It is a device designed for forced ventilation with heat recovery. As a standard, it includes at least fresh air supply and exhaust fans, a heat recovery exchanger, supply and exhaust air filters and a smart control with internet connection.

Heat recovery is basically the recovery of heat from the exhaust air. Both warm exhaust air from the house and fresh outdoor air are fed into the heat recovery exchanger inside the air handling unit. They are perfectly separated from each other by a set of channels in the plastic heat exchanger, so that odours and pollutants from the exhaust air do not penetrate into the fresh air. At the same time, the supply air is preheated by the exhaust air through the walls of the ducts. This significantly reduces heating costs.

Of course you can open the windows. However, this denies the principle and the main benefit of heat recovery - getting fresh air without opening the windows and thus saving heat that you would otherwise "expel" outside. We therefore recommend that you reduce this ventilation option in winter.

It depends on the chosen unit and many other factors. If the unit is installed correctly (recommended by the designer), then the noise level is almost zero. Usually nothing is heard because the units are placed in the technical room, closet, attic, etc. ATREA air handling units are one of the quietest on the market due to the sophisticated shell design!

In passive and low-energy construction, the installation of heat recovery ventilation is a hygienic standard. The heat saving benefit of heat recovery is directly proportional to its consumption. It is therefore noticeable in conventional construction. But in general, for healthy ventilation, where the fresh air is free of pollen, allergens, etc., installation is always suitable.

The units are usually installed in the technical room. But there are more options, for example in attics, basements, dressing rooms, lower ceilings and partitions.

No, this is a common misconception. Heat recovery is the recovery of heat from waste air. So there must be another primary heat source in the house.
