Red Dot
The OSA condensing gas boiler combines aesthetics and function in an independent way. It obtains its design appeal from the combination of different materials: the smooth front is in acrylic glass, while the sides are in carbon steel. The front is available in six different colours. The OSA condensing boiler, with all its connections concealed and merely 18 cm deep, is laid out for comfortable operation via wired interface or Wi-Fi with a dedicated app for smartphone or tablet. The device also includes indoor and outdoor temperature sensors, thus enabling energy-efficient heating.

Statement by the jury

»With its minimalist design, the OSA condensing boiler can be integrated into virtually any room. A refined detail is the circumferential edge structuring that contrasts the front and side while highlighting the different materials.«
