Advantages and disadvantages of the model range
Strengths of monolithic sand radiators:
- affordable price range;
- simplicity of design - the absence of external working elements facilitates maintenance and cleaning;
- with the correct choice of the number and performance of heaters, it is possible to ensure rapid heating of rooms even in harsh climatic conditions;
- devices operate silently;
- The use of natural materials in the production ensures the environmental friendliness of the composition.
Quartz batteries have a good price and operate silently.
Disadvantages of the solution:
- radiators are heavy and require the most durable fasteners;
- budget variations can be recognized by their unattractive appearance;
- the surface becomes very hot, which can cause a burn if touched accidentally. Such performance is undesirable for families with small children. But the vulnerability can be eliminated with the help of an additional protective screen;
- the slabs are fragile, require careful transportation and careful installation, cracks often form on them after the first heating;
- For ease of use, you will have to purchase a thermostat separately.
Questions may also arise regarding the build quality of monolithic equipment. Flaws are especially noticeable on the back side (poorly made frames, cracks, peeling paint).
Infrared devices also operate silently, but they have a better design. The advantages of their use:
- complete heating of surfaces, and not transfer of thermal energy to the air;
- mobility, low dead weight;
- attractive performance;
- wide range of brands and models;
- safety of use;
- built-in thermostat;
- compact dimensions.
The cost of such devices is higher than stove-top ones, but they do not require the additional purchase of a thermostat. The only drawback is that the heating of the room volume is not as fast as compared to the previous option.
Principle of operation
The operating principle of quartz heaters is simple. The nichrome spiral heats up to the temperature required for operation (about 95 degrees). At the same time, infrared rays are generated, which, acting on objects in the room, heat their surface. At the same time, the convection process occurs - cold air from the room is drawn into the lower part of the device, and then, when heated, it exits through the holes in the upper part. That is, effective mixing of air masses occurs, and, as a result, more comfortable heating of the room.
Almost all models of quartz batteries are not equipped with thermostats. This means that you cannot regulate the temperature in the room yourself. A panel with sand can maintain a high temperature for a long time, so you will constantly need to disconnect the device from the network. The solution may be to purchase a thermostat and install it to the heater. Most manufacturers provide this option.
A quartz heater can be used either in addition to a standard heating system or as an independent equipment. For large rooms, several quartz devices are connected in parallel to form a single module.
Advantages of quartz radiators
Quartz batteries have many advantages over other types of electric heating devices:
1. Economical. Economical energy consumption can be called a key advantage of quartz devices, since other types of electrical heating devices consume a significant amount of energy, thereby negating all their other advantages. The cost of electricity is always high. Therefore, most of the population tries not to use electricity to heat residential premises, despite the fact that electric heaters are environmentally friendly and easy to operate.
Types of heating radiators
Quartz batteries consume a minimal amount of electricity, and they can be safely used both as additional heaters and as main heating devices. They do not create a big burden on the family budget.
2.Large heat capacity. Quartz slab has great thermal inertia. It takes a long time to heat up and takes a very long time to cool down.
3.Durability. The heating element has no contact with the environment, which prevents its oxidation and increases its service life.
4. Possibility of connecting a thermostat, which provides automatic control of the heating system.
5. Relatively low price compared to electric water heaters and other efficient heating devices.
6. Fire safety. The temperature of the working surface of the quartz battery does not rise above 95 degrees, so the ignition of materials located in the immediate vicinity of the heater is completely excluded. The device can be mounted on a wooden surface, lining, or drywall.
7. Electrical safety. The device does not create large loads on the electrical network and can operate non-stop throughout the heating season.
8.Easy installation. The quartz battery is attached to the wall with brackets.
9. They are not demanding to care for and do not require maintenance. Caring for a quartz battery is limited to removing dust with a dry cloth.
A quartz battery can be installed in the same way as conventional radiators, under a window sill, so that it creates a thermal curtain and prevents cold air from penetrating through window openings. If the room is large, you can install two quartz batteries and connect them to one thermostat, then it will regulate the temperature on both devices. Using quartz radiators for heating is much more profitable than installing a water heater in the house and spending money on installing a water heating system.
The cost of paying utility bills when using an electric water heater for heating will be very significant.
All the advantages of a heater with quartz sand
Now let's look at what the manufacturers say. The listed advantages of the heater, with which I agree:
- fire safety; heating is not performed above 95 C;
- high heat capacity;
- comfort, reliability, ease of operation;
- significant operating time of the built-in element, without stops and breaks all season;
- possibility of use as an auxiliary element, as an addition to an existing heating system;
- decorative effect of the perforated screen for harmonious inclusion in the interior;
- no need to acquire a massive water boiler, pipes, radiators and other equipment required for other types of heating;
- mounted on any surfaces and materials;
- can be installed on the floor, on a stand, or hung from the wall with brackets;
- in each room you can set your own mode, which allows you to provide selective heating of individual rooms in a country house, production workshop, garage, or country house;
- the set temperature is automatically maintained for a long time, even in the absence of homeowners, thereby eliminating dampness and freezing;
- the air does not dry out;
- the dust is not burned, a feeling of freshness remains;
- The efficiency of the device is extremely high: there is an almost complete conversion of electrical energy into thermal energy with minimal losses;
- maintenance is limited to periodic removal of dust when switched off;
- access of air to the heating element is excluded, which prevents oxidation; service life is extended to unlimited limits;
- control is carried out optionally - manually or automatically;
- with a special attachment it is used to warm up a car engine;
- does not require special maintenance personnel or special measures to maintain stable operation;
- absolute environmental friendliness;
- An air sensor with a thermostat allows the system to turn on and off independently when the temperature reaches the required limits - minimum or maximum.
Where is it used?
In conditions of 30 degrees below zero, this heater is unlikely to be able to completely replace other types of heating; in such cases, it can only be used as an additional source of heat.
You can choose any texture for the heater
A quartz heater has no equal when it is necessary to provide heat to a separate area of the room, for example, a PC operator’s place in a warehouse or a bathroom. In such conditions, he shows all his positive qualities to the fullest. It is fireproof, not afraid of moisture and cooling, starts working almost instantly and does not dry out the air.
How to install a heater
This type of heating is used quite actively in country houses and dachas, when gas supply, and even more so central heating, is not cost-effective. After all, we very rarely visit such houses in the winter, and investing in capital improvements to the heating system is an unacceptable waste. Arriving at your country house for the weekend, you can warm up in a matter of minutes just by flipping the switch on your quartz batteries.
Organizations that connect various options for a smart home system also actively use quartz radiators in their projects. Firstly because of their durability, and secondly because of their resistance to repeated on/off cycles. Using a thermostat and modern wireless network capabilities, such systems can easily be set to stand-by mode when people are away from home and maintain a set fairly low temperature (for example, 5-7 degrees), practically not turning on until the owners arrive.
How to choose
First, you must know the area of the heated room. In your calculations, proceed from the principle that a power of 0.5 kW will be enough for you to heat an area of 10 square meters. The design of the quartz slab does not matter at all; the main thing is that its coating is made of high-quality hypoallergenic materials that will not deteriorate and emit odor when exposed to high temperatures.
Pay attention to the weight of the heater. The indicated power is 500 W - weight is at least 10 kg. In general, the more weight, the better.
Take the stove in your hands. Under no circumstances should anything fall out of it. Spilling sand and dusty marks on the fingers are a sure sign of a homemade heating device. It's better not to take this one.
Opt for trusted manufacturers Teplolit, TeplEko, Supra, etc., who provide a guarantee on their products and have been leading the market for many years.
Unfortunately, it is impossible to completely protect yourself from purchasing a low-quality heater by performing a visual inspection. Many manufacturers, trying to reduce the cost of goods, do not use quartz sand in their panels, but regular sand. Also, such companies can use marble chips as a filler. Both options are much cheaper, but the performance of such devices is very low.
Try to buy products from well-known brands, and if this is not possible, do not buy painted products - this is how unscrupulous “basement cooperatives” hide the real contents of their panels.
Installation features
When planning heating, it is worth taking measurements of the rooms and installing heaters based on the following principles:
- Up to 10 sq.m. – one heater, power 500 W
- From 10 to 15 sq.m. – two heaters 400 W each
- From 15 to 20 sq.m. – two heaters of 500 W each
- From 20 sq.m. – one 500W for every 7 sq.m.
At the same time, they bring the greatest efficiency if they stand opposite each other, and the thermostat is in the middle between them.
The heater is mounted on the wall using three or four brackets, but before that you should prepare the wall. To do this, you must apply a heat-reflecting screen to its surface, which is inexpensive, but returns up to 30% of the heat to the room.
Heater with reflective screen on the wall
It is better to connect quartz heaters with a separate cable connected to a separate package, because the load during their operation will exceed the normal load on the electrical network produced by household appliances.
Because The heater is flat - it takes up practically no space in the room, however, it is not advisable to press it against the wall, because this will lead to a significant decrease in efficiency and you will not get any heat. Manufacturers supply their heaters with special brackets, which determine the optimal distance to the wall. This should not be neglected.
Which heater is better - recommendations for choosing
If you find it difficult to choose between a monolithic and infrared heating device, then read our recommendations on this matter:
- When installing permanent electric heating in a private house or country house, it is better to buy stationary quartz heaters in the form of stoves. One condition: the products must be in harmony with the interior, otherwise you should think about another heating method.
- For local and temporary heating of people in any premises and outdoors, a quartz heater of the UFO type is perfect.
- The best way to use monolithic panels is in combination with other heating systems. For example, during the day the house is heated by a stove or boiler, and at night - by quartz heaters, and even at a cheap rate.
- Do not rely on infrared heating as the main method of heating a country house or country house where you visit. While the infrared devices warm up the building well, you will have time to finish your business and head back.
- Regardless of the type of quartz heater, select the right devices based on power. Do not believe or think that one 400 W stove will provide heat in a 10 m² room at a frost of -5 ° C and below. She barely has enough “strength” to slightly raise the temperature and prevent you from freezing.
Heating with several panels together with water radiators (standing behind the screens)
One of the main recommendations is not to believe numerous advertising statements of this kind:
- our panel heats up in 20 minutes and cools down for an hour, continuously releasing heat;
- our heater is 30-50% more economical than others;
- a 500 W device is enough to heat a room of 10-12 m² (in reality - no more than 7 m²);
- Our heater generates no more than 2.5 kW of electricity per day, and it’s hot in the apartment!
Counting example. For a room of 10 m² with a ceiling height of 2.7 m, on the coldest days you will need 10 x 2.7 x 40 = 1100 W of heat (that is, the same amount of electricity). In this situation, 2 monolithic heaters of 400 W each will work without interruption, wind up 0.8 x 24 = 19 kW per day and will not reach a comfortable temperature. But even if we take not the maximum, but the average heat consumption for the season and divide 1100 W in half, then we will have to spend 550 x 24 = 13200 W = 13.2 kW of heat per day on heating, no matter how you look at it.
It is too expensive to heat large rooms with quartz appliances, unless you arrange local heating
How to determine the power of the heater?
One of the basic criteria for choosing any heating equipment is the power required to maintain a comfortable microclimate in the room where it is planned to be installed.
And this is where buyers often fall for the marketing tricks of manufacturers who, although not particularly distorting the information, still try to attribute completely indescribable qualities to their products. Thus, one can come across the statement that quartz monolithic devices are almost twice as powerful as all others in terms of heating power, and at the same time figures are given that a 500-watt panel is capable of heating a room of 14÷18 m³.

Characteristics
Heating convectors and heaters "Tepleko" have quite good characteristics in their class. To fully appreciate all the qualities of the product, you need to know what characteristics the selected device has. It is also advisable to compare them with similar ones from another - a heater that has the following indicators:
- energy consumption (kW per day) - 2.5;
- complete cooling time - 5 hours;
- power level - 400 W;
- total weight - 12 kilograms;
- Estimated cost: 2300 rubles*.
Important! The Teplotek heater has a direct competitor from Teploplit, which has approximately identical performance, but is a little more expensive and cools faster
In domestic conditions, fierce competition has developed between the two manufacturing enterprises. Teplotek heaters have lower power, but are more economical than TeploPlit. In the manufacturing process of the former, quartz sand is used in increased quantities, which contributes to greater heat accumulation. For example, the Tepleko electric heater is capable of storing heat for five hours, while its competitor is only 2.2 hours. In terms of cost, both devices are approximately within the same range, from 2300 to 2500 rubles per unit.
Types and principle of operation
A quartz heater can be monolithic or infrared.
Monolithic (MKTEN)
It is a slab made of quartz sand solution with a nichrome spiral installed inside. After connecting to the power supply, the spiral heats up and transfers heat to the base plate. Quartz has a high heat capacity, so even after turning off the device, the air in the room will continue to heat up for some time. Such products take the form of a flat (about 25-30 mm) panel, which is either attached to the wall using special brackets or equipped with a stand for installation on the floor.
The device is valued by consumers for the following advantages:
- You can paint it any color - this procedure is provided by the manufacturer.
- The heating element is protected from contact with air and therefore does not oxidize, which ensures a long service life.
- If the device falls and depressurization occurs, there will be no leakage of toxic substances.
- The heat reserve lasts about 1.5 hours, and the device can cool down for up to 5 hours, depending on the specific model.
- The presence of a temperature sensor.
- Fireproof.
- There is no risk of short circuit.
- Minimum probability of spiral burnout, thereby increasing service life.
- Moisture-proof heating element - can be mounted in the kitchen and even in the bathroom.
- Maximum heating of the stove is achieved within 20 minutes after being plugged in.
But the device is not without its drawbacks:
- Difficult to move from one place to another.
- Heavy weight (up to 13 kg) – complexity of installation and limited number of places where installation is possible (plasterboard, for example, will not withstand such loads).
- The surface heats up to 80-120 °C, you can get burned.
- In homes with children and animals, installation is possible only with a protective screen.
Infrared
The device works by heating a spiral made of tungsten, nichrome or carbon, which is placed in a quartz tube. This type of heater produces electromagnetic radiation in the infrared range. Surfaces in the room absorb energy, heat up and release heat to the air.
The principle of heating through infrared radiation is more productive than convection: only the “useful” area is heated, energy is not wasted on unused ceiling space.
The infrared quartz heater has the following advantages:
- The light weight allows you to install the product yourself, even on the ceiling.
- Fire safety.
- Silence.
- Inertia.
- Environmentally friendly.
- Can be stationary or portable.
- Thermostat and remote control function.
- Possibility to heat only part of the room.
But it also has disadvantages:
- The tube heats up strongly during operation of the device - up to 700 ° C, and dust settling on it emits an unpleasant odor.
- The instability of a quartz tube to changes in temperature and humidity quickly loses its technical characteristics when working in difficult conditions.
Expert opinion Vasily Stepanovich Kuznetsov Manufacturers smooth out the shortcomings of the infrared device by producing models with a heating element mounted in an anodized profile. This device is fireproof. There is a small minus - slight crackling during operation.
Criterias of choice
When choosing this or that type of heater, you need to take into account several criteria:
Type
Of all the listed types of heaters, you should choose the one that best suits the technical characteristics for your dacha. The power of the device is important. There is a simple formula that helps to correctly calculate power
For 1 m2 of living space, 100 W of power is required. In addition, it is important to pay attention to the type of installation: floor, wall, ceiling, tabletop
Performance
In the instructions for the device, the manufacturer indicates what comfortable and maximum area of the room it can heat. Knowing this characteristic, it will be easy to choose the best option for your dacha.
Control
More budget models are equipped with a mechanical type of adjustment. It is a set of knobs, switches and buttons. Such devices are designed to operate in a given mode and can turn off when a certain temperature level is reached. The adjustment is rough and the scale is indicated as simply as possible - from minimum to maximum.
Modern models have a digital display and can be adjusted using touch or mechanical buttons. Their capabilities are much wider than standard options, because they can:
- turn on and off by timer;
- automatically maintain the set temperature;
- show the current air temperature.
For ease of use and setup, a remote control is included. But there are also the most advanced models. They have a built-in Wi-Fi or Bluetooth transmitter that allows you to control the device via a smartphone.
Functions
Depends on the complexity of the model. Simple devices are equipped with a thermostat that regulates the intensity of work and turns the device on and off at a certain interval. In advanced models, switching on and off occurs based on environmental conditions. Delayed start, scheduled on and off, remote control - these and other functions are included in heaters with an electronic control system.
Noisiness
The technical specifications must indicate the noise level of the electric heater. The quietest are infrared, then oil and convection. The noisiest ones are fan heaters.
Protection
Many models are equipped with a sensor or fuse that trips when the device overheats. Some have protection that turns off the heater if it falls. If there are children or elderly people in the family, then it is better to choose a wall-mounted type of equipment.
Comments:
Rodion
Good review, although I didn’t notice any special features of this type of heater. I installed both convectors and quartz ones - the electricity consumption is almost the same. The only difference is the price.
Jack
Rodion, I don’t know about you, but I feel the difference. Quartz is much heavier and produces 20 percent more heat at the same electricity costs
TeplopitBel
The patent for the Quartz electric heater belongs only to the manufacturer from Belarus - TeplopitBel. https://teplopit.bel This is how TeplopitBel-Belarus differs from its Russian counterparts. 1. Electricity consumption of TeplopitBel (250 W/hour) is 1.5 times less than that of Russian ones. 2. Heat transfer is 1.5 times greater than that of Russian ones (due to the composition of the purest quartz sand). 3. The radiating surface area is 1.5 times larger due to the coating with natural material (natural mountain stone). 4. Cools down 30% slower in time (after complete shutdown) due to the increased area of the radiating surface. 5. Heats a room twice as large with an area of 10-12 sq.m. in contrast to the Russian analogue (5 sq.m). 6. The appearance of the heater does not require a decorative screen. The savings are double at the same price. https://teplopit.bel

Don't take JUNK FROM CLOWNS WITH TEPLEKO SEE OUR BELARUSIAN Quartz heater with Patent and documents
Stepan from St. Petersburg
Tepleko is produced in Kemerovo by individual entrepreneur Kotenkov (type all the information on the Internet) Here they are, factory ones with short wires without a plug, selling them to TD TEPLEKO on a simplified single tax - distribution and difference trade. And there's not even a cash register. Not provided due to low turnover.
And that’s what they have a Patent for on an electric heater... For water or for what??? And where is the Patent for the Quartz heater... SHOW. If there is no Patent (for a Quartz heater), don’t write that you are producing them. Or don’t screw up everyone who makes analogues.
THE COOL FACTORY Tepleko DOESN'T EVEN HAVE A CASH REGISTER - ONLY A SINGLE TAX!!! Like our entrepreneurs at the market in the Republic of Belarus (only ours even have a cash register). Like delivering pizza to apartments. They are always on PROMOTION. There is no receipt and no guarantee as for PROMOTIONS. They are registered as delivery and differential trade.

People, be vigilant, avoid this sharazhka's office! For them, the customer is always wrong; after the acquisition, you are enemy No. 1 for them! I learned this the hard way, the website says a 3-year warranty, but I purchased it a month and a half ago and it turns out that for some reason this warranty does not apply to me! All the good reviews are written by the company employees themselves, they are hired there specifically for this purpose, it is IMPOSSIBLE to leave a bad review on their website, they call back and start threatening!…

Individual cottages are not connected to the main heating organization; for this reason, they request installation of independent heating. The core component of your own heating network is undoubtedly the boiler, which heats the coolant. There are quite a lot of models of this type of equipment on sale, which seriously complicates the choice. It is very important to approach the process of purchasing a boiler wisely, since this is the only way to design your home to be warm and cozy. Let's look at some likely options!

But having purchased Tepleko, you need to immediately take care of concluding an installation agreement with an organization that has the 3rd approval for the installation of electrical appliances. Otherwise there will be no guarantee. Yes, Tepleko also has promotions all year round. Promotional items are not subject to warranty anyway. We played it safe. So get ready to immediately purchase from Tepleko a non-warranty product that can be used with cracks (written in the passport). Who gave them the Certificate? It is not clear how such offices generally work. Tepleko is a Lego constructor and a circle of skillful hands.
Valentina
For example, if you bought from Tepleko, then you also need to invite a company to connect and draw up an Acceptance Certificate for connecting the Tepleko heater (this service is not cheap - like the heater itself). Otherwise there is no guarantee. That's it gentlemen!!! And Tepleko has a promotion for a whole year. This means that in any case (even with an official connection) you have no guarantee. There is no guarantee on the Promotion. This is how, gentlemen, it turns out to be twice as expensive to buy Tepleko. You also need to additionally buy a plug and screw it yourself, mounts and a reflector on the wall. Total price is 2700 from Tepleko. And TeplopitBel sells its heaters (in bulk) twice as economically for 1,800 rubles. Here's the schedule for you. One TeplopitBel warms like two Tepleko. And in terms of area, TeplopitBel is designed for 10-12 sq.m. and Tepleko for 5 sq.m.
Anatoly
Tepleko-RF has a lot of shortcomings. That's why. Write to yourself. First of all, this is the most important thing. Tepleko does not have a Patent for a Quartz heater (Tepleko has a Patent for an Electric Heater) - You are misleading buyers. The patent for a quartz heater is only available from TeplopitBel from Minsk. Secondly, you add marble chips yourself (all this is written on your old website), and this reduces the thermal conductivity of the heaters. Further more…. — Tepleko consumes 20% more than stated (measure the resistance). — Operation with cracks (written in the passport) is just crazy (How did you get the Certificate???). - Lack of any guarantee (written in the passport - connection only through a company with an additional payment). Buyers don't know this yet. — Cable 50cm. without a plug (Who issued you a Certificate for the electrical device???) - Lack of a plug on the cable (you have to buy it and screw it yourself???). — Additionally, buy brackets and a reflector. — Cracks in 99%. — Heating area 5 square meters. — Lack of stores with real purchases and selection on site (only through mail via the online store). Whatever comes in the mail cannot be returned. Maybe it’s enough to list? Or maybe a dozen more.

Just recently I bought myself a Tepleko heater, so overall the heater is 5 out of 5, it’s just perfect, there are some small nuances but they don’t affect anything, because the heater heats up very quickly, now my room sometimes turns into a bathhouse so I have to turn it off and even open the window, in general I need to buy another thermostat in order to sleep comfortably.
Heater TeplopitBel
Energy-saving Quartz heater TeplopitBel with built-in thermostat for heating
TeplopitBel quartz heaters are made of quartz sand. Energy-saving convectors are suitable for heating all premises: gymnasiums, shops, offices, apartments, houses, restaurants, garages, universities, gymnasiums, schools, sanatoriums, kindergartens.
The heating element of the TeplopitBel monolithic plate consists of an alloy of chromium and nickel. It is sealed so that air does not penetrate to it. Therefore, it can easily withstand high temperatures.
TeplopitBel is a unique device. It does not create noise, does not generate dust, does not dry out the air in the room, and concentrates slow cooling and rapid heating.
We recommend installing energy-saving convectors parallel to each other in order to significantly increase the activity and quality of their work. If you decide to purchase a thermostat, it is better that it is located between the heating devices. The thermostat helps save electricity and stabilizes the temperature of electric heaters.
TeplopitBel is easily mounted on walls using several fasteners. We do not recommend pressing the unit very tightly against the wall, as this will certainly lead to a significant decrease in efficiency levels.
Advantages of heating units: reliability, durability, fire resistance, provision of a comfortable microclimate, frost resistance.
Before installing the electric battery, it is worth preparing it by measuring two centimeters between the heat device and the wall on which the installation will be carried out.
The temperature regime of an energy-saving convector can be regulated much more quickly using a thermostat. How to use a temperature sensor? Set any temperature on it. When this device “decides” that there is as much heat in the room as needed, it will turn off on its own.
A modern heat and power generator, decorated with attractive embossing, created according to a special recipe. You can choose any of 3 models: with a consumption of three hundred watts per hour, two hundred fifty watts per hour, four hundred watts per hour.
The cost of a quartz heater, which was created in Belarus, will please every buyer. Anyone who is outraged by the price of a wall-mounted unit, know that it is fairly compensated by reliability, high quality and beautiful design. Regular customers are guaranteed a nice discount! Come, choose and buy! We are sincerely glad to see every visitor!

Manufacturers and model overview
Currently, the heating appliance market offers models of quartz heaters not only from Russia, but also from Europe. The most popular manufacturers are:
- "Thermoquartz";
- "Exo";
- "Prometheus";
- "Texture";
- "WarmHoff";
- "Equation"
Let's consider the most popular models of monolithic quartz devices.
"TeploplitBel"
The model is produced for installation in bathrooms, as this device is not afraid of moisture. The heater allows you to heat small bathrooms and toilet rooms without using stationary heating. This can be relevant not only in private houses, but also in cold corner apartments in panel houses.
The power of this quartz heater is only 0.25 kW. This is very little (that’s how much two incandescent lamps consume), which means that the device can be left running constantly without fear of a significant increase in electricity bills.
The advantages of the model include:
- the ability to choose a decorative panel to match the color and design of the walls in the room;
- optimal panel thickness (2.5 cm) takes a long time to cool down after switching off;
- reaches maximum operating temperature in 25 minutes;
- small sizes – 60x34 cm;
- operates smoothly even with voltage surges from 207 to 250 Volts;
- optimally suited for rooms up to 10 square meters with a ceiling height of no more than 3 meters.
The disadvantages of this model include the weight - it is 11 kilograms, and the absence of a regulator for the operation of the device.
"TepplEco"
This model is also recommended by the manufacturer for installation in bathrooms. Its rated power is only 400 watts, but this is enough to heat small bathrooms and provide a comfortable temperature there.
The quartz slab in TeplEko is placed in a metal frame, which is coated with powder paint. This allows you to protect the product body from corrosion under operating conditions with high humidity.
The advantages of the model include:
- beautiful appearance and interesting design;
- conveniently located power button on the side of the device;
- thin body – only 2.5 cm;
- continues to heat the room even after an hour and a half after being disconnected from the network;
- does not dry out the air;
- reaches operating temperature in 18-20 minutes;
- a well-insulated housing eliminates the possibility of moisture getting inside the heater;
- dimensions – 60x35 cm;
- Perfect for rooms up to 18 square meters.
The model has few disadvantages. Among them:
- no thermostat;
- the weight of one panel is about 12 kg, so they cannot be used for wall placement, especially on plasterboard walls.
"Improved heat stoves"
Recommended by the manufacturer as a heat source in corridors and spacious halls of country houses and apartments. A distinctive feature of this model is its design - the main color is replete with small black inclusions that imitate natural stone. This device will fit perfectly into any interior. This is an excellent option for heating a room when it is inconvenient to pull pipes into the corridor or they spoil the appearance of the room.
“Improved heat stoves” have the following advantages:
- The kit includes a 1.5 meter long wire and a plug for connecting to the mains;
- safe when used near upholstered furniture, textiles and soft toys;
- wide range of colors;
- cools down within 2 hours, continuing to heat the room all this time;
- does not burn oxygen and does not dry out the air;
- easy to install - it has only 3 points for fixation;
- capable of heating a room of 12-15 square meters;
- consumes only 0.4 kW per hour;
- The surface layer made of natural material prolongs the cooling time of the device, which makes it more economical.
The disadvantages include:
- a small manufacturer’s warranty - only 2 years from the date of start of operation;
- must be supplemented with a foil screen at the rear wall for more efficient operation;
- no thermostat;
- The weight of the panel is 10 kilograms, so when mounted on the wall it must be strong. Modern plasterboard walls simply cannot withstand such weight.
Design features and technical characteristics
Before we consider the quartz heater, the pros and cons of this device for the home, let’s determine the design features and technical characteristics. For production, natural 100% quartz sand, kaolin (special white clay) and other fire-resistant binders are used. After mixing, the solution is poured into flat molds with a pre-laid nichrome heating spiral. The mixture is tamped to remove all air bubbles and is first dried and then sintered. All this ensures maximum strength of the finished panel and excellent thermal properties, thanks to which quartz panels are one of the best for home heating today.
The resulting device can be called a dry analogue of an oil radiator - when turned on, the nichrome spiral heats up, and the heat is transferred to the quartz mass. But quartz has a high heat capacity; it is able to accumulate heat, maintaining its temperature for a long time after being turned off. The cooling time is up to one and a half hours, which allows you to further save energy by creating an optimal microclimate in the room. But, unlike oil radiators, the possibility of breakdown and leaks is excluded for quartz panels. That is, you don’t have to worry that the heater will be damaged if dropped or accidentally hit.
A big advantage is the design of the heating device, which meets all modern requirements. The rough surface has pleasant color schemes; it will harmonize with any interior, giving it more coziness and comfort.

Universal monolithic quartz heater Tepleko
The versatile Tepleko quartz heater will solve heat problems in a room of 15-20 square meters. Using economical and inexpensive batteries, you can heat a small dacha, country house or apartments in high-rise buildings. Using the equipment is not difficult, and all installation work and configuration of the device can be done independently.
Monolithic quartz heaters Tepleko are economical and compact equipment, characterized by versatility of use. These devices consist of a coiled cable that emits heat when electricity is passed through it. The heating element is in a shell made of compressed quartz sand and marble chips; it retains heat for a long time, warming the room even after the heater is turned off.
Technical characteristics of the Tepleko heater:
- Heater power - 400 Watt.
- Energy consumption per day is 2.5−3.5 kW.
- The weight of the device is 12 kilograms.
Thanks to their excellent thermal inertia, such heaters will be an excellent option for country houses and holiday villages where there may be power outages. Even if there is a power outage for 60-90 minutes, the heater will be able to heat the room using the energy it saves.
The operating principle of the Tepleko monolithic quartz heater is extremely simple. Inside the durable panel there is a spiral heater, which, when current is passed through it, can heat up to a temperature of 95 degrees. A chromium-nickel rod is used as a thermal element, which allows to significantly reduce electricity consumption in comparison with classic heaters with heating elements.
From the heated cable, heat is transferred to the quartz panel, and is subsequently slowly released into the room, maintaining the temperature at a comfortable level. On sale you can find numerous modifications of Tepleko batteries, which will differ in their power, size and functionality.
The popularity of heaters of this type is due to their numerous advantages. The advantages of Tepleko include the following:
- Completely silent heating.
- High reliability and durability.
- Excellent efficiency indicators.
- Fire safety and high-quality insulation of the heating wire.
- High moisture protection.
- Affordable price.
During use, the quartz monolithic heater does not dry out the air, which allows for comfortable indoor conditions. Thanks to its excellent power, such a heater will solve heat problems in rooms up to 20 square meters.
One of the advantages of this modification of heaters is not only their efficiency, but also the minimal load on the electrical wiring. At dachas and in old houses, where the quality of the electrical network leaves much to be desired, it is not possible to use powerful heaters. The Tepleko quartz heater in this case will be the ideal choice, guaranteeing complete safety of heating.
One of the disadvantages is the lack of thermostats in basic models of heaters. Accordingly, it is impossible to regulate the temperature in the room. You can connect an external thermostat to the heater, but additional wiring will be required, and the cost of such control modules can reach up to a thousand rubles.
Disadvantages also include the mediocre speed of heating the room. It takes at least 30 minutes for the heater to reach its maximum power, and only after that the rapid heating of the room begins.
Wall heaters operating on the principle of directed infrared radiation
Device design
There is no doubt at all that the very idea of such heating devices is borrowed from the principle of transmitting solar energy. Despite the enormous distance (about 150 million kilometers) between the Sun and the Earth, the rays reaching the surface of our planet cause its heating and are, in fact, the basis for the existence of biological life itself in all its diversity. Atmospheric air is not a significant obstacle to radiation energy - it is heated only in a fairly thin surface layer, receiving thermal energy from the earth and water surfaces heated by infrared rays. By the way, it is the infrared component that accounts for about half of all radiant energy transmitted by solar rays.
Solar infrared rays are the best example of the transfer of thermal energy over vast distances
It has long been noted that a person’s comfortable perception of the environment is influenced not only by air temperature, but also by direct infrared radiation. For example, on a very cool spring or autumn day, but with calm wind and bright sun, the overall feeling may be close to summer. An even more obvious example is “alpine tanning”, when people at ski resorts, dressed for the beach, at negative air temperatures, but with a high sun, sunbathe without any inconvenience.
Prices for Polaris quartz heaters
Quartz heaters Polaris
It is this principle of heat transfer that is implemented in household appliances equipped with heating elements in a sealed quartz glass housing. The prototype of modern heaters of this class can be considered reflectors, familiar to many from childhood. This is a parabolic metal reflector with a regular cartridge in the center. A heating element was screwed into the cartridge - a conical ceramic base with a wound spiral.
Surely, many people once used such primitive, but at the same time quite effective heaters
Despite all their simplicity, one cannot fail to note the extremely low level of safety of such primitive reflectors. Moreover, both from the point of view of the occurrence of a fire hazardous situation, and from the standpoint of the high probability of accidental burns or electrical injury. Plus, an open spiral means constantly burning dust, dry air, unpleasant odors and other “pleasures”.
Over time, these pronounced shortcomings were eliminated by placing the open spiral in a sealed case made of quartz transparent glass. The level of operational safety has increased significantly as a result, with virtually no loss in the efficiency of beam energy transmission. These heaters came to be called quartz heaters precisely for this design feature.
The design of such a heating device is very simple.
The design of an infrared heater-emitter is not particularly complicated
Typically, such heaters are assembled in a metal or plastic heat-resistant housing (item 1). If the heater is intended for wall placement (on the topic of our article), then holders or brackets (item 2) should be provided on the back, usually with the ability to change the direction of the flow of rays vertically.
The main working unit is one or several quartz glass tubes, hermetically sealed, with a heating element placed inside (item 3).
As a heater, ordinary metal spirals made of an alloy with high electrical resistance can be used - most often it is nichrome (an alloy of nickel and chromium). They give off a characteristic bright red glow. The radiation is located closer to the visible part of the spectrum, refers to short-wave infrared rays, which are still considered “harsh”, burning for comfortable perception.
Heating elements with nichrome (left) and carbon spirals
Heating elements made of carbon fibers are more advanced in this regard - they have a darker glow, the emitted wavelength is longer, and the sensations from such a flow are more pleasant.
If the device is considered specifically as a heater, and not a powerful lamp, then halogen heating elements are definitely not suitable
But what is completely unsuitable for normal heating purposes are tubular elements of the halogen type, in which a high-temperature tungsten spiral is placed in a quartz transparent casing in a special gas environment - by analogy with conventional incandescent lamps. This element produces a very bright glow, and is more suitable for a spotlight. Of course, the heat flow released is also very powerful, but it will hardly be pleasant for the heater to blind your eyes. Radiation is the harshest, often causing even painful sensations on delicate areas of the skin and extremely unpleasant for the eyes.
Let's return to the diagram. Behind the heating elements there is always a reflector (item 4). Its configuration is designed so that the flow of beam energy is directed in a certain sector in the desired direction. The reflector can be glass, but it will probably be more durable if it is made of metal - made of a plate polished to a mirror finish.
The operation of such devices always involves heating to very high temperatures. In order to ensure at least minimal safety, the heating elements are covered with a safety grille on the front side (item 5).
Control of such heaters often comes down to just turning the power on and off. However, there are also devices that provide for stepwise switching of the heating power - one or more heating elements are put into operation, or the voltage supplied to the coils is changed.
However, many modern household models also have a built-in thermostat that will automatically supply or turn off power depending on the temperature level in the room. The difficulty, however, is that the pronounced directional action of such heaters can lead to a rather incorrect analysis of the temperature in the room. Therefore, it is still more advisable to connect such devices to an external thermostatic control module.
Model equipped with a built-in electromechanical thermostat
But in any case, the use of a built-in or remote thermostat when operating such a device indoors leads to economical consumption of electricity. And on this basis, such heaters can be classified as energy-saving.
The range of such heaters is quite large, but compact portable models of tabletop or floor-mounted design, or devices for stationary ceiling installation, still prevail. Wall-mounted ones are not so common, simply because of the pronounced direction of action and the inevitably created “dead zones” where infrared rays do not reach. Although, you can try to find the optimal installation location on the wall. In any case, in addition to wall-mounted models, the possibility of such installation is provided in some floor-mounted (rack-mount) or ceiling-mounted devices.
Advantages and disadvantages of quartz infrared heaters
What advantages do heating devices of this operating principle have?
- The tangible effect from the switched on device begins to be felt almost immediately - it takes literally a few seconds for the heating element to reach operating temperature.
- Such a heating device is capable of creating a dedicated “increased comfort” zone. For example, in a home workshop, when there is no need to warm up the entire space, an infrared reflector can provide good heating in the work area.
- Infrared heaters are perfect for suburban conditions. For example, infrared heaters with a thermostat for a summer residence are suitable if there is no possibility, desire or need to equip a full-fledged heating system. When visiting their “possessions” periodically during the cold season, it is enough for the owners to turn on such heating so that acceptable, and after some time, quite comfortable conditions of stay are created in the premises quickly enough. At the same time, the device itself is quite compact, and it is not necessary to leave it at an unguarded dacha - you can bring it with you and hang it on the wall in a place that has already been prepared.
An infrared wall-mounted quartz heater will create comfortable conditions for relaxation even in open areas - in a gazebo or on the veranda.
- It has already been said that the perception of heat consists of the level of ambient air temperature and the influence of infrared flow. This means that such a device can be placed in places of traditional outdoor recreation in order to spend time comfortably even on very cool evenings. This quality of similar devices. By the way, the owners of cafes with tables located in open areas often use them.
- The operation of the device is completely silent.
- The efficiency of such heaters tends to 100%. However, this is typical for most modern climate control devices.
Modern models can be equipped with built-in thermostats, digital indication of operating modes and remote controls
- Some models are equipped with remote controls, which greatly simplifies the operation of a heater located at a height.
At the same time, quartz infrared heaters also have very significant disadvantages :
- The radiation itself, most of which falls in the visible part of the spectrum of sunlight (red glow), is not optimal for human perception. This drawback is more pronounced in heaters with metal spirals, and to a lesser extent in heaters with carbon ones. A constant red glow can be irritating. Especially at night. Moreover, such irritation may not only be of a “psychological nature” - some people, especially those prone to allergic reactions, may experience pain in the eyes and lacrimation.
The characteristic glow of a quartz infrared heater at night may well cause irritation
- Quartz heating elements reach high temperatures and accidental contact with them will result in serious burns. This is especially true in those houses or apartments where young children grow up. An external grille is unlikely to guarantee safety. This means that the device either cannot be left unattended, or it should be placed on the wall at a height inaccessible to children’s pranks.
- High heating temperatures are also a definite fire hazard. Lumps of dust or, for example, poplar fluff caught under the grate may well ignite.
- Quartz housings of heating elements are quite fragile, which requires special care during transportation, installation of the device, and during its operation.
- The directionality of infrared heating can also be considered as a disadvantage - some areas of the room can be cool, and when exposed to direct rays, it can be uncomfortably hot. It is not recommended to install such heaters permanently in the direction of a sleeping or permanent workplace.
Wall-mounted infrared devices quite often disharmonize with the overall design style of the living room
- Not everyone likes the wall arrangement of such devices - it can disrupt the intended interior style of the room.
Obviously, the disadvantages are quite serious, so you need to carefully weigh the pros and cons when planning to purchase a similar device for wall-mounted installation. Perhaps another, more acceptable and safer option will be found. But for a country house, this is probably one of the most optimal solutions.

How does a quartz heater work?
The operating principle of a quartz sand heater is based on the use of infrared directed radiation. Essentially, a natural process is used. In a similar way, the sun warms the earth.
Infrared quartz heaters are designed as follows:
- Heating element - made of an alloy of chromium and nickel. Quartz sand provides protection from the external environment and increased heat transfer. The heating element is placed in the lamp bulb or placed in a monolithic quartz slab.
Diffuser - behind the flask or plate, there is a metal plate that plays the role of a kind of mirror. Infrared rays are reflected from the surface, which provides directional radiation.
Thermostat - allows you to reduce the cost of heating the room by 30-40%. Some models operate in completely autonomous mode, thanks to the built-in control unit; others require a thermostat to be connected. To increase safety, the heaters are equipped with sensors that protect the surface from overheating.
Cost-effectiveness, safety and long service life are made possible thanks to the use of quartz filler. It was observed that sand heats up quickly and retains heat even after the heating source is turned off.
Heater models based on quartz sand, after switching on, reach operating power in about 20 minutes. The temperature of the heating element reaches 95°C.
Heating element design
Convectors from almost all manufacturers have a similar heating element, which is based on an incandescent filament. This can be a tungsten filament (the most durable and efficient in terms of heat generation), nichrome (cheaper, less durable and effective) or steel (the simplest, bulkiest and has the shortest service life).
Steel spirals are practically not used in convectors due to their bulkiness, but can be used in other devices. The first two types, on the contrary, are widely used in the production of convectors, and regardless of the material of the heating coil, the technical documentation indicates that the material is tungsten.
It is impossible for the average person to distinguish one material from another without special laboratory instruments, which is what sellers use. But there is still one indirect sign. This is the service life and warranty period of the heater. Since tungsten is a very refractory material, it has a much longer service life as a heating element than nichrome. Modern NOBO electric convectors, which use tungsten filament, have a warranty period of 10 and sometimes 12 years, and a service life of 30 years. A nichrome spiral will not work that long.
Leaving the filament open to contact with air guarantees the effect of “burning oxygen,” and the high temperature of the filament will ensure rapid “drying of the air.” To avoid this, the filament is placed in a tube. The space between the tube and the thread is filled with quartz sand. To increase heat transfer from such a heating element, the tube itself is made into a single stamped or solid piece with fins. It is the fins that provide a larger area of heat exchange between the electric heater and the air and, accordingly, faster heating of the room.
In the photo: Design of the heating element of the Nobo convector
The one-piece design of the tube and fins completely eliminates cracking due to linear expansion of the metal during heating and cooling. Aluminum alloys are used as materials for these elements as they are the most efficient in terms of heat transfer.
The design of the heating element is not always solid. Often, for reasons of economy, a tube is used from one material, and fins from another. Different linear expansions of materials often lead to their movement relative to each other, which can cause slight crackling sounds.
The heating element of quartz heaters is designed somewhat differently. Most often, a nichrome filament is also used in its manufacture. Under the influence of electric current, it heats up, increasing the temperature of the heater body. Moreover, the heating element is located over the entire surface of the device and there may be a small air gap between them.
The body of such a heater is made of quartz. Considering the principle of operation, the entire design of the device can be called a heating element. Any device that heats up as an electric current passes through it can be used as a heating element. Thus, there are quartz heaters where an IR emitter is used as a heating element, which heats the intermediate surface using infrared rays. This could be the outer casing of the heater or any reflective surface that heats the air. For this reason, such a heater can also be called infrared, since the principle of its operation is based on infrared radiation.

Monolithic
The design of a monolithic quartz heater consists of a tungsten filament, laid “snake” evenly over the area and poured into a slab made of a special compound based on quartz sand. The device is energy saving and reliable. When an electric current is connected to the contacts of the heater, the filament glows and transfers thermal energy to the stove. The surface of the slab gives off heat, the block itself plays the role of an energy accumulator (a type of hot brick). Thus, a monolithic quartz heater is one of the types of convector.
Heat is distributed from the device according to the principle of moving heated air and replacing it with a colder flow coming from below. The movement of air masses is a constant cycle - warm air rises to the ceiling, is displaced by new portions coming from the device, moves to the other end of the room, cools down and comes back to the heater, after which the cycle repeats.
The disadvantage of such a device is that the smallest particles of dust, various suspensions and microbes move along with air currents, so it is recommended to keep the room clean and ventilate it more often.
Monolithic heaters are installed in the lower tiers of the room so as not to accumulate warm air under the ceiling. There are floor-mounted and wall-mounted options for devices that are convenient from a practical point of view. The plate has a thickness of 2.5 cm, with dimensions of 60 by 35 cm.
Two main types of heaters that fit the definition of “quartz”
First, you need to decide what is generally meant by the term quartz heaters. And here a “surprise” will immediately await us - it turns out that this name combines two categories of heating electrical appliances. It is interesting that they even received the name “quartz” according to completely different evaluation criteria. And in their fundamental design, in the method of heat transfer, and in the basic rules of installation and operation, there are more differences than similarities.
Yes, the heat transfer used in both cases is based on infrared radiation. But, firstly, it varies significantly in wavelength and, accordingly, in its external perception by a person. And secondly, in one of the cases such radiation is, in fact, the only way of heat transfer, and in the other it is also combined with direct heat exchange, creating, among other things, convection air flows.
So, the concept of household quartz heaters is usually understood as the following devices:
An infrared device in which the main elements are heaters in a tubular housing made of quartz glass.
- Devices, the main working unit of which is a heating element enclosed in a sealed tube made of transparent quartz glass. The remaining parts of the device are mainly designed to focus and transmit infrared radiation generated by the quartz element in a given direction. For such pronounced features, such devices are often called reflectors.
Monolithic quartz panel
- Household appliances, which are a solid panel on a quartz base, inside which is a conventional resistive heating element.
As you can see, there are very few similarities between the devices, and the name “quartz” has completely different “origins”. Therefore, further consideration will have to be carried out for each category separately.
