Radiant heat vs. convection heat
Thermodynamics and quantum mechanics
Radiant and convection heating methods are based on two completely different physical processes. A convection heater heats only the air of the room to be heated, while a radiant heater warms the outer wall and the objects in a room. Therefore, thermodynamics are in action in the case of convection heating, while quantum mechanics are at work with radiant heating. The heat radiation results in a much more comfortable room climate than is the case with convection heating. The radiant heating does not circulate the air and the room air is perceived as less dry. In addition, because of the radiant heat there is no mould formation, as condensation only takes place when air cools down. For this reason, this heating system is very suitable for allergy sufferers.
Make use of the sun
Radiant heat works like the sun’s rays
We know radiant heat from everyday life thanks to solar radiation, which heats up the objects that it strikes. In our own home, we can now profit from this method and continually produce comfortable temperatures with a radiant heating system. Here, too, only solid and liquid objects are heated, which in turn transfer the heat to the room. The air, however, is diatherm, that is, permeable to the heat rays that are produced. Thus, the temperature of the room air can be kept cooler, which is perceived as much more pleasant than when using convection heating. The infrared rays used in the radiant heat are electromagnetic waves. The wavelength used in the radiant heating is in a range of 2 to 50 μm, which is completely safe.
Low air exchange rate
Energy savings through radiant heating
The use of an efficient radiation heater can save energy in several ways. Since not the air but the objects are heated in a room, only a small amount of energy is consumed during air exchange required for hygiene reasons. Convection heating, on the other hand, must first heat up all the air in the room again in order to restore the required temperature. In this case, a considerable portion of the air is moved, which also leads to a continuous dust swirling. This places a burden on the mucous membranes, which is a major disadvantage, especially for allergy sufferers and asthmatics, and counts against using of convection heating. The lower air exchange rate due to the dormant air of the radiant heat is not only allergy-friendly but also ensures further energy savings. In order to heat the air, a temperature difference between the room air and the heating element is necessary in a conventional convection heating system. Radiant heating, on the other hand, follows Stefan Boltzmann’s law and is proportional to the fourth power with respect to absolute temperature.
Radiant heats vs. convection heat – the differences
While conventional heaters, also referred to as convection heaters, deliver part of their heat energy transferred to the ambient air to increase the room temperature, Energy-com skirting board heating panels uses radiant heat. They heat the wall surfaces and objects of the room from where the heat is transferred as heat radiation into the entire interior and distributed evenly. Thus, radiation and convection heating methods are based on two completely different physical processes. Convection heat works according to the principle of thermodynamics, radiant heat according to the principle of quantum mechanics.
Radiant heating offers many advantages
Our heating panels work like other radiant heaters and can be compared with radiant heat by solar radiation, which heats the objects that are hit by the sun’s rays. The heating elements in our skirting board heating panels are heated electrically or by water depending on the chosen model, and produce a much more comfortable room climate than is possible with convection heat. The radiant heat generated by skirting board heating does not develop air circulation and creates room air that is perceived as less dry. No condensation is produced, which minimises the risk of mould formation and the walls can’t cool down. For allergy sufferers and asthmatics, a heating system based on the principle of radiant heat is the best choice!
Radiant heat helps to save energy
In contrast to convection heat, radiant heat also offers the advantage of providing even heat distribution in the room and not creating cold zones, which are very common with conventional heaters. The use of a radiant heater can save energy in several ways. Since not the air but rather the walls and objects in the room are heated, no renewed energy consumption is necessary for air exchange in order to heat the fresh air again. Convection heating, on the other hand, must heat all the air in the room again in order to reach the desired temperature again. In this case, a considerable proportion of the air is circulated, resulting in dust swirling. The lower air exchange rate, because the air is dormant with radiant heat, also ensures further energy savings.
