Heat recovery ventilation of the WALLER series is designed to offer high efficiency with low energy consumption, making it an ideal solution for ventilation of indoor spaces, improving comfort and reducing operating costs.

The heat recovery It is a process that allows the thermal energy present in the exhaust air to be reused, that is, the air already used inside a building, before it is expelled. This process occurs thanks to a device called heat recovery unit, which transfers heat from the outgoing air to the incoming air, thus improving the energy efficiency of the home.

How Does Heat Recovery Work?

The heat recovery unit is equipped with a exchanger which allows the passage of heat between two air flows, without mixing them. During the process:

The exhausted air is expelled from the building and passes through the exchanger, where it gives off some of its heat.
Fresh air from outside enters and is heated by the recovered heat, thus reducing the energy requirement needed to heat or cool the internal environment.
This mechanism allows for maintain a more constant internal temperature, reducing temperature fluctuations and improving comfort.

Heat Recovery Benefits

Energy efficiency: Significantly reduces energy consumption for heating and cooling, as the incoming air is already pre-heated or pre-cooled.
Living Comfort: By maintaining a constant temperature, the comfort of internal spaces is increased, improving air quality and reducing the sensation of excessive cold or heat.
