aRheat – simple ventilation system with heat recovery of up to 90%
Air recovery is one of the key elements of modern living today, especially in spaces where moisture often accumulates, such as bathrooms, utility rooms, and smaller living areas. The wall-mounted heat recovery unit aRheat is the ideal solution for anyone looking for quiet, reliable, and energy-efficient ventilation with heat recovery. With up to 90% recovery efficiency, it allows for significant savings on heating while ensuring a constant supply of fresh air.
Main advantages of the aRheat heat recovery unit
-
Heat recovery of up to 90%
Thanks to the ceramic heat exchanger, most of the heat from the exhaust air is transferred back to the fresh air, enabling high energy efficiency. -
Quiet operation
The operating noise level ranges from 13 to a maximum of 30 dB, which is nearly inaudible – perfect for bedrooms, bathrooms, and other sensitive areas. -
Easy installation
The telescopic duct allows installation through walls with a thickness of 270 to 500 mm. The device is already equipped with a cable and plug for quick connection. -
Low power consumption
The device consumes only between 2.5 and 4 W of energy, making it one of the most energy-efficient ventilation systems on the market. -
Remote control
Controlled with the included remote control, which also allows synchronization of multiple units at the same time.
How does the aRheat heat recovery ventilation system work?
The operation of the heat recovery unit is based on an alternating mode – every 65 seconds, it changes the direction of airflow. During exhaust, the heat from the room heats the ceramic element, and during intake, this heat is transferred to the fresh air coming from outside. This way, we obtain fresh, yet heated air without heat loss.
