The discomfort caused by an unbalanced system
Imagine a home where one room suffers from an irritating draft, while another lacks air to breathe. This is a very common situation when a rigid duct system is installed without flow regulating dampers. According to the laws of physics, air always takes the shortest path of least resistance. Therefore, rooms closest to the ventilation unit receive a massive, excess airflow, while distant bedrooms feel unpleasantly stuffy in the mornings.
This imbalance directly leads to increased noise and heat loss. Excessive air velocity in the nearest branches creates audible pipe hissing that disrupts your rest. Furthermore, when strong winds blow outside, open trunk lines without non-return valves can suffer from backdrafts, bringing freezing cold and street dust into your home even when the heat recovery unit is running on a minimal setting.
Perfectly balanced peace in every room
By integrating regulating dampers, the system becomes a perfectly obedient engineering whole. Each valve creates artificial resistance exactly where it is needed, forcing the fresh air to distribute evenly across all spaces in the house. The furthest bedroom receives exactly the same comfortable and quiet airflow as the living room closest to the unit. You forget about drafts and simply enjoy constant freshness.
Non-return valves act as invisible guards for your home. They ensure that the airflow moves in only one, correct direction. In winter, they instantly prevent cold air invasions into your pipes, while flow balancing allows the heat recovery unit to operate at much lower speeds, extending its lifespan and saving energy.
Proper system balancing with dampers ensures air is distributed evenly, reducing the load on your heat recovery unit and eliminating any aerodynamic noise – this is the key to absolute ventilation comfort.
