3. FOR THE USER
3.1 Definitions
3.1.1 Balanced ventilation with heat recovery
The most healthy and energy-efficient form of ventilation is balanced ventilation. A balanced ventilation
system is one that extracts contaminated air from kitchen, bathroom, toilet(s) and, where necessary,
also the utility room, and supplies the same volume of fresh air to the living room and bedrooms. Gaps
under the doors ensure a good through-flow in the dwelling. The air circulation is literally in balance.
Ensure these gaps are never obstructed by draught excluders or deep-pile carpet, for example.
The system will then no longer function (optimally).
Besides ensuring a healthy balance between incoming and outgoing air, the Xcell 350V EC BP also
transfers heat from extracted air to the fresh, usually colder, outside air that it supplies. In this way,
roughly 95% of the extracted heat is recovered, ensuring the air remains at room temperature.
Furthermore, draughts will be a thing of the past.
3.1.2 Bypass
The bypass ensures heat transfer between extracted and supplied air is (temporarily) deactivated. This
means that colder outside air is not preheated prior to entering the dwelling.
