Additional benefit: room-by-room ventilation
In many homes, fresh air means opening a window — and losing heated or cooled indoor air. Ecoviq can provide room-by-room ventilation whenever the heat pump or split AC is running, without a separate ventilation fan or ventilation machine.
Ventilation + energy recovery in one simple solution.
Estimate only. This calculator uses a simplified reference model of

Actual savings depend on climate, system type, airflow, operating hours, installation and local conditions.
Electricity defaults are indicative household values and can be edited by the user.
