A heating device that gives off heat to the environment through infrared radiation is called an infrared heater. User feedback reports that the use of this heat emitter is much more efficient than others (for example, oil coolers, fan heaters, etc.).
The design of the device is quite simple: in closed types, a tubular electric heater is used, and in open types, a spiral in a quartz tube. To direct the flow of rays, a special reflector (screen) made of dense and heat-resistant metal is used.
What is infrared heating
Heat transfer when using IR heaters is not carried out directly from the heating element or tubes, but through heated surfaces and furniture. Radiation increases the temperature of all objects that are in its path.
The principle of operation is similar to the natural heating of surfaces from the rays of the sun.
When usedWith such a device in the room, the amount of oxygen does not decrease, and the humidity remains optimal.
The average savings on heating with such emitters is 50%. For the most beneficial use, you should consider the location and number of infrared heaters. User reviews report that with the right selection of equipment, the effect of its use occurs within a few minutes after launch.
Main types of heaters
By type of food they distinguish:
- Electrical. Most often they are used in domestic conditions.
- Gas infrared heaters. Reviews about these devices are very different. This type is most often used in open areas.
Besides this, the first group is subdivided:
- On ceramic emitters. The heating element in such a heater is a cable that is enclosed in a ceramic case. He, in turn, is not able to conduct currents, but does not prevent the propagation of the IR beam. Most often, these devices are used in residential premises or offices.
- Carbon heaters. Users highlight the cost-effectiveness of such models. Heat transfer is carried out through vacuum tubes, inside of which there is carbon or carbon fiber. The devices are widely used in medicine.
- Film. Such heaters resemble a flat rectangle and are often made in the form of paintings. Microheatersmounted on a special heat-resistant film. The maximum surface heating temperature is 75 °C.
The second type of heaters is used when working in open areas, and can also be installed in recreation areas.
Varieties for home use
All heaters can be conditionally divided into two groups: light and long-wave.
The characteristics of the first type are:
- high surface temperature of the emitter (up to 600 °C);
- multi-room heating capability.
The second group is less efficient, so they are often used to heat small spaces or greenhouses. An example is the Ballu infrared heater. Reviews about this device are mostly positive. Users say that it is inexpensive, safe, economical, heats up quickly, and has an aesthetic appearance.
Working principle
The basis of the operation of such heaters is the conversion of one type of energy (for example, electricity or fuel) into thermal radiation. The temperature of the heated plates averages 250°C. Rooms heated by infrared radiation retain heat for a long time.
Industrial heaters are also used for hardening concrete parts, drying painted parts, etc. Such devices work according to the standard principle.
Characteristics of some models
Among users, budget devices are becoming more and more popular - ceiling infraredheaters. Customer reviews confirm that their characteristics correspond to those declared by the manufacturer (if the power source is gas):
- Fuel consumption is low - only 300 g/h.
- Heat transfer occurs at a distance of 1 cm to 10 m.
- Heat transfer range - from 2 to 15 kW.
Features of infrared heaters
Wall heaters are suitable for both partial and full space heating. Ceiling infrared heaters are considered less effective. Customer reviews report that the power supply of the appliance also affects the efficiency.
Electric heaters are considered the most convenient and powerful. In addition to these, gas and modulated appliances are popular. The former are more practical, because they do not need to be connected to the mains and are able to heat a room in which there are no communications.
Modulated heaters are equipped with a special fan that contributes to the rapid and uniform distribution of warm air.
Outdoor gas infrared heaters are gaining more popularity. Reviews and recommendations about them are mostly positive. Users say that they are reliable, look stylish and heat the space well. This unit consists of:
- from the body;
- gas tank;
- burners;
- emitter.
Modern outdoor heaters are made in various designs - from the most primitive,rectangular to compact, lamp-shaped or bowl-shaped.
Ease of use, absolute fire safety and economy are key features.
How to choose the right infrared heater: reviews and user tips
When choosing, consider:
- The power of the device. This criterion is selected depending on the area of the room and the presence of other sources of thermal radiation.
- Reviews indicate that floor heaters are much more powerful than wall or ceiling heaters.
- If there are frequent power outages in the area, gas heating systems should be chosen.
- When choosing a gas heater, you should take into account the additional area for the placement of cylinders.
- For greater ease of use, you can purchase an infrared heater with a thermostat. User reviews also leaned in favor of devices with control panels and other automation.
Advantages and disadvantages to use
Key advantage in use is economy. Other characteristics include the following:
- heater does not dry out the air;
- safe to use;
- the device is suitable for both combined and individual use;
- heater is made of environmentally friendly products;
- the device does not make noise during operation;
- room heats up in minutes;
- heating quality is not affected by extraneous factors (such as drafts);
- IKthe heater consumes almost 80% less electricity than a fan heater;
- mobility (the device can be moved to any distance without effort).
In addition to a number of advantages, the devices also have disadvantages. According to reviews, infrared heater:
- has a spot heating system;
- waves emitted by the device adversely affect vision;
- due to uneven heating of the room, various fungi and mold may appear;
- the heater does not dry out the air, but the surfaces (because of this, the furniture loses its properties, the equipment may fail).
Rating of infrared heaters
Mobile heating devices are widely used in both domestic and industrial environments. The rating among users is as follows:
- In the first place is Electrolux EIH/AG2-2000E. The Swedish manufacturer has earned the trust among citizens for good reason, because the device has sufficient power - 2 kW and a 1 kW mode. Manual temperature control is possible. Also, the system has built-in protection against hypothermia and overheating. Among the advantages: a large service area - up to 25 m2, mobility, compactness. The main disadvantages of the reviews are the high noise level during operation, the lack of rollover protection.
- The second position is occupied by an infrared heater Ballu BIH. Reviews report the following: the device can be mounted both on the wall and on the ceiling. In spite ofcompactness, the device can heat a room up to 20 m22. Among other advantages: low cost, high-quality assembly, protection of the case from moisture, ease of installation and operation.
- One of the best ceiling heaters is "Resanta IKO-2000". This device is able to evenly heat a room up to 20 m22. Among other advantages: compactness, ease of installation and maintenance, nice design. The key disadvantages are: high cost and lack of a thermostat.
- Mister Heat refers to wall mounted infrared heaters. Reviews about the device are also positive. This unit is economical and consumes only 100 watts of energy per hour of operation. The temperature can be adjusted manually. Other advantages: excellent build quality, modern design, simple operation, wide temperature range.
- The last position in the ranking is occupied by Royal Clima. The main advantages are: low cost, attractive design, high power and the possibility of various installation options. The disadvantage is the lack of a temperature sensor.
Important! Portable models of heaters of any kind can be equipped with tripods for installing the device. The tripod, in turn, is adjustable in height. This feature allows you to use the units with maximum comfort. It is possible to install several heaters on one support.
