Heat in the most efficient way. With the Vitodens 300-W gas condensing heater.
The Vitodens 300‑W is a premium wall‑mounted gas condensing boiler designed for high efficiency, maximum comfort, and future‑ready operation. It combines Viessmann’s proven heating technology with modern digital control, intuitive operation, and hydrogen readiness, making it ideal for both new installations and modernisation projects.
With advanced combustion control, smart connectivity, and hybrid readiness, the Vitodens 300‑W offers reliable heating today while remaining adaptable to tomorrow’s energy systems.
Centralised control via the 7‑inch colour touchscreen, offering intuitive navigation and clear system information.
Remote operation, monitoring, and optimisation through the ViCare app, including access to the Energy Cockpit.
Built‑in Wi‑Fi allows direct internet connection without additional hardware.
Designed for seamless integration into hybrid heating systems, enabling combination with renewable heat sources.
Both devices stand for modern and efficient gas condensing technology. The Vitodens 300-W is the premium device and offers a wider modulation range: it can reduce its power to 1.9 kW. This ensures particularly smooth and efficient operation, especially when heat demand is low. In addition, it has a large 7-inch color touch display for high ease of use.
The Vitodens 200-W is functionally simpler and usually has a black and white display.
Yes. The Vitodens 300-W is hybrid-capable and designed for later combination with degenerative components. It can be supplemented with a heat pump to form a hybrid system or combined with solar thermal energy. In this way, gas consumption can be gradually reduced, and the heating system can be expanded in a future-proof way.
Lambda Pro Plus automatically adapts combustion to different gas qualities, ensuring high efficiency, low emissions, and reliable operation.
Yes. The Energy Cockpit provides clear visualization of energy production and consumption via the control unit or ViCare app.
