German Quality and Performance
In 1978, Viessmann opened its first first site outside Europe in Waterloo, Ontario. The fall of the Berlin Wall in 1989 opened up new markets – initially in the former East Germany and later in Eastern Europe. At the end of 1991, Dr. Hans Vießmann handed the company over to his son Dr. Martin Vießmann.
With its outstanding design and price/performance ratio, the Vitodens 100-W is the perfect mix of performance and value. Its compact design, zero clearance to combustibles and extremely quiet operation make the Vitodens 100-W an ideal choice even in the smallest spaces.
The Vitodens 100-W offers an integrated WiFi interface, which allows the system to connect directly to the internet allowing for seamless integration with the ViCare app for smartphone or tablet. Once connected, ViCare offers a range of homeowner tools, including remote operation of your boiler, DHW scheduling and temperature control, visualized fuel usage and cost savings, and the peace of mind that your home’s heating system is up and running, no matter where you are.
