Infrared heater for work and living quarters: principle of operation and advantages of use

Various heating systems exist today. Heating with infrared heaters is a heating system that emits long beams from 780 nm to 1 mm long. They increase the temperature of another body, including a person, without the least danger to him.

Most of the heat from the sun enters our planet in the form of infrared radiation. Infrared radiation is the reason why we feel warmth from the sun, despite the fact that the sun is 150 million kilometers from the earth.

Benefits of infrared heaters

Unlike natural infrared radiation sources (eg sun, fire), the heaters in question generate radiation by technical means. They are increasingly being used as space heaters in residential or work areas.

For example, there are infrared emitters, which are technical devices designed to convert the maximum possible part of the energy supplied by it (electric current, gas) into heat and dissipating it with the help of radiant surface. There are also infrared heating films for installation in underfloor heating, wall heating or ceiling heating.

By installing infrared heating, you can drastically reduce your energy bills and CO2 emissions without losing efficiency and temperature levels.

Working elements of devices

The most common material used for electrical appliances is tungsten wire, which is coiled to provide a large heating surface area. Low temperature alternatives for tungsten are carbon or alloys of iron, chromium and aluminum. While carbon components are more volatile and difficult to manufacture, they heat up much faster than a comparable FeCrAl-based medium wave heater.

When light is undesirable or unnecessary in a heater, ceramic emitters are preferred. The heaters contain 8 meters of special alloy wire and radiate uniform heat over the entire surface of the heater, while ceramics absorbs radiation by 90%. Since absorption and emission are based on the same physical laws, ceramics are ideally suited as a material for such heaters.

Industrial heaters sometimes use a gold coating on a quartz tube that reflects radiation and directs it to the heated body. Consequently, the radiation incident on the body is doubled. Gold is used for its oxidation resistance and very high (approximately 95%) infrared reflectivity.

Differences between convector and infrared heating

Looking at overseas experience, most buildings in the UK are heated with radiators. Despite their name, they do not emit heat. Hot water flows through a radiator, which in turn heats up and heats up the air around it. This warm air then rises and is replaced by the colder air underneath. As this cycle repeats, convection currents are created that move around the room to warm it up.

An infrared space heater is very different in the following ways:

• Heating does not rely on air as a heat transfer medium;
• Infrared waves are generated directly by the panel;
• The heated air stream constantly circulates in the room;
• When the waves reach a solid object, it heats up, retaining the received heat for a long time.

As energy turns to heatwhen it comes into contact with solid objects, then empty rooms do not present a problem for the sensation of warmth. The features of such a heating system are:

• Infrared heaters will also provide optimal temperature within 30 seconds after being turned on;
• Since there are no moving parts, they do not generate noise and are therefore ideal for heating in bedrooms;
• The devices are compact and can be designed to provide another function, such as a bathroom mirror, which helps save space;
• Since infrared heaters heat solid objects in the home, such as walls, they prevent moisture from forming on these surfaces and prevent mold from spreading;
• Virtually maintenance-free;
• These heaters are emission-free (no fuel is burned). When used in combination with renewable energy sources, you get 100% clean green heat;
• The way these heaters heat a room is more efficient than conventional convection heaters, so they are more economical.

Areas of use

More and more companies are introducing infrared heating solutions, gradually replacing traditional heating systems. This is because heating panels are energy efficient, as they take very little time to warm up and they are also less exposed to cold air. If cold air enters a room with convection heating, the hot air will be removed very quickly and physical bodies will again rapidly lose heat.

In restaurants and bars

If you are sitting in the open area of ​​the bar, you can see the infrared heater in action: it glows red, and you can really feel the warmth. These are old infrared heaters, although nowadays you can feel similar warmth from a device that shouldn't be as bright. This means they are much safer in the work environment than older heaters.

You may have seen heating panels under umbrellas in the outside areas of restaurants. Heating panelswhich are recommended for heatingI commercial spaces work on the same basis, although they do not glow red and look much more attractive.

Infrared panels have an elegant appearance. They can be glass, mirrored, or printed with your favorite photo for a canvas effect. You can get very thin panels (2cm or less) and can be hung anywhere. All they need is access to the power grid, so there is no need to install additional piping. Some panels also offer dual functionality, for example they act as mirrors. We can observe them in restaurants using such panels and for recording menus.

For warehouses and greenhouses

If you need more powerful heaters, there is a choice of heaters up to 2 kW, so they can provide you with extra heat. These systems are ideal for large spaces such as warehouses, industrial greenhouses, etc.

In warehouses, the use of such heaters is the ideal solution today, mainly because they help reduce humidity. At the same time, a special sensor raises the temperature of any surface on which it falls. This can be very helpful if your business is dealing with perishable goods.

Conventional heaters heat the room with convection currents that continuously circulate with dust particles inside the room, however, these convection streams do not occur with infrared heating, so for people with asthma, infrared panels can be ideal decision.

One of the main advantages of infrared heating is that the panels are almost maintenance-free due to the lack of moving parts. And for adjustment, you only need to correctly set the program with an indication of the temperature regime you need.
