm only in the case of a constant directed flow to a person. Ideally, devices should be installed so that the heaters give off their heat to walls or furniture, but are not directed at a person.

The heater should not always be directed at the person. Infrared is only useful in small amounts.

However, at the same time, in Japan and Europe, entire institutes are developing methods to fight cancer based on the influence of infrared radiation. In the course of scientific research, it has been proven that IR waves, reaching the inside of the skin by 14-20 cm, carry out effective cell detoxification.

This is due to selective hyperthermia, increased biochemical circulation and elimination of congestion in tissues. The result of the use of radiation depends on properly selected circuits, and a micathermic heater is absolutely safe for health, if common sense is used when installing it.

Conclusions and recommendations for selection

In our opinion, the main disadvantage of mikathermic heaters is the price comparable to expensive convector models. Other disadvantages are not so significant, especially if you choose the right device for power. Here are some recommendations for this:

The old selection method thermal power 100 W / 1 m² of area is not very appropriate here. Yes, a 2 kW appliance is enough to heat a 20 m² room, but the residents next to the heater will become hot and uncomfortable

Therefore, buy a product with switching modes.

When choosing, pay attention to the manufacturer's data. For example, for a 1.5 kW heater, the Polaris brand instruction indicates a room area of ​​24 m². Warning: in this case, the walls must be insulated.
Consider the features of the building and the purpose of heating

If the stone house is not insulated, then you can’t navigate according to the manufacturer’s characteristics - use the traditional calculation method. When heating a garage or workshop, a temperature of 20-24 ° C is not needed, you can take a heater of lower power.

In fact, the high-tech Mica-thermic heater differs little from other infrared "brothers" and inherits all the advantages and disadvantages. Against the background of other "innovations" like quartz panels, this product looks quite worthy. The best option is to combine electric heaters with another heating method - water or air. Then you are guaranteed to get the desired effect and be able to use energy sparingly.
