High Efficiency, Lower Fuel Bills
The Vitodens 100‑W runs at 95% AFUE and modulates over a 10:1 range to match real‑world loads. That means fewer on/off cycles, quieter operation, and less wasted energy throughout the heating season.
Stainless Steel Heat Exchanger
At the core is Viessmann’s Inox‑Radial stainless‑steel heat exchanger, built to resist corrosion in condensing operation and deliver steady efficiency year after year.
Compact, Wall‑Hung Footprint
A slim 17.7‑inch‑wide cabinet mounts on the wall to free up floor space. Front‑access service points and bottom‑entry piping help speed up installation and maintenance.
Flexible Fuel & Venting
Switch between natural gas and LP in software—no orifice swap needed. Choose 80/125 mm concentric or 3" two‑pipe venting to work around longer runs and tricky retrofit layouts.
Smartphone Control With ViCare
Built‑in WiFi connects to Viessmann’s ViCare app so you can view temperatures, set schedules, and get alerts from virtually anywhere.
