Infrared Versus Radiant Heaters

In our own home we can now take advantage of this method and continuously produce comfortable temperatures with a radiation heating system. Here too, only solid and liquid objects are heated, which in turn transfer heat to the room. However, the air is a diatherm, that is, permeable to the heat rays produced. Therefore, the ambient air temperature Terrasverwarmer can be kept cooler, which is perceived as much more pleasant than when using convection heating. The wavelength used in radiation heating is in a range of 2 to 50 μm, which is completely safe. Infrared energy travels at the speed of light without heating the air it passes through, and is absorbed or reflected by the objects it hits.

In terms of cooking time, infrared ovens and conventional ovens do not differ that much. Most of the food you cook absorbs infrared energy, resulting in a faster cooking time. The moisture in the food you cook in an infrared oven absorbs infrared energy. When molecules vibrate at high speed while cooking, friction occurs.

Radiation heating uses simple radiation to heat the surfaces of objects. Unlike air-heating convection heating, radiation heating emits infrared radiation, which travels unhindered until it hits a solid object, which absorbs and warms up radiation. A good common example of this is the sun in practice: therefore, when it is very cold, you still feel the heat while the sun is shining on your face. In general, convection heaters are stronger than radiant heaters because of the way they heat the air and because electric heating elements often use fans.

Because not the air but the objects in a room are heated, only a small amount of energy is consumed during the air exchange required for hygienic reasons. Convection heating, on the other hand, must first reheat all air in the room to restore the required temperature. In this case, a significant part of the air is moved, which also leads to a continuous dust swirl. This puts a strain on the mucous membranes, which is a major drawback, especially for allergy sufferers and asthmatics, and counts towards the use of convection heating.

Infrared depends on conduction heating to transfer heat from the hottest outer surface to the inside of the part. The only way to increase the heating speed once an emitter style is chosen is to have a higher external surface temperature that conducts more energy into the protected areas of the part. If not checked, these temperatures can rise significantly and are representative of the black thermocouple shown in Figure 2. Temperature control is normally done by controlling the temperature of the part itself and not the air temperature.

The debate about convection versus radiation heating can be resolved by wondering where you are using the device, what you are trying to heat up and how long you will use it. Convection heaters slowly heat air in a room, while radiant heaters heat people and objects quickly. Whichever model you choose, you will be happy to know that both are equally energy efficient for their respective uses. To compare, when the emitter is 3,600 degrees F, the percentage of energy waves that would fall into the visible light spectrum would be less than 3 percent.

For example, the central heating system for gas boilers is a perfect example of a predominantly convection-based system. When you turn on your heating, the radiators warm up as the water circulating in the system warms up more. After about 15-20 minutes, you may feel the room warming up as the heat spreads from the radiator surface to the room. Make this luxurious convection heater part of your interior to immediately enjoy the style, warmth and comfort. The stove is designed with 1500 watts of power and has 2 heat configurations and a children’s safe. The advantages of obtaining radiation or convection heaters are even more pronounced compared to using a central heating system.

You can leave the window open on a winter day and still have the same heat-eater comfort as your infrared heater.

They use 100 percent of the heat they produce, which causes hardly any loss with heat transfer to zone heat at a low cost. This is because, unlike other additional heating devices, infrared heaters do not heat the air and instead emit infrared radiation that only heats the objects that touch radiation. The physics involved is similar to the way sunlight heats objects, which means that the heat from an infrared space heater can heat a natural feeling.

Heat radiation results in a much more comfortable room climate than convection heating. Underfloor heating does not circulate air and the room air is experienced as less dry. Due to radiant heat, there is also no mold, because condensation only takes place when the air cools down. That is why this heating system is very suitable for allergy sufferers. They heat the wall surfaces and objects in the room from which heat is transferred as heat radiation to the entire interior and is evenly distributed. Therefore, radiation heating and convection methods are based on two completely different physical processes.
