The compact Vitovent 300-W central mechanical ventilation system requires very little space and can be installed above the washing machine, for example.

Vitovent  300-W mechanical ventilation system with heat recovery

Quiet, compact and easy to integrate into a domestic energy system: these are the strengths of the new  Vitovent 300-W mechanical ventilation system. When combined directly with a Vitocal heat pump, it can be conveniently controlled using the ViCare app and a smartphone. The system's internet connection means that trade partners can check that it is functioning correctly via a web browser using the ViGuide app. The  Vitovent 300-W can also be installed independently of this as a standalone system – in the loft, for example.

The special features of the Vitovent 300-W

The central system ventilates with almost no energy loss. It also works extremely energy efficiently. During colder months, the powerful heat exchanger utilises up to 92  percent (at 400  m3/h) and 91  percent (at 325  m3/h) of the latent heat in the extract air to preheat the inrushing fresh air. The integral electric preheating coil ensures continuous frost-free operation even at low outside temperatures.

During the warmer months, the heat exchanger of the  Vitovent 300-W can be bypassed completely via the integral automatic bypass damper. This temperature controlled circuit allows cool outdoor air to enter the interior at night, thereby ensuring a pleasantly fresh environment.

A filtration system featuring an effective optional pollen filter cleans the supply air of allergens and harmful substances. This significantly reduces the growth and spread of mites and mildew, thereby creating an irritant-free indoor environment.

One of the main causes of mould growth is humid indoor air. Mould can harm the health of residents and causes permanent damage to the fabric of the building.
