Vitovent 300-F central mechanical ventilation system together with a Vitocal compact heat pump

Mechanical ventilation unit plus heat pump – the perfect system combination for new build projects

Together with an air source or ground source heat pump, the  Vitovent 300-F mechanical ventilation unit combines the benefits of an integral appliance with the flexibility of Viessmann heat pumps. The heat pumps that can be combined with this ventilation system offer a heating output of between 3.0 and 10.6  kW. The system as a whole can be used for interiors with up to 210  m2.

All functions delivered from the smallest of footprints

This system combination is particularly suitable for new build projects, since all functions, such as ventilation, heating/cooling and domestic hot water heating, can be implemented in the smallest of spaces. The  Vitovent 300-F can be installed to the right or left of the heat pump, thereby forming a harmonious unit with a small footprint.

*  Vitovent 300-F can be combined with all heat pumps equipped with the Vitotronic  200, type WO1C.

High operating convenience

The  Vitovent 300-F ventilation module is connected directly to the heat pump. All settings can be made from either the heat pump's Vitotronic  200 control unit (WO1C), a common remote control unit or the Vitotrol app. At the same time, heat pump operation and ventilation are automatically matched to each other.

Up to 98  percent heat recovery

The  Vitovent 300-F recovers up to 98  percent of the latent heat in extract air, using it to heat the incoming outdoor air.

Air tempering in passive houses

The combination of a  Vitovent 300-F and heat pump can be used very effectively in passive houses for air tempering. By and large it makes a hydraulic distribution system superfluous. A reheating coil with an output of up to 1.5  kW is integrated for this purpose. In addition, an optional heating water buffer cylinder with a capacity of 25  litres is integrated into the  Vitovent 300-F.

Quick installation with flat duct system

A flat plastic duct system makes routing in unfinished buildings particularly easy. From air distribution boxes with integral silencers, the supply and extract air vents are connected individually via a flexible flat plastic duct. The smooth internal walls of the flat plastic ducts are antibacterial and antistatic.
