Compact and reliable wall-mounted gas condensing boilers

As a large manufacturer with many years of experience in the field, VIESSMANN knows what matters when it comes to manufacturing gas condensing boilers. You can rely on the quality of Viessmann products. Vitodens wall-mounted boilers represent not only innovative technology and performance, but also reliability and durability. Thanks to modern modules, the wall-mounted gas condensing boiler saves a lot of space and can also be installed in small niches. No side clearances are needed for servicing; all connections are easily accessible from the front. This makes Vitodens the ideal solution for modernising apartments or single-family homes.

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

The new MatriX-Plus burner is distinguished mainly by efficient operation, but also by reduced pollution and noise. The special stainless steel surface of the MatriX burner is resistant to high temperatures, thereby guaranteeing the reliability of the appliance and high performance over a long time. Another technical innovation from Viessmann is the fully automatic Lambda Pro combustion control. It automatically adapts to all gas types and ensures clean and efficient continuous combustion.

Inox-Radial stainless steel heat exchanger: efficient and durable

The corrosion-resistant Inox-Radial stainless steel heat exchanger is the „heart“ of the Vitodens boiler. It efficiently converts the energy used into heat and certainly stands out with the durability and high quality offered by stainless steel.

Easy operation with a 7-segment display

The 7-segment LCD display of the new electronic control features the sleek "Blackpanel" design, with very simple and easy-to-understand operation. Heating systems with direct and / or mixed heating circuits can be conveniently controlled.

Save energy, enjoy comfort and security with ViCare

Vitodens gas condensing boilers with the new electronics platform have an integrated WLAN interface. If desired, the heating system is connected directly to the internet via this interface. With the ViCare app, operating the heating is very easy and intuitive. It sets the course for digital services and is in direct contact with the local heating specialist. The ViCare app provides information on the current operating status of the heating system, time programmes for heating and hot water preparation, and helps reduce energy costs. It is compatible with almost all iOS and Android devices. ViCare uses the smartphone's GPS * function on request and recognises the distance to the heating system. If the specified distances are exceeded, the room temperature is automatically reduced.
