Residential Ventilation Unit with Heat Recovery


Ventilation systems with heat recovery offer users a high degree of living comfort thanks to temperature controlled and clean air. Heat recovery units are ideal for homes, for these owners who are looking for high performance and maximum comfort.


Residential ventilation unit with heat recovery.
Fresh filtered air and high energy savings 

The heat recovery ventilation unit is design not only to provide a good indoor air quality, but it is also designed to recover heat that would otherwise be lost throughout ventilation. These heat recovery ventilation systems are used in low energy homes to assist in the retention of heat.


High indoor air quality
The unit is designed to provide fresh filtered air into the home, while keeping a high thermal comfort.


Energy saving
Most of the energy from the exhausted air is used to precondition the incoming air, leading to lower heating requirements in the building.


Space saving
The compact ventilation unit can be installed over the DHW square tank or the Aquarea All-in-one Compact indoor unit for an space-saving solution.


Better user interface
The Residential ventilation unit and the Aquarea heat pump can be controlled with one single user-friendly controller.

The Residential ventilation unit with Heat recovery provides fresh filtered air into the house whilst retaining most of the energy that has been used in heating the house.
