Vitodens 300-W: Convenience of heating in its most efficient form
A new generation of heating systems. More efficiency, less emissions, easy operation. Future-proof, durable and digital. The Vitodens 300-W sets the standard for the future.
Easy to install, operate and maintain – this is the new generation of Viessmann wall-mounted gas boilers. The series of appliances presented at ISH Energy 2019 is a prime example of reliable and efficient space heating and hot water in the home, as well as exceptionally innovative design. Since then, the Vitodens 300-W wall-mounted boiler has been the winner of the iF Gold Design Award 2019.
Economy and smoothness: high level of efficiency with any gas mixture
Viessmann’s state-of-the-art gas condensing boilers are equipped with the patented Lambda Pro Plus® combustion control system. It adapts your instrument to changing operating conditions, such as fluctuations in gas quality or different types of gas. Automatic monitoring ensures a consistently high level of efficiency for your system. Your contractor will not have to reconfigure these boilers, and flue gas inspection intervals have been extended to three years. This saves time and money.
Equipment for the future
The technology that allows the use of mixtures of natural gas and hydrogen for heating buildings is already available and is available on the market in many thousands of cases. In principle, the latest generation of gas condensing boilers Vitodens 300 can already run on 20 percent hydrogen today. Therefore, house and apartment owners who choose these modern wall-mounted and compact appliances are ideally prepared for the future. Find out more about climate-neutral hydrogen heating.
