Does the Espaciel Reflector help to heat the room using sunlight?

In this article, we look at the heat gain from daylight redirection.

Yes, the Daylighting Reflector can help heat a room thanks to the sun. There are two operating configurations for the Espaciel Reflector. 

Overcast 

On an overcast, sunless day, light is diffused. The sky delivers around 1000 to 2000 lux. That's a flux of 10 to 20 Watt / m2. Natural light therefore contributes little to heating. The reflector's thermal gain is therefore limited. For example, for a surface area of 50 x 120 cm, i.e. 0.6 m2, the power returned by the reflector is 5 to 11 watts.   

Sun 

Direct sunlight is very intense. The sun provides between 20,000 and 100,000 lux. That's a flux of 200 to 1000 Watt / m2. Natural light makes a major contribution to heating. The Reflector's thermal gain is therefore significant. It therefore integrates a bioclimatic logic. For example, for a surface area of 50 x 120 cm, i.e. 0.6 m2, the power returned by the Reflector is 100 to 500 Watt.

A titre de comparaison la puissance installée usuelle pour le chauffage d'une maison est de 30 Watt / m2 habitable.   

Même au soleil le Réflecteur ne suffit pas à chauffer la maison à lui  seul. Il apporte toutefois une puissance significative. Lorsque le  soleil est présent, un Réflecteur Espaciel permet de chauffer une pièce  de 15 m2.

Which reflector to choose for room heating?

The most effective reflectors for heating a room are those that reflect the sun's rays back into the home, contributing to the bioclimatic contribution of the house.

- The Garden Reflector: 0 to 5 m from the window or French window

- The Motorized Reflector: 0 to 10 m from the window or French window

- The Intelligent Reflector : From 0 to 20 m from the window or French window
