Infrared heaters are currently very popular among consumers. They can easily compete with any heating device. Such as an oil cooler, convectors, a split system with a heating system.
The principle of operation of heaters is based on the emission of infrared waves, which initially heat up the surrounding objects, and they, in turn, emit heat into the air of the room. Warm air rises upward and the entire space of the heated room is heated.
The radiated waves can be of different lengths. According to this principle, infrared heaters are:
Heating efficiency depends not only on the wavelength, but also on the area of the heated room.
Shortwave heaters are mainly used for small rooms and for local local heating, for example, outside in a gazebo, heating a certain place in the room. When using such a device, one must remember that the shorter the infrared wave, the more harmful it affects the human body. With prolonged exposure, waves can cause redness on the skin, dry the mucous membranes of the eyes and cause such a serious illness as cataracts. Therefore, if you need to heat a small house, dacha or apartment, a greenhouse in the country, it is better to purchase an infrared medium-wave heater.
They practically have no effect on the human body and are absolutely safe.
Long-wave infrared heaters are used for heating large rooms, mainly on an industrial scale.
Infrared heaters can be divided into three types depending on the energy source:
Let's take a closer look at each view.
Electric heaters are widely used in everyday life and industry.
As a heating element, spirals, threads or heating elements are used.
Electric IR heaters are:
They are designed for heating large rooms.
If infrared heaters are classified according to the heating element, they are:
The front panel of this type of heater is made mainly of ceramics, and you can also buy a stone panel made of marble, sandstone and quartz. Such models are produced in small sizes. They can be installed in the window-sill space, as well as models for floor and ceiling use.
Due to their low consumption, they are very convenient for heating small rooms. You can buy such a heater with any wavelength.
As a heating element such heaters used halogen lamps. They are glass tubes with tungsten filaments installed inside. When current flows, the filament heats up to a red glow, due to which infrared radiation occurs.
An inert gas is present in the tube to prevent overheating of the lamp and breakage of the tungsten filament. Therefore, in order for the heater to serve for a long time, it must be protected from mechanical damage, shock when dropped and liquids hit the lamps.
In life, such heaters are rarely used due to their high energy consumption.
Considered one of the varieties of halogen heaters. They differ in the design of the lamp.
Instead of a metal thread, these models use carbon mineral fiber.
Such heaters are produced with a different number of heating elements from 1 to 4 pieces in one model. The power of the heater depends on the number of elements.
The advantages of such heaters include:
This type is mostly used by summer residents to heat polycarbonate greenhouses.
Quartz heaters can be purchased in two types - tubular and monolithic.
Tubular heaters are somewhat similar in design to halogen heaters. The heating elements are tubes made of quartz glass, inside which a heating wire is placed. The efficiency of such heaters is much higher due to the use of quartz glass. At maximum power, the efficiency can reach up to 95%.
Monolithic heaters by design are solid platinum, in which the heating element is located. This is a conductor made of a chromium-nickel alloy. When this platinum is heated, infrared radiation is emitted. The construction of the monolith is protected from overheating and moisture. The efficiency of this series of heaters reaches 80%.
Externally, these heaters are similar to oil radiators.The design of the IR device consists of thin plates that serve as a conductor. The plates, in turn, consist of thin metal layers. When current flows, the plates conduct thermal IR waves and do not heat up at all. This is possible due to the fact that each plate is covered with a layer of mica.
In addition, each heater is equipped with metal grilles.
The design of the micathermic IR -device allows circulating heated air in the room according to the convector principle, which is one of the advantages of this heater. The efficiency of the devices is almost 98%. They are durable in operation.
These are heaters of high power and are usually used on an industrial scale.
The principle of operation of gas heaters is based on the process of combustion of gas (propane, butane, butylene, natural or liquefied gas) and air on special heater plates. When burned, the heating element heats up and emits heat in the form of infrared waves. By design, combustion chambers are of open or closed type.
Ceramic gas heaters can be referred to with an open chamber. They are available in both large and small sizes.
In domestic conditions, they are used as portable devices and are used to heat small rooms, summer cottages, utility rooms. In the process of gas combustion, combustion products are released. Therefore, the room to be heated must be well ventilated.
Tubular gas heaters have a closed combustion chamber. The heating element is tubes.
Air, moving through the tubes, gives them its energy and thereby increases the temperature of the outer walls to 300 degrees. The released heat is emitted in the form of infrared rays and moves to the bottom with the help of a reflector.
Heaters of such a plan are expensive to use and install. Therefore, their use in everyday life is limited.
These heaters are used to heat houses that are far from the electric network.
They are also called heat guns. During combustion, the heated fuel passes at high speed through a narrow nozzle and transfers heat to a metal grate, which is an emitter of IR rays. In this way, heated air is maximally distributed throughout the room. These devices are not used in a domestic environment. The disadvantages include high fuel consumption, noise and a good ventilation system.
Advantages of infrared heaters:
In the production of IR heaters, toxic substances are not used that can negatively affect the state of human health;
When choosing an IR device, it is necessary to take into account some points, namely:
Considering the above factors, you can choose the right infrared heater.
I purchased a heater for heating a bedroom 12kv. m. Beauty, very satisfied. Heats up very quickly, works without noise.
Occasionally only cracks after prolonged use. The body has a thermal sensor, which is convenient. It turns itself off. I recommend it to everyone!
Brought a 1500W Resant heater for heating the billiard room.
I thought it was not profitable to supply central heating. At first I didn't believe it would be warm. Billiard room 25 sq. m. As a result, super, the heater coped.
Maintains a stable 18-20 degrees.
Pros: warms up well, relatively portable thing.
Disadvantages: subjective - looks softly strong
We bought IR for heating a house.
Gas is expensive to conduct. Relatives recommended buying this device. We were very impressed with the quality of the panels. Heats up the room quickly. We have an insulated house, so we didn't have to wait long.
Pros: Does not take up space, economical, beautiful
Basically all buyers were satisfied with IR heaters. Their heating speed, ease of use and installation. Some praised it for its small size and economy. Ability not to "burn" oxygen in the air. The main thing is to choose the right heater for the heated area.
It has high efficiency, is mobile when moving, the service life, if used correctly, is up to 30 years;
