It is undeniable to say that comfort in our living environment, whether at work or at home, is important, particularly in winter. To create a pleasant environment in cold weather, it must be warmed to compensate for natural the loss of heat that will take place between our room and the outside.

To do this, there are several heating methods. The three most common in the market are:

Convection: Natural and totally silent, convection occurs when a hot body comes into contact with the surrounding air and warms it up. We typically call these units convectors.

Forced air: A well-known variant of convection is that of forced air. By this method the heater boosts its convection with a fan. This allows it to quickly push hot air into the room to meet a pressing need for heat. We typically name these types of units fan-forced heaters.

Radiant: Unlike convection which heats the ambient air in a space, this method warms the materials in the room (sofa, table, floor, etc.) through infrared wave transfers. By heating objects, radiant heaters create a feeling of enveloping heat, uniform and silent as the effect of the sun’s rays.


Radiant heat transfer is a natural phenomenon because all bodies emit infrared radiant waves. This applies to both your office chair as well as your dinner table. But how does radiant heat work?

To understand it better, it is necessary to divide it into two different methods of energy transfer; direct and diffused:

Direct: Heat transfer that is transmitted directly from the heating element onto the person or object. This provides an immediate sense of comfort.


Diffused: Heat transfer produced by the exchange with the environment in which the person is located, such as the wall, floor, furniture, etc. These objects, in turn, partially redistribute the direct radiant heat waves received from the emissive element. Diffused radiant heat thus contributes to the creation of a homogeneous atmosphere.
If we want to illustrate these two methods, take the example of the sun and a house. The direct radiant heat would be represented by the rays of the sun that we feel when sitting next to the window. In return, the diffused radiant heat would be created by the walls of the room heated by these same rays creating a pleasant atmosphere.

Diffused and direct radiant heat: For a radiant heater to provide the greatest possible comfort, it is preferable that it can offer the user both direct and diffused radiant heat.


 One of the great benefits of radiant heat is its ability to create a homogenous environment.

Indeed, as illustrated in the opposite figure, we perceive that the variation of temperature between the ceiling and the floor varies very little. This is due to the combined effect of direct and diffused heat distributed by the heater. This homogeneity in temperature creates an enveloping and comfortable environment around the user.



In order for radiant wall heaters to truly offer an enveloping comfort, it is important to avoid placing objects in front of it, such as furniture, so as not to interfere with its direct radiant heat transfer.

Radiant wall units such as those of our Opera line are ideal for rooms with large windows. The reason is simple. Imagine being outside in the middle of winter. If placed in contact with the sun's rays, you will feel its warmth and be comfortable. Move to the shade and you will probably be cold. While the cold winter air is the same, access to the sun's rays just gives that feeling of comfort. The same effect is produced in your living room.

The radiant wall units are also ideal for rooms with cathedral ceilings. Indeed, since these types of ceilings increase the volume of air in a room, it is more difficult for a convection heater to offer the same feeling of comfort. Unaffected by this increase of air volume, radiant heaters will bring you the same degree of comfort as if the room had a standard ceiling.

Finally, for the user to fully enjoy the benefits of radiant heat, the unit should be installed close to the places we occupy. For example, in a living room, the unit could be installed near the sofa where the person will be seated. Thus, the person will truly benefit from the direct radiant heat emitted by the unit as well as the diffused retransferred by the furniture.


As we have explained, radiant heaters deliver heat through a natural method operated by any hot object, most notably the sun. When used in our living spaces, this heating method offers a real feeling of comfort and homogeneous comfort. Finally, since radiant units also create convection they truly are a fantastic choice to keep you warm in winter!
