Controlled mechanical ventilation ensures a comfortable ambience and protects the fabric of the building In recent years, more stringent building regulations have led to sustainable energy savings, particularly in the construction of new houses and apartments. For example, in existing housing, the annual heat demand for a detached house is approx. 200 kWh/m². For a comparable new house, built in line with the new 2014 Energy Savings Ordinance (EnEV [Germany]), this annual heat demand is only around a quarter of that figure. Use of new building and insulating materials results in an airtight...

Controlled mechanical ventilation for consistently sound room air quality An adequate air change rate is essential for health and wellbeing, as well for protecting the fabric of the building. The answer is a mechanical ventilation system: It provides the air change rate required and regulates humidity levels in the interior. Such a system prevents mould growth and ensures the controlled replacement of stale indoor air with fresh, filtered outdoor air, thereby providing a comfortable ambience for residents and protection for the fabric of the building. Controlled mechanical ventilation...

Centralised ventilation in new build Many modern buildings are built with mechanical ventilation systems already installed. On the one hand, this requires a high level of energy insulation in order to regulate indoor air humidity as effectively and reliably as possible. On the other, it is regarded as a comfort feature for well equipped apartments or buildings. Mechanical ventilation in detached houses The installation of mechanical ventilation systems in new detached houses is already standard, especially in low energy and passive houses. Consequently, no heat is lost through accidental...

Modernisation project

Decentralised ventilation for existing buildings and modernisation projects The modernisation of energy systems in existing buildings is constantly being driven by rising energy costs in the housing industry. Old housing stock is being modernised comprehensively and now offers its residents such comforts as new, energy efficient windows and doors, wall insulation or a new heating system with convenient domestic hot water provision. Risks associated with modernisation Modernisation also results in older apartments being so airtight that no adequate fresh air change can take place. The...

Outstanding quality Reliable, durable technology – it's essential Viessmann mechanical ventilation systems are characterised by their innovative technology. They are durable, reliable and operate particularly quietly. With different equipment levels, they can be employed flexibly in the widest range of applications imaginable, no matter whether in a new building or the modernisation of an existing building. Overview of technology and functions Temperature curve in the corner of a room – this is where condensate CO2 and humidity control Air is considered to be fresh when the CO2 concentration...

Cross-countercurrent heat exchanger in the Vitovent 300-W Regular filter changes are required to ensure that everything runs smoothly. The active monitoring system indicates the need for replacement in good time. Just one unit for supply and extract air In order to ensure continuous operation, the Vitovent 200-D decentralised ventilation unit is equipped with two integral fans – one for supply air and one for extract air. Heat is recovered by means of a cross-countercurrent heat exchanger. This makes the Vitovent 200-D a complete ventilation system with heat recovery, which can be used for...

Mechanical ventilation system Viessmann supplies the Vitovent 300-W mechanical ventilation system for a healthy interior climate Enclosed spaces need to be ventilated regularly by opening windows. However, ventilation is not particularly reliable in most cases: Excessive ventilation results in the loss of expensive heating energy; too little, and humidity is not removed adequately, making indoor air unpleasant. The Vitovent 300 mechanical ventilation system changes air continuously for a pleasant and healthy indoor climate, removing odours and noxious substances. Prevent mould, protect the...
