Harmful and beneficial heat of halogen heaters

There are too many conflicting reviews about halogen heaters. Some say that this is “sheer evil” and that they are harmful to humans, others are quite satisfied and use them for heating. So what is really true and what is not? Should I buy such a heater and where is it better to use it? Let's try to figure it out together.

Device and principle of operation

The main structural element of such a heater -halogen lampthat generates warm infrared radiation. It is like a halogen lamp for illumination and is a flask with a spiral. This helix (filament) is made of tungsten or carbon fiber. Spiral heating up to 2000 ⁰C is accompanied by the release of infrared waves of golden color, which transmit heat to the environment. With the help of a reflector, a directional heat flux is formed.

The design of the lamp provides a long service life at high temperatures of the spiral and greater energy efficiency, as well as quiet operation and instantaneous heating.

Rather compact dimensions and a variety of design of halogen heaters make it possible to place them on the ceiling or walls, or just put them on the floor.

Special features

Traditional heaters heat the air first, and infrared, on the contrary, first objects and objects. Waves penetrate the walls of the room, objects in the room and even in the human body. And the heated objects then give up their heat to the air in the room.

Another important feature of such heat sources is directional rather than diffuse heating. The infrared stream is focused with reflectors, and heating occurs locally. This is convenient in cases where it is not necessary to heat the entire room, but only need to heat a limited space.

The characteristics that you need to pay attention to when choosing a halogen device is its power and the recommended area for heating. The higher the power of the device, the larger the area it can heat.For example, a model with a power of 1.6 kW is able to cope with its task in a room of up to 16 square meters.

Floor models

The following devices are - outdoor options heaters with adjustable height rack. Equipped with automatic shutdown when overheating, when tilting or tipping over. Used as sources of heat and additional lighting.

disadvantages

The minus of the heaters is that the incandescent lamp shines very brightTherefore, for heating, for example, at night such a device is not suitable for everyone.

However, the main and most serious disadvantage of a halogen heater is that it emits mostly short and medium waves of the infrared spectrum, which have a negative effect. effects on the body person And this, in turn, limits their use and time of use.

A bit of physics! A halogen lamp emits about 50% of medium-infrared waves, 35% short and 15% long. Short waves tend to penetrate deep into human tissues and overheat too much. The physiological effect of the mid-wavelength range of infrared radiation on a person with prolonged directional heating is unsafe.

A reasonable question arises - where do they apply this type of heating equipment?

Initially, halogen lamps were developed for technological processes of heating and drying materials, since “hard” radiation has a high power. Therefore, their rational use in construction, during repairs, in order to dry wet or painted surfaces, for a brief warm-up of household and warehouse premises.

Heaters can be used as a source of heat in the street, however, not in a constant mode. Since energy is not used for heating the environment, but purposefully goes to the zone where people are located, these devices are widely used:

• in restaurants, bars, hotels, indoor and outdoor areas;
• in pavilions and under canopies;
• during various events, presentations and corporate events;
• in recreational areas and parks;
• in exhibition complexes.

So, we can conclude that halogen heaters, as devices that operate on the mid-wave and short-wavelength range, are prohibited for long-term home use. However, it can serve as an excellent source of heat and light as a street option or for short-term household use.
