- These are heating devices that transfer the heat they produce to surrounding objects through infrared radiation. This radiation, like sunlight, is invisible, is not absorbed by the air and reaches the lower part of the room without loss, warming up the floor, furniture, walls and interior elements located in the coverage area of the device. In infrared heaters, up to 90% of the energy is converted into a stream of long-wavelength heat rays and only 10% is spent on heating the air next to the heater.
Thus, the heat from the infrared heater is distributed evenly throughout the entire radiation zone, does not depend on air flows and ceiling heights, and creates comfortable conditions for people by heating the floor, and not the air at head level.
Thanks to this principle of operation, an infrared heater can be used where another heating method is difficult, impossible or economically unjustified: in rooms with very high ceilings or large heat losses (ventilated, heavily glazed, etc.); in semi-open and open verandas, terraces, halls; on open air; in rooms where zonal or even spot heating is needed. Other advantages of infrared heaters include efficiency, convenience, safety, ease of use and maintenance, compactness and noiselessness.
A wide range and range of uses means that for each specific case of installing an infrared heater, it is necessary to make a calculation and select the device model that will optimally satisfy the heat needs. A model for an industrial warehouse, an open pavilion or a small cafe will differ significantly in characteristics.
How to choose an infrared heater?
The choice of heater will depend on several main criteria:
- type of premises (residential, office, trade pavilion, warehouse, etc.)
- heating options (full, additional, zone, spot, etc.)
- installation heights (ceiling heights),
- installation (ceiling, wall, built-in)
- distances to people present in the room
- energy source (electricity, hot water, liquefied gas, diesel)
Power of infrared heaters
Having first determined the total power for heating the room as a whole, you can then select the power and number of heaters needed to distribute heat evenly in the room. In order to calculate how much heater power is needed for your room, the power density is calculated (the amount of power per square meter of heated area), which is measured in W/m2. The table shows approximate power densities to achieve the desired temperature in rooms with different thermal insulation.
The temperature indicated in the table may seem insufficient, but it should be remembered that with infrared heating, the ambient temperature feels 3-4° C higher than it actually is.
Heating area of infrared heaters
These recommendations for choosing infrared heating are of a general nature and cannot take into account all the features of your actual operating conditions. For advice and calculations, please contact our specialists.
With the onset of cold weather in our country, the heating season begins. People think about ways to heat rooms and choose the most optimal type of heater. The device can be purchased for different purposes:
- for space heating;
- to maintain a comfortable temperature in it;
- as an additional source of heat when the main one is insufficient.
All heaters differ in type of design and method of operation. There are four of them in total:
- Oily. They are considered the most affordable and simplest in design. They are distinguished by mobility, noiselessness, and environmental friendliness.
- Convector. Provides heating and air circulation. Takes up little space and is easy to use. But it is only suitable for small rooms and sometimes dries out the air.
- Fan heater. It has an operating principle similar to a conventional fan. It is characterized by its small dimensions and quick heating of a small room. But there is a minus - it dries out the air.
- Infrared. They affect surrounding objects, which then give off heat. It does not dry out the air, is absolutely safe and evenly warms the room.
Best Inexpensive Infrared Heaters
An infrared heater is a device that consists of a steel body and a quartz tube, protected on top by a grille. An infrared heater heats everything that is next to it (furniture, walls and floors), and not the surrounding air. It is more suitable for heating small spaces. Its use is possible both in closed and open spaces.

Convector
The operating principle of the convector is based on a simple law of physics. Cold air naturally enters the device from below. After this, heating occurs inside the housing and, already heated, it exits through the upper grilles (at an angle) into the ceiling.
The case itself does not heat up as much as in radiator models. It is the air that heats up. 
The truth is that the room does not warm up immediately. Unless there is an additional fan built inside.
If you come home from work to a cold apartment and turn on the convector, then the floor of the house will be cold for a very long time. 
Moreover, at a small height from the floor there will also be a layer of cold air.
The warmest place in this case is the ceiling. If there is even a small draft, it will be quite difficult to warm up the walls and furniture in the room.
Almost all convectors are wall-mounted, but some are also equipped with legs. 
Remember the rule that the lower the convector is installed, the more efficiently it will work out its kilowatts.
The wall-mounted installation option looks very aesthetically pleasing, but moving it from the bedroom to the living room or kitchen will no longer work.
The main heating element of a convector is a spiral. Therefore, such devices also burn oxygen. 
But recently, heaters with a tube consisting of a large number of fins have increasingly begun to be used. 
Thanks to this, even during long-term operation, their body does not heat up more than 90 C. And for many models, the temperature is even less than +55-60 degrees.
Such options will be a good solution for families with small children.
When installing heating in a bathroom, make sure that the model has a minimum degree of protection IP24.
What do these numbers mean?
The first digit indicates that the device is protected from penetration of solid objects larger than 12mm in size. For example, the fingers of an adult.
The second number (4) indicates that the heater is protected from splashing water from any direction. 
How much it will actually cost you to heat your home with convectors as the main source of heat can be found out from this video:
Infrared heaters
Most people are still wary of infrared models. Their operating principle is somewhat similar to the sun. 
The infrared radiation of the lamps does not heat the air in the room, but the objects located in it, which then give off heat to the surrounding space. Heating occurs due to invisible rays in the infrared spectrum.
You need to get used to this. The feeling under the heater itself will be as if you were sitting near a stove. One side is fried and the other is at room temperature. 
To protect yourself from the effects of such equipment, follow basic rules of use.
If you stay under such a heater for a very long time, you may feel a headache and fatigue.
However, the same thing happens from prolonged exposure to the sun or when sitting for a long time near an open fire. 
In addition, the infrared spectrum in excess quantities can negatively affect the skin. Such a beam is capable of penetrating to a depth of several centimeters under the skin and only then releasing heat from the inside, heading to the outer surface of the skin.
Everything here depends on the power of the source and the duration of stay under it. If you follow the instructions, then you should not be afraid of such radiation. How to protect yourself?
The most important thing is to maintain a minimum distance from the infrared heater. It must be at least 2 meters. 
The advantages of infrared technology include:
- instant heat
- almost complete absence of oxygen loss
- no odor
- noiselessness
And as numerous tests show, such heating is the most fireproof. Even if you place a Christmas tree directly under an infrared heater (right up to its touching the protective screen), setting it on fire will be problematic. 
Just don’t try to purposefully repeat such experiments at home. Heater is different from heater, and compliance with safety regulations should come first. 
The device is lightweight. It can be equally successfully placed on the walls or ceiling (hung on mounting chains like a fluorescent lamp).
So fix it on special legs. 
However, there are also some peculiarities. One of the disadvantages is that the effectiveness of the device is limited by the dispersion angle.
Step outside this zone and you will immediately feel a temperature difference of several degrees. IR heaters were created from the very beginning specifically for warming up work areas only in rooms without heating. 
To improve the heating efficiency when suspended from the ceiling, you can paint the floors a dark color.
There are also models made from ceramic plates, which also emit infrared thermal radiation, plus they look beautiful. 
They have low power and are resistant to moisture. Therefore, they can be safely used in the bathroom.
Similar models of infrared heaters can be installed in children's rooms, on balconies and even outside in gazebos.
Oil heater
The operating principle of an oil heater is somewhat similar to a conventional battery. First, the heating element heats up. Then mineral oil from it. Then the radiator housing and only lastly the surrounding air.
Therefore, the oil radiator warms up the room rather slowly. 
It may take about an hour before you feel warm. However, after switching off, it does not cool down quickly either.
So, a comfortable temperature in the room remains for a long time. It is believed that oil heaters do not “burn” oxygen and dust in the air, at least to the same extent as a fan heater. This is not entirely true. Indeed, there is no unpleasant odor from them. 
However, if such a battery operates continuously in the bedroom, you will wake up with a heavy head.
There should also be a minimum of noise. If it is noisy, this indicates its “quality”.
Most likely, the mineral oil inside is mixed with water. When overheated above 90 degrees, such a mixture inside already begins to boil and click.
Oil radiators are also resistant to tilting and falling. The element that heats the oil is located at the bottom of the device so that the hot liquid rises up by itself. 
If you place the device on its side or tip it over (your child may accidentally do this), an air pocket will form next to the heating element. 
A spiral not cooled by oil will quickly overheat and even a small explosion is quite possible.
To make matters worse, the oil spills onto the floor and begins to fuel the fire. Therefore, such a seemingly “safe” device must be treated with extreme caution. 
And it is better not to use them for longer than 5-7 years. Even if they still heat properly. Firstly, the oil in them gradually evaporates. Secondly, the internal wiring dries out and the contacts burn out.
Fan heater
In fan heaters, air is heated using a hot electric coil and a fan that drives air through it.
The room gets warm quite quickly, but when you turn it off it also gets cold quickly.
Since the coil is very hot, this type of heater dries out the air and burns house dust.
As a result, specific odors appear. Therefore, in recent years, models with a ceramic heating element that are free of these disadvantages have become widespread. 
In addition, the fan heater makes quite a noticeable noise during operation. So you won't get much sleep at night with him.
But its obvious advantages are its compact size and low cost.
During the cold season, residents of private houses think about a comfortable indoor temperature. But among the many heating equipment, it is difficult to choose the best option. Many people choose electrical products that have many benefits and consume a small amount of electricity. Let's consider which heater is the most economical for a private home in terms of electricity.
Which heater is the most energy efficient?
Before the start of the heating season, it is worth considering in advance which equipment will be optimal for your home.
There are several types of heaters:
- Electric (convector).
- Infrared.
- Micathermic.
- Air conditioner.
- Ceramic plate (panel).

Infrared heater
Oil and electrical products have been replaced by a new type of heating equipment. The energy consumption of such equipment is significantly less. A quartz emitter is a heating element that heats up and transfers heat to nearby objects. Such equipment does not heat the air. It is suitable for quickly heating a room. But it is not able to efficiently heat the entire house for a long time.
The infrared device can be installed outdoors. The equipment can be mounted to the ceiling or installed on legs. For heating a room up to 20 square meters. m. it will take 2 hours.
Popular models: Eko, Saturn, Beko, etc. The product consumes an average of 90 W per sq.m.

Micathermic heater
This product is distinguished by its economy and efficiency. It was developed using new technology and was released not so long ago. The equipment was previously used in astronautics and medical institutions. The equipment can be installed on the ceiling or wall.
A micathermic heater heats up efficiently because it has several plates that are coated with mica. It is safe as it does not get hot. Objects around the device heat up evenly.
There is one drawback in the equipment - high cost. A high-quality model is a product from Polaris with a power of 1.8 kW.

Air conditioner
The air conditioner is distinguished by its efficiency. Often used to heat a country house. The equipment consists of an indoor and outdoor unit. Heating a room is different from other heating devices.
The air conditioner is powered by a heat pump. It takes warm air inside the room using a heat exchanger. Therefore, even at negative temperatures, the air heats up and enters the house already warm. Freon is used for heating. Under the influence of pressure, the gas passes through the indoor unit in the heat exchanger and heats up to 80 degrees. After this, the freon passes into the outer part and returns to the gas under low pressure. After boiling, it flows again into the indoor unit.
From 2 to 5 kW of electricity is consumed per hour, depending on the model. Air conditioners can heat houses even with a large area. Popular models: Samsung, Daikin and LG.

Ceramic panel
Such equipment is also considered economical. The device looks like a ceramic plate. It works on the principle of long-wave infrared radiation. Excellent for different interiors, as it has a steel heat-conducting box. The panel can be installed on a wall or ceiling.
To calculate electricity consumption, it is necessary to take into account the dimensions of the device. On average, the panel consumes 0.2-2.5 kW per hour. Room 20 sq. m. can fully warm up after 2 hours.

Which heater consumes less electricity for a summer house and other homes?
Based on many experiments, one type can be identified that consumes less electricity. Such a device is a convector. The operating principle is similar to an oil radiator, but is distinguished by its safety and modernity.
Air circulates through the heating element, which is located in the convector. Thus, heat exchange occurs. The convector can be left on for a long time unattended, as it is one of the safest devices.
Such heating equipment is ideal for a country house. It does not dry the air, and the heating temperature cannot exceed 60 o C. After turning on the convector, the room will begin to heat up in 20 minutes. It consumes 25% less electricity than other heating devices.
The convector is considered the most economical for the home.
How much does an oil heater consume per day?
This type of heater burns a small amount of oxygen and consumes little electricity. In addition, they are not as fire hazardous as other devices.
The disadvantages are high cost and heavy weight. On average, an oil heater consumes 750W per hour. More powerful heaters consume about 1 kW. But you can find devices with less power.
Since the device operates several hours a day, electricity consumption is significantly less.
Oil heater
The higher the power of the device, the more electricity it consumes. When the device is turned off and in rest mode, it does not waste energy. Despite some disadvantages, there are more advantages. That is why it is popular among residents of private houses. You can calculate the amount of electricity consumed after 1 month of using the device.
Calculation of the power of different types of heaters per room area
Heaters are used not only in country houses, but also in apartments. In the fall, when cold weather sets in, the heating in the apartment is not yet turned on, so many people purchase electrical products. But in order not to receive a large electricity bill, you need to calculate the power and consumption of the device in advance.
To calculate, you should take into account the area of the house or apartment and the number of heating appliances. It is necessary to calculate the power of radiators using a special formula.
kWt = 0.277*c* ϱ *P*h*(t2-t1), where c is the specific heat capacity, ϱ is the air density, P is the area, h is the height.
As a result, you will receive the amount of heat needed to heat the house and the required power of the appliances.
Power table per room area
The formula must take into account the following points:
- Wall material and thickness. In a house with thick walls, heat loss will be minimal. And with thin walls, heat goes outside.
- Type of radiators. Batteries can be infrared or oil.
- Insulation of walls.
- The quality and quantity of windows in the house. A large amount of heat escapes through windows. Therefore, it is important that the windows are of good quality. In this case, the heater can be heated to a low temperature. And if the windows are ventilated, then you need to turn on the device at the maximum temperature.
In order to correctly calculate the power of the required heater with all the nuances, you can use a calculator.
Quartz heater power
Such equipment consumes a small amount of electricity. The average consumption is 0.5 kW per hour. The type of heater is different from the same oil heater. A special stove contains a heating element that heats up and emits heat. Heat is distributed evenly over the entire area.
Quartz devices have the following advantages:
- The heater does not dry the air. Therefore, people in the room will feel comfortable.
- Beautiful appearance.
- Long service life.
- The air in the house remains fresh and clean.
- The device does not heat up to high temperatures. It can heat up to a temperature of 95 o C. Therefore, such a product can be considered not fire hazardous.
- The equipment accumulates heat for a long time. The appliance heats up and remains warm for a long time. It will take 20 minutes for the quartz product to fully heat up.

Oil heater power
Based on the calculations, you can determine the power of the device. But it is worth considering the fact that such heaters distribute heat unevenly.
The air around the appliance becomes very hot, but in remote parts of the house the air remains cool.
How much energy does an infrared heater consume?
On average, such a heater consumes 0.5 kW per hour. This indicator indicates a high efficiency compared to other heating devices. If it works for about 10 hours a day, then it will consume 150 kWh per month. This electricity consumption can be considered a good indicator.
When purchasing a heater, you need to pay attention to the electricity consumption and power of the device. When choosing an infrared heater, power calculations must be made taking into account the area of the room, so as not to overpay for unnecessary electricity consumption.
