Vitovent 100-D

Viessmann Vitovent 100‑D – Decentralised Mechanical Ventilation Unit
Quiet, energy‑efficient decentralised ventilation system with heat recovery up to 91%, delivering up to 46 m³/h, designed for flexible installation in external walls for both modernisation and new construction projects.

Features

High‑Efficiency Heat Recovery

Recovers up to 91% of heat from exhaust air Reduces heating energy losses Improves overall energy efficiency compared to window ventilation

Decentralised Ventilation Concept

Installed directly through the external wall No ductwork required Ideal for: Renovations Modern airtight homes Individual room ventilation Supports flexible system expansion

Alternating Operation Principle

Operates in pairs for continuous ventilation One unit supplies fresh air while the other extracts stale air Fans reverse direction approximately every 70 seconds Integrated ceramic heat storage: Stores heat from exhaust air Transfers it to incoming fresh air Ensures efficient heat recovery and constant air exchange

Energy Savings & Moisture Protection

Continuous ventilation reduces indoor humidity Prevents condensation and mould growth Protects building structure and improves comfort Eliminates need for frequent window opening

Flexible Airflow & Zoning Control

Allows individual air change control Supports division into ventilation zones Enables targeted airflow adjustment for each room

Summer Ventilation Mode

Airing mode enables fresh air intake without heat recovery Uses cool night air for passive cooling Improves indoor comfort during warmer months
