The Vitodens 200-W wall-mounted gas condensing boiler is ideal for use in apartment buildings, commercial spaces, and public institutions. Designed and manufactured by Viessmann, this boiler is the only one of its kind in the world. As a modular cascade system, it is not only cost-effective but also offers space-saving solutions. Cascades with rated heating outputs ranging from two at 49 kW to six at 99 kW can be combined, even in spaces with low ceilings (as low as 1.9 meters).
