Compact and efficient wall mounted gas condensing boilers with a very attractive price/performance ratio

As a large-scale manufacturer with many years of experience in the production of wall mounted boilers, we know what matters. Viessmann product quality is something you can rely on, and the attractively priced Vitodens 100-W (with integral 46  litre stainless steel loading cylinder) are no exception. Viessmann wall mounted boilers are well known for innovative technology and performance, but their reliability and durability are renowned.

Thanks to advanced assemblies, this wall mounted gas condensing boiler is extremely compact and can be installed even in small recesses. No side service clearances are required, since all the connections are easily accessible from the front. This makes Vitodens wall mounted boilers ideal for modernisation of apartments or detached houses.

Equipped for the future

The technology that enables the use of natural gas/hydrogen blends for heating buildings is already available and on the market in many thousands of cases. In principle, the gas condensing boilers of the latest Vitodens  100 generation can already be operated with 20 percent hydrogen today. Home and apartment owners who opt for these modern wall mounted and compact appliances are therefore ideally equipped for the future.  Learn more about  climate-neutral heating with hydrogen.

Special features of the  Vitodens  100-W.

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. 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 Vitodens with the new Viessmann One Base platform has an integral WiFi interface.

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. A further benefit is that Viessmann offers a five year guarantee covering the whole system as soon as connectivity is set up.
