The definition of comfort

The importance of a radiant system for comfort

Comfort in the home is affected by many factors. It is dependent on our needs as individuals and our personal perception of comfort as the seasons change. UNI EN ISO 7730 sets out the parameters for indoor comfortand identifies ideal conditions as a perceived room temperature of approximately 20°C and a percentage humidity of 50-55%.

A radiant system operating at a surface temperature of 26-27°C triggers transfer by radiation, bringing the entire structure to a temperature in the region of 22-24°C. This temperature is not just found in certain points of the house but is evenly distributed across the entire floor area. This ideal distribution of temperature in each room ensures a high degree of comfort.

The body is enveloped in a warm "cocoon" and doesn‘t suffer the sensation of cold experienced in rooms fitted with traditional systems, such as radiators, or from turning one‘s back to a window or poorly insulated wall. The "warm cocoon" allows the body to tolerate a lower air temperature without experiencing discomfort.

Colder air is also less dry which is better for the respiratory system.

The cause of inflammation of the nasal mucous membranes, laryngitis and bronchitis is excessive heating of the air as a certain degree of moisture is necessary for the mucous membranes of the respiratory system - the first natural filter against external bodies - to work properly.

Air at an even temperature in a room prevents the generation of annoying air currents, the cause of airborne dust in radiator-heated environments.

These air currents are caused by expanding air molecules. When air molecules come into the vicinity of a radiator they heat up, increasing their volume. Since they are lighter they tend to rise, before cooling and falling back down again.
