Special features of the  Vitodens  100-W heat only gas boiler

The MatriX-Plus burner:  the heart of your heating system

Among the benefits of the MatriX-Plus burner are its efficient operation, quiet running and low emissions.  The special stainless steel MatriX surface is resistant to high temperatures, which ensures reliable performance and a long service life.  

Another technical innovation is the Lambda Pro fully automatic combustion controller. It automatically adapts to all gas types and ensures consistently clean and efficient combustion.

Stainless steel Inox-Radial:  efficient and durable

Stainless steel makes all the difference. The corrosion-resistant stainless steel Inox-Radial heat exchanger is at the heart of the Vitodens 100-W/111-W. It converts the consumed energy into heat very efficiently. In addition, the highly durable, high grade stainless steel ensures reliability.

Energy savings, convenience and security with ViCare

The new Vitodens with Viessmann One Base platform connects the heating system directly to the internet if required (for the Vitodens 100-W Heat Only this requires the addition of a separate Wifi modem).  Operating the heating system is very simple and intuitive with the ViCare app. It sets the course for digital services and is in direct contact with the local heating contractor.  

As an option (subject to an additional charge), ViCare can use the smartphone's GPS function to detect how far the user is from the heating system. If specified distances are exceeded, the room temperature is automatically reduced.  

ViCare thermostat for more convenience and efficiency

You can also expand the system with a digital ViCare thermostat to enjoy even more convenience and efficiency.
