Free added value

Free added value through energy gain

With the Regel-air® FFL ventilation system, the air is directed through the window rebate in a controlled manner.

Between the time the fresh air enters the system and when it flows into the room, it is pre-heated by more than 10 °C in the window rebate when outside temperatures are low. The air enters the room interior in the upper area of the window and mixes directly with the warm air in the room.

This effect makes a significant contribution to improving the energy balance of home ventilation with Regel-air®, but has not yet been taken into account in the cost comparison under 2 c.).
