Design & Technology

Condensing technology offers the greatest energy efficiency. Taking the overall investment and current energy prices into consideration, condensing technology is the most economical alternative.

Viessmann gas condensing boilers convert up to 98 percent of the natural gas used into heat. Condensing technology is also futureproof, as it is possible to combine conventional fuels with biofuels such as bio natural gas.

This is why you should invest today in advanced condensing technology. The savings you can make are considerable. Make an effective contribution towards the sustained protection of our climate by preventing unnecessary CO2 emissions.

Viessmann always offers the right solution – with its comprehensive range of medium and industrial/commercial boilers as well as powerful heating systems for sustainable fuels, in particular biomass.

A perfect match – System technology

"The whole is greater than the sum of its parts". Following this philosophy, Viessmann supplies more than high quality, reliable and effective heating components. In fact, all products are part of a matching total concept, where all components complement one another. After all, only perfect interaction between all system components can draw out the maximum potential of our innovative leading technology.

Viessmann system technology incorporates everything you need for a reliable and economical heating system: From the Vitotronic control unit with wireless remote control, powerful Vitocell DHW cylinders for the highest DHW convenience, right up to high grade solar thermal systems for cost effective central heating backup.

Comfortable and powerful Vitotronic control

The Vitotronic control system with a large colour touch display allows fast commissioning by means of an assistance function as well as simple operation. Via the integrated LAN interface, the boiler can be directly connected to the Internet for remote monitoring. The Vitosoft 300 service tool communicates directly via WLAN. Energy consumption can be easily viewed via the control energy cockpit.

Intelligent temperature regulation

Whilst older boilers have to be operated with a constantly high boiler water temperature of up to 90°C, the temperature of the boiler water in Viessmann gas heating systems is regulated according to the outside temperature.
