The NIBE DVC 10 is an energy-efficient ventilation unit for houses with natural ventilation, which ventilates the house at the same time as recovering energy. The ventilation unit does not require a duct system and is easy to install. The NIBE DVC 10 is suitable for combining with a heat pump. The NIBE DVC 10 has a built-in fan which works in two directions to create a good indoor climate. The heated indoor air is sucked out of the building, heating up the unit’s ceramic element. The fan then changes direction, and the NIBE DVC 10 draws in fresh air. The ceramic element then gives off its stored heat, which means that approx. 90 per cent of the energy that would otherwise go to waste can be recovered. The NIBE DVC 10 is perfect for use in older houses where the ventilation needs to be improved. Most units can be connected to a larger system through efficient, smart WiFi control.
