just a few years such as infrared heaters so popular today become a commodity, available to almost everyone.Produce these devices in many European countries, as well as in China and Russia.When buying a heater, of course, I want to see it did not break, and many years to come warm.We will try to find out where and how to choose the infrared heaters, building on their structural features.For this we consider in detail how to construct and how to operate these devices, as well as criteria for their selection.

design features and operation of the heater infrared type

These devices vary from convector r

adical - they are heated not the air, and objects in the room, inincluding floor and wall.In general, the infrared heater can be compared with the room the sun - its radiation, like sunlight, permeates the air, absolutely no warming it.But as soon as the beam reaches the object, the light impervious, that it immediately absorbs naturally hot gas.

Infrared waves are longer - they are perceived by our skin as the heat from the sun.We feel it, but can not ever see.And these rays warm us, regardless of wind and drafts - they are absolutely not a hindrance.Similarly, not afraid of drafts and heaters, infrared type, used in everyday life - because the wavelength of the radiation at a wavelength similar to the IR spectrum of the sun.

None convector can not heat a room instantly - because when his work is a constant movement of warm air up.That is primarily heated space near the ceiling, and we're at the bottom of something, and while air masses (warm and cold) mixed, passes a lot of time.That has to be cold all the time, waiting for a comfortable room temperature.

The principle of operation of the convector
air movement during convection.

In the case of infrared heaters everything else - the heat from them, we begin to feel immediately after turning on the device, but the heat is not felt throughout the room, and so on locally. Ie. Only in the place where the radiation.

Heating using infrared heater
principle of heating infrared heater.

Inside the device there are no particularly clever elements.In the steel case, on which a durable powder coating, reflector is made of aluminum.This reflector set the main structural element - the heater.There are four varieties of these elements: halogen, carbon, ceramic and tube (called the heating element).

Also each infrared heater has a thermostat to control the temperature and the sensor, switch off the device in case of overheating.If the device is intended for installation on the floor, it is compulsory also equipped with a rollover sensor.

Tips on choosing the type of infrared heater

Design - ceiling, wall or floor?

So, how to choose the infrared heaters for home and how performance will be preferable?It depends on the size of the room and on the conditions of use of the device.Let's start with what is specified, we need a stationary device, or the device is expected to move from room to room.Mobile heaters are smaller and have a little power, and are stationary wall, ceiling and baseboard.

In general, the most convenient type of ceiling devices are infrared heaters.They will not take too much space, and the range of the radiation from them is extensive.There are models mounted in the ceiling - recessed, and there are those that are attached to the normal ceiling special brackets - suspended.At this distance from the top surface of the body is about 5 centimeters.

Dispersion IR rays

Low-power and is not as effective heaters floor type meet on the way its radiation greater obstacles than the ceiling.If you choose one, it is best to stay on the model with carbon or tubular heating element.The ceramic heater is not so long, however is not very suitable.Halogen heating element that emits waves that can adversely affect the rights and all use is unacceptable, since for the normal operation of the device must be long-wave radiation.

heaters, attached to the wall should be on the floor some distance.If a family has kids, the height of the heater is made so that children do not reach the operating unit.If you need to put the heater under the window, choose a model with plinth performance - it will fit perfectly under the window opening.

little about the wavelength and temperature of heating

heating elements located inside the IR heaters can have different lengths and different waves emitted by the heating temperature.They are the following:

emitters emitting long (in the range of 5.6 to 100 micron) wavelength.Their operating temperature ranges from 100 to 600 degrees, they can be used in homes and offices, and industrial buildings, ceilings are not higher than three meters.However, plenty of heater in the apartment with a working temperature up to 120 degrees.

Medium wave (with a length of 2.5 to 5.6 microns) emitting heating elements, basking stronger - from 600 to 1000 degrees.In this ceiling the room should be 3 to 6 meters.This could be, for example, a private home or office building.

Short wave (from 0.74 to 2.5 microns) emitting heating elements operating at a temperature of 100 degrees.There are already required ceiling height - from 6 to 8 meters.These ceilings can be factory or factory floor.In addition, this type of heaters can be used on the street.At home, we do not recommend their use.

Choose the type of heating element

Decide how to select an infrared heater, it is necessary to bear in mind that they differ primarily by the shell into which is placed an element that emits waves.This sheath may be made of metal, ceramic or quartz.

Halogen heating element - represents a halogen lamp that emits in the infrared range.Inside the bulb is a filament made of tungsten or carbon.When heated, the thread is released infrared energy and its transfer tube lamps.All halogen lamps emit a golden light, which can irritate the eyes, to combat this, some manufacturers cover the lamp with a special compound.But the main disadvantage of this heater lies in the fact that the halogen heater emits waves, and they may have an adverse effect on humans.Therefore, in our opinion better to abandon the infrared heaters equipped with such a heating element.

Halogen infrared heater

Carbon heater element - is made in the form of a tube made of quartz.Inside it has created a vacuum in which the carbon (carbon) spiral.The advantages of such an element are very fast warm-up and the fact that its efficiency exceeds the efficiency at the heated metal plates.However, there are drawbacks: they are about two years, and consume too much power - from one to two and a half kilowatts.They also shine a light reddish, irritated eyes.Also, do not use them asthmatics and allergy sufferers.In short, this type of heater is suitable only for short-term work - a long time to use them is harmful.

heating element with a ceramic shell well-protected, so no lights in the process.And serves as an element of not less than three years, that's just the price of it is higher than that of quartz.But it is quite economical, and its power consumption range is from 50 to 2,000 watts.This difference is due to structural features.Despite the fact that such heaters do not heat up very quickly and cool down, they are often used in hospitals and in the saunas - because they are very strong.

Tubular (Micatermic) element of metal resembles the design element of the ceramics, but is more expensive.Work such heaters are good, they are very reliable and convenient in everyday life.If you do not have annoying little crackling at work, you can opt for a similar device.And he is cracking because the coefficients of thermal expansion of steel and aluminum spiral shell variety.Nothing wrong with that.Choosing this type of heater, check what characteristics a heating element, radiator casing, foil and insulator.

Questions to Ask When Buying an infrared heater:

  • deciding how to choose the infrared heater, first of all, you should inquire what has the thickness of anodizing layer on a plate, emitting infrared waves.If it will not have a thickness less than 25 microns, the prosperous operation for 20 years is ensured.If this layer is thinner, then after three years, have to say goodbye to the heater - burn.It is a pity that this option is visually check fails - when buying a device has to rely only on the honesty of the seller.
  • Material heating element is also important.If this is black metal, then where it is wet (eg in the bathroom or sauna), a heater is not available.If you use stainless steel, it is much better.
  • radiator foil thickness should be not less than 120 microns.If the foil is thin, it is instead to heat the room, the beams will be wasted to heat ceiling.Check the thickness of the foil is simple - to put pressure on her ballpoint pen refill.If crumple foil or holes, so - it is not very high quality, no thicker than 100 microns.And at 120 micron hole do not succeed.

What power is optimal for IR heater

On 10 square meters of the room, as a rule, required power 10 kW.But it is better to acquire a heater having a power supply (especially if the other heat source is not provided).It is necessary to consider the heat loss through walls, floors and windows.When the heater is used as an addition to the existing heating system, the power is calculated in relation to the conditions of his work.It is also necessary to bear in mind the heat loss.

In stores you can find heaters with capacity of only 300 watts.They are very convenient to use, where you need to quickly and briefly heat the room, such as a basement or garage.Such devices will not cause any harm, so they may work in close proximity to people.

If you need to select the infrared heaters to give aware that summer houses do not need much heating temperature - will be sufficient to raise the temperature in it is only a few degrees.Therefore, it is possible to choose a heater at the rate of 60-80 watts of power per square meter.If it is very cold, these figures have to adjust.

on insulator

to the heater did not warm above 95 degrees, it has an insulator.They come in various types, of which the best and safest considered basalt insulator.Especially good if it has no additives.After all, these supplements may be harmful to human health - they are a source of heat in the toxic formaldehyde.The best option is when the insulator is allowed to use in the food industry - it should be noted in the hygienic certificate (it must show the seller).

should look like the heater

The enclosure must be made of a material of good quality - it will serve as a heater for a long time their owners.Previously, the material for its production was only steel, but now appeared housing made of aluminum.They are more beautiful and modern look, but the steel body, of course, more reliable.Looking around the device, look at the body from the inside - it is not usually paint, which is quite natural.But the presence of traces of rust should alert you.This means that rust and gradually act on the outside, not only ugly but also shorten device life.

Select manufacturer

Usually we want to buy goods such brand that has manifested itself in the most favorable light.Of course, you can buy goods from Europe, only it will cost dearly.Furthermore, we must bear in mind that almost all large companies from Europe have factories in China, where the cheapest labor.Gradually they begin to take and accessories there.Due to this, and there is a loss of quality.Therefore, when choosing products, pay attention to the country of manufacture.

Options

Not be superfluous if the heater is:

  • integrated thermostat allows to maintain a constant temperature;
  • temperature sensors;
  • desktop desirable sensor rollover protection;
  • remote control, ceiling models are generally supplied to them, while others depend on the availability of the model.

How to use infrared heater

easiest to care for ceiling-mounted units - periodically brush away the dust and everything.As for the models of wall and floor type, the main rule - no cover them from above.Being their front covers no less than a meter away from the outlet (which must be earthed), and any items in the room.Where humidity is high, use the device, degree of protection which is not less than IP24.

Infrared radiation for humans is not harmful.You can say it even improves health.That's just under the direct rays should not be a long time - you can get, like the sun, heat stroke.And again, if the warming room heater capacity of 150 watts per square meter, then you can not only weaken the immune system, but also damage the structure of protein molecules.It is best to use devices with a capacity of 60 to 100 watts per square meter.

heaters operating on short wave, do not buy - the waves can penetrate into the body.Long waves are not dangerous, but such heaters should be strictly regulate the height, since the radiation of these waves are so intense, the smaller the distance to the area of ​​exposure.Be sure to watch out for their well-being when using heaters Eek.If you feel uneasy, better reduce the radiation power.The rule is: several infrared heaters with a low power better, safer and more efficient than a single but powerful heater.
