It is important to know

The key is that it is a built-in heat recovery unit, not a fan that you move between rooms as needed. Therefore, before purchasing, check whether you are looking for this type of device; the available data cannot reliably assess the suitability for the size of an individual room.

• The built-in design means that choosing the location of use is important even before purchase, as the device is not intended to be moved around.

Answers to frequently asked questions

Is it possible to determine from the available data how large a space a heat recovery unit is suitable for?
