When approaching an electric heating system, it is inevitable to ask yourself a series of questions: "Which heating system is right for me?" Among the available options, which one will weigh the least on your bill? And "how can I get a good level of thermal comfort?"
First of all, it is necessary to understand the differences between the various electric heating appliances, in order to understand what advantages each of them can offer you and which is the most suitable for your needs.
Let's start with a simple question: what is heat?
Heat is a transfer of energy, and its diffusion modes are basically three:
1 - Thermal conduction: heat is transmitted through contact between two bodies (eg heat that is transmitted from the tip of a lit poker to its handle).
2 - Thermal convection: it is the natural phenomenon whereby a hot fluid tends to rise and a cold fluid to descend, therefore the air heated by the radiator rises while the cold air descends to the ground (e.g. water from a kettle heats evenly, even though it is only at the bottom in contact with the stove).
3 - Radiation: consists in the contactless propagation of thermal energy in the form of electromagnetic waves (eg the warmth emitted by a stove that spreads throughout the environment).
Knowing how to distinguish the different ways in which heat is propagated is essential in identifying the heating system that can meet your thermal comfort requirements.
Now let's see how to distinguish the different electric heating appliances, in order to avoid confusion; in fact, the words "convector", "radiator" and "radiant panel" are often used as synonyms, although they indicate very different appliances:
Convector or convector = heat obtained by thermal convection (air heated by a resistance).
Radiant panel = heat emitted by infrared rays through a perforated grid.
Radiator = a heating body + diffusion of heat by radiation.
But let's see in detail how they work:
1- THE ELECTRIC CONVECTOR The convector is the oldest and most basic model available on the market and its technology is based on the phenomenon of natural convection: the hot air emitted by the appliance rises while the cold one descends.
It heats the ambient air through an electrical resistance. Cold room air, heavier than hot air, passes through a grille in the lower part of the unit, is heated by the resistance and, subsequently, comes out of another grille located in the upper part of the convector. This process takes place very quickly, offering the advantage of a heat spread quickly throughout the environment.
2- THE RADIANT PANEL The operation of the IR radiant panels is based on the generation and transmission of heat by radiation through infrared rays. The effect you will get is similar to the heat that is felt when passing from a shaded area to one illuminated by the sun. They are produced by an electrical resistance that usually heats an aluminum plate, as it is the most suitable material for rapid thermal propagation.
The panels do not produce annoying noises and spread heat evenly throughout the room, avoiding that a part is exposed to partial overheating or cooling as happens with classic radiators.
3 - THE ELECTRIC RADIATOR Electric radiators work by combining a convection and a radiation resistance, thus obtaining a rapidly diffused heat with lower consumption than the models mentioned above. The desired temperature is reached through the convection principle, and is then maintained through the radiant panel placed on the front of the appliance; in this way, when the heat in the environment is stable, consumption is reduced thanks to the convective resistance which switches off giving way to the radiant one.
